What is your VX Oil Consumption in 1000 miles? Part Deux.

[tom4bren]

when my vx was using a lot of oil it was the pcv valve. I had put a new pcv valve in and used 2 qts in 1000 miles. got rid of the pcv valve by plugging the hose and putting a filter on the valve cover. went back to 1 qt every 3000 . with mobil 1 synthetic. there is no baffle in the valve cover and if the pcv valve sticks open it will suck oil and burn it . you will not notice it because the cat will burn it and no smoke will show in the exhaust. shawn

Actually there is a baffle. A metal plate runs almost the full length of the left valve cover. But yer 1/2 right. There's no baffle on the right side so if you leave your oil fill cap off by accident, you'll get a nice rust protective coating of oil all over your engine compartment.

I've also removed the PCV but I used an oil catch can instead of the filter thinggy you described.

i really want to try the breather or catch can method but i have one thing stopping me - i dont understand how either would be helping - if the burnt oil is going out the breather instead of into and out of the exhaust, you are still losing oil and i would figure you would need to clean the breather filter constantly - the catch can is doing the same thing as the breather but catching in in a canister which if not recirculated you are still essentially losing that oil - i know i must be wrong but im too stupid to figure out where

yer not wrong ... just evil

Our biggest problem is the oil drain holes in the rings. Nothing is going to fix that other than an overhaul. You can minimize the problem though by adding a detergent just before every other oil change ... basically just keeping the insufficient holes operating as best they can.


Another problem is the PCV valve. It gets clogged so easy & that ain't good. The vent filter or the oil catch can merely replaces that valve with sumpn that doesn't get clogged so easy. In my case I installed the catch can alla way over at the airbox. This gave me a fairly long (& uphill) run on the hose coming from the valve cover (where the PCV usta be mounted). I'm fairly certain that it's allowing much of the vaporized oil in those gases to condensate on the inside of the hose & trickle back down into the valve cover. That's why I'm not collecting much if any oil in my catch can.

so with the canister it actually IS reusing some of the oil that would have been lost - that makes sense - im more likely to try the breather first but that seems like it would just vent the burnt oil into the engine bay instead of out the exhaust... then again my old firebird had a breather on the valve cover and it never burnt a spec of oil

side note - everytime i go to advanced auto the guys there want to talk about the vx - same 3 guys - they all have tuner cars and some of them are models ive never heard of or weird imports that are called something different across the oceans - they keep telling me to basically dismantle the entire emissions system on the vx - apparently these guys dont use any type of egr or pcv or even cat converters - they say not only does it help with stupid stuff like oil burn but you also usually get dramatic performance gains without the emissions crap - if i keep the vx and continue to live in indiana where emissions are not regulated on vehicles i might look into this

Not on purpose ... but that seems to be the way it worked out.

Emissions removal: Save the parts you remove. You know how lawmakers like to change stuff on you at the least convenient moment.

i work for the govt - i know this all too well

i would go just rogue and the vx will be for pillaging and/or supply raids

i wont end up taking off the emissions stuff any time soon anyways its my daily driver and i dont know enough about it to risk screwing something else up

[tom4bren]

It's a nice thought though!!!

I feel ya, working for the Gubmint. I are a 30+ year veteran of the Civil Service meself.

on a positive note - i have been checking my oil even more regularly since the new egr and pvc were installed - it ate oil like normal for about 100 miles but now i have went another 100 with no usage - im hoping its not a fluke - ive never went that far without the gauge dropping since ive owned it

[evillecutter]

another 100 miles and its back to normal - maybe a little less than normal usage - looks like that little bit without usage was indeed a fluke

does make me think that something had to go right for it not to use oil for a bit - now if i could just figure out what went right....

Ahh, fergeddaboutit! Mine did that too (once). Then back to the usual quart every 1000 miles. At that rate I dont bother to change my oil, just the filter.

[Maddawg]

Ok, it did it again (twice now) and coincidentally a year ago. Checked it my usual 1000 miles and it was only less than a 1/4 quart down from full. Go figure.

Happy oil consumption relief day...

What type of detergent do you use?

PROTON, of course!!

Love it and as a Proton owner will use it.
