I think this could be bad...

Stretch bolts do just that, they stretch when you touqre them.
So if they are 2" long in your hand and you tourqe them to spec they will be longer then 2" and then they want to contract back to their orginial 2" so they are always applying pressure.
These are a ONE TIME use type of bolt, if you try and use them again you will either snap them in half or they will never get tight.
These are common type of bolts for holding cylinder heads in place as well as rod caps, basically anything that is under extreme pressure/cyntrifical force.

well does anyone know if my motor has stretch bolts? 98 4.0. Also, the tap goes with the engine, once per rotation. I have to get home to see if the metal is ferrous. Sure wish i read something like this, I researched the crap out of ATF flushes on the site and seemed to find positive results. Not sure if I am going to fix or just sell anyway. I have had nothing but problems so far, and haven't even been able to utilize its abilities yet.

$80 and you have new ones.
I have no idea if they are stretch bolts or not.

well i just checked the metal flakes, they are non ferrous so thats good, that info along with the tap frequency lets us know that it has to be a rod/main bearing. the oil pan was full of sludge, so i know I had to have dislodged alot of crap. now my nex question is if it is a main bearing in the crank, thats a full dismantle to get to those? What are my odds that it is a rod bearing......be gentle.......

No engine will benefit from an ATF flush in any appreciable way. It's a placebo and as we're seeing from this thread, it has risks.
