I will post anything that happens, anything we find out, etc.

Yeah, I'm starting to think it's the rings as well, checked my dipstick a few times today, my oil is definitely sparkly, I don't know whether that is a normal amount for the break in of the old pushrods to the new rockers, and the rockers to the center pivot and valves, or if it's a bit to much for that. The oil seems slightly sparkly, in a microscopic way, with the occasional fleck that will catch the light, as pictured.

Color of oil:


Metal particle (circled):


More metal (circled):


not in my experience do they shed like that.. maybe find a cheap boroscope and take a look inside the valve covers and such (usually like 20-30 bucks) though a compression tester will tell you alot

Well update, talked with Jelly2m8, he talked me through some troubleshooting, which led us to believe that cylinder #5 simply wasn't getting fuel, and the tiny bit of oil leaking past the rings naturally was building up in the "dead" cylinder, and causing the fouling. I go out to my car to probe the injector connector, only to find that it was loosely sitting on the fuel injector, not plugged in at all, so I plugged that in, and bingo, power issue solved! All that's left is the metal in the oil, I'll change the oil and filter ASAP, and if there continues to be metal, then that's a problem I'll figure out, no more metal, then I should be good! I'll also do a compression test as soon as I can rent the tool, to just make sure of everything.

Nice!!!

Yeah, I didn't want to comment on the metal flakes... but in my experience that isn't totally unheard of when you have newer components. But I've not done this enough times to know if it's a good thing, or a bad thing. In my instances, it's always been when I install something brand new into an old motor... like the time I put a whole new set of flat-tappet lifters on an old camshaft. So my thought is that what you're seeing could just be all the new parts wearing in, which isn't a bad thing.

Yeah, we'll see after my oil change what's up with that haha!

Well, yesterday I found an oil filter that would work (grand prix filter, same connector, larger volume) did my oil change (took almost 5 quarts to fill till "full"), and drove it 80kms since then. Oil is still clear on the dipstick (can't read without a flashlight or angled to the sun), and I think what I was thinking was metallic "glitter" was not really, more the glossy oil combined with the textured paper towel, caught my phone's flashlight in a glittery way. New semi synthetic does the same thing, as does new conventional, so 99% of my "metal" was an optical illusion, although there were a few larger flakes before my oil change, specifically the 2 pictured above, which were not an optical illusion, but I am content with that, likely something to do with the new valve springs/valves/rockers/old pushrods combination.

No metal the new oil, with 400kms on it, still to clear to read the dipstick. I readjusted the timing to 13* or so, and got a 6.72 second 0-60, best before the 1.6 rockers and intake porting was 7.08 seconds. I'm quite happy with my rebuild (82 T/A, I'll have your money this Friday!)

Damn, that is an AWESOME time. This is with a 3.65:1 final drive 4-Speed? Man, that's fantastic.

What was the oil filter part number, if you don't mind?

Yes, the 3.65 4 speed, thanks haha, it's never had incredible synchros, so I may have beat on the shifts a little harder than I would have with a good shape transmission, but no grinding, nothing broken yet haha (when doing these runs with a regular shifter, I would occasionally grind 2nd/3rd, but I upgraded to the 84 shorter shifter and synchromesh fluid, and have had much fewer issues with my iffy synchros)!

The oil filter was Bosch 3430, for a 3.1l 93 Grand Prix, took 4.5-5 quarts to fill to full on dipstick (hard to tell with fresh oil)
