OIL RESERVOIR CATCH TANK, they say they filter out sludge etc...is it a gimmick or do people here have them?

 

great question, been very curious about this myself.

 

I personally think its a gimmick

 

They may work, but if this is truely a problem, wouldn't the manufacture put one on the car as a standard item? Take care of your car as the manufacture recommends and you won't need these type of items.

 

hey try taking off your upper plenum and see how much oil you have collected before you pop off a comment...

 

Been there done that on many cars and I still stick by my comment. Go ahead and waste your money if thats your choice.

 

i usually only see it on turbo cars where the suction from the turbine sucks oil in from the crankcase ventilation tube, thats when it works well

 

there is a lot of suction in out engines without FI thats why we all burn oil up to 1qt is normal per a change in out car

 

I had one on my GST. If you do get one, dont go spending $100. All you need is a fuel filter. Cut the line and put the fuel filter in, does the same thing for $4. IMO its not needed either.

 

+1 ^
Been there, done that, and your're right.
I'm just waiting for some warmer weather before I install my oil catch can.

 

Here's a thread on making one instead of spending $100+ for an aftermarket.

lol...love some of the comments here about the known high vacuum VQ not needing one
For those ppl, take your plenum off and report back here as to what you see in there. The catch can will prevent a lot of that from getting in there.
It's not a gimmick.

 

great find 06CPV35..so my next question is..once its installed it will start catching right away..should i routinely empty it..or is this a once every 3 months thing..or should i check it after a long drive or so?can this hard the engine in anyway?

 

When I installed my spacer, I noticed a little bit of dried oil stains, but certainly not a lot. Easily cleaned up. I wonder if some cars experience more of the oil in the plenum that others?

 

It's a long thread I linked, lots of questions asked and answered in there.
No it doesn't hurt engine and with the clear bowl as the catch can, you can see how much it's collecting and empty as needed.
Yes, some VQ's collect more oil than others. For sure the rev-up VQ's. They known for higher vacuum issues than non rev-up and noticed reductions in oil consumption with this catch can mod in relation to what their dip sticks told them.

 

15 bucks for the parts to make a make shift oil catch can, and you dont have to clean up the blown by oil
