R/S Crank Seal Air Leak


Recommended Posts

So, it was time to repair my shifting problem.  After repairing that issue and reassembly of the motor I tried doing a leak down test and the air is coming out the R/S crank seal as quick as it is being applied to the intake port.  I have double checked and the seal is installed correctly and I can not figure out why it is leaking?  I have looked through my Clymer manual and looked on line at parts diagrams to see if I am missing something and cannot see what it is???  Any help, suggestions or guidance would be greatly appreciated.  Thanks.

Unfortunately I don't know everything and I do believe in stupid questions get stupid answers, so thanks for pointing me in the correct direction.  You were correct on the key way, but you already knew that.  I only have to be told things once so I will remember this in the future.   I now just have a very slow leak to find.

Thanks.

Sealant was applied to the key. The slow leak is coming from the top right side of the billet intake manifold.  the weight of the carb and air filter has pulled the rubber away from the metal just enough to brake the seal.  I put some RTV silicone on the surface and let set over night.

The thing about billet intakes is... they suck on so many levels.
That being said, my opinion is they require a specific method to install.  You can't just torque the cyls down because the one piece intake needs a flat common plane to mate across the 2 cylinders.
The following order of operations has worked for me and aligned the cyls to the billet intake.

Install cylinders equally tight, just a few ft/lbs.
Mount the 1 piece intake and tighten half way to torque spec.
Next, final spec torque the cyls.

Finally, spec torque the intakes.

I recommend ditching the blingy billet intake and picking up a pair of separate UPP intakes.... that eliminates alignment issues == but hey, that's just my opinion!
Good luck on your repair.

Is this rubber that was bonded to the metal, but is now leaking ?
