[brider]

I did a search, I promise, nothing that exactly answered my question:

F engine, runs great, oil pressure low at idle, but nothing knocks or rattles, and I'm not tearing this one down until something drastic occurs.

But I get a big puff of smoke at start-up, which I understand to mean my valve guide seals are worn. My wife is not happy, and I kind of get embarassed myself when an admiring person in the Home Depot parking lot waits for me to leave, and I see him waving the smoke away from his face as I pull away.

Is there an agreed-upon additive that minimizes this effect? If not, just say so, and I'll stop complaining about it.
