I've been sick since last Saturday, as I mentioned elsewhere. Still sick, but getting a bit better, or at least symptoms are progressing. Today was 40F, so after going for coffee and banana bread, I decided to work on the truck. The steel bolts came right out of the aluminum intake with a pink 12 point Harbor Freight 10mm. It didn't look like GM used any sort of anti-seize or thread locker, which I thought a bit weird, but since they've functioned this long, I guess I can't say much.
I cleaned the surface off with a rag and brake cleaner. After some digging (always digging) I found my silicone dielectric grease, and I applied some to the o-ring. The toque spec is 12nm or 106in-lbs. I set my torque wrench and start turning.... and turning, and turning, then all of a sudden the socket skipped. Tried reversing it, and the socket skipped again. Grabbed a six point, and removed it. Even the 6-point was loose but the bolt looked fine. Then it occurred to me that maybe it wasn't 10mm, as it did look a bit small. Tried the 9mm... too small. It was 3/8ths! I just assumed metric since it goes into the intake and not the block or heads.
Back to the torque wrench... I started adjusting the wrench down, and getting it to break over on other bolts. Then re-set it, and torqued the Evap solenoid to 106in-lbs. Is it typical for torque wrenches to have issues in the cold (40F)? I'm pretty sure that even when I had the 10mm socket on, it wasn't breaking over when it should. I always store it adjusted all the way down. It's a 90's Craftsman, so while not a truck-tool, it's no HF special, either.
The original hose connected just fine, even though I did break a little chunk off the locking ring with my finger nail earlier. It's an o-ring seal. Started the truck up and let it run. No vacuum in the gas tank anymore!
Edit: A few comments about the pictures.
1: SMP USA made, thankfully
2: picture where some of you have the second solenoid, I just have a vent cap.
3: weird blue looking line in the port. I used a pick and it's not an o-ring. The o-ring stayed on the old solenoid.
4: finished
