Missed the GTG but.
My weekends have been taken up with if you can believe it helping a pal rebuild a 6.5 turbo diesel, just a tiny bit different than a Gasser engine.
It had a valve that had pieces break off that fell into the combustion chamber and inbed into the top of the piston.
The heads were cracked a bit so buddy decided he wanted to do all the cylinder rings and get new heads, so that's what we're doing.
Interesting though he priced out a bare head from a GM dealership $2,600.00 each.
Went to the local engine machine shop got new head with new exhaust valves and all new guides and pre chambers all machining and installation so a completely dressed head for $503.00.
Does anyone wonder why the dealerships have such a bad name?
Back at er today.
