Seriously, over 100psi at the head?! What oil are you running? Is it 90w140 gear oil ;)

Like i say i think that gauge got jacked earlier tonight when it got pegged so hard before teardown.  No way the head should be higher than the flange

Yeah I do believe pegging a mechanical guage severely does it in.

Blue paint, blue engine, blue interior too? ;)

Were you in Ontario today Dale? Swear I saw you in a crowd! lmao

In a crowd when all alone actually.  I get the best answers to my mumbled questions that way.  Spent the afternoon over the Rabbit engine re-installing the head and the header.  Under the car repairing the axle.  So NoPe, Notta in the White North.  Folks and some sibs live in MI but haven't been there in a couple of years. 

Does it help that Grandpa was French Canadian?  Got that universal face I guess.  And bald head

yup, its toast.. you over-pressurize them once, and they are never accurate again..

Turbo: exhaust gasses go into the turbocharger and spin it, witchcraft happens and you go faster.

Well, the orifices in the head are quite small. A higher head pressure could now be legitimate evidence of upper blockage.

However, I am truly "impressed" at your's and many of these new guys who dismiss clear evidence of problems (chips) with the ol' "I only need it to run a while longer......." thing. That mentality would be really "cool" if there was still a glut of these engines out there to be easily found. But, the fact of the matter is that these engines are getting quite difficult to find down here in the states. Especially the heads.

I'm sort of old-fashioned, but, I would have an honest interest in determining where the said chips are coming from. At a minimum, I would have pulled the camshaft to see what those journals are doing up there.

Somewhere, along the way, taking back-water, uneducated short-cuts has become rather popular on this forum.....always was over there on the "hillbilly forum." As for me...I was never impressed with the emergence of this "banjo-pick" mentality.

Good habits and smart decisions tend to be life-long endeavors. Good luck with your next "rebuild."

Ha! Please.. thanks for the post however...
Short cutting this motor was a calculated decision.  Ive been down the road of "should do this while its apart and should do that"...  following that metalilty theres no end until a full rebuild is done.   Fact of the matter is, on a high milage motor if you go look for stuff you will find it...
And doing it that way im stuck with a truck down i cant use, and back to driving my Mustang everywhere i go to the tune of a few thousand miles a month. 

Rebuilding a different motor does a few things
1) keeps the truck from being immobile in my shop taking space which can be used for other things.
2) gives me time to do it right and accept delays with parts and machine shop on the build motor.
3) i have a second caddy that was a diesel but someone swapped in a 2.0l 16v on rado digi 1.  I just gave that caddy to my girlfriend for Christmas.   Building a second motor for mine gives a donor motor for hers to convert it back to diesel.

Fact of the matter is, i would already be building the motor except over Thanksgiving i was tasked with redoing a civic for my niece to be done for Christmas .  Much dent repair, some rust repair,  some upgrades and a full respray.  Just getting the halfass headgasket job done was a feat with everything else happening.

So if in your eyes Im an idiot goon for limping an engine along until I can switch gears and begin a proper rebuild after Christmas and leave the truck running so i can haul parts in it rather than in the trunk of a 35k dollar car or in the bed of a 18mpg dually(parts houses and machine shops are all over 50 miles each way from here) so be it... 
I bought another motor from a dude in atlanta off the tex.. going to go pick it up in a week or so now that the caddy is together again.  The oil pump, glow plugs, headbolts i just bought can go in that motor.  It will get new pistons and a bore, crank cut if needed, head redone etc proper...  hope to have it all done by mid Feb.

Huh?  How so UNLESS there is pressure leaking from the chamber into the oil galley?
The filter flange is the closest port to the pump.  The pump will always have the highest pressure.  As you go away from the pump pressures in the galleys will always decrease due to numerous losses present.   Each elbow, each transition, each leakage path is a flow loss... unless something pressurizes the head the pressure at the head will always be lower...
Atleast thats what I got out of Fluid Mechanics and Thermo.  I hated those classes but did learn some stuff...

Yep.  Knowing the technical risks of your decisions is always a good starting point.  And at some point in time you graduate to managing the practicality of the technical risks and weighing with the other needs, pressures of life etc.
