Interesting oil consumption issue

[blacksambo]

Let my truck stand in garage for a week with a half quart of Marvel Mystery Oil in it. Consumption went down quite noticeably. Ticking long gone since the introduction of Marvel.

Did you put it in the oil, run it, then park it or pour some in the spark plug holes and let it sit? I really need to start doing something about mine before it gets worse. Now that I have the Volvo, the Rodeo sits most of the time anyway.

The Amigo won't be seeing hard 4 wheeling anyway so I'll take the risk. The secondary reason for me picking this Amigo as a DD is that if I ever have an accident, it'll be a 5 speed donor to the VX. The 3.2L may have been used for the same purpose till I noticed the oil consumption.

The 98+ DOHC 3.2 can be rebuilt as a 3.5 with the upgraded pistons that eliminate the oil burning issue (more holes in them). Its the same block and heads. Need the crank, rods, pistons, rings, and oil gallery of a 3.5.

pcv valve is most likely the cause.plug the hose going to the intake and put a small valve cover breather where the pcv valve goes and solve the problem. mine ate 2 qts in 1000 miles did this and back to 1/2 to 1 qt in 3000. trust me it works.

Like the simplicity of this approach, maybe will try.

FYI I did not put the marvel mystery in the plug holes, used it in the crankcase only.

(Pyschos...haven't heard from you in a while? We're in Bolton Landing quite frequently. Maybe meet up sometime?)

i have been cleaning my pcv with carb cleaner about every 3 days and i havent lost any oil yet - first time since ive owned it that it didnt need to be topped off after a couple weeks - ive cleaned it after every oil change and i change the oil religiously but i honestly think this is helping and might soon consider the tiny breather if it can eliminate the need for me to keep cleaning the pcv

There's lots of threads on the subject. Use the Search function with "Oil Breather" & you'll find them.

The one point that seems important (but was only mentioned once) is that if you put a breather where the PCV is, make sure you cap off the hose that connected to the other side of the PCV.

Another little factoid (question actually) is that the PCV only vents one of the valve covers. Shouldn't both be vented to ensure that the pressure is balanced? Is there a cross over that makes that happen? What about etlsports find of a oil filler cap/vent/filter replacement for that side ... would that be a good idea if replacing the PCV with a filter/vent?

all very good questions - anyone ever find a breathing oil cap that will fit a vx? im seriously considering the pcv breather to start with - worst case scenerio i take it off and go back to cleaning the pcv every few days
