rtv on gaskets? i dont know

[Big B]

i replaced my turbo and i reused all the old gaskets. i just now got a turbo gasket set because my oil return pipe was leaking. someone told me to put something like silver rtv on the gasket for the oil return pipe or something. should i use that? if not what is a good sealent to use and should i use it on all the gaskets?

You do not need to use sealant on any metal on metal exhaust gaskets.

I would use RTV black on the drain if you HAVE to.

ok cool thanks. ill put the gaskets on and if the oil retun pipe still leaks ill try thhe rtv black

I've always used ultra grey. It's never let me down. Where is it leaking on the drain?
I use copper spray on exhaust gaskets, head gasket, front case, OFH, intake manifold.

Its leaking where the pipe meets the oil pan

 

[Maverick4g63]

It may be leaking by the actual threads of the bolts that hold the oil return fitting to the pan. I have used thread sealant and it seems to have helped.

 

[nitroazz]

Use a thread sealant on the bolts. Did you use new crush washers when you installed it?

I recommend RTV Orange. I have had it on my cars for the longest time and I haven't had it leak or break yet. It gets mighty cold in the winter here and moderately warm in the summer and I daily driving it all year long.

i agree, thread sealant and new washers.

as for rtv its all personal preference. for my shops i try to buy the higher temp sealants, usually red, it stands up to the underhood temps of my 18 wheelers.

I use RTV or "Right Stuff" on the fiber gaskets such as the turbo oil drain gaskets and intake manifold gaskets. I copper spray the heck out of all metal gaskets, like MLS head gaskets and exhaust gaskets.

When working with DSMs...

RTV "Right Stuff" is a must!!!

Use it all the time on gaskets for waterpump, oil pan, oil pump, valve cover, rear main, oil filter housing

Never any leaks

Personally I dont use any sealers unless i absolutely have to. Just make sure you clean the surface properly before install.

And I know there are different trains of thought on this, but using spray sealer on MLS Head gaskets is never a good idea because of the vitron coating on the HG. That is there to seal it, not the spray. they spray softens the coating and breaks it down. Infact most of the manufacturers will tell you not to use it on their HG's. It may help if you are not taking all the steps to ensure a properly prep'd engine, but its still not good. MLS HG's require a very smooth finish to seal properly, and most people dont machine the block with the head, and thus the reason their MLS head gaskets fail and they spray copper them. It swells the coating and causes it to seal (until the coating hardens again that is). And then they have to replace the gasket and scream that company is garbage. Its more often the builder than the product if used properly.

You need to replace the crush washers and bolts in order to eliminate the leak. I have tried it many ways and that was the only one that worked. Mach V Motorsports sells them here

thanks alot guys. i changed it and i didnt use any rtv but i did get new bolts and the leak has STOPPED. so thanks evveryone

 

[DSMDEMON93]

For future referance, make sure you always thoroughly clean any gasket surface before you place a gasket down, and lay some RTV compound, otherwise, contamination from oil and crud compromise any possibilites of a proper and perfect seal.

Where did you get the bolts? Thats it? Just bolts? I'm also having this problem but never fixed it.... I noticed yesterday my oil was low, under the 1st notch on the dipstick and I think my oil pan is leaking a little as well

 

[kmarttalon]

i think thread sealant and new bolts, I also use copper spray on my head gaskets

just for any home improvment store. just make sure its the right size . but mines was leaking from the oil return pipe. if yours is leaking that much where you have no oil you probably have a different kind of leak. did you change the oil recently?
