gbrand Posted January 3, 2006 Share Posted January 3, 2006 burned or carboned valve maybe? Try the wet compression trick, squirt in a little oil , and if compression raises it is a ring issue not valves. Let us know how you make out/fix of not/etc Link to comment Share on other sites More sharing options...
nipper Posted January 3, 2006 Share Posted January 3, 2006 could be the beginngs of a head gasket issue too . Did you notice if the spark plug was cleaner then the other plugs? nipper Link to comment Share on other sites More sharing options...
DerFahrer Posted January 3, 2006 Share Posted January 3, 2006 Could be a burnt exhaust valve. Any bad exhaust leaks in the Y-pipe? Could be a headgasket. Have the coolant sniffed for exhaust hydrocarbons. Could be the rings, although I doubt it. It's rare for one ring to go bad. Do the oil-squirt test to be 100% sure, but I still think it's one of the other two... Link to comment Share on other sites More sharing options...
monstaru Posted January 3, 2006 Author Share Posted January 3, 2006 the spark plug was actually dirtier than the other plugs, which iirc would suggest an exhaust valve stick? there is a hiss from the y-pipe,do not know where though...could be further back though....

AlpineRaven Posted January 4, 2006 Share Posted January 4, 2006 You'll need to do wet compression test before confirmation... Another question - does it burn oil? or blow large amount of smoke at cold startup? Cheers AP Link to comment Share on other sites More sharing options...
