Look for the following visually:
-Look for rust around the whole car, especially the wheel wells,
Rust can/is a problem on these cars.
-Look at rear of the car for sooty residue. This usually signifies a Ring
problem and loss of compression, this costs about 1600$(min) to have someone rebuild it.
A OILY residue could also signify worn Valve guides. If the car was cleaned it
may be hard to tell, so look for this after you drive it!!
-Look underneath the car for any body damage from being bottomed out and the like.
Another good idea is to check for past wreck damage by looking for repainted areas
or better yet take it to a place to check the integrity of the frame. If your
planning on doing some racing it's important to have a sound frame.
-Look underneath the engine/transmission area for oil, &/or transmission fluid leaks,
the oil cooler lines seem to go after years of use and the breather plug sometimes
comes loose on the transmission case, allowing transmission fluid to leak. Both
of these problems are expensive to fix. You have to buy or tap the transmission case
to fix the breather. If this problem exists you can usually smell it when it hits
the rear exhaust and burns after driven, kinda weird smell on drivers side.
-Be Wary of buying higher mileage MR2s that have not been run for 4+ months. During that
time hoses may have dried out, and once it starts to be really used again these can crack,
break, and cause problems and grief. (Low mileage is usually 50K-70K)
-Look around the engine for worn vacuum tubes that should be replaced.
-Look at the where the distributor attaches to the head (round thing with the spark plug
cables come out of). See if there is evidence of oil leaking. The seals of these
distributors tend to go, allowing oil from the head to seep into here and then out
into the engine area. This also reduces performance by interfering with rotor contacts.
-Look in the front (under spare tire) compartment for rust, and see if the tools are
present, as in the spare tire, tire rod, jack, etc.
-Check for signs that panels have been replaced and repainted. Sometimes panels get replaced,
hiding past wreck damage. You can usually tell because there is no seem sealent, and or
the paint color is different on the other side. I've found the front side panels to be
replaced often on slightly wrecked MR2s. It doesn't hurt to use CARFAX and find out
if the vehicle had been damaged (only if claimed).
-Look at the windsheild seals..make sure they are not cracked, and check inside for
evidence of water damage, or leakage. This happens often on older vehicles that
have the original seals. You should also lift up the interior carpet to check for
signs of rust, indicating a water leak. T-Top MKIs start leaking around seals.
-Look for damaged or bent rims.
-Look at the engine compartment and check for fluid leaks, cracked hoses, fluid levels,
rust, etc.
-The seats tend to have small rips, or tears by this time, especially the SHIFT BOOT. This
is normal, and the shift boot can still be purchased by toyota for 50$ or so. I know
it makes the inside look crappy but it's an easy fix, don't let it deter you! You
might even use this to help reduce the sell price!!
-If the car has T-Tops look for cracks around the body surrounding them..MR2s can develope
cracks from hard driving/cornering and such disregard for physics.
Look for the following by Operating the vehicle:
-Apply the brakes often and see if a vibration occurs, warped rotors happen often with
'85, '86 Mr2s ..Rotors are usually 45$ each. 87-89s have newer brake systems that
doesn't seem to have near as many problems. BE CAREFULL when torqueing down the wheels
on MKIs...don't over torque them or the rotors WILL warp.
-Pull up the parking brake and make sure it holds the car...frozen parking brake cables
are a constant taunt and aren't cheap to fix, nor is it easy to repair. In the winter
water that entered the brake cable through worn brake cable boots WILL freeze and lock
your rear brakes, allowing you to go nowhere until thawed. This goes double for MKIIs!
-Go through all the switches, especially the headlight, and wiper dials...they can easily
be broken or not work correctly due to design, and heavy use. Check that all meters
are working, speedometer, etc.. If it has power locks and windows, be sure to test them
also....window motors seem to wearing out more often on MkIs.
-While driving, hold the vehicle straight on a flat & straight road and let go of the wheel
(keep your hand near the wheel) and see if the car vears to one direction. If it stays
pretty much straight, you don't have any alignment problems, if it prefers a direction
then you need to get it aligned. (Make sure the road is nice and flat too!!)
-Turn on the stereo (if it has one) and make sure to turn the bass up to make sure the sub-
woofer works properly. I know plenty of MR2's who's subwoofer quit working or never
worked. The stereo system of 85-86(maybe 87s) only had a few speakers where 88-89 had
the newer stereo setup.
-Make sure the idle is smooth (keep in mind the MR2s idle higher than most cars.) and not
bouncing up and down. This can be a number of problems, but usually a vacuum leak.
-In each gear accelerate quickly and slow down quickly. This is to test the synchronizer
gears and linkeage on 5-spd manuals. Many MR2s have problems staying in 5th gear. The
later 88-89s toyota seems to have taken care of this.
-Check the clutch by seeing how well the clutch engages, and how far up your foot has to
come up before in does. (make sure it isn't slipping) Many Supercharged MR2s I've
tested have worn out clutchs...this is not as much a problem on the NA models.
-When Driving an SC, make sure the boost comes on smoothly and quickly. That "jet engine"
sound is normal *smirk*!! Full boost can be had in third & fourth gear.
-While the car is at rest but running...look under the engine area for leaks, and look at
the exhaust for white/ blue smoke...these are pretty good indications of engine
condition as far as the head, exhaust, & compression, goes. Blue smoke indicates blow
by problems, and/or loss of compression, due to ring wear & deterioration. Many '85-86
Mr2s I've seen, start developing this around 110K-140K miles! This is from wear and tear
on the engine. My own had a blow by problem. After a 30 mile drive the back
of the car would be covered with exhaust goo, and oil, both fresh and smoked!! Be
carefull with this one...it's expensive to fix, and sometimes cheaper to just buy
a new engine if you can't fix it yourself. NOTE: If you're a big DIY you can get a car
cheaper if it needs engine work, IF your willing to take on re-building or replacing the
engine and replace all the hoses and other cheap stuff while your at it.
-While the car is running, place the parking brake on and the clutch in nuetral. Wait a
little bit and see if you hear a slight crunching sound in the transmission area.
This is usually worn out clutch bearings, and is often a problem with earlier 2s.
-While driving or idling, listen for any clicking/clacking from the top of the engine. Older
mileage cars, that haven't had their regular valve maintenence tend to get noisy. This
costs a couple hundred from Toyota to do. If your a DIY it's actually pretty cheap, just
needing a couple of special tools, shims, a dial gauge, and patience.
-When in doubt get a fellow MR2 owner to test the car with you, and it never hurts to have
the compression checked before you buy...
As a final note, be sure ask for any available records for work performed on the car. IE. When the
timing belt was replaced, etc.
Many have been asking me exactly how to check the turbo's condition on the MR2 Turbo....SO I created a webpage that is devoted to checking the various problems listed here, especially checking the turbo condition...and some turbo 101!!
Sooo, you wanna sports car but don't have the cash? Well the second generation should fit you just fine, and your friends will be suprised when you tell them it only cost as much as their new & slow Dodge NEON! The '91 year is even more affordable now being in the 7-9k range. You'll be pleased to hear that the Normally Aspirated (NA) Version is probably the most reliable MR2 made, and you really have to search hard to find ones with problems (AKA Reliable Rocket). The "baby Ferrari" as the stronger brother with the turbo has been called, tends to take it's share of problems from wear and tear, and of course time. This is mainly due to the effects of an engine running aspiration (turbo or supercharger). Any labor needed on these engines will cost, so the DIY attitude will save yourself some cash. Keep in mind some of these pertain to the Turbo version and not the NA MR2.
Look for the following visually: -Check to see if the rear exhaust tips have allot of carbon buildup. This will be a black sooty residue. Some is Normal, as the MR2 naturally runs a little on the rich side. This can signify that the car is running too rich, caused by a failure or intermitent problem in any of these devices: Bad or Intermittend Air Flow Meter (AFM)(600$ new 225$ used)[Mine went bad] Oxygen sensor (only when engine warmed up) cold start injector switch(your computer think the car is always cold and therefore runs rich) MAP sensor EFI Coolant Temp sensor BOV, VTV.... It could also signify that the turbo is going, or gone bad, and is spitting oil into the air intake system, forcing it to ingest oil, decreasing performance. -Check the engine compartment for leaks around the valve cover, transmission case, and especially check for oil & such around the TURBO!!! I can't stress this enough, my MR2 turbo had these indications and sure enough the turbo bearing seals were gone, and the intake hoses/chambers had tons of oil puddles. Not to mention it didn't run the boost levels it once did. So be carefull, Toyota wants $2000 for this part!!! Around 500$ to rebuild the one you have. An upgraded turbo can be 1k-2.5K$ Keep in mind that until the engine is fully warmed up will the ECU let the boost go above 6-7 psi. The stock Turbo MR2 will produce (typically) 9-11 PSI of boost. -Check the interior for signs of water damage due to a worn out window seal and such. -Look in the wheel wells for worn out McPhearson strut boots (very common)!! -Look for dents / damage underneath the car. Have frame checked for integrity. -Check that the rotors are nice and clear, with plenty of pad left. Some MR2s have damaged rear rotors due to the parking brake freezing, and they drive it anyway! BAD BAD driver!! -Check all lights & windows for leaks/cracks, and make sure no fuses have been blown. If the USA mr2 has clear corner lenses, it's a normal JAPAN part mod. Check my pictures for a look. -If the car has new tires, be sure to check alignment when driving, many dealers use new tires to cover up old alignment problems. -If the MR2 is a NA and it has hole areas in the front grill area, someone may have modified it with fog lights and then removed them. -If any oddities arise, like modified components left on the vehicle, check their condition too. As these MR2s get cheaper and cheaper, people are doing more and more modifications. These can contain such mods as: +Some form of Low restriction Intake filter. (HKS Superflow, K&N, Apex'i, etc) *WARNING: Vehicles with the HKS Superflow, can have foreign particle build up that hurts engine components. This is because the filter does not do a good job at filtering dust/dirt and other particles. Several MR2 owners have found damaged engine bearings and such, down to the copper, because of the HKS and it's sucky dirt filtration. I suggest the K&N. +Performance rims, lowering springs and other suspension pieces. +Turbo Boost Controllers (some electronic, others are manual adjust valves.) +Turbo Timer (actually a good sign) designed to let car idle after you leave to cool down turbo +A NA MR2 with a 3S-GTE (turbo version) engine. +Gauges - boost, fuel pressure and the like. -When doubt, get a fellow MR2 owner to come look with you. Check the following while operating: -Make sure the car idles fine, and does not stamper, stuter, and watch that the RPMs are steady and smooth. I have found many MR2s who have a bad Cold start injector switch (mine did) and caused the car RPM to be erratic, and cause the car to hesitate due to richer fuel. The switch is about 103$!! -While driving, when boost comes on listen to see if there is any fast clacking(clicking) sound from the engine. This can be a bad Blow Off Valve. Which can cause hesitation. -If at any time, especially when cold the car bucks,and/or be limited on engine speed, and stall when moving. YOU PROBABLY HAVE A BAD AFM. This took me forever to diagnose, and because it was so intermittent and would usually go away once the car warms up, no one at Toyota or anywhere else could figure it out!! Since replacing mine the problem has totally dissappeared! I've seen four Turbo MR2s with this problem! NAs don't need to worry. Also, some previous owner may have damaged their AFMs, by unscrewing the connector instead of un-clipping it off! A REALLY bad AFM will trip the Engine light. A NA does not use a Air Flow Meter. -Test the the intake system for build-up (Throttle body & T-VIS system). You should feel a difference under acceleration between 3500-4000RPM. If it feels hesitant in this area you may have buildup problems affecting the T-VIS operation. See if the throttle is sticky at first...it may need cleaning. Higher mileage cars have more carbon & oil buildup, especially turbos. Some can hear the change when T-VIS flaps open up, but it's not near as pronounced as any VVTL-i or VTEC system. -Make sure the parking brake works and is not frozen. Meaning that with the brake released there are no signs that the rear calipers are still holding. Same as on MKI MR2. The parking brake cable boots can be gone letting in water which can freeze the cable to it's sheath, preventing the calipers from disengaging. Replace the boots, and cable or dry the cable, and lube to solve this problem. -Check the usual lights, A/C, radio, gauges. I found that the water temp gauge sending unit attched to the cooler lines tend to go out, thus leaving your gauge on Cold all the time. (Make sure all headlights come up, and fog lights on Turbos work)Some people have blown one channel of their stereo, letting one side work and not others. Check the CD player too, mine is now on the fritz!! -Make sure boost comes on smooth and quickly, without hesitation. If the car hesitates, and is not smooth, then it could signify a wastegate/Turbo problem...Any turbo over 65-80K miles is due to be rebuilt or replaced...if your running a old turbo, chances are upper range HP is lower, falling off sooner, and producing less boost that one in proper condition. The typical boost is between 8-11 PSI after warmed up. If only the stock boost guage is available i have found that the first big tick is around 0 PSI, halfway up is 4psi and the next big tic is 8psi, while nine is around the "+" sign. Full boost is usually available in third & fourth gears in the mid-upper RPM range. Check my How to check the turbo pageor e-mail me and I'll explain how to test the mechanical condition of the turbo. -My 91 Turbo has 151K miles and is going strong, but always go for a lower mileage car if you can.As a final note, be sure ask for any available records for work performed on the car. IE. When the timing belt was replaced, etc
