Problems folk: Pajero 2.8L owes me nothing - 525000 kms - reliable - never broken down.

Head gasket done 200k - leaking oil from hi press line up block therefore head gasket had to be replaced - head cleaned, crack check etc - turbo recond - no problem.

425K - clutch finally gave out 10k from home drove home and turned off key - decided get engine done, clutch etc. Wasn't burning excessive oil. Was burning though

Head not done - block rebuild - reconditioned - everything - was still burning oil - thought must be head, valve guides.

525K - oil consumption now 1l per 80 -100km - burning - no oil leak - nil, nilt oil leak. normal running was puffing blue smoke but go up hill and at night can see plumes of smoke. Brand new head, new valves, top end brand new - car running beautifully but still burning excessive oil - rang Mitsuibishi - no help there reckons can only be oil rings!! Yes - logically but no not that amount. No scoring og bore seen when head done, no leaking of petrol down past rings with static petrol test - with rattling old oil rings you could burn that much. Mechanic wants to pull engine and examine oil rings - I think barking up wrong tree.

Any clues - starts beautifully and has always - yes plume smoke whenever start!!! oil is getting in there somewhere.

Where else from - only other place - turbo and tappet cover breather - turbo was recond - perhaps missing something and is blowing throu turbo or blowing through breather into air intake. Never boiled, never over heated, never uses water ever. So clues - I just don't think that much oil can go past oil rings - something is being missed by those who should know!!!!!!

Too much like valve guides to be ignored!! Sometimes the wrong size has been installed when reco'd (check to see what size applies to your particular engine number then ask the mech. what was installed). Good luck.

with your oil problem it could be your t/c gasket, i had the same type of problem , oil was leaking onto the manifolds and was burning and you could smell it really bad then i had the t/c gasket repaired and it doesn't do it anymore
