That was a great story - I got the visual on that - can totally see that happening. Usually that *censored* happens to me! Sometimes I feel like my life is a movie.
Welp, I've got the engine in the barn all covered in a bed sheet, to keep the dust off it the Marquis kicks up every time it comes in the garage. Everything in there has a layer of the *censored* on it. Definitely NOT the place to be doing precision engine work, but until that future lotto tic pays off, it is what it is. I won't hold my breath ...
Definitely not having fun here. Not making any money working on my own *censored*, which sucks. I could've had that Focus cleaned up and probably sold by now ... but here I am. Just want this engine to last a few hundred thou longer than it was designed to.
Anyway, flipped the engine upside down on the stand & got in there with a flashlight. All the cylinders still have most of the crosshatch left in them ... slightly glazed, but the undersides of the pistons were REAL clean - not what I was expecting. Could see most of the cam from there as well - nothing that jumped out at me there. Looks good. Turning the engine over by hand told me all I need to know about the internals - this engine is solid - I'm not gonna screw with any part of it, except the oil pump, screen, timing chain, & head gaskets. Even turning it slow by hand the piston rings had very slow leakdown, and each one sounded & felt the same. Lots of compression resistance. Should've done a REAL compression/leakdown test on it, but I was so pissed that I had to yank the engine again ... that was the last thing on my mind. The thing runs strong - REAL strong for a 6, so I don't much care about the numbers. Oil pressure was always good hot - much higher than the old engine using the exact same gauge & sending unit.
Being that this engine spent 80% of it's life in a rental vehicle, I have to say that this could be engine #2 for the Jimmy in it's lifetime - it was just much nicer looking in there than I expected - definitely doesn't look like a high mile engine based on past experience. Very simple design - identical to a 350, minus the 2 cylinders in front, and with a goofy offset crankshaft, & a counterbalancer in the lifter galley.
Only bad things I found were LOTS of slop in the timing chain - about a 1/2" (!!), and a thick layer of sludge at the bottom of the oil pan. Judging from the condition of the cooling system when I bought the Jimmy with 106k on the clock, that was probably from the same lack of maintenance with the engine oil. Luckily that person didn't own it very long. She was the first private, non-rental owner, and had a lien on it. Was very apparent that maintenance was not her forte. It then went to auction, and was bought by a dealer in GA that I bought it from. They detailed the hell out of it - made it look showroom mint ... and even though I know better, I fell for it. But this engine is much happier sans all the unreliable resistors, capacitors, chips, & circuits it once had.
Spent nearly it's entire life in FL & GA, and the pistons had no signs of scorching on the undersides. That was surprising to me. Even the Focus had charred, black deposits under each piston. But that's the main reason I want to change every gasket. Southern states are very tough on rubber & plastic products. Just the fact that it didn't leak everything everywhere tells me this engine's been freshened up or replaced once before.
I'm just going to order up the aforementioned parts, along with the gaskets - all of them, and maybe a set of brass freeze plugs, and call it a day. Now I get to do the barn roof while I wait for parts. Of course, guess what the forecast looks like?
