I want to do a Amsoil bypass filter kit I have (BMK23) new in the box. I found out i needed a 1-16 thread adapter (BK300) to replace the PF66 filter. The only thing is the factory oil filter has no by pass so it must be in the filter block on the engine. Anyone know what PSI the bypass is set at? Seams the only filters I can get for the BMK23 are 3/4-16 and have a 11-17psi bypass. From what I'm seeing the LM2 runs 20-30psi normal. I dont want to be bypassing oil to soon.

well i haven't found a bypass pressure but i did find a oil filter that does not have a by pass. its the filter from the 08-22 6.7L Cummings. Amsoil EA080. its a 1qt filter. It also has a 1-16 thread with same size gasket as the PH66. So if it fits in the same location as the PH66 it should work with the 3.0L.  My Amsoil by pass kit calls for a 3/4-16 SBF filter but can only find the hard to get Jomar 9025 filter to fit that without a bypass. I did find a 3/4-16 to 1-16 adapter that i will use so the EA080 filter fits. 

The Amsoil EA080 cross references to a K&N HP-4003 you can find in the parts store.

I think the right move here is to just run the correct filter and roll with it.  Oil pump is variable displacement on this, and I don't think its worth risking a 5yr/100k mile warranty just to have some fancy oil filter contraption.

The BMK23 is not designed for this engine.   The only kit that would work is the BMK21 single remote kit.

i sent Amsoil a question about both kits. Im sure I will receive a we didn't test it so you cant use it. Just like they told me they dont have a adapter for the PH66. Yes they do have a adapter. The BK300.

I would imagine it would be fairly simple to go back to stock for anything warranty related. Just a little more involved than an oil change.

I'm curious to see how this goes. I've got less than 2 years left on my warranty, wish lists never end. Also as far as the PSI range goes. I've seen mine go as high as 60psi when pulling a trailer uphill or passing. Otherwise it's sits in that 20-30 range.

      You could try a used 1, they used that engine in the Astro vans, Plenty of them in the boneyard. Look for a wrecked or rotted 1 so the chance that it was scrapped for that reason and not a mechanical issue will be greater

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.
