Right was in traffic today and noticed a puff of blue smoke when pulling off it seems fine when moving and on idle just pulling off in 1st or in reverse.

Noticed the oil is fine and still on the same level as when i serviced it in March.

Just wondering what it could be?? :homer:

Valve stem seals, Rings, turbo seals :confused:

Smoke is just coming from the exhaust when pulling off, haven't really noticed it when booting it or downshift to be honest.

Im hop[ing its turbo as i have a new turbo kit going on soon in time for the trackday as i am hoping to run this engine over the winter while i rebuild my other engine.

So how do people know what the problem is?

Whats symptoms of valve seals, turbo seals and rings?

I hope its just turbo i just need to know my engine will be up for running the vf at a bar for a few months while i rebuild, as i have good compression over the 4 cylinders.

I have new oil stem seals for my other head :cool:

Just need this engine to last me until early parts of next year when my build is ready and turbo needs to last until i can get a clutch and fit my new vf turbo :)

Car is being a bit of a bitch lately now this has happened and clutch has started slipping after 15 months running 1 bar :p i guess the turbo and clutch has lasted quite a while if they are originals :)

Right, I've read a LOT of posts about blue smoke and the causes. I have the same problem, so trying to find out the most likely cause. I have a 4EFTE with a 5E top end. Now, the valve stem seals were done in 2007 and the car hasn't done much mileage since then (although a previous owner could have thrashed it for all I know). The turbo has just had a full rebuild with new bearings (not sure about the seals cos' I bought the kit myself and don't know what the seals actually look like (pics anyone?). A colleague at work who knows turbos rebuilt it for me.

There are 3 main thought processes:

1. Turbo seals
2. Valve stem seals
3. Piston rings

Not to sound condescending or anything, but a simple way of checking the general condition of the engine is to look at the condition of the spark plugs. Tan colour is about right, whitish deposits are a sign of rings/valve seals. Mine are all tannish in colour, with some grey tinges on the ground electrode (all seems fine), but I'm getting quite a lot of blue smoke, especially after boost. I had the turbo rebuilt because of oil in the intercooler/pipes, this is still happening now, so I'm a bit confused.:confused: Just hope it's only the turbo still.
