Here is an update on my issue with the smoke bombs in left handers -

I installed the EBS Racing Oil Sump Baffle and the Brey-Krause Deep Sump Oil Pan Kit with the oil pick-up extension. I did NOT end up replacing the AOS because it never smokes in normal driving, and seems to have the proper amount of vacuum when opening the oil cap while the engine is running. Plus, I looked at the difficult access to the thing, and suddenly got lazy and skipped doing that.

I filled the oil to the third line below the top on the digital readout, Mobile 1 10-40.

Yesterday I went to another track day, this one at Pacific Raceways near Seattle. It has two long left-handers, and a tight left-handed hairpin.

My results? Bad! It is still smoking huge amounts when in a left hand turn under hard throttle and cornering. It was bad enough on the first lap that they red flagged the session because they thought I had blown my engine and oiled down the track! Very embarrassing, to say the least.

So I tried to drive around the problem, by running in a higher gear. It would still smoke, but not as bad. Then I tried essentially coasting through the turn in the higher gear, but then the low oil pressure light started to flicker. If I ran in the proper gear, but with higher revs but not really much throttle, then the oil pressure light stopped flickering, but it smoked more often. I even tried putting the clutch in a coasting through the turn (it didn't smoke!), but with other cars on the track, that wasn't an ideal solution.

Since the oil pressure warning was very concerning, I added another quart of oil, because I thought maybe I had burned off so much oil the four or five times it smoked that the oil level was low. The problem persisted with the oil pressure low light, though. Today I checked it after the car sat overnight, and it shows one line on the digital read-out! When I said that it was smoking a lot, I guess it really was!

Also, the brakes started to fade away, but that is another issue. I guess EBC Reds aren't suitable for track use.

That leaves me very frustrated! The handling is very good, the one series of corners that I could go through at speed nobody else was as quick from what I could see. It is fun to drive a car that you can steer with the throttle. But unless I find a track that runs clockwise, the car is unusable for track use.

At this point I'm pretty disillusioned with this dammed car. What really frosts me is that after spending over $500 on the Krey-Brause sump and EBS Racing Oil Sump Baffle, I have oil pressure problems in the turns (but that may be because the it burnt so much oil that the level was low). The tires I'm running are regular high-performance street tires, not R-compounds.

My step is to go ahead and replace the AOS, just because I don't have any other ideas. Anyone have any other suggestions?
