First off I must say I am glad I am doing this as my car has 19k on it and do not know what the shaft would look like at 50k. OK so as most cars with some mileage there was some oil sludge/vapor build up within the upper plenum so I decided to clean everything including the square orange gasket , I did not use any solvents just an old t-shirt. When I went to replace the gasket it had expanded and is completely unusable as it would not sit correctly within the lower manifold any longer. Now my car is apart for 2 days waiting for a replacement. SO for those of you planning to do this either get a replacement gasket ahead of time or DO not remove it from the lower manifold.

On another note the oil accumulation has led me thinking into install a catch can, what do you guys think :hmm:

You know how I feel about the catch can. I must say that shaft is seriously worn.

Also, I love your threads! They are always helpful with pics too.

Thanks for taking the time to post up.

I've got one of Jesse's isolators, and I think this post has convinced me to get off my a** and install it sooner rather than later. That shaft looks really bad ... ! Thanks for this post X2.

Great pics. Remember the so called "shaft" is just a locating stud to keep the spring somewhat centered. It does not do any work. The 3 pins and the isolator transfer all the power.

I disagree that it's not usable. I just had my blower completely apart twice last weekend and while the gasket seemed to have expanded a bit, it will still tuck in nicely. You just have to work with it.

You might try cooling it to make it shrink a little. Just don't let your wife find it in the fridge.

Do you guys have to sneak mods behind the wife's back or something?

I thought every guy knew about "shrinkage" in the cold? :sneaky:

I had to spray mine with Nitrous to get it to fit. :)

This is what mine looked like when it was pulled. Yet GM swears there is no issue with the design... Hmmmm

Yes you are correct and it is important for people to remember this as it may not be worth the trouble for some people but it was piece of mind for me

Not in this case, the gasket clearly expanded large enough it would have never sat correctly and I was not gonna risk trying to squash it in there not knowing if it would lay flat or not.

Everyone I have done has been like that. Some take a little work to get it to stay in place but keep trying it will work.
