Well...my super de duper modified for John instructions say that after changing the supercharger to a newer style, running lean enough to have an AFC it is expected that you will have the potential for issues. I'm also wondering.. you are EGRless right?

I'm betting when I get my engine out, I've got bad ring(*) somewhere. It'* been burning oil longer than it'* been making metal specs.

So yes, ALMOST unheard of... till you heard it from me.
LMAO... Ain't that the truth

Not EGRless. Every L67 got an EGR. But, yeah, I've thought that myself. There could be something about my particular combo (that I haven't seen anyone else with) could slowly kill an engine, maybe. Or I got something in my oil once, or... who knows.

Good news .. you will soon find the bolt you lost during the supercharger/manifold conversion a couple years back.

Your'* is an odd case, however it'* not the first time we've seen or heard of bearings going bad. You are merely one of the very few.

It'* here. Now, should I just put it in and let it break in before I head swap? Or should I get the head work done real quick and swap the heads before I put it in?

Oil pressure update: After months of running 15w40 with "ok" pressure and showing no signs of getting lower... today it decides to drop to 10 psi at idle in gear. So low the CE light came on! I didn't let it idle like that for more than a moment before giving it a little gas to bring pressure up. Next stop light, it dropped just as low.

Ah yes.. The Few...The Proud....The spun bearings on a 3800.

I belong to the bad bearing club.......Semper Fi.

John, were you expecting 92 heads? Cuz those obviously aren't. Those are rollers. They must be the larger size rocker bolts.

Even if I wanted 92 heads (which I don't), no rebuilder uses them that I found. The only thing wrong with these heads is that they are stock.

What does the E in EV6 stand for?
