I'm attempting to purchase an updated cam button from a GM dealership. The P/N they have for a turbo 3.8L is 1250948. The number that I obtained from a search on this BB is 25532588. The dealership said that 25532588 is for a non-turbo and they are unaware of anything be "updated."

Which is the correct number for an updated cam button for use on the 3.8L turbo engine in my 87 GN?

*Points off for spelling and punctuation.

Mmmmm hmm. First off, you get 5 points off for failing to start off with a capitalized letter. You receive another 5 points off for lack of punctuation and 10 points for improper use of pronouns.

WHICH is the one they give on gnttype.org? Will it work?

Thanks, Steev.

I think you can get them aftermarket too perhaps Melling or some other gear/chain vendor.

My mechanic said the updated roller button was available when he did the timing chain on my GN.

Didn't see him put it in though.

Thanks Zap, but none of the local parts franchises have cam buttons for a GN and I already have the timing gear set.

How about this:

Could somebody describe the differences between the original cam button and the upgraded one?

A description could prevent the hassle of purchasing the wrong part. Thanks again.

There is no hope for Joker (he is another Herb Fishman)


If the GM dealer has the one mentioned, I would just get it. Why in the world would there be a seperate one for the turbo cars, I wonder?

Yeah, the originals (at least mine... 84/85 Regal T's, 84 Riv T) had a plastic button on the end of the spring...no needle bearing.

According to the dealership parts counter, there are different models of the 3.8L: The 3.83L and the 3.87L. I didn't question this, however.

Are you sure? You may want to get out the machete, hack your way through the shoulder-high weeds surrounding your car and check again.

I just got back from the dealership (and speaking to a different parts person). P/N 1250948 is the original or plastic cam button. P/N 25532588 is the updated or needle bearing cam button.

I forgot to mention that the initial parts person insisted that I couldn't use the updated version in a turbo motor. At any rate, problem solved.

Oh yeah...one more thing. The second sales person said that the difference in engines is that the turbo version is 3.81L vs the non-turbo 3.8L. Anybody know about this?

Zap, I know you're probably busy breaking your car out of it's weed prison, so don't feel pressured to contribute. Tip: you may want to tunnel in.

Hehehe...the second salesperson is just slighty less of an idiot than the first one...3.81L vs 3.8L...what an idiot!!! At least he knew the roller bearing cam button was an updated one and could be used...

I'd find a different dealer to go to...
