Back from the mechanics. That awkward bit where he gets to discover you've been having your nuts turned by a stranger.
Head gasket leak a 99% possibility after eliminating anything cheap.
So.. It's apart. Actually should be bolted together by now. Slow week.
Wherin two mechanics call each other incompetent over each other's work
I seem to recall the other guy didn't think much of my regular mechanic's approach of using just the materials recommended by the manufacturer.
By the way, that guy : not in business anymore. Not that I can find. So, tail between my legs, I go back to my old reliable. (he's 70, so I better get what I can)
He didn't care too much for that the guy gasketed every surface he could get to, on a engine designed to be put together with seals, bolts and gaskets that don't come out of a tube. Except in certain places that somebody who does these motors all the time knows to do, If they don't want to put up with you for awhile.
And I didn't much care for having a head, rebuilt with new valves, planed etc and then have a big CLUNK-bonk on the surface that led to gasket failure.
50,000 miles later give or take a city block.
Ah well.
If you're going to screw it up, do it yourself. If you don't want to screw it up, get somebody with experience with your type motor. What remains is what I did. And, overall, it was a good job except for the part that made the whole process moot.
No use tracking that guy down, at 50,000 I think the guarantee has lapsed. Maybe just an anonymous copy of the pictures with "Watch it next time."
With another copy, for me, taped to the inside of the hood.

There is a time and place for sealants. I always cringe seeing gobs of sealant coming out of places where there is supposed to be an o-ring seal or a gasket seal.

Yes. Different surfaces, different needs. Some things designed for it, others, not so much. What works for a car will destroy a pinball machine. Wait, that's WD-40.
But I'll order the O-ring from Germany or Japan or wherever before I'd substitute a chunk of sealant.
They put sealant on top of the flange o-rings. I guess that makes sense. Just tighten that plastic flange a bit more to compensate.
And, let's be honest here, it didn't leak except for one specific place.

Simple things can cause major problems when dealing with sealed surfaces. Clean, clean, clean is so important when dealing with engine assembly.

Yes, clean. It was clean, once.
Factory service manual. Wouldn't drive around without one.

I almost always use some RTV on the coolant flange gaskets on my car. Craptastic aftermarket seals seem to be thinner and don't seal nearly as well, plus the craptastic aftermarket plastic flanges warp...

As a former employee of a craptastic aftermarket auto parts supplier..
no, avoid craptastic. Avoid avoid avoid. Unless you can fix the flaw or it's something that genuinely is just the OEM's former manufacturer. .
Some things are so complex that nobody makes a cheap copy.
They used to call them counterfeit parts..
I've found the same exact component and supplier (eventually you figure out what the real OEM supplier is/was) ranging from $27 to $150.
I guess it helps that I'm right at that point in the car's life-cycle (1990) that more places are clearing out dusty warehouse queens than others are calling them vintage NOS.
Sorry folks, eventually I'll get tired of wrenching my DD. Something from this century, perhaps. Then I can wrench the EODDs.

I've found the exact same oil cooler hose ranging from $35 to $100, lol. Ridiculous.

Was the head milled by a competent machine shop? If not, then you're setting yourself up for another eventual failure...

There had been a bit of discussion on that. Guy feels the gasket will do, and that the other guy's coating of the surfaces helped make the problem worse somehow. Did check for warpage, etc.
Good point, though. It smoothed out pretty good, there is now no metal sticking up, anyway. Down, not so much. But this is a vehicle of diminishing returns, and believe me, I know how to kill one of these with heat. So I apply a less extreme approach and it should be okay. I know where it will go.
But yes..
There will always be that little bit there just waiting.
