So, I'm posting this here because there doesn't seem to be an active u-body forum. I guess I'm not surprised. Who gets excited about minivans?! Plus, there's a lot of knowledgeable people on here.
Anyhow, I have a '98 Montana Transport with the 3400 V-6. It has developed a pretty bad oil leak that's slowly getting worse. Over 1 quart/3000 miles. I cleaned the engine bay and underside as best as I could to see where it was coming from. There's something that looks like a pipe plug in the oil filter adapter. This looks like the most likely source of my leak.
My question to someone who is familiar with this engine is: Is this just a NPT plug? If it's steel, can I just wrap it with some PTFE tape and run it back in? [Pic below]
It almost looks like that's where the pressure sensor would/could go.
I have no problem tearing in to my GP. If I break it, it can sit till I fix it again. But this turd is a different story. The wife needs this thing on a daily basis to haul the booger eaters around. Can't be without it!
