cleaning iacv, do i need to buy a gasket first?
i have a 92 se. i've read lots of threads suggesting cleaning the iacv as a good cheap way to potentially tune up the idle a bit. none of the threads i've seen mention buying a gasket. is there one that needs to be replaced when i take the iacv off to clean? the 2 nissan dealers closest to me are an hour each way, so i'd like to order it ahead of time if that's the case. i couldn't find a reference to any gasket or seal in the fsm, but just to be on the safe side...

They only cost a few bucks at the dealership, but I would make sure you have one in your hand before removing your IACV. No dealers in my area had one in stock and I had to wait several days for one to arrive from California.
I made the mistake of removing the TB and IACV, then going to the dealer to get the gaskets. The car sat in the garage until IACV came in.

ordered a gasket today, $10.25 Canadian. not bad at all. while on the phone with the dealer i priced out anti-squeal hardware for brakes (metal shims). they want $66 each set, front and rear. ouch. internetautomar, do you stock those shims? couldn't find them on your site.

The better quality brake pads come with metal shims attached. You dont need to buy seperate shims.

So for your car you need an IACV gasket to clean both the TB and IACV.

Wake up you 2
(alex,read his info under his screename)
The iacv/throttle body are 2 separtate items on both ve/vg engines,you do not have to buy a gasket to clean the t/b on a ve engine,just spray t/b cleaner into the t/b..
To the OP: Stay with your original plans with the iacv gasket,but you do not have to buy a t/b gasket if you are just going to clean it..![Smilie](https://maxima.org/forums/images/smilies/smile.gif)

I dont know if the iacv gasket part number for the vg is the same for everywhere but for Nissan of America it is 23785-21V140 so if anyone needs to replace it instead of giving your vin # to get it.
IACV gasket part number: 29785-21V140
IACV gasket part number: 29785-21V140
