Anybody ever tried something like this to convert the 2.5L NA engien block from an open deck to a closed deck?

Looks very interesting. Did you read the entire thread? If not, go to the end & work back. :wink:

OK -I read the thread up to about page 20 where ccfab indicated the sleeves had a bunch or hairline cracks on the outer portion. It was getting to be too much of a soap opera after that. In the posts, it seems the general consensus of the failure was different rates of expansion between the aluminum and the devcon.

Oh well, I thought I had stumbled on to a way to address the head general gasket issues seen on the 2.5L NA motors. I was thinking if it worked well on a turbo motor, it would work great on a NA motor.

When I was much younger, I worked on VW engines. Now, I'll leave the "internal" work for a shop that has the facility, tools & expertise to give me the end results I'm looking for. :wink:

Still... the process the builder was using was interesting...
