Default Pictures and facts.

I could not find the straight edge to measure cylinder head warpage but the Volvo tool with the dial gauge gave me a good idea about it.
Let's see how the gasket looked.
Ngoma, i tried removing 2 of the headbolts without the suggested punch and yes it seemed much harder that way. Thanks. Good tactics info for the future...On this engine it doesnt matter though...
The gasket is a GOETZE headgasket. That rubber triangle area looked bad and you can see lots of rust at the headbolts (i think they are the result of the punch on the headbolts.

Also, one of the headbolts on cylinder #1 (front of engine) was LOOSE. I think the front of the engine is where the head will be warped the most.
The camshaft has rust and is pitted and scarred like there was water in oil, or like there was thick "sandy" oil used lmao.
Plenty of the valve shims were deeply pitted and chipped a little. I recall doing the valves adjustment appr 2y ago where all* clearances were tight and out of specifications, intake and exhaust included. Also a waterpump with the wrong-quality impeller.

More than one of engine oil passages of the head had 50% of the inner diameter clogged up.

Surface rust existed inside the engine too.
Camshaft bearing surfaces have wear marks too.
A couple of cylinder walls have vertical marks too, ,
Surface rust PLUS there are signs of valve collision with the pistons at more than one cylinder.

At cyl one, I have to check if threads in the block still exist at all.
Also, the cyl head has broken-in bolts at ps pump bracket and there is one where the balancer connects to the engine.
The inj pump pulley has a chipped area too like someone was having it beaten up. Lol.
The front tb area is very rusted too, including the waterpump and thermostat areas where the coolant runs.
I remember doing the belts on it and getting freaked howmuch internal rust it had.

Well, that is exactly why it became the "experimental engine" to learn "the d24 stuff" on.
Many days spent thinking and doing and a lot learnt.

Now I'd say it continues staying the engine for "d24 exercise"
The parts that it donated will make a good deal for my other d24 that also has issues although much less and it does run. But I assume it needs a head gasket. I saw bubbles form in the expansion tank when i ran it for like 45minutes the last time. (1984 engine, nonturbo)

So here's a few pictures.
I hope they serve the volvo diesel community. And also wondering how (if) a chipped injector hole gets fixed. (For those who happen to end up unfortunate on their great condition engine)
