Heat cycling hardens and shrinks the original rubber and paper, and seeping valve covers, oil pans, turbo mounts, up-pipes and coolers are the result. Fresh OE-spec gaskets and seals restore a clean, leak-free seal during any service or reseal, so the repair holds up and you are not chasing the same leak again.\u003c\/p\u003e\u003ch4\u003eWhat's Included\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ethe gaskets and seals needed for the repair\u003c\/li\u003e\n\u003cli\u003evalve cover, oil pan, turbo, up-pipe, EGR or oil-cooler sealing parts as applicable\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eFitment\u003c\/h4\u003e\u003cp\u003eFits Volkswagen, Audi vehicles equipped with the 1.9L TDI diesel engine, 1999-2006.
