What was your oil pressure before the failure?
Yeah... What Zealous said.
I will confirm what went wrong when I tear it out and apart, but I'm pretty sure it spun a bearing due to oil starvation.
I just got home from an all day long adventure to get this motor. The engine I got was a really good deal. The valve cover has been powdercoated, but it was a bad job. Gonna need to get that redone.. But the motor came with a 626 intake, a probe trans, and the coil pack conversion.. So that's cool. (I'm gonna be stealing the 5th gear from the probe trans)
There is a fair amount of gunk on the intake valves and overall the engine looks a little old. I think I'm gonna change bearings, use my MSP head, and change the headgasket. I was able to get the trans off and all the accessories off but I am too tired to do any more, so I packed it in and came home.
I'm having to work on it at the shop at work, so thats a little bit of a drawback but at least I am moving forward.
Over the course of the week, I will get it on the engine stand and start taking timing s*** off so I can get this pump on. I'll do a new waterpump, but I'm reusing my timing belt since it has like 7K miles. This is not a forged build, so I will save money wherever I can.
My biggest hurdle right now is learning how to "mic" the crankshaft and learning how to change bearings properly (this will be my first time)
