Slight amount of smoke from engine area

Mar 23, 2005 6 Replies

Folks, Just bought a 2nd hand 1996 Subaru Legacy 250T. All seems to run very nicely, however I have noticed that there seems to be a small amount of smoke coming from the engine bay. Not a huge amount, but enough to see coming through the sides of the hood.



Various people have mentioned that it's likely to be some spilt oil or more likely a silicon spray burning off. Any thoughts on this? The engine seems to be running fine, no over heating or anything.



My current approach is to keep an eye on it and see if it goes away over the next few days - or should I have it straight into the garage for a check over, despite the fact it's just had a full service?



Cheers Rupert


Hi,

Is the engine clean enough to see oil leaks? If not, you might want to give it a good bath so you can watch for leaks. Seems the places Subies are most prone to leak are in areas where the oil drips down onto the exhaust system, causing the smoke and hot smells. Cam seals are especially problematic on mine... oil leaks at the cam, runs down inside the cover, exits far away from the source, directly onto the exhaust.

Rupert, first check the front halfshafts. When the boots sorrounding the universal joins on these break the grease they contain is flung out & some can land on the exhaust pipe,causing smoke.

Then check for leaks around the crankshaft & camshafts. The seals on these tend to start to leak around 80K miles, & the oil that seeps out can be blown back onto the exhaust, causing smoke.

Let us know what you find

Thanks for the replies - seems it was a side cover gasket that was leaking, reseller is doing the repairs free.
