Your best option is to do the head gaskets and have the heads checked, install studs on the block, and get back on the road.Another one for the chalkboard guys. My head gasket is blown. I had it towed to diesel repair. They have condemned the head gasket after compression test. After sensing the loss of compression the hours I was messing with it, I believe them.
Options.. Whats the best reman source these days?, I'm hoping I can afford a reasonable long block assembly and have the shop swap it in without going bankrupt..
Salvage yard assemblies run about 1000 bucks but I don't feel good about that idea.
Remans are sketchy at best.
Avoid US Engine productions advertisements for low priced reman options.
There are a lot of China Knock off and Brazil blocks out there waiting to give you grief if you're not careful.
There used to be viable options for military take outs but those sources have dried up..
If you go with a new engine expect to pay around $8k
The only ones I would recommend for new.. would be Kennedy Diesel or Leroy Diesel
