XS power parts - another warning

I'd been silly enough to use an XS power T4 gasket and oil drain gasket on my T67 conversion. The results are pictured here after about 5k miles of usage (very little of it being on-boost).

The T4 gasket had completely disintegrated on one corner, the sandwich layer had burnt away and much of the steel plate blown out into the engine bay.

The oil gasket had gone brittle and cracked resulted in a small leak.

Replaced this weekend with qaulity parts and the car is running perfect again. Just another warning to stay away from cheap/copy parts folks.

The turbo is thankfully undamaged, in fact the exducer and compressor blades look like new

So thats just about everything they make ticked off the list.

All them gaskets are crap no matter who makes them, i had loads of trouble with mine, after speaking with Leon at JPS he told me he never uses them for his very reason and just has both faces machined for a perfect fit and not to use a gasket, i did this and no more removing turbo:)

Thats pretty much what I've been told since Darren brought this up. Either a sheet SS gasket or use none at all. Either way, it's in the XS "kit", so if they're not suitable they shouldn't supply them. Same as the fuel hoses, vacuum lines, FPR's, adaptors, turbos, oil feed, oil drain... pretty much everything they supply

I have seen several new xs manifolds flanges to be warped. even when new so unless machined flat they will never seal 100% or gaskets last very long.

Yes i would say check you mating surfaces for trueness, even top notch gaskets will not last long.

Embossed stainless steel shim gaskets for turbo to manifold and WG to manifold is the only way, but if flanges distort any gasket will fail.

Good point, is the flange on the XS Shower manifolds thinner section than other 'quality' manifolds?

lesson learned for everyone eh? xs power gettin such a bad rating on here, any of their stuff actually good??

i would expect any flange to have a degree of warp after welding, i guess the quality brands would machine it true as the final task, you get what you pay for

After seeing one of there manifolds i wouldnt buy anything with their name on it.

I have a XS exhaust and it is good quality. good welds etc, but some of the stuff marketed under the XS banner is produced and made by other companies.

When i fiited the xs manifold the T4 flange was warped had to have it machined, also you will find that the flange from tubes to head is not also true but slightly warped which also requires some machine work. and once all the weld slag is cleaned up from the inside its not that bad of a manifold:innocent:
