I have joined the fuel starve after 6 gallon club.

That's peculiar.

Really hard to find the common denominator among you guys. Search the old threads and Savington and Emilio both swear there is no such thing, as long as the OEM sock is used.

Emilio's motor uses a lot less fuel than a turbo one.

With street tires? Your **** is seriously fucked.

I messed with the pump mounting over the winter. Maybe I raised it up too much.

Or you put the sock in the way that you think it goes, which is backwards from the way it goes.

It also still randomly smokes like crazy. At idle. Then clears up. Then comes back sometimes. Maybe it's overfilled? I need to make sure I have the right dipstick installed.

The one on the engine, or the one behind the wheel?

Both need to be checked. No smoke when driving to and from the track.

maybe I just overfilled it.

Crankcase vent on the oil pan is a definite fail. Filled a catch can in 2 sessions. Luckily Baxter's had the 10an caps I needed.

Getting a pretty good oil pressure drop under braking. 20psi at 3500rpm.

Car is awesome. Dual port wastegate will do 5psi all day at redline. I ran a 1:29.9 which is a PR by over a second I think. Very fun. Lots of torque.

Track day next Thursday. Need to figure out the smoking. Might have time to figure out the fuel starve

mmmjesse

have you ever taken oil pressure before and after the filter? like at the plug in the oil pump vs where the stock one goes in the VVT supply line? I am having wired readings from my stock gauge and i put a simple mechanical gauge before the filter that shows 20-30 psi more.

My oil pressure is in a sandwich plate. So pre filter. I believe.

Because 9,000 post, I don't remember and am not searching back. How was the block honed, and what rings did you run? I think you said the rings were setup really loose, that is going to let more oil get by of course. If you look down the sparkplug holes, are the tops of the pistons oily, getting drier as you approach the middle of the piston? If so, possible the rings are letting oil by at idle.

20psi at 3500 is great for hot oil pressure IMO. Like if you installed an accusump (OMG you should!), it wouldn't dump it's oil until under 10 for most applications.

Nice work on the 1:29.9. You've officially destroyed my PR, and I'm never getting enough track time to improve mine.

Pat, for your theory, he'd also have worse smoking when the pistons are cool, yes? With his EGT he could look at smoke at high EGTs vs. low. Not really piston temp, but good luck measuring that.

Rings are .021 and .019. So loose. But not that loose. Leakdown was all below 3%. I can do a compression test too ask see what's up.

For the record it only smokes at idle after a track session. All other driving is no smoke.

That sounds like a crankcase venting issue. ala the ol' full catch can routine.

aidandj

iTrader: (5)

Catch can did fill up. Failed crankcase vent. Then I drained it and got rid of the vent line. Catch can is just connected to the valve cover and nothing else.

I dunno, I have just observed that motors that burn oil from rings typically the tops of the pistons are more oily around the edges, and cleaner towards the middle. Cooler pistons/rings will leak more, but being cooler it might smoke less? I dunno, but from the pic with a cloud of smoke he posted, I'd at least look next time the plugs are out.

FWIW I have an accusump, mine is wired to be on all the time with key on just so it's always working, and reacts to a drop in pressure instantly vs relying on a pressure switch to drop, and then reacting to that.
