And here's the little bugger*, aka stock threaded galley plug.

*I have used other words not fit for a family 914 website.

Even while unscrewing the plug, the leak is obvious, with oil-wet threads and no solid sealant.

Is that a crack running under the plug? Its appears like it has something on it right below the plug? I hope and pray I am wrong. (IMG:style_emoticons/default/beerchug.gif)

Not a crack (I hope!) but a surface scratch and/or a casting mark.

OK, I decided to try sealing the plug today. First I made sure it was as clean as possible, and without any problems with threads.

I reverted to the sealant that worked the first time with this plug.

Plug installed, along with the engine mount and cross bar. I plan to let this sit for 24-48 hours, and then run the engine and check for leaks before I put and ductwork and other stuff back together.

Steel plug/aluminum case. I have seen this debate in the past ......

Fingers crossed, hope you got it this time. I think many of us are chasing a leak in this area, but I for one just leave it. Too many fish frying

In the hot oil?

Speaking of hot oil, I ran the motor up to temp and shut it off. No visible leak yet, but I will wait to see after it cools off.

Just like last time, the morning after was not good news. Still looks like the galley plug is leaking. I will have to remove the cross bar again to be sure. That means dumping another oil fill with 0 miles.

Have you considered trying to find an Aluminum plug? The CTE will match the case material so you should have less gapping when the case gets warm. I don't know what thread size this is, but there are some aluminum galley plug kits available for VW motors.

You could also try thread tape instead of (or in addition to) the sealant you've been using. This stuff (available at big box home stores) will stand up to almost all fluids.

I admire your determination and appreciate you sharing your trials and tribulations!

@bkrantz

man that sucks! wow, i agree that maybe different plug will fix this?
- the rest of it is soo clean! i wrapped my cables just like yours, i am also fighting a leak on my new 2.1 motor and i think its seeping from the head-cylinder interface!! verified my new oil cooler seals and pump seal and galley plugs are dry this time along with the new RMS no leaks but man i know how frustrating it is.

I have a question, what are you using for modern EFI
I control, is it the Holley system?

The more I look at the pics (not just this one) the more it looks like a crack repair......that has failed. Probably over torqued at some point in engine's past? otherwise strange spot for a crack.
