SteveRK Posted April 6, 2010 Share Posted April 6, 2010 Gents Couple of questions i would appreciate some input on please - its that ol' chestnut Rover V8 cylinder heads! Pulled the nearside head off today, well not literally but took a short cut and left the inlet manifold on. 170,000 miles on clock. do the brownish the marks on the inlet manifold side indicate leakage?? and what seems strange is that the tin gasket protrudes into the bores - almost as if it has a smaller bore (3.5 lire?) gasket fitted??? The front inlet manifold port indicates a leaking injector as there is a cleanish line in the inlet track where it joins the head. The cleaner part of the front piston might validate this? I had all the injectors 'serviced' a 1000 miles ago so I hope this is evidence of a historical problem, not current. all the valves seem to be in remarkable good condition with no obvious signs of leakage.

landy V8 Posted April 6, 2010 Share Posted April 6, 2010 looks like someone has fitted a 3.5 gasket.how many bolts were holding the heads down?you don't need to fit the outer bolts.you can fit them just to plug the holes but don't torque them down.they can warp the head and then the gasket won't seal on the inlet manifold side.

vougese39 Posted April 11, 2010 Share Posted April 11, 2010 throw the third row of head bolts away not needed yes wrong gaskets i would be inclined to check the cam for wear at that milage Quote Link to comment Share on other sites More sharing options...
SteveRK Posted April 12, 2010 Author Share Posted April 12, 2010 I knew it would happen - commence escalation procedures - offside rearmost head bolt slipped on the socket and rounded the edges so engine out. The bolts were so tight i had to use a motorcycle stanchion slid over the end of a half inch socket wrench to get the leverage. Quote Link to comment Share on other sites More sharing options...
