gasketing question

[kkmcgregor]

So I'm going to regasket everything that involves airflow essentially. (Bov flange, throttle body and shaft seals, intake mani, exhaust mani, turbo gasket, and wastegate flange)
I've been reading and it seems some of these can be just rtv.
So question is can I use rtv for throttle body, bov, and ??? Also what rtv should I use.
P.S. reason for this is everything leaks.

No one here will tell you RTV is a good idea where a gasket use to go. With that said you can do what you want, but know that wasn't how it was engineered.

Ok cool thanks I really wasn't sure.

RTV is a cancer in my opinion. The only place that it should be used is on an oil pan. Gaskets are cheap and much cleaner.

I mean RTV is good to cover up some of the imperfections that you make by scraping the old gasket material off with a razor. Not every one has a rotary tool with those roloc pads to sand most of that junk off..

OEM gaskets from JNZ or RTMRacing. Pick your side of the border.
Two best suppliers for the Mitsubishi breed of parts. Back bone of the communities on either side of the border really.

Most OEM gaskets are update and contain where applicable, the little silicone rings imbedded on their top and or back facing surfaces, to make up for surface irregularities.

The BOV and IC-to-turbo-inlet gaskets are now metal single layer crush style. If there are non-metallic versions still in stock somewhere, pick that if you have surface issues that can't readily be corrected, but even then a file or prep disc treatment are in order.

As Jeverts stated, save RTV for oil pans or any application where RTV or anerobic sealers are called for (transmission case halves, differential covers, transfer cases, etc etc).
