When there were no issues (in stock form) then they officially made the switch and didn't go back again.

If you are the second owner of the truck, check the hole. You never know what has been done before you.
Like said above, it is the only way to be 100% and it doesn't take long, but you're the only owner, you can trust those #'s

Makes sense. I didn't know if it was something like that, or they had surplus forged to use up, or had problems with the first batch of PMR's.

I'm the second owner, but I bought it a little over a year old. The guy didn't have it long.

That said I'm pretty sure my 3/4 ton has 1 ton springs, so... I'm pullin the plug. No clue what all he did to it.

Well I guess I mean where is it on the engine? Is that by the block heater or what?

It's aft of the oil filter on the drivers side of the motor, just forward of the bellhousing.

ok the sure way like the pics show is pull the engine out, remove the pan, and take the plug out and look in it. oh and shine a light underneath.

what are you guys using to pull the plug with? can't find anything in my arsenal that will fit.
also can't find a sn anywhere. I have nothing on my drivers side valve cover. any other place the sn can be found.
