Sorry,but neither my LS1 nor the Hemi in my Dodge Ram truck use any oil between changes and both are driven with a bit of spirit.

black specks don't show up well on a black car, but my tailpipes tell the same story. i used to wipe the black off of the tips frequently, now they are clean and stay clean.

Despite improved build tolerances, ring sealing ability does vary from engine to engine and year to year. The other thing to remember is that moisture in the oil displaces volume, so just because the dipstick indicates no consumption does not mean no oil has actually been consumed.

The vacuum pump does not suck any oil out of the engine. It seals the rings, negating blow-by issues AND it allows you to remove the PCV, negating those issues as well. The extra HP is just a nice by product of relieving the motor of crankcase pressure resistance.

www.gzmotorsports.com is where I bought mine.

If you want more info or help with installation, PM me. I don't want to step on the toes of catch can vendors, I am not a vendor, nor do I have any affiliation with any corvette related business. I'm just a performance enthusiast. You can also search my username and vacuum pump and find some pics (ok maybe not so here is a link - V.Pump )

Oil and water do not mix and internal temps are high enough to evaoprate any moisture that may condense inside an engine so,no,water does not raise your oil level artificialy.

Try to tell that to the people who drive their cars 2 miles to work!

Believe me, it can and does happen all the time. This is why the D.I.C. will shorten oil change intervals if it senses short commutes and insufficiently high oil temps.

This may be a good thread to ask a question...Below is a photo of the worst looking plug (#8) after my recent change. The car is an '01 A4 with 20k on it. Would an oil catch can eliminate the oil that seems to have gathered on most of my old plugs?

What is your oil consumption rate? A small minority of 01s were heavy oil burners and were re-ringed under warranty. Do you see any blue smoke coming out the tail pipe?

Since we service literally hundreds of hemis in the shop,and have never had a single complaint of oil consumption,I would say you have an odd problem my friend.Ever since PCV was invented,oil vapor has been drawn into the intake and has caused no known problems.Measue that small amount of oil over what you say is 2500 miles and you can see it is a very small amount. Like I said ,it simply makes an owner feel better.I am quite sure chemists would be very interested in how you get water and oil to mix also.

haha your joking right? might wanna check lxforums.com chargerforums.com 300cforums.coom 300cforumz.com dodgetalk.com challengertalk.com etc etc and see what owners are saying bud. so your literally hundreds of hemis in your shop, are obviously more like 1 or 2 and the owners arent complaining because they dont know how to check their own dipsticks let alone measure how much oil they get out of the oil pan, or are to arrogant to notice the little smoke puff coming out of the tailpipe under loads.

need more convincing why dont you contact Franks Racing Incorporated or Power Ported Performance the 2 leaders of hemi building and tuning or even better yet here is a quick yahoo serach for ya on what owners are saying. TRY DOING SOME RESEARCH BEFORE TALKING OUT YOUR ***!

http://search.yahoo.com/search;_ylt=...&fr2=rs-bottom

or maybe google search if you prefer that over yahoo

http://www.google.com/#hl=en&source=...f349cc5b44f7e1

so my dear sir i CALL

This comes directly from an SAE-published white paper (2009):

In reciprocating internal combustion engines, the gas that leaks at the piston, rings and liner system is usually called blow-by. The blow-by is a complex mixture of air, burned and unburned gases and oil mist. In order to avoid external pollution, the blow-by is recycled in the air intake system. This is called Closed Crankcase Ventilation (CCV). The CCV is the cause of major issues as air intake system fouling, oil consumption and contribution to the exhaust catalyst poisoning phenomena. During the recent decades a quite simple oil separation system based on baffles was acceptable. Emissions regulations are now tougher and a more efficient blow-by separation system is required.
Oil slowly degrades catalytic converters and raises engine cylinder compression ratio by allowing carbon deposits to form on the piston tops. Certainly, people who keep ther cars for less than a certain number of years are not often concerned about this. However, the rest of us are more likely to want to keep our pistons and cats and clean as possible. That's why I use a catch can.

I am a fully certified ASE Master Tech and Service and Parts Administrator at a large Chrysler/Dodge? Jeep dealer and have been for 30 years,what are your qualifications? None I expect.Dont believe everything you read on the mostly uninformed internet,before you indeed make yourself look like an a$$!

wows really dont believe everything i read huh? wow there is tons of people reporting the same thing as me, then to top it off i provided pictures that i personally took of my personal car, yet obviously none of us know what we are talking about. and btw i gave up my ASE certification when i came into the army. i grew up in a garage that my father owned who was ASE certified, as well as being a factory authorized tech for the Big 3,.... so dont assume everyone on here but you knows nothing, and has no real experience. that my friend makes yourself look like an ***.

so because you are an ASE MT you know it all right? how about you completely measure out what you put into the next hemi you do, then right it down, when that vehicle comes back, measure what you take out, and report your findings. i did this everytime i did an oil change which was always done at 2400 miles even though i was running full synthetic and was always around a quart low. we could go at this all day, damn i know i could. i provided photo evidence, i provided customer testimonials, yet you dont even want to take that into consideration, and put it into thought that you may not know everything, or maybe wrong.

Thanks for the info/links Higgs--Sure makes for good reading!! Unfortunately, price is way beyond my present budget. Think I'll pick up a catch can to hold me until my wife wins the lottery.

Just dialed up "excessive oil consumtion in hemi engines.Guess what? Not a single one listed and believe me,we have an entire library on TSB"S and recalls!With the extended powertrain warranties,if there was a problem with oil consumption with the Hemi engine it surely would have been reported.
