After reading about an Alpine Coach burning down a few months ago we decided to stop in Hemet, Ca. area and get the manifold replaced and take care of a few other things that had been put off.
I posted on another forum about some of the failures and will continue to post pictures of the repairs.
I have heard from different mechanics over the years about heat issues from the exhaust brake being mounted in so close to the exhaust manifold as being the culprit behind the cracked manifold. Anyone else on this forum had the problem?
The turbo lube oil supply line is within a few inches of the cracked manifold and that has the potential for major problems in my mind.
