VF3's Leaking, Need Advice

[Driggs]

I can't get my VF3's to seal. I'm loosing lots of air on my leak down test. I had the VF3 gasket, then put a stock gasket on the other side and it helped but still leaking. I saw where someone said to run 4 gaskets. What's up with that and will that stop the leak and if not, what do you suggest? Also, it doesn’t look like the stock gaskets fit the VF3's intake manifold side so is that a special order?

I run high-temp black silicone on both sides of my reeds and don't a problem.

So you don't run any paper gasket? Just the silicone?

Run gaskets and sealer. You just need a small bead around both sides of the gasket wait a little bit for it to set like a couple hrs or over night then test it out.

Are you running gaskets on both sides of the reed?

No, I did not use gaskets. I let it cure for 24 hrs.

lol, i mean that it's ghetto that you have to do that with vforce........especially because rtv is not compatible with fuels/solvents. they should be made better

i run the seals that come with the reeds along with using gasket sealer......the copper spray on crap made by permatex.....works great as far as im concerned..

[dirtydownunder]

make shaw both surface's are clean and smooth, the gaskets should be all you need, tho i use a tiny bit of sealant (Permatex number3).

and yes, gasket for each side of the reed.

[VegasJeff]

I use the gaskets and a thin layer of the yamabond sealer for the casses.

I've used both Permatex Black and Permatex motoseal on the reed cages before with no leaks before (no gaskets).

 

Just be sure you let it cure before overnight before you run the motor.

Lol. You use a gasket on each side of the reed, and yamabond, super grey etc etc. I've never had a problem just always have used that combo.
