Did a cam/belt swap a while back and noticed the factory cam seals were leaking, so I replaced. Now doing a head upgrade and notice oil seepage again at the lower passenger side of block, just like before when the cam seals were leaking. I used a socket that fit the seal diameter to push into the cap after cam install. Is it possible I pushed in to far to cause a seal to leak? I read in the SRTForums were someone started the seal and then let the cam gear push it in to the correct depth has the tighten the cam bolt. Any ideas would be appreciated.

thanks

There should be a lip on the inside to prevent the seal from going too deep. I fear letting the cam gear push the seal in only as far as the cam gear goes could lead to early failure due to the cam sprocket running against the front of the seal. This is one of those cases where wiping a thin film of silicone sealer around the outside edge of the cam seal may be needed even though they don't normally leak, there have been a few cases. Ensure there isn't any knicks or scratches on the front of the cam seal surface and that the front cap isn't loose or any dirt within the two surfaces which would prevent if from clamping down against the outside properly.

Yea, I'm thinking the same thing.

I'll try this tool and see what happens. Would like to get this fixed right. Cams were new and have no wear on the seal journal.

thanks

Got to the seals on Sunday, exhaust cam seal dry and intake cam seal wet on outside edge that seals to cam cap. Not a bad leak just slow seepage. I'll try a little RTV wiped around the seal edge on the install. I'm doing a head swap so there is a big unknown with that.
