Oily smoke
« on: 04 April 2013, 09:34:03 PM »
Hi all, I need to pick your brains.
95 2.0 EP 2001. 165K Mls
70mls into a trip I slowed for a low speed limit twisty bit of road.
I put out vast clouds of blue smoke, initial conclusion was Turbo seals. Due to traffic and the road I had to continue for 4 miles, I could hardly see a yellow DHL van behind me.
Pulled into a service station, left her running and was still generating a good bit of smoke. Turned off and went in to buy oil. Now, I could purchase a breakfast roll, Madeira cake and any quantity of rubbish but no bleedin oil.
After 10 minutes I fired her up again, no smoke and running like a watch. I drove 9 miles and got a can of oil. Topped up with 2 litres.
I drove for a further 70 miles, running fine. Did my business and left, as I pulled onto the road and I put out another cloud of oily smoke, I had to keep going due to traffic, made a decision to proceed to see what would happen, the smoke stopped after a mile and hasn’t been a problem for 400 miles.
I read a post that identified the oil pressure relief valve as a suspect in 95 smoking, is this the case and if so where is it and what can be done with it.
Any other causes would be gratefully received.
Recent history is: The turbo seems to be fine, sump was dropped 6 months ago, plenty of sludge which had seized the turbo. The turbo was recovered and has been fine since. Fitted rev 6 breather kit.

Thanks in advance

Mark

Hi,

Spring valve for oil pressure is behind front pulley on underside. Check seal, clean and replace. Good place to start, I hope its not your turbo.

Thanks Steve, she did it again today, I seem to have white smoke and blue smoke.
I'll try the pressure relief valve.
How does the pressure release valve result in smoke, does it vent to the sump or elsewhere.
