My rear cam plug is installed to a depth of 7/32". Is this going to be a problem? Is it too far in? My Helm's calls for a plug depth of 1/32".
Will my timing be messed up if I leave it at 7/32"? At this depth I don't get much rearward movement of the cam.

On a different note, I measured cam endplay between the cam gear and the keeper plate at .010. I did this correctly right?

Forgot to add - If this is too deep, is the diameter of the plug 2 7/64"?

This sucks. Engine assembly starts tomorrow. Father/son kind of thing. Wouldn't want a stupid cam plug to screw me over.

 

.010" of end play in the cam is fine. You measure that after the gear is bolted to it. The retainer plate, in effect, goes in the gap between the nose of the cam and the back of the cam gear.

The plug has nothing whatsoever to do with locating the cam. There's supposed to be a gap aof 1/8" or more between the back of the cam and the plug. The main thing you need to be concerned about, besides the cam just plain runing into it, is having it in so far that it covers up the drain hole behind there; if that hole is blocked, then oil pressure will build up behind the cam, and will surely blow the plug out.

But, if you've got it to within .010" of touching the back of the cam, then it's definitely in too far. You can't leave it like that.

Use the cam to force it back out, by bolting something across the front of the block and pressing on the cam, or by tapping on the cam with a block of wood. Then put a new one in, to the correct depth this time.

 

Thanks for the news. Just measured the rear gap to the rear plug and it's also .010. Guess I'll be pulling it out.
It is a 2 7/64" plug correct?

 

NM. I forgot the size is stamped in the plug.

Thanks for the help.
