Series I Supercharger... making noise?

It'd not that you can't use motor oil, the question is why would you? The SC specifies a special type that can be picked up at any dealership for under $10 per bottle. I think it takes 1 1/2 bottles to fill. Do this every 25k miles or so, even every 50k miles would be acceptable. If it ain't broken...

so any 5W-30 synthetic oil will work on the stock supercharger?

For your supercharger application, yes. They reformulated the oil to non-syn after the M-90 (Series 2, 240 horse SC) came out.

I didnt know that. I am sure that is part of the debate between using motor oil in the s/c. Makes sence as I know that the m90 genIII needs special oil

2 bottles to be exact and if you need to buy a third and use some of that to top it off at the bottom o the treads.

well the car is running better now, we changed plugs, wires, fuel filter, and it still ran like crap, then we took out the air filter and its running alot better. still chugs a bit, so i dont know what else it could be?

Clean the MAF sensor maybe? Takes about 15 mins. Use electronic parts cleaner spray. Be careful handling the MAF, it looks like a cheap plastic part, but it's far from it!

how will i know if the MAF sensor needs to be replaced? there is no check engine light. in my camaro, the MAF is shot and a check engine light is on. when in gear and i hold the brake to the floor, and give it alot of gas, it chugs badly.

You don't need to change it. You just need to clean it. Make sure you have electronic parts cleaner spray. Otherwise it can leave an oily residue. BTW, did you change you PCV valve when you did your tune up?

nope, i should do that right?

and where is that exactly? im sorry im asking stupid questions, rivieras are just new to me.

Yep, it's in the top of the supercharger.

is there anything else that could cause the car to chug really bad when you hammer it?

About the only thing left is the coil packs I guess. But they don't go bad very often. Your using the higher octane gas aren't you?

well i just bought it last weekend, so most likely it has unleaded regular right now, but im going to use only premium now that i own it, that could be another reason.

Did you do the Seafoam through the Brake booster vac line?
and the gas??

I will testify that bad coil packs will cause it to run bad, but sooner or later it will throw a code. Same with the MAF. I had both issues, MAF and coil packs, both similar type problems.

Coil pack cause a serious misfire in cylinder #6 and cause vibration, bad vibration.

The MAF caused a serious hesitation like I was out of gas. I would hit the pedal and I wouldnt go anywhere for a second (or less, felt like forever).

Doing a top engine clean woudnt hurt. It is very very easy and kinda fun.

You could also try and clean the throttle body and check it out while you clean it. However I think the how to on the throttle body cleaning is lacking as I know how to clean it but not how to take it off!!! lol

i put the seafoam into the brake booster line and into the gas tank.

oh nm that then. Throttle body clean could be done. I hear it is easy, just don't know how to take the TB off...

when i went to change the oil, as i am going up the car ramps giving it gas, it sputtered really bad like it was gonna die out, i did new oil, new air filter, pcv valve, fuel filter, and a seafoam clean, and it still sputters real bad, could it be egr, need premium gas?

Where in Wisconsin are you? If you're anywhere near Stoughton, I could probably help you out sometime. I have a scanner as well as some known good parts (such as coils) that we could try.

i live in whitewater, so it aint even that far.

Ahh, UW-Whitewater is my alma mater. Well, I'd be willing to take a look sometime. My work schedule is never the same from week to week, and in fact I'm not 100% sure what it is like this week yet. I should be available Thursday and Friday.

well check your schedule and everything and make sure you can do it, maybe this upcoming friday?

Ok, looks like Friday is out. Thursday would probably work best for me this week.

ok i'll let you know.

been searching the web for the cheapest prices and came across PSE supercharger remanufactoring company and I just wanted to know if anybody has ever heard of them or new a better or cheaper company. I called and they said it would be around 700 bucks with a refundable core charge which they pay the shipping handling on. I have never bought any thing so expensive over the internet so would like to use a reputable company. Any advice at all wiil be greatly appreciated.
