Jim,

I realize I'm probably in the wrong topic for this thread, but I found it using a search for DexCool and diesel engines.

Thank you for your reply. I've been debating making a routine out of re-torqueing the head bolts to make sure the proper pressure is applied to the head and sealing gaskets. I've run this by a few diesel mechanics and they emphatically say NO - DONT DO IT! If it ain't broke don't fix it, but I worry about the bolts stretching.....and it does have a turbo.

The problem I face right now is if a head gasket does let loose I don't have the injector height tool used to set the injectors. I've searched the internet and old diesel shops but can't locate one. Once a head gasket is replaced the injectors need to be re-set and that can't be done without the height setting tool.

I've not been able to get anything back from Detroit, but I'm still working on finding an engineer who worked on the design and support for this engine.

Thanks again,
