Soon I'll be the owner of an L67 powered car (94). I asked Jim to get the SC oil changed since he is close to 105,000 miles. In order to get more familiar with the SC I'd like to clean it as other members have. Definitely the outside, but was thinking about taking it apart to make sure everything was in top shape.

If I plan on taking it apart this summer, should I have him change the SC oil now? I don't want to pay money for an oil change if I will be taking it apart in a couple months, but I want to make sure the oil is good when I get it.

Would two full days be enough for a newbie like myself and possibly another person to take it apart, clean it, and put it back together? (was wondering if a weekend was enough time to have it back together for work on a Monday) I'm not mechanically challenged, just new to all this SC stuff.

I apologize if this is repetitive to most.

I expect to be in this forum a lot and look forward to learning from all of you about the whine makers. Thanks, much appreciated.

The good news is you aren't far from the BonneVilla. (aka my place). I've had some good sc learning over the last few months and have a couple in pieces that can be looked at during NEBF.

I think a weekend is enough to pull the charger, take apart if necessary and change needle bearings/coupler. It'* a matter of having a press available.

That is very good news!

I think a good bearing check on it would be best first. You may not need a rebuild, and just go with the coupler. See what it looks like when you get it, then buy the parts and make your plans.

You've seen this, haven't you?

I do plan on finishing most of it next weekend.

Usually once a year for a change is sufficent I think.
Seems to last a long time, 100% animal fat or something like that.


i just realized you just bought a bonneville with the metric dash configuration

I have heard that 50-75K is the recommende change interval

Yeah, it is.
However, its easy and cheap enough to do it once a year, why not?
Supercharger nose drives are pricey when they go...
Pete, once a year, and your set. Unless that SC growls, which, i doubt it does, I wouldnt even worry.

And this information is from who? GM?

GM states that it'* sealed for life. Where did you hear this Pat?

My personal preference is twice a year, but I'm spinning faster than most (and much more resistance and mechanical wear). I'd rather do it a couple times a year to prevent having to rebuild nosedrives. And I rebuild my OWN. Think about that.

Yes, yes I did I'll see if I can confuse a few of my friends here once I get it.

So changing the SC oil is cheap huh? I figured it was, but wasn't sure. For some reason I thought I heard sometime a long time ago (or maybe I read it) that the SC oil doesn't have to be changed until 100,000 miles. So that'* why I figured I'd get it changed now. I know the oil smells horrible, so how would I know if the oil was bad, or if it was ever changed?

Of course, if it'* a good idea to get it changed once or twice a year I'll definitely do that. Are there any links on changing the oil? (I'll do a search in the meantime)

Bill, I have looked at that page and look forward to using it when I do some work on it! It looks like it will be very helpful.

I'd like to handle all of the SC work on my own rather than having someone else do it. Even though I'm new to it all I don't feel it would be too hard. I just hope I have the right tools when I get around to it

Techinfo has a SC oil change/flush procedure.
