How's your oil pressure? Almost sounds like low oil pressure or even may have spun a bearing.Have u checked your oil like to inspect it?

Sounds to me like something loose and rubbing against something else. Flexplate bolts? Maybe flexplate inspection cover bent and getting hit?

The oil pressure seems to change a lot like? Like does the oil pressure go up when u drive and goes back down when your at idle? If so im sure that is normal mine does that. When you rev it up does the clapping get louder?

You have real trouble. (yea, you knew that). Change it to straight weight oil, 40 or 50 if you can find it. Then some STP or something similar. Then keep the RPM's down and keep you foot out of it. Avoiding the freeway would be good. If you go around the distributor unplugging wires one at a time you can find the bad one. You might want to leave that one off. You'r not going far ether way. If you pulled the pan you might find some piston in it, would be my first guess because of the blow by, (smoke from cover). If it IS a rod you can try sticking some inserts in it but that won't last as the crank will have been beaten. I've never tried pork rind...guess they used to have it in bait shops!
You should pull the little inspection plate on the bell-housing over the flywheel(torque plate), and check the bolts holding the torque converter. Sounds like your engine, but that is an easy check...

Well I can tell you 100% not lifter knock at all not even close. Bad bearing's most likily, maybe flex plate bolts but, I'm leaning more towards the motor. Run her till it dies, by no means run thicker oil in it , that will only make it worse because thicker oil will have a harder time getting where it should go. Thicker oil does nothing but make it harder on your motor, I hate when people tell someone to do that it's stupidity at it's best.Pork rinds? I think you mean leather thats what they use to do, on the older less tight tolerance motors along with the thick oil for the OLDER motors of the 60's and ealier.

Hee Hee...Pork rind was a joke. They use to use it because it's tougher than leather, but I think it's a bit out of fashion. Agreed thick oil in a new engine in cold weather would be stupid. Thin oil in hot weather in a clearanced engine makes about as much sense. Got my 90 in 02 with a noticeable rod knock. Normally warm here but PO use to take it skiing allot and ran 10-30. Almost 10 years now on straight WT Castrol 30 WT and no problems. "stupidity at it's best" is working fine for me, thanks. Don

That one sounds very much like what i had, normal oil pressure, no miss fire
turned out to be a broken piston, no.6. The skirt broke off bellow the gudgeon
pin . No. 1 had a crack as well. Replaced the whole lot....

Agree with the previous post; I believe you're about to throw a rod right through the block. Sounds identical to what I heard just before I literally saw my buddies 6 throw a rod through his block.
