Elaborate please? puked mad oil out of the rear main?
Mine wont blow out the dipstick tube after the breather fix,
This is a forged motor with IIRC 7k na miles, and around 50 maybe boosted by me. Prev owner boosted it around 3k miles IIRC

Well i had a similar situation about two years ago. i wasn't losing oil to bad just a bit. but i had tons of blow by out the exhaust and each valve cover. blow by was so bad it would push the dipstick out of tube. end up doing a compression test. #7 cylinder was about 60psi lower than all other cylinders. ended up being a cracked piston. So id start with a compression test. ill bet youll find the problem there.

My truck went lean after i turned the boost up too much. Here is a pic of the damage. Oil coming out of the back near the rear main seal, breather vents, and dip stick. It took me 5 gallons of oil to make it 500 miles home. LOL

Sweet pics of the piston. Your lucky it made 100 miles what did the cyl look like? Just a thought but are you sure that the rear cover and the pan are mated properly kinda why kent moore makes the big tool kits for these ls based motors to assure alingmnt of covers. Just putting it out there.

where is this at? my sensor has been a bit wierd, and i get oil on the driveway every night..the rear main is new, and i can see inside the trans inspection hole and there is no oil in there, it just runs down both sides of the motor and drips off the bottom of the pan..
