Burning oil smell

I see you are in Queensland.....if you started smelling this last Saturday evening, there is a good chance it was my engine :eek:

Small breather pipe from the tappet cover vents to intake after the aircleaner (preturbo)

Uninformed - you may be on to something. On a serious note, whats up with yours?

I'll try run it without the filter i.e. to atm. I only get this smell when its working hard

I found oil on the underside of the charged air intake pipe... Quite a fair bit actually. I think this is the source of the burning oil smell. Question is why is there so much oil accumulating in the intake pipe and how can I stop this. Is this a sign that the turbo is substandard?

I also have oil residue coming out the top of the dipstick.

As previously mentioned the turbo oil return is tapped into the oil pump cover.

Cheers in advance,

If you have oil out the dipstick, you should check your blowby. It might be excessive and also causing your turbo to pass more oil than it should.

Hey Dougal often after a long drive I'll pull the filler plug on the tappet cover and inspect while running. Gases are only faintly visible. The engine, preturbo, never used oil and I haven't observed any significant drop in oil level with the turbo.

Any other means of properly checking blowby?

Perhaps I should mention that its a garrett replica turbo (I don't intend on running this long term). Also, before installing a 1.5mm flow restrictor in the turbo oil feed line, I had copious amounts of oil passing through the turbo. Blue smoke everywhere!!! Is this in itself common?

Cheers

First, unplug the breather from your intake and run it into a bottle of some kind. Go for a quick thrash and see what the bottle collects.

To measure crank-case pressure you can pull the dip-stick, put a hose on the tube and run that to a pressure gauge in the cabin. The gauge should read nothing if all is good.

A turbo that can't drain enough oil will blow smoke. When the oil backs up it ends up spewing into both the exhaust and intake.
