Engine paint

[Broncobill78]

Well, it's admittedly been more than a few years since I built one but the last time-round what I did was to buy a hi-temp primer from the PPG dealer (at something like $12 a can TEN years ago) and after deburring & cleaning the engine w/sufrace prep I used the primer & then followed it with the standard hi-temp Dark Ford Blue. It STILL peeled from the areas *right* around the exhaust ports within 3 or 4 days but the *rest* of the paint DID hold up. Take that for what it's worth.

I with most everyone else here. F**k Toyota. My buddy has one and the only thing it does it break down. It got to a point when he ditched the cheapass toyota axels and threw full size dana 44 from his blazers under there. He also junked that crap suspension and put in true four link. Sure toyota has sweet commercials, but their trucks are junk! They put so many sensors in it that if you have an engine problem you have to either replace all the sensors or buy the computer diagnosis tool for checker. The airbox sensor makes the yoda always run like sh*t and dont even get started on the rusty body. That truck is a 91 and has more rust than my 79 bronco. The paint is desent compared to the chevy primer in the 80's that completly sucked. So if you want a piece of junk, that may last forever if you baby the sh*t out of it buy a toyota, but if you want something forever that you can really have fun with, get a ford. Chevy is ok too, I guess.... Well better than dodge!

Dave, did you just do surface prep? Did you get the motor steamed? Thats the only way I would repaint the block. Thats just me being cheap I guess. LOL

Hard to say /emoticons/[email protected] 2x" width="20" height="20" /> The engines that I bothered to clean & paint were the ones that I had hot-tanked & shot-peened. It was only something like $30 to have the block & both heads hot-tanked. I was having the rods shot-peened for the actual *purpose* of having them shot-peened but the guy offered to do the block & heads for an extra $50 since they were there in the shop anyways and that was about even with the $65 that the sandblasting dude wanted to shoot them w/walnut shells. As I recall it was something like $250 to have the frame & sections of the body done w/straight sand. In the end I figured it just wasn't worth the extra $15 to drag everything over to the blaster's shop so I had the machine shop shoot them. To be honest, for the simple purpose of just painting them I really didn't see any difference after they came out of the hot-tank (well, yeah, the texture changed a bit not nothing dramatic). If I had it to do again today I probably wouldn't spend anything on them beyond the hot-tank. since then I've actually hot-tanked quite a few parts on my own using a simple Wal-Mart $65 Turket Fryer and some Tri-Sodium Phosphate. The Turkey kit has something like a 30gal pan and the burner to hook your propane tank up to. As long as you have a propane tank you have everything. Set the thing up, put about 3lbs of Tri-Sodium Phosphate in with about 20Gal of water then heat it up and soak the parts. The only rub is that since it's water based you have to either prime it right away (very easy since it comes out of the tank very hot and dries within 5 minutes or so) OR shoot it with something like WD40 to keep it from rusting. Either way, the hot TSP strips off everything and leave a clean, bare part. Just something to kick around. I have a few pages about it on my site. http://www.broncosaurus.net/sb10.html

Thats one the most awesome ideas I have heard in a long time. Using a turkey fryer to hot tank parts! Thats priceless! I might just might have to run to walmart and get one! LOL I was just curious how you do it, I have always gone to a machine shop too. However I have only done it a couple of times. Walnut shells in the sand blaster? I was watching engineering disasters a little while ago and they were talking about a helicopter motor that failed due to a piece of walnut shell getting stuck in the jets that spray oil into the motor. It clogged the motor and the piston got to hot and failed. It ended up killing a few people, so I guess not using walnut shells was a good idea. Just thought I would throw that little tid bit around.
