Supra-Brett Posted September 18, 2011 Share Posted September 18, 2011 Took the car on a long run the other day. Smelt a burning oil type smell whilst at the lights and then when stopped I opened the bonnet and noticed a haze and a stronger smoky smell. Noticed a small oil leak towards the top rear of the engine just above the exhaust manifold heat shield. Is this a failed rocker cover seal?

Scooter Posted September 18, 2011 Share Posted September 18, 2011 yes, you can nip up (go gently) the bolts in the vicinity and I would take off the rear speak plug cover and check out for oil ingress into the cylinder head valley. it will run down there and flick back onto the exhaust to give the smell/fumes.

Scooter Posted September 18, 2011 Share Posted September 18, 2011 if you can't fix soon then I would use a good degreaser and thoroughly clean the area all the way down to the sump and backwards ie any visible oil, this should mean that unless its really leaking badly that you should avoid much of the smell/fumes next time out.

OK thanks Wont i have to take the inlet manifold off too (think that what its called - attached to the air filter - Its an N/A) in order to get to the bolts that need to be tightened? Also, i supposedly had the rocker cover gaskets replaced 2 years ago by Toyota GT and ive only done about 5000miles since then. Is that normal?

Dnk Posted September 18, 2011 Share Posted September 18, 2011 Brake cleaner works quite well. If it were me i'd bite the bullet and get 2 new cam cover gaskets including the seals that go on the bolts and also pop some new plugs in it at the same time Ignore the above if you've had them replaced and try just carefully nipping up the bolts Quote Link to comment Share on other sites More sharing options...
Konrad Posted September 18, 2011 Share Posted September 18, 2011 Original toyota cam cover gaskets are cheap enough and it's not that bad to take off throttle body and rest of the stuff If it's leaking around the corner it might be that someone forgot to put a bit of silicone to seal corners properly Quote Link to comment Share on other sites More sharing options...
Dnk Posted September 19, 2011 Share Posted September 19, 2011 You shouldn't need any silicon sealer if your using genuine o/e seals Quote Link to comment Share on other sites More sharing options...
Konrad Posted September 19, 2011 Share Posted September 19, 2011 I know, I'm putting a bit in the sharp corners anyway, saves me taking all out in case it would somehow try and leak. (learn it hard way, not on the supra tho :-P ). Quote Link to comment Share on other sites More sharing options...
