Yeah I agree.

Do you guys think that a bad lifter can cause low oil pressure? Because I have one lifter that is pretty loud. I took off the valve covers and checked each one for preload on the base circle of the cam and didn't have any play on any of the rockers. So I don't know why it's so darn loud.

I don't think so. Seems unlikely

A bad lifter will not affect oil pressure. Usually it is bearings or oil pump related will affect oil pressure. Have you hooked up a mechanical gauge? This will rule out a faulty sensor. Also, check/replace the screen under the sensor as well.

morepowerjoe · 10-04-2021, 01:49 PM

No I haven't hooked up a mechanical gauge. I just really think that the ecm oil pressure is correct. But I'm going to change the lifters out because I have had one that's been a problem every since my cam install. Once I get it back apart though I think I will replace the oil pressure sensor.

AlanRubin · 10-04-2021, 02:33 PM

You need to pull the pressure sensor, and then screw in a pressure sensor gauge.
Bad lifter won't cause lower oil pressure, as stated.

Greenhornet2 · 10-05-2021, 08:05 AM

Even if you are planning to replace the lifters test the oil pressure first. Why throw parts at it, put it back together then still have an oil pressure problem? You'll be pulling it apart again. Unless you plan to pull your caps and inspect all the bearings when you pull it apart this time.

morepowerjoe · 10-05-2021, 08:22 AM

I'm not crazy about screwing with the oil sensor while the intake is on or removing the intake putting the mechanical gauge on and then replacing the intake and then starting it up to check the pressure. I was wondering if I could check the pressure with just cranking the engine over? But the starter probably doesn't spin it fast enough to check the pressure does it? So how would you do it?

gtstorey · 10-05-2021, 09:18 AM

I would install a tee so the pressure sensor and gauge could be read at the same time. I probably would install a mechanical gauge inside the car, with the oem sensor until you get this resolved. I might even just replace the oem sensor while I'm at it.

I already got this one.

I’d suggest removing the threaded galley plug on the drivers side right above the pump and then buy a mechanical guage kit. They make total kits that literally screw right into that location and then you have it. Look on eBay, Amazon, Summit…they are all over. (Search: M16 1.5 Adapter to 1/8 NPT Oil Pressure Sensor Adapter for LS Engine). Do this to At least to verify if your gauge is bad (which is my guess). Oil pressure fluctuating around like that is just odd. Sensors do go bad. All the time, unfortunately.. An oil pressure sensor is not immune to that.

That galley plug is easy access and a mechanical gauge set up is cheap. I’d start there before tearing into anything else.

cc-rider · 10-05-2021, 08:39 PM

Here is the plug and location where you can hook up a mechanical gauge without removing intake and messing with your current sensor:

Hey Thanks. That's what I was thinking about doing because the gauge I bought has a fitting that size.
