Re: Not a great start. Need some advice!

Lifters have to mate with the cam which causes a lot of initial wear on both. Once they are happy with each other they last a long time. If you replace the lifters they both have to wear together and the cam has already had the wear from the previous break in so now it has double wear. That can only happen so much before the cam is ruined.

I have seen, but not used, valve covers that were drilled with 6 holes to access the rocker nuts. That should keep down more of the oil spray.

As to cam wear, Joel says what I was trying to say. This initial wear in is why the 2500 rpm initial start with a new cam, to make sure there is oil flying everywhere, washing the debris to the pan!

Rick and I just made 3 of them. Going to mount 2 on the Mouse House 110 engine this week to do valve lifter adjustments. I have 2 more covers only good enough to make adjustment covers out of. They will be done hopefully in time for Springfest Helen.

Would like to know where he got the plugs from.

Yes we would Al. I have and have seen covers with holes but have never seen plugs. Brilliant.

Talking to Jim D right now. He used 60lb cup magnets from Home Depot.

We did try the 1/3 cover and had difficulty getting the 5/8" socket on and off on some rocker nuts. These covers are trimmed along the ridge line down from the centerline of the cover. Our covers were drilled as described below for the 5/8" socket (0.840 dia) and some 1 1/8 holes we drilled were below the ridge line. So the magnets will slow down most of the oil that attempts to escape. We might wind up using aluminum tape applied on a clean cover. Pulled down for adjustment and pushed up for closure. Doesn't have to stick, just be close enough to dribble oil that gets on it back into the cover.

MODIFICATION OF VALVE COVER
We bolted up our covers on a removed head and turned it upside down. Then we dropped a 1/2 drill bit down each lower mount hole in turn and tapped the drill bit with a punch and hammer. We noted that the line of bumps in the cover were not in line. Since we had no slop in the drill bit to the hole, it only confirms some of the lower mount holes are lower on the head than others. Thus the reason for some difficulty on some rocker nuts and not others. Covers were drilled with 1 1/8" hole saw for the 5/8" socket (0.840 dia) in a drill press. 1/8 holes were drilled first for pilot holes.

My 1/3 cover was not cut evenly and I also initially had trouble fitting the socket. I used a grinder to even it out. It would not be as much of a problem if the oil just dribbled, but the push rods have 2 holes at the valve end. The first hole is on the ball face to lube the rocker face. The second hole is on the side if the pushrod which rotates while it's working. That second hole squirts oil EVERYWHERE! Works great but as I said earlier you get little geysers once in awhile. Kinda like changing a daiper on a baby boy smiling smiley

I suspect the cam will be okay in my case as there was no discernible wear on the face of the old lifters. In hindsight they were probably okay to use.

The squirt is a good thing, some of them barely dribble.

You ought to see the squirt when the oil pressure regulator is stuck! DO O-ring job, adjust valves, stop and free up regulator slug!grinning smiley

No wonder people like the static method....thumbs up
