GordonC 20 Posted April 2, 2011 Report Share Posted April 2, 2011 I know this is my first post but I have been on here for a while and finally signed up today as I'm needing a bit of advice.Well I stripped my vr6 down and it appears both the upper and lower timing chains have snapped. Dont know whats caused it to happen as the engine was only on 98k but here are some pictures of the valves and a bit of the chain tensioner I found inside.I'm going to replace all the valves but will I need new valve seats or new lifters aswell ?Also what can I use to clean the whole head to get all the oil and carbon deposits off ? Can I just use any degreaser or what ?What can I use to clean the top of the pistons to get all the carbon off aswell ?Thanks guys Link to post Share on other sites
b road blaster 0 Posted April 2, 2011 Report Share Posted April 2, 2011 not sure on what you would need to do to the valves or lifter but i would use pertol and a scoreing pad on the piston heads one of the plastic ones i'm sure one of the tech heads will be along later to help with other parts mate Link to post Share on other sites
bungy 2 Posted April 2, 2011 Report Share Posted April 2, 2011 I can't see the pictures as i'm at work at the moment but maybe worth sourcing another engine if fixing the one you have is too damaged. Link to post Share on other sites
cabrioman 6 Posted April 2, 2011 Report Share Posted April 2, 2011 as the valves are going to be out mite aswell get it skimmed mate ..... should only need to replace the valves no need to replace the guides or springs ... Link to post Share on other sites
GordonC 20 Posted April 5, 2011 Author Report Share Posted April 5, 2011 Alright I was thinking of getting it skimmed anyway, Thanks guys Link to post Share on other sites
ROBSVENTO 0 Posted April 5, 2011 Report Share Posted April 5, 2011 I have a head that has been skimmed and pressure tested just 4 weeks ago and is 100% pucka, also had the valves re seated and new stem seals fitted.. Has 2.9 corrado cams in there aswell for extra bhp and all the cam pullys aswell.. Ill do it for £150 postedjust a case of a gasket and new bolts and away you go...Pm me if needed mate, once paid you could have it by the weekend, save you getting new valves and lifters etc.. I have a receipt from the engineer for proof of the work i had done...Pm me your number if you want to talk about it and ill give you a ring... Link to post Share on other sites
J5KE F 0 Posted April 5, 2011 Report Share Posted April 5, 2011 I would have suggested another head than messing about with a chain damaged one.. I have only ever heard of chains breaking once before and there was no sign that it was going to go.. Link to post Share on other sites
