NO Omix gears!

I recommend MSD 8005 and 8007. I use them. OR - pony up for a matched set from Bulltear.

no & NO

You can not Jb weld the cover. I have never used OMIX & got talked out of them a while back. I have no proof they are bad But I'm not finding out.
I'm using MSD gears.

You really need to find out what caused it. I am seeing nothing but speculation as to what happened no facts. I twould be very interesting if the cam ger is in tact.

If you can't make it better why waste your time. No use repeating the orignal mistakes. I'm to old to push it that's why.

Same here, I am even missing a dowel on the 74 for about 150Kmiles, and no distributor gasket, even swaped an HEI from another wagoneer, about 40Kmiles ago.

I needed a timing cover this past summer. Went to the wrecking yard and found one for $ 60. Can't beat OE.

I had the same thing happen to me a few years ago, actually bought the timing cover - a Crown part - locally here in Oz from one of the Jeep parts suppliers. (They have shut their doors now.)

I read about the matched gears and the timing covers from Bulltear. In the end I got an OEM one from an old guy here in Oz that deals in Rambler stuff. He modifies the cover and it has stainless liners for the water surfaces.

Haven't had any issues since.

Well I have a set of Bulltear gears on order, going to install them and the old cover, check how the distributor fits and then the new cover and do the same, hopefully all will go well. There has to be somthing to make it eat the gears that fast.

Pretty sure all the timing covers (Bulltear, BJ's ...) all start life in the same place. Bulltear checks them for the correct dowel pin to dizzy hole relationship, and returns the ones that don't make the cut.
I don't think any other vendor checks the covers.
OE is the way to go if you can, mix and match and it all worked and played
nice together, the aftermarket is a crap shoot, with cam gears, cams, dizzy gears, front covers, timing gears ... have all had reported miss-matches that end up eating
the cam and dizzy gears, any one of the above can and will leave you sitting on the side of the road if wrong.
All the OE stuff swapped around just fine, but throw one bad part in the mix and you are hosed.

When you replaced your timing cover did you also install a new timing set? If you did you may want to verify your oil passage from the cam (backside of cam timing chain sprocket) to the cam gear that oils the distributor gear.

In fact, a quick check of everything before you pull your timing cover off, would be to remove your fuel pump and distributor, and then prime the oil pump while you manually rotate the engine to verify you have oil coming off your cam gear. You can look through the fuel pump opening on the timing cover to verify oil is dripping off the cam gear.

I did replace the timing set, I looked at both old and new and the oil passages seem to match. When I get it back together I will prime it and check for oil on the gears. The old cover was replaced by the PO so I don't know if it was an oem or aftermarket but it had almost 50k on it since then.

I used the omix gear set. I bought it back in 08 and they're still in the engine doin what they're supposed to, When I did my cam swap the gears looked just as good as when I got them. I also bought a bjs timing cover. The only issue I had with it was in the oil filter adapter not the cover itself. So maybe I'm the only one but, I don't see any issue with using a bjs timing cover.

So, would a good rule thumb be to run it a few hours and pull the dist to check the gears for wear?

I've never seen a bad Omix set I know of a set on a J120 thathas 80k on them. It could be Chinafobia. I decided not to find out.

A few hours may be too much, a few hand turn will reveal abnormal pattern, and said, match the oiling holes to their corresponding windows.

What brand timing set did you use. Also are you familiar with the problems with the oil slot on the back of the cam timing gear not lining up with the oil hole in the cam, or the slot being too long?

There are plenty of good posts on this issue like this one:

I used a standard non roller timing set from Oreilly auto, I checked the slot on the back, its the same length and position, just shape different, old one looks like a milled recess and the other looks like a hollow ground grove. I thought about using a dremmel and deepening the grove but i didn't. It's not any longer than the old one. The old and new cam gear each have 6 oil holes in it. Old to new I didn't see anything different.

danjohnson67...sounds like you are on the right track with knowing what to check on the timing gears. Before I jump on the bad timing cover bandwagon, I have to ask, "Did you replace your distributor when you replaced your timing cover?"

Nope. I replaced timing chain set, timing cover and water pump, everything else was left as it was. The teeth had little wear, nothing that looked even clost to needing replacing and I had already heard the horror stories about changing the gears and them getting eaten up...go figure Murphy seems to love me, I had all 3 vehicles with some sort of issue last week
