I have a 1984 F350 Dually with a STOUT 460. You can have the truck for cheaper than whatever you need to do to the Sub..... Just sayin!

I found a local reputable diesel place today. They were a 45 year, family owned GMC truck dealer until the 2008 GM slaughter of small dealers. They are still a GMC truck repair facility for light and med duty trucks and familiar with the 6.5s.

That being said, I pulled the drain plug and there was a lot of coolant at the bottom, under the oil. So it is looking to be a bit more serious than a head gasket, possibly a cracked block or head. And if the coolant ran through the bearings for any length of time, that pretty much points me towards a new engine.

The shop is going to do a compression test and dye test next week to confirm a diagnosis and see exactly where the failure point is. We will then make a decision based on the facts.

Anyone have any experience with the GM part # 88894125, which is the brand new factory long block? They go for around $6K and have a 3 year/100K mile warranty. I am looking for warranty coverage otherwise I'd go with a military takeout. The shop said they have had nothing but trouble with Jasper - he said they had to replace a Jasper Duramax three times on the same job. After that they wouldn't touch a Jasper again

I can't imagine the engine ran long if at all with the coolant in it. I say that because you checked the oil after you shut the engine off and it was normal. Then you checked it after it sat and it was high. Also, if the engine ran with the coolant in the oil, it would be milky, not separated. Why are you thinking it is something more serious than a headgasket at this point?

Like Oscar the Grouch, I am an eternal pessimist. That way if something goes right, I can only be disappointed by the fortuitous results. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img]

I'd just slap a junkyard motor in it.I mean one that I could hear run.

They are out there for cheap.

I checked into the Cummins update. Too much labor and modifications needed, like a mandatory 3" body lift it to clear the oil pan, rewiring the truck, computers, etc.

Oh, and I nearly forgot to mention...all said and done, the conversion is almost double the price of a brand new 6.5 Am General 6.5 (GM actually sells the AmGen updated 6.5 that are used in Humvees as their replacement crate engine.) The crate engine dealer that was at MCACN ran my VIN and got me the proper part number for the new longblock assembly, and they seem to be available for around $6,300.

As for junkyard engines, not even the rebuilders use the cores any more because 90% of them have internal stress cracks in the heads and main webs. That is why AM Gen reverse engineered the block and made their own version.

You were told correct. No junkyard 6.5's....
