Evap Core Differences (AC in LS Swapped K10)

Views: 77 | Comments: 2

Hey Guys,

I've been reading posts on here for a long time for information on my 79 K10, and it has been the best resource I have found.

I am working on getting all the parts to put a Sanden 508 on the 5.3 that I swapped into my truck. The issue that I am currently facing is my evap core. All of the images that I have seen have two male fittings coming out of the evap core. My connection that goes from the evap core to the condenser is a female connection. I was using the diagrams on L-C Truck and images of similar setups to figure out what line attaches to the female side and I cannot find any other evap cores that have the same fitting on the bottom. All the evap cores I have seen have a male fitting on the bottom. Am I missing something here? I included an image to show the lower fitting.

Note: When I bought the truck, the AC lines and the compressor were already removed so I do not know if there was another component connecting to the female side to the condenser. From the images and diagrams I have seen, it does not appear that anything goes in between.

Any help would be awesome!

I have a 1987 2wd 1/2 ton with the pulse wiper system. switch on the column washer motor behind the tank. Problem is the wipers wont shut off. At times I can get them to stop by twisting the switch back and forth. My motor has 2 connectors, one for the motor and one for the park position. with the connector pulled out of the park position, I checked the contacts with an ohm meter and the contact is open. with the key on I have 12 volts on the white wire of the park connector and 12 volts on all three wires going to the motor. the wipers have the low, high and intermittent functions when selected on the switch
thank you for any assistance, btw I have read your wiper section and ended up confused

Uncontrolled tire bounce

Last year I had installed some cheesy KYB shocks on my K10.

On several occasions, driving over some decent bumps in the road at about 30-40 mph, one of my rear tires would being bouncing uncontrollably, shaking the entire truck violently.

Slowing down cured the symptom obviously.

It was almost like the shock froze and the tire went into wild vertical oscillations.

Suspecting shock failure I replaced them with Bilsteins, symptoms go away. (yay! I joined the club!)

Last week it happened again, so l turn to the brain trust for help.

Any ideas or similar experiences? TIA!

SBC random high RPM knock

September 14, 2024, 01:15:21 PM by Banjobend | Views: 136 | Comments: 5

Hey guys, I have a c20 with a 350 that is mostly stock. 4brl carb, performer intake, headers, and dual exhaust. Been tuning the trans today and I ran it faster than I probably should have. No tach so I'm not sure of the rpms. But a couple times before the 2-3 shift, I heard a couple loud knocks. Sounded like a rod. When it happened I noticed a puff of blue smoke out of the exhaust. No noise at idle or when I'm just cruising.

Wondering if I'm about to lose one out the side of the block?

Paint my new gas tank?

September 13, 2024, 09:57:34 PM by Dr_Snooz | Views: 156 | Comments: 4

There's a new gas tank waiting for me when I get home. When I remove the old tank from my Suburban, I'll take opportunity to clean up and paint the underside of the body, replace the old rubber hoses, and make sure everything is nice before I put it all back together.

One question, should I paint the new tank before installing it? If so, what should I use? Bear in mind, this is California, so rust isn't an issue. Also, certain specialized coatings, like Eastwood's Tank Tone paint, are not available here.

All input is appreciated.

Thank you!
