GTR R-32 smoke after dyno

[Tardo]

Missing under load, white smoke, stops missing when warmer, still residual smoke! This started about 100klms after a dynotune.

I don't really want to fork out another $1200 until I have a rough idea what the problem may be. Any ideas?

Car has a Haltech Platinum Pro ECU and a single Garrett 3076R turbo.

Kinda sounds like a head gasket.

What color is the smoke?

[Tardo]

White smoke or vapour, not thick!

[Ben C34]

That's not going to tune out mate. Start pulling the head off, or if you want to confirm first do one of those tests for a popped head gasket.

Sucks to hear mate, but yeah - I'd be investigating the head gasket  

[JamesStojcevski]

Shit go man! Sounds like a head job these guys here are onto something

[Tardo]

Sigh!! I'll do a test first.

Hey guys, amazing what a bit of investigating can do. Found a corroded and leaking coolant pipe under the intake manifold, which probably explains the white vapour/smoke. The missing under load was caused by a cracked spark plug on number 4 cylinder. I thought a head gasket issue was unlikely cos they're pretty bullet proof on the 32, so glad I didn't rip into it!

That’s great news.  Pretty amazing two issues at same time made it seem like something else!

Good result. If you are replacing pipes under the intake manifold, do them all in one go. Kudos Motorsport sell a kit. I even ordered OEM hard lines and replaced them while at it and the parts that plug into the block. And to add, knowing corrosion has started on that side in the coolant pipes, the turbo side will only be a few months away from doing the same so if you are going motor out I'd go to braided lines on that side too. 

Also where do I find one of these bullet proof head gaskets?.. haha.
