View Full Version : MR2 smokes slightly while idling

I bought a 92 MR2 turbo with 61,000 miles on it and as far I can tell the only problem is some internal cosmetic wear and tear. But when I started to push the car a little to around 6-7k rpms the car started to smoke while idling. The smoke is white/blue, more on the white side. The only modifications done is a greddy turbo timer. The timing belt has been changed and the ac has been updated. Got any ideas why it would be smokin? It only smokes while idling. :|

Hmmm could be Valve seals??? Did this just start happening?

Smoke smell like burned oil? Oil entering the engine and combusting with the fuel probably causes blue smoke...


hmn what else...


coolant/water vaporized while in combusting chainbur with fuel maybe...


id have to agree check valve seals, and do a compression check just to be on a safe side... who knows maybe ya got a cracked head or block...

( highly unlikely but who knows? )

Could be a blown turbo, you can check shaft play on the turbo by taking off the intake tube and wiggling the compressor wheel. If the wheel touches the inner housing, it's shot.

I don't think that its the turbo. But I do think it is the valve seals or maybe a bent valve. I don't think its a bent valve though, just the seals. The car smokes only when the turbo timer kicks in to cool the car down, and it doesn't smoke while its idling on its own.
How much work do you guys think a new valve seal work take to replace? and how much do they usually go for? :|

Valve seals are cheap, the labor to replace them is not. It would cost like $200-400 parts and labor at the dealer.

I would like to do it myself, but I just don't know how to do it :| . Do you guys know anyone who is familiar with 2s? Or maybe a shop around the Sarasota/Bradenton/Tampa Bay area to help? I'm currently thinking about taking the car to "Lowe's Automotive" in Sarasota. (That's where I live). The shop has helped alot of RX-7s hit 9s. Really they specialize in rotaries but can work on just about any type of car. Anyway, its probably the valve seals, so would it be the intake valve or exhaust valve seal? I would think it would be the intake valve seal, but I'm no mechanic. And what is involved in replacing the valve seal? The local dealer at Gettle Toyota of Sarasota claims that it would cost me about 750 just for labor! Which I think is bullshit.

I have seen a bad PCV valve cause a smoking condition.

Have you tried that yet? Does it still smoke @ idle?

If it smokes during idle like at lights and stops when you give it gas then most definately check out your turbo. You probably ran it a little low on oil and boosted up.

Blue smoke = oil
White smoke = coolant
Greyish = fuel

If your car smokes on startup and when you let it sit for a bit then it might be the valve stem seals, but since its during idle definately check out the turbo.

Its probaly a head gasket.do a compression test.the mr2s and supras are bad about blowing the head gaskets,if it is a head gasket perfect time to upgrade.hope this helps..later bro,Ray

so much misleading information......

well, the MkIII supras did have some HG issues....but sheesh, not THAT bad.

also agree that its not the valve seals if its doing it normally at idle. Valve seals are more of a startup thing.....blue puff of smoke.

I'm a little late here but I had a similar problem in the honda, and it was caused by a blown turbo seals. Oil appearently sits in the turbo and builds up, then at idle, it is burnt and smokes @ an idle. If you REV your engine.. you will see a shitload of smoke go out.. and then it will stop smoking for about 30 seconds-3 minutes. If thats the case, then it is most-likely the turbo seals. Which can be replaced by many places :-D Hope this helped any!
