Baloo Posted April 2, 2007 Share Posted April 2, 2007 Hi All Took the 95 V8i on a longish run yesterday - beautiful ! Today though, after a short run noticed a rattle from the engine bay. Feared the worst ! However: Rattle does not seem to increase in intensity in time with revs increase, but does quicken intermittently under power and seems to be coming from the plenum chamber. Read somewhere that pipes in there can come loose and cause a hell of a noise. My local landy specialist thinks the same. Any other opinions here before I put this in to get the plenum chamber sorted. No performance problems and rattle def coming from around the plenum...... Many thanks Baloo Quote Link to comment Share on other sites More sharing options...
BogMonster Posted April 2, 2007 Share Posted April 2, 2007 I've heard of the trumpets coming loose too, though I have not seen it but then there aren't many V8s here. Not sure what the fix is though... fill 'er up with concrete that should stop the little beggars Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted April 2, 2007 Share Posted April 2, 2007 I've heard of this but never seen it, I would guess a quick wipe with carb cleaner and then sticking them back in with hylomar or loctite or somesuch would hold them in place.

Baloo Posted April 12, 2007 Author Share Posted April 12, 2007 I've heard of this but never seen it, I would guess a quick wipe with carb cleaner and then sticking them back in with hylomar or loctite or somesuch would hold them in place. Had the Plenum Chamber stripped and refitted today, with no probs found. Rattle is still present, done a lot of miles recently with no ill effects. Landy man thinks it could be a piston ring. Surely this would increase the noise in time with the engine ? Also, I've noticed that this rattle only comes in when engine is almost up to temp, not when cold. Any further ideas anyone ?

Bull Bar Cowboy Posted April 13, 2007 Share Posted April 13, 2007 As it only happens hot, it sound like one or more of the hydraulic tappets are not pressurising correctly……………..the noise should get worse with revs……….. if is got loads of miles then I suspect a top end overhaul is in order ………….. try an oil change, sometimes it has the desired effect. Also, if it has moon mileage on it, then wear in the rocker shafts and rockers can cuase a rattle, but that is less common. Ian Quote Link to comment Share on other sites More sharing options...

Ian Thanks Ian, will try an oil change. doesn't usually get worse with revs tho. Just approaching 80k, so watch this space ! Baloo Quote Link to comment Share on other sites More sharing options...
