Some before and after numbers from the recent rebuild. The April 2023 data is from the oil that was in the truck when I bought it. This resulted in a full engine tear down to establish the extent of the damage. Fortunately there was no sign of any wear with the sole exception of the oil pump bush which was replaced thanks to @landtank . The timing chain and slippers were replaced as a matter of course but I didn't (not sure why) change out the sprockets. I suspect the iron in the sample is the new chain getting to know the old sprockets. The next sample will confirm this either way.
The truck only made it out of the garage in December. The first oil change was at 600 miles and discarded. The second oil change was at 1200 miles from which this sample is based. Lots of help from @BILT4ME during this rebuild for which I am extremely grateful.

When I bought it, it had a blown head gasket with stop leak in it. Head gasket changed and head decked, ARP headstuds from 2JZ, a few valves shimmed, timing components changed because the tensioners were broken, new oil pump cover, front and rear main seals. Really just about every seal. Hoses etc. At this point the only leak on the engine is a tiny leak from the power steering pump.
It was getting a lean run CEL for the first 2-4k miles after it was all put back together and ran probably 4-5 bottle of Redline SL-1 over the course of that time. But changing the O2 sensors fixed the CEL. I did the short interval at the request of Blackstone, and I've since pushed to 3000 then 4500 mile intervals. I belive the coolant was just some residual from before the work was completed since it doesn't seem to be present now. I skipped it on this last oil change, but I'll probably do it again on the next one just for my own piece of mind. I also changed oil brand and weight on this last oil change. Something a little heavier 15w/40 conventional. The vehicle performs well and I get 14mpg consistent with 35s and just a TCase high range regear.

Here is the next report. I'm very encouraged by this. Guess the engine rebuild/replace gets put off for now...
First sample back for the 1995 w/Supercharger. No idea how long the oil was in the engine but what I do know is that I drove 1100 miles back home when I bought it. Looks like I have a solid base to work with so happy days

That's great news, which I bet you expected. That cruiser was and will continue to be well taken care of. I am considering getting an oil analysis on my late friend's 80 that I drove up from FL to TN (700 Miles/10 hours). I expect the analysis to show excessive amounts of wear metals, indicating a bottom end on its way out. I'm curious!First sample back for the 1995 w/Supercharger.

It's definitely worth it for the peace of mind of just knowing. I'd rather know even if its bad news.

Head gasket was replaced at 238,500 and the first test after that seemed to still have signs of coolant. Probably was residual in nature as this one has me breathing easier

Here is my second BS after new short block. I have 215k+ on her now…

Here’s the report I’ve been waiting on from Blackstone. It is for the new ‘93 I just picked up. My buddy owned it before me and mentioned it had a knock. I noticed it was intermittent, loud(especially on cold start), and abnormal. I'm wondering if it's the oil pump gear. For now, I’ll be baselining and driving this cruiser.
