VX Weirdness

[nfpgasmask]

I changed the oil tonight. Just like I always do, every 3000 miles. Except this time, my PCV valve was all goobery and there was a lot of oil that looked like it spooged up and out around the valve, which I have never seen happen before, and I usually change my PCV every, or every other oil change. The other weird thing, is that I drained my oil, just like normal, and for about the same amount of time, jacking up the passenger side to get as much out as possible. Typically, I can use one whole jug of Mobile-1 oil (5 quarts) and it fills me right up to the fill line on the dipstick, usually with a very little bit left in the jug. This time however, my VX took the whole jug, and there was nothing registering on the dipstick at all! I had to crack open another jug and add about another half quart I would estimate, and probably 3/4ths of a quart to get the oil to the fill line on the dipstick.

Now, the only thing, is that last Satuday I installed a brand new EGR. Could this have anything to do with this weirdness?

Thanks - Bart

Ok someone else that has this issue....I fill with 6 qts each time as i found that in the manual somewhere. My dipstick rarely registers any oil on it.

Hey J,

First off, let me just say that my dipstick DOES register oil. But usually, with an oil change, I could top off with just one 5 quart jug. And now, this time, for the first time, it took more than 5 quarts to top off the oil...

I mean, its going somewhere?!?!?!

It sounds like you might have some slug in the oil return holds on the heads. You might want to pull your valve covers and do an inspection. I had that issue with my Montero.

I have no idea how to do that. I mean, everything is running good. No knock, etc. Do you think this because of the PCV valve issue or because of the VX taking more oil or both? Could changing the EGR valve have anything to do with this?

Yeah I have no idea what he just said...

I have always put 6 in. I know it goes in, and I never have leaks. No knocking one bit.
I do have the mild diesel sound coming from the loose nut.

Sorry, I’ll try and explain it a little better. When the oil return holes on the heads get clogged with carbon slug produced by combustion it can slow and sometimes stop the flow of oil back to the oil pan. If your seeing seepage around the PCV valve there’s a good chance the valve cover is filling with oil because the oil return holes are restricted with slug. I had this issue with my old 91 Montero about 3 years ago. I ran some pipe cleaners down the return holes and it seemed to take care of the problem.

That would also explain why your oil level is off. There is still a lot of oil up in the valve covers. I try and find some examples of this.

Well, what I am going to do is just keep checking my PCV. Like I said, normally I swap it for a new one every other oil change, if not every single oil change. This is the first time I have seen oil around the PCV. It's possible the PCV was just clogged a little. I will look at it again soon and see if there is more with the brand new vavle in the there.

J, no loose nuts knocking around, except the ones in my shorts.

I checked in to some examples. If you where having oil return problems you would see other symptoms like blue smoke at startup and oil seepage around the valve cover gaskets.

It sound like your on the right track.

You recirculate the exhaust gasses in your shorts??? Novel approach, I must say...

LOL, sometimes I do, yes. But at night in the bed I prefer to create a "Dutch Oven" rather than recirculate. The wife hates it...especially when my dog is under the covers helping me out (cross pollination).

LOL, yeah, I feel sorry for her sometimes...putting up with me and all.

Cross pollination....man that was a great line....



So I most likely need to dig into my valve covers? Is this easy to take off? What exactally are the return holes?

Thanks.

Bart - sounds to me like it's time for a Seafoam-in-the-oil treatment.
