Frustrating Day

[Abo Bob]

My rego runs out next saturday so I needed to fix all the cars problems which were:

1. Replace cracked rear rotor.

2. Fix exhaust leak - diagnosed as turbo to manifold gasket cos I could actually see the missing part.

3. Clean up after my dodgy catch can.

4. Also borrowed a GTR bov to test fit to see if my stocker is leaking and causing my gradual boost drop. I know not for rego but still needs to be done.

1. was pretty easy once I took the handbrake off. Doh!

3. Easy.

2. Was very proud of myself because I was able to replace the gasket without removing the turbo or exhaust, just undid the exhaust mount nearest the front.

4. Decided to go temporarily atmo because the GTR bov has a larger diameter outlet than the stocker. Confused myself when I installed it and realised I had an open pipe where the plumb back used to go but I used 4 thicknesses of heavyish plastic held on with a hose clamp to fix that.

Started her up and the bloody exhaust leak was still there!! WTF!! And, the car wouldn't idle properly.

I put my hand over the bov outlet and that cures the idling problem. What's going on there? Is it leaking? Is it supposed to?

I went for a drive and the exhaust leak seems to be less but it's confusing and annoying. I noticed that the face of the turbo where it mounts on to the manifold doesn't seem to be perfectly flat. Does this happen often? Can I get it machined flat?

So either the warping is too bad to fix with a new gasket, there was always another leak, or I just didn't tighten it up enough (which I don't think cos I did it pretty tight).

Arrgh!

if you havent pluged all the hoses back in to the stock bov, you will have a leak, so it wont idle.

My exhaust is EXTREMELY tight on my commodore, yet it still has a 3mm gap... Just keep tightening until it won't any more...

Hoses were plugged in.

How very confusing and annoying!

Bring your car to my Pink slip guy, nothing you said will stop it from happening. Call me.

The BOV will suck air in under vacuum at idle- I'm willing to bet this is what is messing with ur idle stability if you are still using an AFM

[Abo Bob]

That seems to be happening. It sucks.

Already gave you my advice on Pink Slips - again; nothing will prevent the slip being filled out
