Piston/head #3&4 revisited:
After some wire wool this is how the pistons look like after cleaning up:
On both pics you can see where the intake valve nicked the piston head, but is very clear in the second pic. No doubt that the deck high is way off. The "pro" that did the fly cutting on the heads cut them too deep...
Yikes! I am sure I put the rings on the right way..., or did I?
Well, I will be pulling the sleeves off at some point now too! As to the case, I will verify the code tomorrow. This should be a stock Vanagon case. I did not mention it the first time round I think.
