trouble removing plenum

[MattiasJacobs]

why not clean the throttle bodies?

Forgot to mention: If you want every last bit of paint off that plenum before repaint without taking it in for Sandblasting. Spray gasket remover on it!

^^^I've heard this too. I cleaned mine, I do have a high idle but I've also been told by good sources that it shouldn't cause problems. My suggestion... give 'em a wipe and then leave 'em the eff alone.

I've heard varsol doesn't hurt it.

thanks for the info...so that little ridge is still there luckily I didnt use anything extreme to get it off....will I be ok or think I should still go ahead and get some of the sealant

just use testors model enamel if youre skeptical. Ive heard it works awesome from the aussie guys

Why isn't this sealant mentioned anywhere in the Service Manual? I cleaned my throttle bodies thoroughly with brake clean during my rebuild. Are there any other issues other than a high idle? I am NOT pulling the intake side off after all that I have been through this year with the rebuild.

I've held my throttle bodies up to the sun and I can see a couple spots where a tiny bit of light shines through....is this going to tamper with having idle issues or a high idle? Want to know befor I pit it all together and find out the hard way

This is one of those damn problems to which there seems to be no precise answer. There are several issues that will cause a high idle with the RB26.
-Vacuum leak.
-Improperly adjusted AAC/idle.
-Malfunctioning (dirty) AAC or IACV.
-TPS out of adjustment.
-"POSSIBLY" cleaning the sealant off of the throttle bodies.
The last one I spoke to two guys at my local Nissan dealer (over 50 years w/Nissan between the two of them) and they haven't seen anything like that sealant and didn't believe this could cause I high idle.

There is a test to verify if the IACV is working properly but it has to be removed and that is a BIG pain unless you already have the I/M off.
