Otherwise yer right, blown HG wont generally wont compress into oil and coolant galleries - but oil and coolant WILL seep into combustion chambers. Seen this myself with M180 inline 6. Meanwhile coolant bein more pressurized than oil fills the sump through entering oil passages and provides false readings on stick as if oil level aint dropping.
gdemoss tell us the truth, what exactly are you workin with here? Was the engine run outa oil and/or driven how long with blown headgasket? Gotta pull the head to inspect bores first thing. What the hell are you waitin for? Pulling cyl head on 616 is easy. Skip the compression test says me.
Meanwhile diesels do NOT rebuild easy. 22:1 compression ratio with 350 lbs per jug you understand. Backyard build might last 60k miles if engine's been severely abused. Personally, I will never buy an MB diesel where seller boasts of "rebuilt" engine. Gimme an original decent running Stuttgart engine and i dont care how many miles it's got.

I can't be positive it has a blown head gasket. When I bought the car it started and ran but used mucho oil: 1qt/350 miles. I'm basing the blown head gasket on speculation (said mechanically challenged) because there is a large amount of oil that is visible, caked on , on the intake side of the engine. It looks like oil just seeped down the side of the engine for a long time and dirt caked onto it.
The vehicle in the meantime has had a completely rebuilt engine put into it and runs perfect (after many travails).
So, I've got another 300SD with low compression that I hate to give up on but probably needs an engine transplant. So, I'm just playing with the idea of putting rings, etc in the engine out of the other car a swapping it with the one currently in the 300SD.
Just trying different scenarios to determine easiest, simplest, and least expensive.
Thanks.
