    Need help Identifying Vacuum lines

    Unrelated - Either I need more coffee or I just don't know how to use the search function properly.... Does anyone have a link to a thread about the 7.4l injectors? I swear I bookmarked it in the past but I can't find it. I'm getting slight missfires at idle and consuming a bit of coolant...

    Need help Identifying Vacuum lines

    Awesome, thank you both. I've patched it with some vacuum line I had on hand, I was just looking to replace it if possible. Didn't think about replacing the fitting with hose too, good idea.

    Need help Identifying Vacuum lines

    Hello all, I need help sourcing these two lines and a boot. They are super brittle and both broke during removal. Part numbers would be extremely helpful. '97 K2500 Suburban 7.4L I need this line and the fitting on the left. Thank you,

    Prep for towing?

    Thank you all for the input. This may be a moot point...it's up to insurance at this point if it's a total loss or repairable. My F250 was found this last weekend and I picked it up from the scene (they were pulled over for no plates) Interior is gutted, paint is scratched, drugs were found as...

    What's your mpg...

    My 97 K2500 'Burban gets 12.3mpg avg last I checked. I usually just fill up at Flyers. She's not picky. Mixed driving. 454 + 4l80e on 33's.

    Prep for towing?

    Nice! Luckily I still have my hitch as I store it with my trailer. E2 fastway 10k hitch. I've been happy with it in high winds on the coast. This year California made it illegal to have any tune. You will fail smog immediately. My Volant while not Carb legal has woken the truck up a lot more...

    Prep for towing?

    Oh, I was wrong about gas. 4.29 a gallon while diesel is currently 4.49. Gotta love california.

    Prep for towing?

    My f250 was a 6.0 powerstroke. I got around 10 mpg towing. (A new turbo arrived literally hours after finding out it was stolen, that should have got me back to 13mpg) Gas is cheaper than diesel here and I expect/hope for similar economy. 3/4 and 1 ton trucks are not on lots out here. They're...

    Prep for towing?

    I'll be putting aside what insurance pays out for a new diesel, but with the chip shortage and COVID right now a new truck may not be obtainable for a couple of years. I try to use my trailer every month, sometimes more often. With my old truck I wasn't worried about doing longer trips...

    Prep for towing?

    It has the tow package - Would that have been included? I've been avoiding fixing this truck up... lol Edit: It has a transmission cooler mounted in front of the radiator already.

    Prep for towing?

    Hello , I have a '97 K2500 suburban (7.4l) that I need to get ready to tow my 25ft travel trailer. Trailer is probably under 7k fully loaded. I need to weigh it though. My tow rig was stolen (06 f250 diesel) and it's not going to bring in enough for a new truck... so I'll use what I got...

    7.4L CMP Retard -16

    There is a slight amount of coolant leaking out the lower / back side and valve covers need resealed... I'd rather do it all once lol.

    7.4L CMP Retard -16

    Thanks. My google-fu brought me to same injector from 5-0 mentioned in this thread. I do hope that's not the issue because I'm not getting that far in without redoing the intake gaskets... and while those injectors are cheap compared to my 6.0 diesel (not chevy, sorry it was cheap :P ) they...

    Ah, very nice. I'm in California and with the new smog regulations a tune will automatically fail me now, so I would be limited on the replacements I could do.

    7.4L CMP Retard -16

    They are very likely originals. The truck has sat for at least a month or so. I put some 'Injector Cleaner' in the tank before I drove off this morning. I will need to check the paperwork, the truck has been in my wife's family all it's life and it always went to the same shop so I've got...

    7.4L CMP Retard -16

    Got the distributor adjusted. now I'm getting random misfires at idle and running rough. clears up above 1k rpm. Ideas? Edit: I drove the truck ~40 miles to work. Runs and drives great. I idled a bit once I got to work and it seemed to have smoothed out a bit but definitely still a bit rough...

    It was user error. I was aligning rotor to the outside plug connection instead of the contact on the inside of the cap. She's back up and running! Thank you everyone. Cam retard is 2 degrees off and with the summit distributor hold down there is no room for adjustment. I need to enlarge the hole...

    Finally screwed with distributor again. Lined up tdc (used a screwdriver in #1 and verified it was being pushed out) dropped it in, rotor pointing dead on #1 fully engaged, won't start. Sounds like it wants to fire and I don't hear any backfire but there's some white/grey smoke out the exhaust...

    7.4L CMP Retard -16

    finally got around to it, timing was off though and it would start but not stay running... waiting for cooler temp to give it another go. It's too damn hot in the ca valley. My old distributor was destroyed. There is hardly a 'tooth' left. It's 3/4 worn through on each one. Holy cow. Hope the...

    If all goes well I should get around to pulling the distributor tonight. It's been 100+ and the truck is across the street with no shade. Will update.

    I forgot to mention I moved the truck across the street yesterday to wash some cars in my driveway (I have too many) and now it won't start. Click. Click. Click. F**k Looks like im doing my troubleshooting on the other side of the street. At least I have no neighbors directly in front of me.

    What is the best way to test for slack if you don't mind my asking? Not something I've really had to do before. Some instructions state to remove distributor cap, find TDC then turn the motor backwards until the rotor starts to move. Does this motor have accurate enough markings on the (I...

    7.4L CMP Retard -16

    I purchased a summit distributor... If I'm going to pull the old one I might as well replace it since I'm sure it's stock. Apparently some aftermarket distributors are not CARB legal. Stupid California. Don't think anyone will notice a distributor though...
