Thread: Pommie Provent

So my car recently started to blow whitish smoke at start up, and blue tinged smoke on boost.

The cam carrier also started to weep oil.

After lots of messing about thinking I'd blown a turbo seal I decided to remove the lid from the provent and test again.

First of all I was greeted by loads of horrible oily sludge:


This had obviously also been blowing out of the top over pressure port...

So my guess is that I've managed to clog the provent filter already!

Anyhow, filter out, and all of the smoke issues went away.

Bit miffed because I'm now going to get an oily IC again.

So, anyone else had this experience?

Could this be because the oil drain was open to air, therefore there was no suction on the underside of the filter?

Why is my engine so breathy, eve though performance is fantastic? - checking oil pressure next in case the pump relief valve is stuck.

Can you get your oil tested, does the engine use coolant, that sludge looks like it could be water in it, but cant Tell from a picture, if it is just carbon then you could have serious internal issue ie rings. If that Coolant in oil then there maybe cracked some where

On closer look I'. Sure , can see water droplets and also green coolant around the thread of your crank.case filter, re reading your story ads up to white smoke on start up actually burning coolant

Doesn't appear to be loosing coolant - there's certainly no coolant smell/color to the sludge (but not sure there would be?). I was under the impression that there's a lot of water vapour in blow by anyway?

Regarding rings, I hope not! Would've thought I'd have performance issues though?

Nanocom suggest everything is in balance, none of the injectors are having to compensate for a poor pot?

Guess there's a few things to do:

oil pressure test
oil test
compression test

That green bit is a reflection - my coolant is pink OAT.

Just to add, the whitish smoke was almost certainly unburnt derv, it stank and burnt my nose & eyes.

Different engine, but the provent on my Isuzu 4bd1 ends up with just liquid oil in it - nothing like the sludge you are getting in yours.

What sort of driving are you doing? Lots of short trips perhaps? Looks like its not getting hot enough to dry the moisture out.

Usually a 3 mile drive to dump the kids followed by 22 mile commnute to work 50/50 A roads & Motorway but quite often stop start (but engine always running!). Then 25 mile commute back home, again stop start.
