First off i have a S13 with a 93 redtop pretty stock running 7psi

I was driving down I-4 doing like 75mph and all of a sudden i heard a high speed chatter(pretty loud) coming from the motor. I immediately shut off the motor and exited.

I am pretty sure i didn't throw a rod because the motor will still start

When i came to a stop i looked under the car and there was oil sprayed down the outside of the exhaust pipe as well as on the cross member below the motor. I then checked the oil and it was nearly empty...

Towed it home and put some more oil in it and turned it on for 2 seconds and got the same loud chatter. Looked under the car again and there was decent puddle of oil

This is what i think: One of the Seals (ie. main) went on the bottom end, causing massive of oil loss and the first thing to go was a rocker arm or something in the head.


What Do you think is going on. Maybe i am wrong. Any information or opions would be appreciated. haven't pulled the valve cover off yet.

Thanks for your help.
