Stupid Question About Throttle Bodies Options

[JohnnyWadd]

Okay, I feel like a dumbass for asking this, but you don't put gasket sealant on throttle bodies, right?! I'm already sure you don't, but I'm just looking for a little validation.

Thanks guys. I'm a dipshit!!

I put on a real thin layer so that it will seal. I'm probly wrong for doing this but it works.

[asiankid91]

well i had boost leaking out of my throttle bodie i put gasket sealant on mine

[AWD DSM 1]

I usually put a paper thin layer on, just to make sure it sticks. Defiantely don't goop it on thick.

No, I never have...Don't need it.
Well except to temporarily fix a small rip in the TB gasket until I got a new one.

Werd, only for a temporary use, if you get that stuff sucked into your intake, bye bye internals.

Would a little chunk of RTV really do damage to the internals? Seems a little far-fetched to me, but I've only been wrong about 513,154,148,695 times before. I don't forsee any problem with it, however, I've always gone the $2.50 OEM gasket route.

The chances of RTV causing a huge problem are probably slim, but anything that can make your valves hange open can be pretty ugly on a DSM!

I've had a few friends that have blown some internals from gasket maker (rtv) It was a very pretty site is you ask me

I didn't think about it getting wedged in a valve. I guess I just figured since it was soft and flexible, it wouldn't damage anything. I can see how that would make quite the bad day for someone.

What internals where damaged...and how was it attributed to the RTV???

I can't believe some rubber in the intake/exhaust track would cause any real damage. I would think that a couple hundred pounds of seat pressure would pound the snot of it before it hung a valve.

Any RTV that made it into the oil should get filtered out by the oil pickup and oil filter before it got back through the engine.

Mainly a few bent valves here and there. Mind you, it was quite a bit of RTV that was actually used, so I'm not sure if just a think layer will be a problem. I was just adding to the fact that a lot is WAY too much

I use RTV on just about everything. I get the light blue silicone that dries quick. I let it cure almost completely though before I put it on. And I put it on in very thin amounts. but ive never had a problem on any of my cars.

[awd4kicks]

When I first started working on cars...EVERYTHING got RTV. I figured better safe than sorry, right. On top of that, if some is good....more is better.

Well over the years I learned my lesson quite a few times. And by the advice of a friend at the time 'Just use enough RTV to hold the gasket in place if you need. Otherwise let the gasket do the job it was designed for.' My success stopping leaks has increased incredibly using this advice. I hardly use any except when water passages are concerned or your making a gasket from RTV like on our oil pans.

Just some info that might be helpful in this discussion.

[natedogg]

^^^Agreed.

I learned this the hard way as well. (Friggin oil pump gasket)

[JohnnyWadd]

I got mixed reviews on this one, guys. Since there was no consensus, I just decided to go without for the time being. I figure if I end up with a leak, I can always come back later and coat the gasket with some copper spray.

By the way, I never intended at any time to not replace the gasket with a new one from the dealer. I'm not that big of an idiot. I was just curious as to whether it was a good or bad idea to put any sort of sealant on it. Some people said I should, and to use RTV. Some said to use copper spray (I love that stuff!!). Some said to use a new gasket only, that sealant could damage your o2 sensor or maybe even the valve train.

I haven't leak tested it yet, but I'm going to very soon. Not for a few days, though. It's friggin' cold here. It's not supposed to get over 15* for the next three days. The leak test will have to wait.

Thanks for the responses, fellas!

Seems like you got a complete consensus on your decision: don't use it!
