Youre right it is, but the main seal doesnt seal the oil pump, it seals the crank case against the balancer. Only pressure it sees is crankcase pressure. If you looked at the oil pump, it is completely sealed within the front cover, if youre getting oil pressure to that seal you have bigger issues.
Plz look closely at the front cover before saying theres another problem. Ive been into about 100 of these engines i know exactly wat im talking about. A Grotor style pump uses a squish effect to pump a fluid.

almost all automatic transmission (specifically rwd, fwd can differ) use the exact same thing, the torque converter snout drives the oil pump, exact same design. automatics can run anywhere from 150-300psi line pressure. ive dealt with a lot of front seal leaks in automatics, if they blow the front seal out you have to pay close attention to pump body weak, the condition of the pump gears, and for blockage in the drain back cavity from around the front seal. ive had cases where people re/re the transmission 3 or 4 times to replace the front seal and cant stop it from leaking, its cause the pump is bad.
id be pulling the timing cover and inspecting the pump. take the cover off the pump and put a straight edge across it, use a feeler gauge, any more than .002" between the gear and straight edge, or between the side of the outer gear and the body and its junk.
btw: my 2.2l runs around 90-100psi, never had an issue.

U guys have no idea.
U pull the front seal the oil pump gears r right there.
Also the car has 3 -12 lines to a catch can. To top it off it has a crank case pressure sensor which shows a small amount of vacuum from the evac system on the car.

Soooo plz tell me how the front main seal dosnt see oil pressure wen the oil pump gears r directory behind it. The Grotor style pump that the ecotecs uses works off a squishing effect. Sooo with out a seal there the pump will push the oil right out.

you obviously didnt read my post. the pump gears have tight clearance to the body, this lack of clearance is what seals the gears to the body and keeps the pressure in the pump. yes some oil leaks past, but not full oil pressure, at least thats how its designed to work. excessive wear will cause more pressure loss and can lead to the seal blowing out.

Ive seen it where the ATI hub was machined incorrectly and rubbed the cover had to shim the pulley

As fun as it is to try to decipher what is being typed up about this oil pump I'm more curious about the suspension set up on this car. Foximus have you changed anything or revamped anything to go along with your new engine build?

So in 2015 we were sorta sponsored by BC Racing. Got a set of their BR type coilovers with SWIFT race springs. At the end of '15 we were changing rates around to make it better, but I still wasn't happy. The BC deal fell apart, so I paid a local company, Feal Suspension, to rebuild and re-valve my BC's based on the corner weights of the car. Effectively they are one off Feal's for a Cobalt. Never really got a chance to use them last year since the motor blew on the first lap.
But looking forward to see what they do along with a slightly tweaked geometry setup and hopefully some additional aero (as soon as I find the money for supplies)

We got the motor sorted out and making manageable oil pressure. working on some other aero parts in the shop, but sadly its looking like a lack of funding may keep us in he garage vs on track this year unless something changes. we have a couple irons in the fire for sponsor leads, but nothing secured yet.

We will be at Global Time Attack Pro/Am Round 1 On Feb 25th for sure. Hoping that a solid enough run will help us find the money we need for tires + entry fees for round 2 in April. There's just some stuff that's happened this winter in my personal and work life that means I can't afford to go all out of pocket like we have in past years.

First race of the season was yesterday. It went well, car had a few teething issues. We didnt catch that the hub on the blower is slightly misaligned.... belts dont like misalignment over 8k.
Trevor took a few photos / videos and posted them to CSS Gang on facebook yesterday. I was too busy driving. We will have a race report up on the team website, foximusmotorsports.com and some of the in car video and photos edited and up soon. Today is recovery day. after not being in the car for a year, im wiped out. in a good way
