A new pump is $40.00 what the!!!!
Where can I find this plug? We have checked with 3 different stores and they do not have the correct size.

I think it is a 3/4 cup plug. I will look later when I get to the shop.

It measures .650 dia X .375 depth....

21/32" cup plug. (.656")
Doorman do one in .320" depth, the depth difference is no issue.

**note these are available in reverse taper to make life easier

While you're in there, toss that flat tappet and stick a hydraulic roller in there.

Thank you CJ!
I would Mark but not my engine or money.

That should be correct. I was thinking .750 off memory.

Yes there are a few different sizes of plug, just have to measure and source.

We don't have an Advance Auto around here and they don't ship to our location.
We ended up order this
Free shipping so $8.41 delivered. I don't know why the link has a different price.

Beauty , at least you found something. What location are you in?

Washington State in the little town of Wenatchee. The funny thing is the local parts shop show that is a discontinued item.
Thanks again.

No probs, hopefully you get this sorted now.
I just looked at Wenatchee on google maps, it looks lime a fairly small and remote place , nice to be away from the big cities. Im south of Adelaide in South Australia, tiny city really but still too busy for my liking!

Well crap, you're just up the road from me...kinda. You couldn't find one of those in Yakima or the Tri-Cities?

Not worth the 2 hour drive....we'll see if it shows up today. The good thing is we aren't in a big hurry so whats a day or two?

Well, here is the rest of the story...... got the engine all back together and broke it in @ 2200-2500 rpms for 30 min.
About 10 minutes into break in the clatter started up again but we finished it as oil pressure and temp were fine.
Pulled both valve covers and discovered at least two of the rocker arm adj nuts were backed off.
We are replacing all of them with new just to be sure we have our bases covered.
I'm sure now this was the initial problem but live and learn! I'm not to upset by this because the engine is much cleaner inside
and it's cheap insurance to have double checked everything.
Thanks to all that chimed in much appreciated!
