No hassle, just a question.. If condensate builds up due to not allowing temperature to reach operating temp, would not the condensate be found at the top of the oil sump, not at the low point or drain?
It's likely my terminology problem, but I would have thought that drilling a pilot hole in the drain and using an "easy-out" would have been the path I followed.
TIA
The water will be @ the bottom. Have you ever had a head gasket leak? Pull the dipstick and the choc milk will be on the tip of the stick. Oil is lighter than water because water is more dense & there's more molecules of water in a gal than a gal of oil.
If it's corroded bad enough to round off the plug I doubt an easy out will get it done. Rather than make a bad situation worse or spending lots of cash I would extract as much as possible and call it good until you want to spend the money. Just remember when you run it every so often run it till it gets good and warmed up. Just my thoughts.
BTW the threads are corroded due to condensation and disimilar metals. Alum pan & steel plug. There's probably not enough condensation in there to hurt the eng.
Good luck and keep us posted.
