To bypass or not to bypass...

Thanks Mark - yes, I think tapping it is out of the question at this point. Not really too keen on pulling the whole shortblock apart again to tap the thing. I have seen plenty of others on here who have it blocked with a freeze plug. (I think I recall reading about someone who pulled apart a shortblock that had it blocked with a coin!) I think using some Loctite and staking it should keep it from going anywhere. Not much more than that holding the factory bypass in place. I might give Eddie a call later this morning to see if he might have a part number and a source for the plugs he is using. The biggest pain might be finding someone to turn it down shorter for me in a lathe. Still trying to picture how you would hold onto something so thin to run it up against a belt sander to sand down the depth, but I don't pretend to be a machinist!

Just take a 1" paddle bit and drill a shallow hole in a board the depth you want the freeze plug to be and use that to hold the freeze plug against a belt sander.

I just measured the plugs. The 20mm plug has a diameter of .800 and the 13/16" is .815. You can see that there is quite a bit of difference. It just so happens that the 13/16" plugs that I have are deeper than the 20mm. They are offered in different depths but my supplier only had these.
Here are a few pics of them side by side. The 20mm is on the right. I also attached a pic of one that is plugged with a 1/2" NPT pipe plug. That doesn't sound like an option for you if the shortblock is already assembled.
Send me your address and I will be glad to send you a plug. I'll cut it down first so all you will have to do is drive it in.

Got your PM Budman. I cut a plug down today and have it ready to ship to you. I'll send it out tomorrow.
Let me know if you need anything else or if I can help in any way.

cp, is yours a Gen V / VI? If it is a Mk IV, the bypass is in the filter adapter that mounts on the block. If it is Gen V/VI and you have not at least installed the 30 lb bypass in the block, then yes, you are definitely going to have problems and need to address it.
