Would you believe sort of yes?Have you ever watched your wheel pass you, hit the tire wall, then launch into outer space? Because I have. Thankfully I had a friend willing to shag the thing a good 1/4 mile from said wall, which was another solid 1/8 mile from pit.
Good idea getting the motor ready to swap into the G body when the truck goes awayBrought the 99 to the shop for a pick up tube o-ring replacement. Took about 8 hours, and left me wishing all I needed in PA was a 2wd truck.

The factory o-ring was less circular and more tubular than it should’ve been.

Once it was out, it looked like half of it was in contact with the pump for quite a while, long enough to stain the o-ring with oil coloring.
Around the end of November, the oil pressure at cold idle dropped to low to mid 20s from a constant 40 and the engine started running for several seconds in colder weather with 0 oil pressure, and only reached 40 when warm.
8 hours, a bunch of cleaning, cursing, and the occasional drop of oil in the eye, it went together and I saw this on the dash less than 4 seconds after starting it:

50 psi. In an engine that *may* have 300k on it.
I’m overjoyed, too bad the rest of the truck is so bad, I’ll need to replace it this year.

Except the car was my 1985 Riviera T-Type with the hot air turbo mounted between the engine and firewall, it was going 80mph on I90 in New York just after the Albany off shoot, the tire in question was the front driver side that broke 3 of 5 wheel studs and bent the other 2 as the wheel then came off, it bounced in the air at eye level as we passed it (driving to a corporate meeting in NJ from MA) while I was in the far left lane and had to make my way to the RH shoulder, and, the new trainee in the passenger seat looked like he peed his pants.
Oddly enough, car and tire ended up within a hundred or so feet of eachother.
About 5 hours at a diesel mechanic station later as they had to machine out the axle for 5 new oversized studs based on what was available later we drive to NJ, and, a day later on the way home on the i87 Northway just north of the 287 interchange I heard a telltale ping and pulled into the rest area... down one lug nut again already. Had to park the car, hang out till 130am waiting for someone to come with a chase car to watch for me and warn if things got worse before a wheel came off and limped it home at 35mph.
I did the O-Ring in my 2001 Sierra 2500HD when I did the oil pan gasket a while back. 200k mile 6.0l that is almost 60psi cold and 50psi hot.Brought the 99 to the shop for a pick up tube o-ring replacement. Took about 8 hours, and left me wishing all I needed in PA was a 2wd truck.

At the time it started as disbelief, then became comical for a bit.... the waiting at the service station while they did what sounded like a medium term repair was weird, the place had the contracts to tow/impound all the DOT trucking violators so I heard a lot about a "boston Buffalo express" who apparently suck at logs and played fast and loose with rules....I'd say that's worse than it happening on a race track. I waited all of 2 minutes tops for a tow truck.
It’s a Fel-Pro replacement, just whatever the local O’Riley’s had.I did the O-Ring in my 2001 Sierra 2500HD when I did the oil pan gasket a while back. 200k mile 6.0l that is almost 60psi cold and 50psi hot.
The new GM replacement one is the Red one from what I've seen, where did you get the black one?
I’ll admit myself to an insane asylum before I stuff a LS in my current car.Good idea getting the motor ready to swap into the G body when the truck goes away
