This is my second oil change since the supercharger. I drove an hour to the shop and told the guy to measure how much oil is drained from the engine. This oil had about 3k miles on it. I run 6 quarts with the JWT oil pan spacer. He tells me 4 quarts came out. Now, I know the oil filter holds at least 1/2 quart and the oil feed and or return lines of the supercharger and the actual engine has oil in it. I know it's impossible to let all of the oil drain out, but would these factors account for almost two quarts. Does the filter hold more than 1/2 quart?

 

Do you have a Vortech? I do and I started burning oil extremely bad after 15,000-18,000 miles w/ the vortech installed. It started w/ a little black smoke at full throttle. Then soon progressed to more smoke coming out all the time. I had a compression check done and had 170 on all clyinders. I could not figure out what the problem was. Then I installed an oil catch can. Still smoking bad.... No improvment. Then a mechanic told me it was the oil rings that were going bad, not the compression rings. Also the car would tend to stall at a stop due to all the oil build up in the manifold. He had said w/ boost over time they will breakdown and oil will begin to slip by.

Make it short.. the motor was on its last leg. While it was still running smooth I decided to take it in and have the HKS F-Con installed hoping that maybe the piggy back ECU had some issues. In the shop we completly took apart the intake manifold and found all the oil we were looking for. Once the computer install it was still smoking and continued to get worse.
In the end the car was burning about 1 quart of oil every 500 miles. That became very expensive replaces synthetic oil all the time w/ the price of gas.

Now its in the shop getting a rebuild b/c I am embarrsed to drive around w/ a smoking car.

I hope your car dose not have the same problem, but that is my story about the oil problem............Good Luck.

 

I had a compression test and oil consumption test done before the Vortech install and both came back good. I'm not burning as much as you are, but you could be right about the beginning of the end. If he pulled out 4 quarts from the oil pan, plus 1/2 quart in the filter, plus maybe a 1/2 quart in the oil lines and engine, that's about 5 quarts, which boils down to 1 quart in 3k miles. I was hoping I was wrong about how much oil is in the oil filter, lines, and engine.

I'm not smoking at any time though and my engine had 79k when I put the supercharger on. I did switch to 10w30 synthetic instead of 5w30 and I'll look into an oil catch can.

 

I put my supercharger on at about 12,000 miles. Also when I got the supercharger I wanted more boost so I optioned for the smaller pulley which put my boost at 9.75psi (probably to high for stock block). Once I did that the smoking started to seem much more obvious. Start checking your oil dip stick once or twice a week and that will tell right there if oil is burning. I really dont think there could be 1 quart of oil left in the motor after you drained it. Maybe Im wrong though?? Also you had the oil consumption test done before the vortech (I hope it would be 100% before the Vortech install). Now check it w/ the vortech on. You are about the third person I've seen that thinks they might be burning oil.

I went to the stillen show last sat. and a guy had a Vortech on the dyno and guess what, he had small amounts of black smoke out the exhuast.
Anyways start checking the dip stick and see if its low after your oil change periodically. Good Luck..

 

Yeah, the oil consumption yielded no oil burning. No blue or black smoke from the tail pipe, although I thought black smoke is rich and blue smoke means oil burning. I guess If I knew how much oil is sitting in the charger, lines, and engine, I would know how much could've burned.
