Is there oil seeping between the block and head by the timing chain tensioner and #1 exhaust runner? If not, I’d put off replacing the head gasket.
One school of thought is EGR soot deposits on the exhaust valves and pistons causing the rods to bend. I’d do what I can to [ahem] prevent that.
Tom, I think he means he’s ready to swap a 3.0 block under the 3.5 head if he finds the rods are bent.

AFAIK the whole block, head, hg is dry on the turbo/exhaust side.
Only notice oil at the forward-most intake runner, seemingly due to bad intake gasket. There is zero blowby smoke even when full hot after a highway run. But the think I’ve noticed is some black oil sheen in the plastic coolant tank. I verified the coolant in the system is a beautiful clear blue. But I suspect there is some seepage some place, under some conditions.
I have ordered the intake gaskets and look forward to cleaning the whole thing off and out. I remember doing that on my father’s NA 606 after around 150k and getting a decent amount of junk out.
I do want to check out the turbo, both boost levels and oil in there, but it’s much more complex to get to than my 617 (initial impression, maybe I’m wrong.
EGR got a ball bearing in the hose as soon as I took possession. Should block vac decently, it was a big ball and firmly planted against the EGR nipple. I get it that they can be stuck open. Priorities first.
