I thought I read that bulltear was the same cover but they checked it over to make sure they were good?

What I gather (from here?) is that BullTear has a jig that tests for alignment. They reject the out-of-spec parts. See if you can contact them before you buy - they have a reputation for not responding.

Personally I only trust oem used covers.
They can be refurbed.
I've never seen anyone have a problem with eating cam/distributor gears.
Many have had issues with new aftermarket covers eating gears, poor fit, leaks.

Do you still have your stock one? If so, why don't you want to use it?
This post tells you what to look for in the after market timing covers.

I had a Bulltear cover on my last 360, and within 500 miles I had to take it off to replace a distributor gear.
I also thought that BT had better Timing Covers?
The reason for the new cover is that my old one had a coolant leak. Of course rick, ristow, and tony all said to rebuild my old cover but I did not listen, and had good luck in the past with BT.


SC397 & Ristow have done stellar writeups on rebuilding your TC.


Here is the BT cover I have.


Looks pretty huh?

After market

I purchased a after market cover and it was junk so put it on the shelf 200.00 bucks down the drain .

No, it doesn't look pretty to me.. I (and Matt Bulltear) hate that giant chamfer right where it don't belong around the inside of the oil pump cavity.

Give me a greasy grimy one from the 60's or '70's any day.

My builder is not willing to guarantee oil pump. He sees a bit of wear grooves. Don't know his source for cover but he quoted me $380. thx for site. what is clearance of gears to sidewall of pump?

[Curly5759]

I bought a BJ's cover hoping to improve my hot oil psi @ idle. New cover and gears and mid-plate. I measures side clearance and plastigaged the new cover with gears. I got the same measurements I had on the old cover. Same Oil Psi as well.



The cover fit fine and the leak from the oil pump bolts has stopped with the new cover. My hot oil psi @idle is just under 10 psi, measured with an aftermarket electric gauge and verified with a mechanical gauge. No noise, I just don't like it. I've bumped the idle a bit to compensate.

oljeep.com has manuals all oil pump info specs. are in there.

I would encourage you gather info. and bring it to your builder.
Specifically the timing cover refurb. threads by Ristow & SC/397.
Also be a good idea to do the same with timing chain gear issues/resolutions by SC/397.

There is more to check than just slapping a $380 cover on it.

As said by several I'd stick with your original or a used OEM.

Any timing cover should be checked for oil pump shaft and distributor gear alignment along with oil pump gear clearance checks.

I use gear marking compound on the distributor gear to see the mesh pattern just like checking the pattern on a ring and pinion gear set. Distributors can be shimmed up and down as needed to correct the mesh.

90% of AMC distributor gear failure is caused by improper machining of the oil passaged in the camshaft driven sprocket. Those should always be checked too.

Do those things and AMC distributor gears last longer than on most of the engines made by other manufacturers of the times.
