Whats needed for TT Install?

ZOperaMan

This is what alanforn said: "One thing that has occurred twice now is low oil pressure light (on the tach) has briefly lit up, once as I was letting the car cool down after a drive and today as I was braking and turning into my driveway. When the light comes on (second or so at the most) the idle dips briefly with the light almost to the point I think its going to stall." ( Whats needed for TT Install? )

Mine appears to be doing exactly the same thing -- I braked, turned, and just as (or just before) I let out the clutch there was a slight dip in RPM, and light flickered. Only thing I noted is my light isn't on tach, it's on left fuel/temp/info display.

I never see the oil pressure light any time the RPM is over 1000.

Since my pressure was normal when analog gauge connected and RPM's dipped below 600, wouldn't you think it was something with the fitting or pressure switch, and not a serious problem?

Thanks,

I'll contact AAM this week and see if I can get a clear explanation and report back.

THANKS! By the way, tell them I've found four (4) forumites that have mentioned this issue, all who have the AAM Oil Pan Spacer:

1. ZOperaMan (me)
2. alanforn (you)
3. Ill ( Low Oil Pressure at Idle )
4. Aviator44 ( Low Oil Pressure at Idle )

I know "correlation is not causation" but they should definitely investigate.

I certainly will, should have a reply tomorrow.

Just to follow up on the intermittent oil pressure light appearing after AAM TT install:

I did contact AAM via PM, but never got a response.

After a couple of tuning adjustments, and about 1000 miles of break-in, I no longer see the oil pressure idiot light flicker. The idle speed may have been adjusted slightly, but it still idles as low as 800 RPM. The only factor I can think of is oil weight may have changed after break-in oil change.

I still want to get a real oil pressure gauge with sender; just need to figure out best configuration that will keep both factory switch and new pressure sensor, along with the AAM tee fitting.

I dont think your video matches his description at all to be honest. Your RPM never dipped much if at all, and certainly did not appear to almost stall.

As for if your problem is a serious one... hard to say without knowing the cause. If there is a leak in the oil galley gaskets or a bad oil pump or something, it could certainly be a very serious concern. But if its just the switch, it wouldnt be a big concern other than to replace the switch. I dont see how the fittings would cause it unless they were very very restrictive and not allowing the switch to see the pressure accurately. You may want to confirm that the turbos are being oil restricted to their specification since over oiling the turbos could over tax the oil system and reduce pressure at all times, causing the light to go on at lower pump speeds, possibly.
