Bad Bearings :(

Yeah, Its got about 1/4" of movement up and down if I pull on the gear. Is that no bueno?

I guess it's just one of those weird situations... Only 135k on the motor, decently taken care of... Just a freak breakdown I guess.

It's this little thing called sh*t, it happens from time to time.

When I was young we used to own a 1982 Chevy Suburban, bright red with chrome trim and gold wheels with the chrome trim rings and dark tinted windows and air ride in the back. Nice ride. The original engine crapped out and dad put some good coin into it rebuilding it, stroker crank, lopey cam, ported and polished heads, high compression pistons, the works. It went like gravy for 6 years and 50,000 miles, until one night, just outside of Pendelton, OR, there was a loud clang and the engine started running rough and was way down on power, and the alternator died.

Sh*t. Backed up 2 miles to the truck stop that is now a huge deal with a casino and Peterbuilt dealer. Pop the hood, engine sounds like crap and the drive belt is not moving. ? So we camp out for the night under a light and the next day get it towed into the local shop where the mechanic discovered that fancy stroker crank split in two, likely from a hairline fracture that somehow made it past quality control.

Long story short, we rented a car, stuffed a family of 6 into it, and continued our trip. Come back a week later and all is good, and that rebuilt motor ran for another 100,000 miles before we sold it with 227,000 on the clock.

Our family knows how to put miles on cars...

^ holy crap! Well hey, at least the crank didnt cause too much damage to the block in that situation. I would love to have an old school 'burban...

dose the dizzy shaft have much vertical movement in the main body

Would this be a bad thing? its got about 1/4"

My new block had 13k miles on it, and I had the EXACT thing happen just two weeks ago. Don't have pics, but the gear was messed up...sad thing is, I never found the metal. Drained oil right away, and nothing..didn't cut the filter tho.

I was getting cam position sensor codes a couple weeks earlier and went away. Should have looked further when we saw those codes.

It was the original distributor though with 170k miles.

Not really the only thing I can think off at the moment is that maybe a lack of oil caused the cam to eat up the plate of front that holds it in and as a result of the angle cut of gears kept trying to ride off the dizzy gear and push itself away.

Seems pretty logical. Thats a ton of work to repair though...
