I took the valve train parts to the machine shop yesterday. The "machinist" started on my head while I was there and used a large ballpeen hammer and what looked like a punch that fit through the center of the guide to hammer it into place. He complained that he did not have the correct diameter tool to fit the guides "but this one should work". It should have fit the hole exactly but it was a little too small. He seemed to have the correct diameter for all American cars and a few Jap cars, but not a 7mm. After some trouble getting the first guide in he said "I will have to freeze them first". He then put them in the refrigerator freezer and told me the head would be ready tomorrow. I looked at the one guide he did while he walked to the freezer and the top looked a little flattened where he had beat on it. I pushed one of the valves in and although it did still go in there was some initial resistance. I am also worried the seal will not fit properly now.
I am concerned that the brass guides will be deformed installing them in this manner. SHOULD THEY NOT BE PRESSED IN ?? Is it standard practice to install them this way IF one has the right tools?
He also said he did not have the right tool to surface the valve seats and that he would lap them in. That does not concern me as much as hand lapping probably does a better job if done correctly.
If the guides should be pressed in I would really like to know so I can say something before I pay.
Finding people to respect a VW is hard.
