The blue threaded plug in the attached picture may leak or weep Why?
I have the front and the rear galley plugs seeping now the machine shop that tapped and plugged the galleys did not seal them properly.

So I need to know what would be the cons of having a weeping internal oil galley plug?

My guess is lower oil pressure?

Thanks in advance?

I'd put Loctite on those plugs which should help seal it.

Loctite is not designed to be a sealant. Use teflon tape :-)

Why?

The flywheel bolt holes on the crankshafts of old Ford Mustangs go strait through and into the crankcase (wierd, i know... and yes i know a Porsche is not a Ford). You're supposed to use a sealing compound (or teflon tape) to seal it up, if you use locktite it could crack and leak.

Loctite - Stop bolts from backing out
Teflon Tape - Seal threads

Oh, if you already have it all together and in... i guess you'll find out...

I wish I would have known that when I built my last small block Ford. Whelp, no leaks yet...

There is a product on the market, gas station supply houses - maybe some auto parts stores called Gasoila. It forms a semi hard sealing surface and should fit your need just fine.

If the blue plug leaked, you might experience lower pressure.

Did you buy that shortblock out of New York or is that one you did yourself?

Thanks for the recommendation...Ahhh no did not buy block this from someone in NY however being slightly stupid I did have someone do the work for for me.

If the front one leaks (near water pump) I risk mixing coolant with oil correct?
If the plug at the back of the block leaks I risk just a oil leak yes? no coolant oil contamination there correct? Internal plug if I leave it to seep I risk loss of oil pressure correct?

thanks again

I personally like tapping and threading the one under #1 cylinder. Talk about a loss of oil pressure and hard to track down - and it's happened too and it's found when you pull the pan off to check for a cracked pick up.

No on the mixing, the front one, remember the water pump ear almost fits over that perfect and has nothing to do with circulating water. If the plugs leaked, you'd have a leak, albeit the one under #1 would at least return the oil to the pan and not on the garage floor . If they blew, you'd loose oil pressure whether it was threaded or just plugs.

I use the Gasoila on the oil cooler lines, to the cooler, and fuel lines; so far it has not failed me yet nor the engines we've used it on. Next time you fill up, look at the back end of the fuel nozzle, that little white/gray substance on the threads is it.
