Had to go out and climb under my rig to take a picture, this cover is easily removed, use a flashlight and inspection mirror, or get fancy and use a bore scope, check for oil residue on the flex plate.
Oil often pools on those bolts, being the lowest connected part to the oil pan, so people...
I came into owning a 55 gallon drum of Rotella Straight 30 on the cheap, so that's what the cruiser is getting for the next 20 years by my math :hillbilly:
Same here, I bought my 91 with "needs a rear main seal" but it was the pan arch. Pulling the inspection plate on the transmission and looking to see if the flex plate is dry or not is a good indicator.
