The verdict is in,

Just got done completley ripping my engine apart, had a really loud banging noise!


Spun rod bearings 1 2 and 4, Ruined #1 crank journal, everything else suprisingley is in good shape, Im gonna finally be able to drop the goods in and get it back in the car, allthough 3 boxes that say cosworth on them do look good sitting in my room hahaha

when did you first notice the banging sounds

 

[MZR23MZ3]

when my oil light came on lol, stopped on the off ramp and cut it had it towed but it was too late, idk where all my oil went, pump looks good, seals look good rings were good valves look mint.

that blows wonder why it went bad it sounds like the engine lost oil pressure at some time obviously. can't think how though if the pump and seals "look" good. where did the oil leak out of

 

[verto]

maybe taking a right hand off/on ramp too fast?

lack of lubrication from the oil (oil starvation), excessive engine rpm, long periods of high rpm operation that sort of thing. possible to starve the oil pump by cornering very hard as someone else already suggested. Good idea to install baffle plates in the oil pan if you do lots of hard cornering.

found the culprit, haha i cant belive I didnt see this sooner my number 1 lower compression ring and oil scraper ring were very brittle and when i tried taking them off unlike the other ones they cracked into a few pieces, they were not good, Also i found a piece of ring in the pump,


Total so far

3 rod bearings
2 rings
1 Oil pump, allthough it was working not gonna chance it, could have been un jammed later?

I just drove the car normally I havent really beat on it and dont take corners too fast......
