Gasket leaking?

[knore]

Had the safc2 and sitc tuned today on the dyno, it made good power, 189.9kw on 10psi. No pinging or knocking during the tuning was detected.

But straight after driving it i notice it sounds a little weird and idle is alot lumpier than before, it drives fine, no problems with power but taking off is a little jumpy

could this be a blown or on its way exhaust or head gasket?

ide be guessing exhaust gasket as i can kinda smell exhaust and when i put my head near the dump pipe/turbo, the engine sounds a bit strange, especially when revving it lightly.

How do i know if its this for sure?

Anyone else has this problem? And whats a new xzorst gasket worth?

cheers

Anyone?

I had a good look today and im 99% sure its the gasket thats farked, its split in the bits between the manifold runners and there is some oil vapour around and on the split gasket bits.

I know changing exhaust manifold to block gasket is a bitch, but whats the cost of getting it done and how much is the gasket itself?

The manifold bolts onto the head, not the block. About $50 for the gasket and a large amount of work, so expensive.

I'm not really sure from your description that that is the problem though. Can't be more specific though sorry.

would cost around 150 bux for the top gasket kit.. and probably around 4-6 hours labor @ 55-5 bux... big money.. I know cause i have to do this to my line. but i get all the labour for free so eh cant complain.. 150 bux isnt bad for more boost

Yeah sometims the tracktor sound indicates a blown exhaust gasket.

You say it is in peices/falling to bits.

ok, found a wire loose going into coil pack 1, thus explains the lumpy idle and shaking

noise is still 99% sure exhaust gasket, its fairly audible just above the dump pipe, is only there on idle and light throttle

guess ill be pulling half the engine apart to change it
