We have a Nisson safari 87 with 4.2 Deisel. Fitted with a Schwitzer S2A Turbo charger.
At idle after about 10-15 minutes it passes oil out the exhaust pipe.
I phoned up 2 reputable turbo companies in
Perth and they say it is a no no do not idle them for more than 5 minutes or it will oil up.
Followed their advice took it for a hard run, running full boost for about 5 k in second gear (auto) and then it all goes back to perfect again. This turbo is only 4 months old, engine k's is 121,000. The guy in WA that we bought kit from. All he says as response is that he has been fitting turbos for 25 years and it is our fault. He set up the boost to 9lbs. So my faith in him is not very good. No after sales service at all.
Seems that I must get the turbo looked at by someone else or do all turbos pass oil at idle?
BUT: one week off going around australia, I Noticed air bubbles coming from front RHand head at no 1.
So Head coming off Monday.
My mechanic looked at it so now suggests pull head of and set up head for turbo engine.
This engine fitted with DGas and turbo does not burn oil and has awsome power. As this is an import a 1987 model if we can believe the paperwork. Nisson themselves do not want to know because it is an import.
No
water in oil, and no air bubbles in radiator, just weeping between head and block. Has anyone else suffered this problem?
Great start before the holidays. I sure didnt need that.

Hi Morry,
Years ago I had a 2.8 diesel Rocky that was weeping between the head and block. Put some chemiweld in the radiator and had no more trouble. Saved me big dollars.
Good luck Pete

Hi Morry
I doubt that it would be your turbo, it is more likely to by a cylinder, maybe broken or worn compression rings. You will soon see when the manifolds are taken off and see where the oil is coming from.
Not much help i know but something to look at.

Another thing to check would be the crankcase ventilation pipes for oil, you will always have some in there but if you have a lot it may be worth cleaning them out and fitting a catch can.
Turbos develop near zero boost at idle, so I would think as your truck is a japanese import it would probably be suffering from glazed bores or stuck or broken rings. They do a lot of idleing in japan and as they are forced to replace their vehicles every couple of years preventative maintenance isn't high on the agenda. The speedos on a lot of them seem to loose KM between when the get pulled off the road and when some unknowing Gai Jin buys it.
Look at the
bright side, your not stuck in the middle of nowhere with a broken truck and no way of fixing it or getting home without removing the arms from your first born as payment.
A leaking head gasket at 21yrs old eh Geez you just cant get quality these days can you..........
Good luck with the repairs and the trip.

hi guzzi
have today removed the head it was leaking by the staines on the head. but never used any
water have found that the cross over pipe from turbo is oiled up as
well as the indution manifold .head being done also thinking of reringing the engine as
well as big end bearings .no oil in the exhaust side of the head only shows on the ex turboside . phoned the experts and have been advised that it is not the turbo just reassemble it then if the prob still exist take it to them to look at this a strange one regards morry
