InfiniteEvo's Wet Sump Thread
Anybody having issues filling catch cans in short time at under 500whp needs to be having a discussion with whoever built their engine, not devising roundabout ways to relieve excessive crankcase pressure without losing all the oil in their engine. These engines aren't rocket surgery.

2nd, catch can issues, full street setup etc is living, better than a "perfect build" in the garage with unknown ETA

So I lost another engine. I dont have an explanation from the engine builder yet on either mishaps, but theyve already mentioned about this new oil pan that they "havent read about before". The first motor was a bushur 2.0 and installed (2017) by Kozmic Motorsports, a reputable shop in Houston TX. Back then they didnt want to build motors anymore since they didnt want to provide warranty (IIRC). I raced it for a bit before the pandemic and I raced it full time 2021 - 2022. I installed the IE pan spring 2023 and about 3 events later and it spun #4 bearing autocrossing on GrandSport Speedway... its a track lay out and the slaloms are so open you tend to keep it at the very top of 2nd gear on and off for an extended period (8300rpm max) . I got the engine rebuilt by CP Motorsports, also reputable in Houston. They reinstalled the IE pan. I got about 2 events in and the GrandSport event came along and spun bearing #1 (initially thought it was the miver gear since its sounded different...I have yet to see the crank this weekend). same slalom section but CP set my rev limit to 8500
. Theyre confident with this build but only with e85 lol. Fine e85 only. Oil pressure was pegged 90-100psi on my gauge past 5k both occassions. I have no logging tho.
OK questions. does the oil push thru #1 to #4? does the #4 bearing get the oil last? or is it the other way? Is it possible the rubbery flaps on the IE pan were keeping oil from going to the oil pickup at high rpms? I need the info before I go to the shop
TIA

The oil pan didn't cause an engine failure. If it did, it wouldn't work in any of the cars it has been installed in.
The rods bearings are fed via passages through the crank from the main bearings. Main bearings obviously get oil off the main galley, so #1 is the first rod to get oil. So it would be odd to see that one fail from a starvation event. As a pressure drop would most greatly affect the #4 rod, NOT #1.

I was beating on the stock & buschur engines before this with similar e85 tunes, on the same track/layout and never spun a bearing before (i always did well on that track layout when my car doesnt break). I only upgraded the oil pan/regulator and the oil cooler before this. I dont have oil coming out with the blowby anymore on my newer motor if that helps. as mentioned, both times a bearing spun I was hitting the rev limiter and at the limit of the 200tw tire grip. as you know in autox we do those consecutively
