I finally got my new engine (big bore b20) in the car, the cam broken in, and decided to take it for some quick break in miles. I made it about 15 miles before I turned right, to head into Las Flores canyon in Malibu.
I made it about 1000ft. before it made a big bang and I started hearing some rattles. I immediately got under the car to find some oil leaking off the speedometer cable support. It looked like some oil coming out of the rear main seal and wasn't enough to make me really worry. So I decided to turn around and nurse the car home. The noises went away as I slowly approached 60mph. Still I was headed straight toward the garage.
As I pulled off, I downshifted into 3rd, and the noises appeared again. Only this time they stayed long enough for me to actually listen. The first three gears were whining, almost as if I had straight cut gears in there.
Then I noticed the pilot bearing making a noise. As soon as I disengaged the clutch it would go away, release the clutch pedal and it was back. I made it two more blocks before I lost the ability to get into 1st. I turned the car off, put it in first, and tried again. As soon as I shifted into 2nd, it went BOOM! I looked under the car to find a BUNCH of black oil (not the brand new oil from the engine which is actually green) covering the midsection of the car.
We flat-towed it the 6 blocks back to the garage, slammed it into reverse, and willed it into the garage where it now sits on stands.
Any clue where I should start looking? I know the transmission needs to come out, and that it's internals are probably shot (haven't drained what's left of the fluid yet but I have a feeling there's gonna be chunks). I don't understand gear boxes or know really what I'm looking at.
Should I be looking to replace it?
A friend offered me a complete m410 but I don't know if that'll fit in a '68 142s.
Should I just do the t5 swap now that I have to replace the transmission?
I have no idea what I'm doing
