copemech Posted November 17, 2008 Report Share Posted November 17, 2008 (edited) Reports from others : Check valve lash after run in. A low tickover may cause engagement of the decompressor on the cam. Some have reported timing chain rattle and replaced the tensioner it seems, not sure about this as compared to the second issue? Oh, and something about insuring the vent off the head is not being pinched off! This could cause blowby the gaskets!

I would say some light tick may be normal . If your vent was pinched, the cover should be ok otherwise. Do you have a local dealer that may advise? As we do not know where you are from your profile?

den Posted November 18, 2008 Author Report Share Posted November 18, 2008 hi im from barton on humber south humberside! I have sent aload of emails out and TRIALS UK was the only one who came back and has helped me up to now. with out seeing it he recons the timing chain tensioner as well. the oil seems to be coming from just behind the top of the triangular side plate on the barrel either that or the head gasket behind it as it overlaps. i have checket the breather pipe and it was not pinched! so im a bit confused, i have emailed sherco regarding the problem and requested a manual as there is not one for a 4t 08 on there. im kind of hoping that it is the tensioner and the side plate gasket! but never the less im a worried bloke at this point. dont fancy droping the engine at all! thanks again den PS ill square my profile up Quote Link to comment Share on other sites More sharing options...
