Today I rechecked this engine
because I wanted to take a picture of a part for Mrvos.
I also took off the storage cover to see `how it was doing`. I regularly do that. I add some motor oil on top of the pistons and turn the motor over a few times by the crankshaft, both directions, just to make sure it all moves inside for a few revolutions and oil relubricates the parts better than standing too long unmoved. (I`m not too happy about the c
ooling system `new` surface rust but that can be cured later on AND I`d like to ask questions relating how that`s done most efficiently)
About a year ago I didn`t go back to continue working on this engine because somehow I got busy then I got confused...
I thought, until now, that
this was the d24 where cyl#1 had a bad head bolt thread discovered.
I checked my notes I wrote when the head came off. It was
not this engine but
another d24 I have. That day two d24s got their head off so somehow I mixed the info up.
This is some good news because it means that this d24 can have the cylinder head back on and get back to running condition relatively easily one day (easier without, than with fixing damaged headbolt threads).
The cylinder head of this 1984 d24 shows cracks between the valves and I need to check that for sure. If it isn`t too much out of the specs and if it isnt right near the waterways then that`d be good enough news for me to proceed.
I`ll get it out of storage and reinspect. I have the Volvo tools to measure it and... fingers crossed.
For now I filled the headbolt holes with diesel fuel and rolled the engine over plenty of times. I added a spoon worth of diesel on top of the pistons when I did that. It all moves freely and nice. I soaked some paper in diesel and covered the head with that and repacked it temporarily. Let the thing soak a little, hopefully it will be much easier to achieve getting the surface cleaned up better or easier. What an ape method there
I really need to get this back together.
Here`s a link to the video how it ran 4-5y ago when I took it home and set some things up to get it started again:

Here`s another one where it runs well, it`s a coldstart BTW (well, in June, but engine was cold). It had some blowby but not very bad. Valves set, new plugs, manifolds off for new gaskets, intake cleaned, new oil new filters, pump removed & flushed then reinstalled & timed etc basic stuff, new oil pan gasket, orings at various places, new tstat, v.c gasket etc

The problem was that when warmed up, this engine would pump some exhaust gases into the coolant reservoir tank. I ran this for a few times dry without noticing... I only got to know about it after I set up a completed cooling system for this engine. I bled all air out but started seeing `air` again which was not air but exhaust gases. So that`s why after taking some videos of it running, the head had to come off and get inspected anyway. Well, that project really got `stuck` back then.
Soon, a project may restart to get it fixed up.
All accessories and parts have been removed and properly packed away and kept in dry storage, sealed up; so now it all depends on what condition the cyl head is in.
Here are the photos from today:
