No boost

[Unknownvr4]

Well i finally got the vr4 running again, and it was running good for a while. I had a EBC on it for a while and i was trying to set it. Well setting it wasnt doing any good cause it would just overboost every time. On the last pull, it didnt boost any and started smoking blue smoke.

Checked all IC pipes and a buddy told me to put a MBC on instead of the EBC. So i did and tried another pull and still no boost.

Im hoping not but im thinking probably a blown turbo.. or wastegates stuck open.

Please, any help is appreciated.

Pressure test the IC system


If that is good then check for oil in the piping and the downpipe

Man! Just no luck lately. I'm with Paul though, hope you get it sorted out and the problems stop.

It is a possibly that your wastegates are staying open.

How would I go about seeing/fixing this problem?

Unfortunaltely, replacing the waste gate actuators is usually the best soloution to it. to see if this is the problem though, put some air to them with a compressor with a regulator. slowly increase the pressure to see if there is any movement, if they don't move try removing one of them from the turbo to see if they're the culprit or if the flappers shaft itself is siezed. Usually it's the actuator, I myself have never seen a siezed flapper Hope it helps man.
