Got the mill out, what concerns me that there's cavitation in the timing cover, not sure if it was there or what the FAK, I'll have to go back thru this thread just to makes sure it was or wasn't there when I installed the engine back then.
Damg, is that from the coolant? I know they say we need sca in our coolant. Or maybe its no sca 🤔
I'm was running ELC (red) with distilled water i have no clue why it turned like that, coolant passages are nit rusted at all only the timing cover, wich was painted when I rebuild the engin, Im assuming the old paint fell off and that's what the timing cover looked like before can't remember though, but that cavitation might of not been there or it might of.
Couldn't find a better Pic of the timing cover, as I have already painted it, but did go back thru the my thread and found this Pic which looks like it already had some cavitation on it as it's missing some material from that area I believe.
Amid looking closely at the Pic you can see some of the rust showing a bit on the right side of the timing cover port.
no rust in engine block so I'm going to assume the timing cover had rust when I painted it.
I have a spare that's in good condition from my 00.
now to order the front timing gaskets
Well found the culprit for the coolant leak but also found a bigger problem that was a kick in the nads.
Simple fix, but then I remembered that I had some blow by fumes that were a bit concerning on cylinder #3 so I removed the head and found the piston had some circular movement, so turn engine over to TDC on all cylinders only to find cylinder #1 had some ware grooves from the wrist pin making contact. So off to the machine shop to have it sleeved and replaced those two pistons, wrist pins and maybe even the rods if they got damaged.
And when I removed the oil pan I found 3 wrist pin retaining clips tucked into the oil pick up tube. To be fair I did abuse this engine alot not by neglect of lack of maintance but for having a very heavy foot so it's my fault.
Cross hatching on all cylinder looked great, only cylinder 1 that I can see is the problem.
My dad and I run Rotella ELC red too. Both trucks are coolant filtered. I got my trans out again, doing all kinds of goodies while it's out. Gonna finally start on it next weekend hopefully.
Any idea why the wrist pin is contacting the cylinder wall?
Maybe I'm blind, but is the tinibg cover issue due to a missing dowel pin?
Can't remember your engines year, but the pickup changed in 97 from driver to pass side. So if you swap timing covers, make sire the pickup will work, too.

Broken retaining clips allowing the wrist pin to walk.

The timing cover had cavitation on that water passage which looks like it was missing material st the ttime or maybe it was little material left which at the time I didn't see a "problem" with the timing cover.

Engine is from a 00, asbwell as everything attached to it minus engine wire harness and WIF sensor, rest of the sensors are SD which work with the OBS PCM.
Well more ****ty news, one of the cam lobes is trashed as well as the lifter that took it out, funny thing is the truck ran great with no obvious noises.
So I will need two new pistons (other 6 psitons look brand new) sleeve those two damaged cylinders which I might not do, due to cost, and just take my other spare short block for work and re use the cam that's on that engine.
Well crap man, this sure all sucks. I wish I had any parts to send to help. All I have are 7 std pistons since my "to be built" core needs bored.
I hope you get it fixed soon
The mule needs to be driven!
Thanks for the offer man. I have all parts needed. And yes I miss driving the old beast, I won't be pushing this new mill hard like old one, costly lesson learned, but I'll admit it was fun while it lasted though lol.
