What brand cam seals to use??

[jmpSHO2nd]

What company makes the best cam seals for our cars? I can't remember what I just used but one or maybe more are still leaking after my front 60k.

I have read that you should stay away from Felpro. I'm probably going to go with Nationals when I do mine.

Just did mine and the Fel-Pros SUCK!!

Went out and bought Nationals the next day. Fit much better and felt like a higher quality product.

^ This, but strike # 3 off the list completely for cam seals. I think their stuff is ok for other uses (valve cover gaskets, intake manifold gaskets, etc.)

What is the National cam seal part number?

I would stay away from the timkin ones too. They are metal around the outer edge and don't seem to seal very well. I put a small amount of rtv around the edge prior to installing them and my rear one still leaked.

I only use ford cam seals. shosource and shonut both sell them.

That is what I used in my engine rebuild. Zero leaks.

Koyo brand?

Has anyone tried Koyo seal ? RCM sold those awhile back as premium cam seals, guess they are made in Japan.

 

[boat]

Yes. And they suck. They are metal on the outside edge. Similar to the ones Jayro mentioned above. Within less than 1k miles they were leaking. Stay away.

I have ford OEM in mine, and 20,000 miles later, they are still good and not leaking.

They are also thinner than the rest.


I ALWAY'S coat the outer edge with RTV.

I ALWAY'S coat the outer edge with RTV.

Yep, I do this as well.

 

[itwonder]

I concur. The Ford and National seals seem to have fewest problems. Both require RTV around the outside rim.

The metal OD seals probably require anaerobic, reactive sealer like one uses to seal transmission case halves. To get this to work properly the sealing surace in the head or valve cover (or cae half) must be brain surgery clean and degreased . . . . .

The more modern design Windstar axle seals, which fit on the drivers side of an MTX, can be made to fit the passenger side of an MTX, and likely fit ATX, come with the red anaerobic sealant preapplied to the OD. But trans sealing is not the point of this thread . . .

The National 1213N seals have red anaerobic on the OD. I've never had one leak and I don't put RTV on them.
