james Posted July 28, 2010 Share Posted July 28, 2010 A spark plug shorted by excessive oil entering the combustion chamber is shown below.http://www.skatemalaysia.com/planbmedia/plugbasah.jpg This is often caused by piston rings or cylinder walls that are badly worn. Oil may also be pulled into the chamber because of excessive clearance in the valve stem guides, or badly worn valve stem seals. If the PCV valve is plugged or inoperative, it can cause a buildup of crankcase pressure. This condition can force oil and oil vapors past the rings and valve guides into the combustion chamber.Also checkhttp://www.spark-plugs.co.uk/pages/tech ... gnosis.htm Link to comment Share on other sites More sharing options...

civicturbo79 Posted July 28, 2010 Share Posted July 28, 2010 Did the plug lead have oil on it , if so its just the rocker cover seals ,you have one that goes around the outer edge and 4 x o rings that go around the plug holes one of them will be leaking and filling up chamber.

s88hon Posted July 28, 2010 Share Posted July 28, 2010 I reckon its as simple as a spark plug seal. Very common on B series. Link to comment Share on other sites More sharing options...
lacos Posted July 29, 2010 Author Share Posted July 29, 2010 no oil on lead so what next , compression test plus the valve clearance needs doing the intake side sounds quite noise Link to comment Share on other sites More sharing options...
jalesi2001 Posted August 13, 2010 Share Posted August 13, 2010 Spark plug seals, like has already been said, very common on B series engines. Link to comment Share on other sites More sharing options...
lacos Posted August 13, 2010 Author Share Posted August 13, 2010 cheers lads will change gaskets when i get valve clearance done see if it cures it but like i said i think a comp test will reassure me that its not the rings ,,, i think it would smoke a lot more, what other symptoms would there be if it was the rings Link to comment Share on other sites More sharing options...
jalesi2001 Posted August 13, 2010 Share Posted August 13, 2010 Lack of power and smoke i guess, might find it hard to start in the mornings if there is a lack of compression?? Link to comment Share on other sites More sharing options...
s88hon Posted August 14, 2010 Share Posted August 14, 2010 Are you actually losing alot of oil? thats a surefire way to assume that somethings wrong. When you vtec get someone to follow and see if any blue smoke plumes out on WOT.Then its the rings.. However, loads of old Series tends to be valve guides or stem seals.You'll know if its the valvetrain as when you back off gas, blue smoke should also emit out.
