Klaus,

Well I finally pulled the head tonight and I believe the issue with the compression is a combination of two things:

1. Failed head gasket on both exhaust side corners on the side that sits on the block side (I've taken a picture of this to show. Will post once the job is done),
2. Potentially bolting down the bolts to tight on the outside vs. the inside as you mentioned in your post.

With this head install I've also purchased a Volvo head gasket as the last one was an after market. Hopefully this will make a difference once I'm done.

Once done I'm still going to have to do all the engine mounts as I've determined that they are shot, especially the one on the passengers side. Really Shot.

Will post pictures once the job is complete. Also plan to retest the compression once done and see where I now am. Should be done sometime tomorrow afternoon.

Talk to you later,

Matt
