I received a set of copper gaskets with my new AA P&C's and I assumed they go between the heads and cylinders (they fit perfectly inside the heads around the valves) but after I torque up the heads there looks like there is a space between the head and cylinder the same thickness as the copper washer - did I put those in the wrong place?
I watcehd Jake's video and he mentions nothing about a gasket here? |

Step away from the head gaskets! Don't use them. Hate them. It doubles the oppurtunity for a leak. Instead of one interface, you have two. VW issued a bulletin years ago saying not to use them. Make sure you have .035"-.040" deck ht in the cylinders as the head gasket adds to the deck. When you pull out the gaskets you drop the deck ht. Generally the gasket thickness is around .028". Vance are the heads the ones I did for you recently? If so lapping will not be required. If you do lap use a compound of Ajax or some other fine abrasive cleaner. DOn't use the valve grinding compound you get at NAPA or other parts stores. It's way to abrasive. Spin each cylinder the same amount. Lapping is more of a QC proceedure than anything. You just want to make sure you have contact all the way around. Marking the jugs and the heads with a Sharpie helps identify low spots. Do you use any type of compound between the cyl. and head for assembly? |
