Odd Oil issue

I take my car over (Insert Fast Speed Here) ((happy?)) mph often... I just installed a 2.3L motor about 3 months ago.. no issues till recently I am getting a engine oil lite flickering after I abuse the engine, but there is plenty of oil and oil pump seems to be working fine.. no shavings or anything.. Wondering it engine pressure has something to do with it, installed a Valve cover filter and killed the vent line to intake, since at these high speeds I was sucking oil out into the intake and killed a motor. Doing a BSD in the next few months to get more oil in motor. need to locate a oil baffle. So does anyone know the relationship of the oil pressure switch and the motor with this 2.3L?

Light flickers at idle, on braking, when under load, no issues, when not abused no issues.. I assume just get a Real Pressure gauge and find out the real deal, anyone install one yet?

A few questions:

1. Are you hitting those speeds on public roads?
2. What made you think you were sucking oil out of the engine?
3. Why did you disconnect the PCV system? (At high engine speeds, where is the increased volume of "oily byproducts", generated by the crank flying through the oil, going since there is no vacuum to open or close the PCV valve?)

I can see the advantage of disconnecting the PCV system but if you left the stock PCV valve in place then all that byproduct is trying to force its way up and out of the valve cover. If you don't want to get a PCV valve delete plate then you can gut the stock PCV valve (See sporadic's first turbo build thread).

My first thought might be oil temps; both because of the abuse as well as the desert temps out there in Nevada. If this turns out to be the case then something like the oil cooler kit from FSWerks.

Pull the balance shafts out & add a plug & stake it. Thats what I did. A baffle works for corners. I used a PT performance windage tray & their bsd plug. Look up the speed3 section.

Closed track.. the RPMs at them speeds is the issue.. not the speed. Edited the speed in original post as to not offend cops..

so anyway, the oil issue seems to be fine when the engine is cool.. it is 100 degrees but I have had this car in hotter weather..
get on it again today and sure enough same issue, I will change out the oil and see what it does..

BTW its the not PVC that is disconnected, that is still there making Positive air flow, this is the vent at the rear of the valve cover, and why did I think it was sucking out the top, simple, No oil in blown engine, thick oil film in intake.. muffler and that was just in three weeks of the new engine that has been replaced, beside 3 techs that were from the company who sold me the engine came up with same idea. That is why you should never use synthetic when you break in motor, never seen smoke since it wont burn easy to show that problem, here I am with a Breather Filter at the rear of the engine and not using a hose to the intake and I still have oil... when you hit 7k RPM it is not the same as 4.5k RPM.. it turns the oil into a mist in the valve cover.. sucks it out. So either a Oil catch can is needed or a filter, since I am not using turbo yet I went with Filter..

like this one...

I still have the OEM oil in motor to break it in, maybe its time for the Synthetic and BSD, not even 2000 miles yet

I would agree with this.

From what I know about the PCV system, air enters the valve cover from intake system (after the MAF so its already metered), flows down through the engine collecting contaminants finally exiting through the PCV valve to go back into the intake manifold to be burned off by the engine. If you pulled the PCV hoses and left the stock PCV valve, the valve is closed and probably won't open letting the nasty stuff out.


I would suggest the balance shaft delete and get the crankcase venting system setup correctly. Maybe even look into a oil cooler. IIRC the Ford Escape has a oil cooler setup from the factory; the oil filter adapter bracket will bolt right onto our engines; just need to find a suitable place to tap into the coolant lines after the radiator.
