Yesterday I decided to get back out in the garage and get more of the 2.0L type 4 VW engine put together. I grabbed the heads and the cylinders and got into lapping the cylinders into the heads. I soon found out that the heads were causing a problem. I had the heads done at DRD and they had come back with more problems than I have ever had with a set of heads before. NOW, I find another problem. When they had opened the chamber in the 1.7L heads to accept the 94mm cylinders, they had cut too deep.
They had cut down .285", which is a problem, because the cylinder shoulder is set at .250".
I brought the heads into work today and ended up cutting the head down .045". Now I have a clearance of .010" between the head and the cylinder body.
I lapped the heads, which took a while, installed the cylinders/pistons, and then installed the heads.
I think I will leave it at that for the night. Tomorrow I will install the valve train, pushrods, and tubes. Then I will sit down and figure out my oil pump situation.
