EA82T Oil Pressure Question
Posted 18 October 2013 - 10:18 AM
The oil pressure unit on the front of the motor is new,@rebuild. Could it be the oil is to thin? Is this from the "cracks "that these motors are known for.
I do need to replace the pan gasket as it is leaking but could it cause this once the oil has warmed up?
Please give me your .02 cents on this as I have not ran into this before.

With my experience with ea82's the oil pressure will read near zero when the engine is at operating temp and at idle. It should move towards 40 when operating at highway speeds. What weight of oil are you using. I recommend 10-30. 5w is too thin and is bast for sub freezing climate.
Check for leaks at the cam tower o-rings as this is one place that can lose oil pressure.
The stock gauge is notoriously inaccurate. You will most likely get an actual reading using a manual pressure gauge, or even an aftermarket electric unit.
The oil pan leaking will not lose oil pressure, although tou will lose volume of oil.
Also, make sure the PCV valve is functioning, the hoses to it are not clogged, and that the oil cap is secure and not bouncing around. The ea82t requires the oil cap to be present and sealed for the pcv and air metering to work properly.

I can't post pictures of anything as I access everything on my phone, no internet here in the sticks where I'm at.

As Miles typed, the senders and gauges are notorious for not being accurate. I had one that read negative... If the oil pressure is really low, you are likely to hear the HLAs clattering.

These engines dn't do the exteral head leaks, so anything you read about that does not apply to the ea82. But the ea82 has it's own bugs specific to it. Take care of the cooling system and the ea82 will take care of you.
