What causes oil to come out the exhaust?

oil is leaking down past your valve stem seals or past your piston rings.Originally posted by southsidecb7z View Post

Look for oil coming out of the exhaust...
Keep an eye on your oil level. Using a thicker grade oil may help to some degree.Regards from Oz,

Lol...its deff. shooting oil out the exhaust as stated above...i just want to check to find out what exactly the issue is...also it leaks oil anyway from somewhere in the lower timing chain cover area so its hard to tell exactly how much is spraying out the exhaustOriginally posted by johnl View Post

do a wet and dry compression test! do a dry test first! and then do a wet test! on the wet test add about a tbs or 2 in the cylinder you are testing, if the compression #'s go up from say dry= 120psi to wet= 190. that is just an example there has to be at least a 30+psi change aprox for the rings to be bad. if there is only like say a 5-10 psi change it would be your valve guide seals!Originally posted by southsidecb7z View Post

thanks mane, sounds a bit complicated but ill try, you mean add a tbs of water right? It is the stock engine with 250,000 + but i still highly doubt its the rings...i think a head job would do the trick and while im at it fix the damn oil leak!Originally posted by sleepycb7 View Postdo a wet and dry compression test! do a dry test first! and then do a wet test! on the wet test add about a tbs or 2 in the cylinder you are testing, if the compression #'s go up from say dry= 120psi to wet= 190. that is just an example there has to be at least a 30+psi change aprox for the rings to be bad. if there is only like say a 5-10 psi change it would be your valve guide seals!

is it burning it or shooting it out the exhaust pipe?Comment

Seems strange that it's blowing oil out the back......usually any oil will burn off before it reaches the end and you'll have blueish smoke. Are you sure it's blowing oil and not dirty water or fuel?
If it IS blowing OIL, then you have a very fast leak for it to be enough quantity to not get burned off in the exhaust system.....
dry/wet compression test should tell you for sure though!My Member's Ride Thread
