Cam Seals

[brentos]

Hey guys just a quick one.

Which way do the cam seals go in?

Like this: 

Or like this: 

The reason I ask is I just installed my 264 cams and didn't take note of which way they were facing when I removed them and after putting it all back together had a nasty oil leak from both seals.

I have since got replacement seals and just want to make sure I do everything correct this time. Also I believe I can put oil on the inside of the seals and gasket goo on the outside of the seals?

Thanks

Also the replacement seals seem to have a little spring going around the inside of it :

The first. The second picture should be removed from the annals of history.

You can and should apply some light grease to the inner surface of the seal that runs on the cam; factory ones come with it. Silicone should not be required on the outside of the cam seal but I have heard of it being done.

I've circled the spots where it can be a good idea to put a little sealant. The corners are always the leakiest.

I should point out, that this is more true of the outside of the metal, where the other gasket runs, than it is true of the cam seal itself. I'm talking about a mere smear on the inside corner for the truly paranoid.

The spring around the back of a seal should always face the oil side....golden rule.  There could be exceptions, I haven't found one yet.
