AlpineRaven Posted November 28, 2005 Share Posted November 28, 2005 On one of EJ22 engine (Liberty aka legacy) that I have here, how do I find out if I have worn/blown valve stem/seals? Its done 250,000 kms (approx 154000mi) Thanks AP Quote Link to comment Share on other sites More sharing options...
nipper Posted November 28, 2005 Share Posted November 28, 2005 well first question is do you burn any oil. If you do do a wet dry compresion test, that will tell you if its rings or valve guides. If you do burn some oil, and a compression test shows good numbers with no or minor change between wet/dry then you can suspect the seals. ANother way is to pull a valve cover and inspect them. My guess is at the very least you have tired valve seals. What do you ask? nipper Quote Link to comment Share on other sites More sharing options...
Jim Padgett Posted November 28, 2005 Share Posted November 28, 2005 I had a 67 Mustang that would smoke for a second or two when starting after it had been turned off for a while. Other than that I could not tell I had a problem. Quote Link to comment Share on other sites More sharing options...
Tiny Clark Posted November 28, 2005 Share Posted November 28, 2005 You'd have oil on your lips. Sorry, couldn't help it, just in one of them moods. Usually it will do what Jim said, smoke at startup for a few seconds. If it keeps smoking, it's usually the rings. Quote Link to comment Share on other sites More sharing options...

I did an compression test about one half months ago and it did show good figures (mechanic said the compression is all fine) but the cylinder nbr 2 has more black on the exhaust (I took the pipe off to inspect) others are well burn't. ONly shows a puff of smoke for a few seconds at the cold startup. Not hot startup. Does loose a bit of oil but its using more than average. Is it easy job to replace the seals yourself? I'm aware about taking the heads off and fix the valve seals etc. Cheers AP Quote Link to comment Share on other sites More sharing options...
