boost problem

Hi!

 

I've just reinstalled my TT engine after having it out for some major surgery.

I've hit one snag that i'm not sure about....

 

I let the engine get up to temperature, and then rev it a little, the boost gauge (standard nissan crap) will move a little to the right showing small amount of positive boost, then will swing back halfway to the left before settling back at zero again.

This is done when the car is stationary, I don't want to drive it until i'm sure!

Is this normal, I honestly can't remember as i've not driven the car in approx 6 months! smile.gif

Could it be in safety boost, or possibly a leak in the intake system somewhere?

 

I get a 55, all clear on the ECU diag.

 

Any ideas???

 

Cheers,

Ben.

    It probably needs something to push against, if you get my meaning. Try with it in gear and the brakes on. Best to be pointing out of the garaage though ! wink.gif

    sounds normal..

    you won't be able to get a lot over 2-3 psi of positive boost when the engine is not under load.
