Found a k3500 ecdrw

All I know is the frame is right on the verge. If I don't descale and paint now or very soon it will end up like the burb, useless. I'm going to use chassis paint tommorow on the section under the fuel tank. The fuel tank was rotted as well. I went to descale and paint and the desdcaled punched a hole in the tank in a weak spot. I called GM for a new one..Holy shit!!!! I nearly fell over. 994$ for a new fuel tank. I really am beginning to think this is a govt conspiracy now the GM is owned by the Govt to discourage people from fixing old vehichles. A'hole AL Gore said he wanted every car older than 4 yrs or some crap like that off the road and I guess this is the way they plan on it. I I contemplated welding it but these things are thin and I would probably have to braze it and that requires alot of prep work to do safely. Entire tank needs to be steamed out and the rest of the tank didn't lok much better so I called LMC and they get 150$ for one and another 100$ to overnight it. I ordered it and went to Advance to get some stuff and the guy was like did you see if we can get it ? I was like "You guys can get fuel tanks ?" They will have it tommorow morning for 149$. God I love Advanced Auto. The guys here in Stafford are awesome. So I called LMC back and cancelled. I''m going to paint the chassis where the tank goes for now and reinstall and when I get some time real soon , I'm gonna pull the bed off and descale the rest of it and paint. The fittings for the sending unit are specialized and Parker could not match them with anything they had but he found some adaptors that Russell just came out with to go to JIC so he ordered me some. IN the interim I will chop the rubber lines and barb them in a way that I can easily change the fittings later, perhaps when I pull the bed off. Wil have pic tommorow. I will never buy a truck from the north east ever again. I'm so tired of workng on rusty crap. I burned up two needle scalers. I neded up buying a new compressor for the A/C cause the clutch is shot and a clutch was 150$, A BRAND NEW compressor was $183. No brainer there. I'll shelf the other compressor in case I need it down the road.
 
When you re-install that FSU smear a half a tube of grease all over the top of it and lines and fittings and stuff too! It wasn't easy getting a grip on my frame/chassis, but I did. A lot of rustoleum spray bombs. And as you said good washing after storms, and a very intimate spring cleaning with the hose at all sorts of angles under there...

Now when I'm under there I see a few rust spots where paint fell off, but I havn't spray bombed any yet this year. (Well I did my front plow mount and area before I drove to your house that day ! )
 
yeah I was going to paint it up good with antiseize. It had some kind of yellowish wax type grease on it that worked quite well. I don't know what it was.
 
I spray the underside of mine with waste diesel oil, the blackness of the oil makes it look nearly painted, so it looks a little better than just spraying it with automotive oil. The oil soaks in a bit and helps it last. I should have started doing it a lot sooner because the winter salt rotted out my bedrails and my big X crossmember. Took me a while to find something to spray the oil effectively, but what works is a cheap walmart campbell hausfield sandblaster. Just stick the hose in a gallon bottle of oil instead of into the grit.

Doesn't look as purty as chassis paint, but it's free, easy to redo every season and looks much better than dry rust. And I have to think it slows up the rusting process. When I swapped the new bed on I could have painted it (the chassis I mean, I undercoated the new bed), but I had a genius idea of mixing some black Zero-Rust (same as POR-15) into the oil. Sprayed it on, looked great if a little too glossy. Didn't last though, seemed to wash off. If I had the brains to keep after it and oil it more frequently I'm sure the truck would be in a lot better shape underneath. But I load it down with sand/salt mix and leave it, sometime it's in there for a couple weeks. I rinse it up underneath every chance I get, but the roads are salty all winter here. Just can't be helped.

Just something to consider:

Used engine oil has carcinogenic elements. Aerosolizing it makes it worse.

Again, just something to think about.....

Hmm, seems to be some evidence that used diesel oil isn't - http://toxsci.oxfordjournals.org/cgi/content/abstract/13/3/545

its better to leave the truck salty underneath until spring. after the layer of salt on the metal interacts with it, the salt loses it's corrosive abilities and almost acts like a barrier for the new layers of salt. If you wash it all the time, you are only exposing fresh corrosive salt to freshly cleaned metal.

i had wondered about that but never took the time to reaserch it, but it does make sence
 
My father-inlaw used to spray the underside of his cars and trucks with boiled linseed oil. It dries somewhat like paint. He sprayed every fall. Was very effective at holding the rust at bay. He used a undercoating spray gun to spray it.
 
I know the salt doesn't eat the metal until it warms up, so I don't rinse it when it's really cold. But I feel like I gotta get it off there when it's warm and the truck is turning white. I can lay awake at night and hear the salt eating the metal. Maybe your right, I'm just exposing fresh metal to the new salt. Can't win no matter what, this is New England. At least up not in NY anymore, they put salt down so thick you gotta plow it off! I've literally driven on salt so think you couldn't see the pavement.
I also don't park it in the heated garage, that just activates the salt to eat the metal.

hey, that's cool, I won't get cancer from my diesel oil. I'm sure I'll get it from somewhere else. When I was young I worked in a lube shop changing oil, performed an estimated 35,000 oil changes. Getting hot used oil on my hands all day every day. Hows that for carcinogen exposure? Might as well start smoking again!
When I blow it with air (is that aerosolizing?) I try to avoid breathing it. And my wife makes me do it outside.
 
Well I cranked out yesterday and today and she's back on the road. Very slighty shimmy still remains which is most likely from crappy Firestone junk tires. It is alot better though. Also the steering stabilzer was boogered in with the wrong size bolts(too small) and sloppin around. Went nuyts with the descaler(A must have in New england) and painted the frame where it was bad. Not gonna win any Picasso awards but it will stop the rust. Used POR15. Of course I got the stuff on my face right below my eye so using paint thinner right below my eye was fun. That's all sore now. Defintely gotta becareful with that crap cause it don't come off. I painted the tank with rustoleum primer and undercoated the piss out of it. Think the fittings pretty much speak for themselves but I have fittings on order that will allow the push lok to connect directly yo the fittings coming off the sending unit but for now I chopped the old lines and used them/ I purged the system and she fired right up. Thing stops 1000x better too. I think PO never bled the brakes when he hacked that rear Brake line in. I routed it nice and neat back the way it should go and bled the system. So far truck seems to be running sweet. when more time is availible I will take the bed off and finish cleaning and painting the frame. This truck will not see anymore salty roads. That is what I have the burb for. This truck will get parked at the end of camping season.

Wow! Kenny, that thing is looking great! I've just read through this entire saga! Quite entertaining!

Nice to actually connect a couple of names and faces as well! Thanks for the photos!

Yep, it does feel like a family around here. I think of it as home base for sure...

Good job. Truck is really starting to shape up! Glad that it didn't blow up on ya!

-Rob :)
 
Well The PO gave me a cap for it as well. I picked it up tonight. It needed a minor repair on the frame around the back window.

I love it when a Truck comes together...:D
I'm gonna hold off on a TM and a reflash until I see how it tows stock then do one thing at a time. The mistake I made with the Tahoe is I did everything at once and never really figured out why it overheated so much so the next mod I will do will probably be 4 inch ex and low rest muffler cat(empty) back.
