V40 breather problems

Weerab81 · Jul 12th, 2015, 17:35

Hello everyone.
I've got problems with my 1991 t40 and the breather system.
I had it into a garage and they replaced the oil separator as he said it was full of cream and really thick.so after a wash of the engine an a week later I was still getting a burning oil smell from the engine bay esp at the rear of it. After a bit of investigating a found a slow n stead drip of oil from the exhaust manifold at no 2 cylinder and I also found the breather on the cam cover had blown off and also on occasions the dipstick would be popped up.
so today I stripped the car to get access to the breather pipes and oil separator. I found I little hard debris in the pipe from the cam cover to the o/s but nothing more. Is there anything I've missed. Also, a little different but one day I had no turbo and after removing the heat shield and burning my fingers off I found the actuator wasn't connected to the gate on the exhaust. I fixed this with an r clip. But the actuator seems to want to pull up instead of slide out and in.
any help guys would very appreciated.

Should aslo note that the traction control light and eml is on too.

The things you describe lend themselves to being a headgasket issue.

Getting a compression test done on sat as someone suggested piston rings as there has been a splatter of oil on boot lid n bumper from exhaust when I've got the foot Down.. also said that could be why pressure is high in crankcase.

I hope not. I love this motor. Spent near 700 on it to get it through an mot as previous owner neglected it.

Would a head gasket cause such pressure in the crankcase to blow dipstick out and top breather hose? Also water is good and not put oil in it since service 4 weeks ago. There isn't any smoke (there was as I had a miss fire at 4-5000 revs. Changed plugs n sorted that) but no blue smoke but it's giving splatters of oil on back end of car, then I thought, if it's piston rings surely the engine would burn the oil? No? Also when I took of the inlet pipe to the manifold there is oil residue in the chamber.

Well I suppose I better finish this post since everyone's waiting with baited breath n would like to thank everyone for there help with this problem I had
The breather from the top of oil separator that runs with a water pipe round the cylinder head to the inlet pipe to turbo, was clogged so I have been to the scrap yard and picked up a hose to fit (a powersteering hose from a pug boxer van) bypassed the existing pipe started it up and ran rough at idle at first but soon settled. Took it a run up the motorway to clear the exhaust etc, and now it runs perfect with no leaks no smoke or spitting from the rear even at 140+
