Hello all,
So got an mr2 around 2 weeks ago. It's a y reg with 77 000 ( if we believe it).
Anyway it smokes a bit and I'm assuming it needs a engine rebuild.
But with the help of people on here I'm trying all the other things first !
So the symptoms are white smoke puffing away when ticking over, and when thrashed some black smoke.
So far I have
Cleaned the cold start valve or whatever it's called under throttle body.
New plugs and oil
New injectors.
Maff cleaned with carb cleaner
Nothing has solved it.
I had a mechanic around today and he's not convinced it's oil use.
He thinks it's a fuel issue. Anyway he's thinking that my cat on exhaust has failed and it's messing up my readings making it run rich,
He also is unsure if head gaskets going ( that can give white smoke ) as it seemed very pressurised when lid taken off expansion tank.
He's going to come back with a sniffer to see if head gasket has gone.
I'll keep you up dated in case any other new owners have a similar issue !
Head gasket is unlikely to fail unless it's been seriously overheated - they're mls.
What's that saying about walking and quacking like a duck?
It's a smoking 1zz!
Precats blocked perhaps?
Have you changed the air filter?
