I just did a build that did 2 rod bearings 30km in, pulled it down and linished the crank today.

All bearings were a tiny bit scuffed and all crank machining measurements were well within spec, it just had low oil pressure, probably didnt prime properly or had air in the system. Getting a new set of bearings and an oil pressure guage and all will be fixed.

Ah, what can you do hey?

I think SprungMS should be put on suicide watch for the next 72hrs.

If you aren't planning on more than 200-250hp, the stock engine can handle that all day with a proper tune.

I'm thinking that's what it's gonna come down to. Not such a huge deal, but I was pushing more than that before... Not really surprised it spun the first bearing, I ran 14 psi on a 60-1 T3/T04E for something like 4-5 months. Not a low mileage motor.

I just don't know what happened. I suppose some RTV could have gotten lodged in the crank ceasing oil flow to a bearing, but other than that I have no idea. I had great oil pressure, 30 at idle, 60+ when on it. Oh wells. Time to find some more money to throw at my car.
