Steve, Without looking at the photos, I have never heard of a multi-layer gasket being reusable. The purpose of a multi layer gasket is to provide a greater degree of conformability into any undulations that may be present. Most gaskets would have a wrapped bead around the bore orifice to fulfil exactly this requirement. If your current gasket does not then you might be as well off getting a proprietary gasket for an RS Turbo engine and rebuilding your current engine yet again.
The only type that I would have trusted in this application is a single layer steel gasket used where high cylinder pressures are expected such as on highly boosted diesels (= >2 bar boost). Such gaskets demand a much more accurate "level of flatness" for want of a better term as they do not confirm to irregularities to the same extent.

I've also got a bad feeling that as this is the second time it's done this between the same 2 cylinders that head is probably scrap. I have managed to buy a full FRST engine, which is believed to have knackered big ends, although it turns over freely enough. However, more importantly the head gasket is claimed to be a multi-layered reusable gasket and the head bolts ARP non-stretch. I've stripped the head down and below are some links to photos - I'm showing the standard head gasket as well, including a close up of where it has burnt through - I expect that the gasket on the car is exactly the same. Could I just bolt this head on using the multi-layered gasket and the ARP bolts? Do the non-stretch bolts need to be torqued up differently? or to a different torque? http://www.h4-turbo.co.uk/img/StandardHeadGasketFull.jpg http://www.h4-turbo.co.uk/img/StandardHeadGasketCloseUp.jpg http://www.h4-turbo.co.uk/img/StandardHeadGasketCloseUpDamage.jpg http://www.h4-turbo.co.uk/img/MetalHeadGasketFull.jpg http://www.h4-turbo.co.uk/img/MetalHeadGasketFullCloseUp.jpg http://www.h4-turbo.co.uk/img/MetalHeadGasketCloseUpLayers.jpg http://www.h4-turbo.co.uk/img/MetalHeadGasketCloseUpLayers2.jpg http://www.h4-turbo.co.uk/img/HeadBoltsFull.jpg http://www.h4-turbo.co.uk/img/HeadBoltsHeads.jpg Regards, Steve -- www.h4-turbo.co.uk --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
