Yup. I was worried that I worded that wrong, I am aware simply changing the sensor alone won't do anything.

Would the tick typically be associated with low or high oil pressure?

Re: Can't get my wj outta 4lo?

Lifter tick is normally due to low oil pressure or a leaking lifter. There could be air in the lifter, which disappears after some time of running.

Well, that's the odd thing. You say it disappears over time...it disappears after running the engine for a while, then comes back on the next cold start.

Can low oil pressure be associated with a too high or low oil level?

Re: Can't get my wj outta 4lo?

Can be that a lash adjuster leaks a bit and looses some oil when engine is off, causing the noise the first minutes.
A too low as well a too.high oil level can cause oil pressure to be low. With a too low.level, the pump can take in air and this lowers the pressure since air.can be compressed. The same for too high oil level. The crankshaft counterweight can mix air in the oil, which becomes foamy. This foamy oil will be drawn into the oil pump with a low pressure as.a.result. But i think that non of the two is your problem.

Hmm, alright. We'll see what my new pressure gauge reads the pressure at, then work from there. As long as the engine is cold(and the oil is sittin at the bottom), no oil should drip out when I remove the old oil pressure gauge, correct?

Re: Can't get my wj outta 4lo?

A few drops of oil can come out, but nothin serious. The new sensor normally comes already with a red sealing material on the threads, so just screw it in and it should be ok.

The new oil pressure sender did have the sealant on it. Installed the new one this afternoon, wasn't exactly a breeze. Really awkward place to be using a big wrench.

Old sender:


What I used to get it out(true value lent me the 1/2" drive wrench):


Installed the new one, and it appears to be working properly. Oil pressure is reading a little above the middle:


Is this pressure alright? The needle moves just a tiny bit when I open up the throttle, it shouldn't be moving more than that right?

Sorry with all the questions...

Awesome. Now...can high oil pressure be associated with lifter tick? This is really starting to confuse me. Lifter tick only occurs on start up, and my car is running otherwise fantastic(not sure if because of BG44k or new oil is causing it, but throttle and idle are much smoother). But it can't be good either way. I mean, 10w30 IS the recommended oil viscosity for the 4.0...

Sure ...but according to your gauge you don't have that problem. If the tick settles down after a couple minutes running I wouldn't stress over it.

Re: Can't get my wj outta 4lo?

Its probably just a slightly leaking lash adjuster, which gets some air in it after standing still for some time. At startup it has to replace the air for oil (so is spongy and this could cause the tick) and as soon as it does it, the tick disappears. Nothing to worry about, as long as it doesn´t get worse.

What I don't understand is...why wasn't it there before the oil change...?
