Throwing my motor back together and some guys put RTV on stuff that some don't. Just wanted your guys opinion. What gaskets really DON't need any or shouldn't have any?

 

I RTV everything except for oil pan, headers, valve covers and heads. Intake only gets it along front and back of block.

 

I used RTV spareingly on my EGR hose because i didn't have another gasket. Front and back of the intake manifold. I also put a dab in the corners of where the oilpan seal meets the timing cover and where i partially tore my oilpan seal Everywhere else i used conventional gaskets on CLEAN surfaces

People tend to think more is better and then it squirts out when you bolt stuff down and gets into your oil passages ect, don't do that

 

Ditto, except throttle body main gasket and I also use LOTS of Permatex Copper Hi temp sealant especially in the back of the intake around the oil pressure sensor bolt.

 

Forgot about TB gasket, no RTV there either.

 

Me three

 

I use ultra copper on my header gaskets

 

I agree except that I did use a small amount of RTV just to hold the oil pan gasket in place when I put the pan back on with the engine in the car. If your engine is out putting it on completely dry would be the way to go, providing everything is squeaky clean. Get the front or the back of this gasket off just a little and it will leak oil like you've forgot to put the oil drain plug back in.

 

I put the throttlebody gasket, waterpump, and rear end cover gaskets on dry.

 

I rtv'd dabs on all of my gaskets...

 

Your telling me you guys even put it on exhaust, head and intake gaskets???

 

I used a Little on the intake and tons on the front n back.. and a little on my exhuast gaskets too..

 

what about using spray on sealant on some of the gaskets? when i just did my intake manifold gaskets i used some copper spray on sealant because i heard you can have leaking sometimes between ports. i probably didnt have to worry about this and i'm sure this is more true about higher compression motors. however, i didnt see that it would hurt anything and i would rather be safe than sorry. just personal preference.

 

No gasket needs RTV, .... RTV (Ultra Copper) the front and back of the intake, and the header gaskets, put the rest on dry, you can copper coat (spray) the head gaskets ......JMHO

After being a engine builder for over 29 years we learned a lot about what to use and what not to use, again JMHO !

Many things don't even need a gasket, RTV works just fine, Notice that the factory is going to useing more RTV then in the past, I myself only use Ultra Gray or Ultra Copper, both work very well

The best advice anyone can give another doing any type of work with gaskets is, Use The Torque Specs Even For The Smallest Of Parts!!!!
