Cam seal leak help please!!

[Mr.Fujiwara]

Ok guys so here is the deal,
I recently swapped out the head gasket to a trd one
and while i had everything off i figured i would swap
out the camshafts as well. So I purchased some tomei
264 cams and put everything back together and now I
have an oil leak from the crank seals that I did'nt have
before hand. So I purchased some new cam seals put the
proper sealant (UltraBlack RT4) let it dry for 48 hours with
out the valve covers on and it still leaks. So I got some
felpro cam seals did the same thing and still leaking!!!!
I have the proper amount of oil and everything is put on
and torqued down correctly according to the fsm (Factory Service Manual)
that I have any advice or tips would help thanks CLub4ag

I never use rtv sealer with cam or crank seals where the actual seal sits. They're designed to press in and seal. Sometimes when you put sealer it creates a slight gap or presses the seal too far in one direction. Get some more felpro ones, clean out all the old sealer and retorque it down with the new seals installed without the rtv sealer.

Never use rtv sealer, I use lubeb cam seal you can buy them any parts store.

The service manual calls for using a small amount of RTV or other sealant on the cam caps where they touch the head. If you didn't do that, I think you just found the source of your leak. Check the service manual and it tells you exactly how and where to apply it.

^^^correct!
Fujiwara..if any sealant is being used, it will be for the two forward cam caps only (head to cap mating surfaces). Very little sealant is needed for this..keep that seal & seat area clean & dry, then proceed as stated above

[Mr.Fujiwara]

I put the sealer under the cam caps and where the rubber can seal meets the head as the manual calls for and I'm still getting this leak I put som aviation sealant on it last night I'm going to let it sit for 24 hours and then crank her up thanks guys ill keep you guys posted on what happens next !!!

[Mr.Fujiwara]

Anyone nearby wanna' help out a fellow member?? I would've jump in & helped but ur not close man..sorry!

[RW Bliss]

Try using cam seals from the dealer... I've seen aftermarket seals leak over and over

[RW Bliss]

And make sure there are no score marks on cams from installation

[morgan]

What steps are you doing to instal them? First to last.

[oldeskewltoy]

0) Are you SURE the leak is from the cam seals?

1) inspect the camshafts for damage...

2) Are you using any thread sealant on the pulley mounting bolts? No? add a drop of medium(blue) thread locker to each bolt

[Mr.Fujiwara]

Thanks oldshchooltoy

I bought Oem cam seals
Used thread locker
Rt4 ultrablack after cleaning the surface off
Let it sit for 48 hours and the leak is gone

Post up a vid of that thing ripping once you get it dialed in. The only vids I could find of 4ag with poncams were just idling, not driving. I've been thinking of trying them on my stock redtop bigport and want to know how aggressive they are.

[Mr.Fujiwara]

It has so much more pull uphills and the power band
Is intense the idle is a bit more rough but nothing crazy
Ill post a vid up ASAP deuce cam

[Deuce Cam]

Nice, thanks!

So what went wrong before it finally went right?
Also RTV is excellent for filling gaps, like if you didn't use a cam cover gasket at all.
It is NFG for under the front cam cap, or any close tolerance machined surfaces, like between the oil seal and the corner that meets the cam cover gasket. It isn't even really good on that corner where the gasket pushes into but seals well because what gets squeezed out forms a nice bead inside & out.
