Welp, it had to happen sooner or later. The Regal isn't doing so well, knocking on heavens door, if you'll pardon my pun. Happened this morning. Started pinging really bad, or at least breaking up during a gentle acceleration and I punched it thinking it was just something in the carb sticking. It cleared the problem up, but a few minutes later knockknockknockknockknockknockknockknock. This motor has survived being boiled alive three times, frozen almost solid once, and more revs to 5500 and beyond than any BOP motor should ever see. Oh, and I broke in the motor with no oil pressure. That'd do it too I suppose. Plenty of flow, no pressure behind it. It lasted a tick over 5600 miles, through two transmissions, and countless peg leg burnouts and donuts. I salute you Buick, you shall surely be missed in these coming months until I can foot the $1,500 repair bill. Gonna have to get the crank turned on the rods n mains, rods resized and new rod bolts, and the whole shebang balanced with the balancer, flexplate, rods, and crank. Shop quoted me about 600 bucks, and I estimate I'm gonna need gasket set (duh), maybe new pistons if it was detonating as hard as I think it was (plus 8:1 is no fun without boost), the rod bolts, a new flex plate to replace the original one from 1976, and have the cracks in the manifolds welded up, which I can probably have a buddy do for free, and maybe a new cam if mine looks suspicious. And I might swing for a TA intake. Yeah, it sucks. Am I angry? No. Just disappointed. Gonna have to put my job hunt into overdrive.

That thread was intended to try and diagnose the knock. This one is me confirming that it is indeed a rod knock.

Just pull it apart and fix it.

Add a Melling booster/wear plate to the oil pump. Get an adjustable oil pressure regulator kit from T/A. It will have be eternal oil pressure with the 350 oil filter adapter and bigger filter.

If you didn't continue to let it make noise it may be just a bearing. Or just have that one journal turned.

Keep everything else. Add a front Turbo Buick cam bearing.

Reuse everything else.

Doesn't cost anything to take apart.


Fix it. Walking sucks, ask for a job at the machine shop.

Already did that, but it's a great suggestion though. 50psi cold at idle, 23 when hot. 15psi per 1000 rpm (reccomended is 10) upto 3500 where from there to 6,000 it stabilizes at 50. I will do the cam bearing trick though.

Is there water in the oil?

Motors with 5600 miles and good oil pressure, and 8:1 compression generally don't ping and then rod knock unless they blow a headgasket.
No water or coolant in the oil. I've seen and had that happen before. Oil is a nice dark brown, has about 600 miles on that batch. The only thing I recall doing was moving where my vacuum advance was plugged in on the carb. For the past few weeks the car would idle like sh*t with the advanced plugged in to any port, but would run GREAT with it off. I think the timing was too advanced, but base timing at idle was only at 12btdc where I've had it since I built the motor. This weekend I'm gonna tear into the motor to inspect the carnage. A little part of me is still hoping it's not a rod knock, just a wrist pin malfunction, but I won't know until I tear it apart.
