dublin14 Posted December 3, 2011 Author Report Share Posted December 3, 2011 When you vent the cam cover, and run high boost/rpms, the volume of oil that will leave the cyl head with the vapor is quite impressive. If you don't provide a drain back, you will fill any (normal sized) catch can on a single WOT run. This way, it all goes back where you want it, and only the vapor gets vented out or recirc, depending on your setup I have to check that soon. It was one of the parts I didnt install. I had to change the cam seals last night, both were leaking, and the I end up being 180 out after install and the car would start, PITA, but its done.

lookforjoe Posted December 3, 2011 Report Share Posted December 3, 2011 ^ I always have to check the manual/alldata for the cam setting slots (if the gears are removed) - I routinely forget which one is up & which is down . If you start with the motor set at the factory timing markings, it should be straightforward, though. Link to comment Share on other sites More sharing options...

lookforjoe Posted December 4, 2011 Report Share Posted December 4, 2011 Seals leaked again. Not sure why. Front or rear? What are you using to insert/seat the seals? Did you clean up the cams with crocus cloth/scotchbrite pad to ensure the seal seat is spotless? Did you grease the inner seal lip? Link to comment Share on other sites More sharing options...

The seals I pushed in by hand and then pushed with a flat head evenly around the seal. Cams are spotless, but I didnt use grease for the inner lip. Third set going in and I'll grease up the inner lip and maybe some RTV around the seal edge. I also pushed the seals right up against the cam. Some say flush with the outside surface of the head, and some say push them right in. I have done it both ways now. Link to comment Share on other sites More sharing options...
lookforjoe Posted December 5, 2011 Report Share Posted December 5, 2011 Pushed in with a flat head??? As in Screwdriver??? Dude, use a socket or a piece of PVC pipe. It doesn't take much to deform the seal body, distort the inner lip, or damage the spring that actually keeps the seal tight against the cam. If it's still leaking, you need to change your installation method. Link to comment Share on other sites More sharing options...

If it's still leaking, you need to change your installation method. The seals were pushed in with pipe the first time, and they leaked. I pushed the seals in the second time with my fingers almost all the way, and the flathead was just a nudge to make it even all the around, so I really doubt that was the key issue. But I will go back to the pipe method and try this again. Link to comment Share on other sites More sharing options...
