SRB1976, I think I know exactly where that parking lot is. It's a pretty place.
Busy day today! I finally got the heater core out after researching it last night. Turns out there were some nuts hidden under some tar paper... Took the whole shebang to the radiator shop. If you're in the Denver area and you need a radiator done or a
gas tank cleaned and lined Spike Radiator is the place. He's proper old school and has kept up with all the environmental certifications so he can still do his job. It's the only radiator shop I know of that still does gas tanks properly (he did my FJ40 tank a little over a year ago). I'm an air cooled guy mostly, and the few water cooled cars I've done didn't have any cooling system issues at all. This thing really did, and I didn't even know how bad it was... When I drained the coolant to change the hoses, I saw the inside of the rad was seriously gross. It looked like heavy mineral deposits from very very hard water. Turns out, if left for a long period of time, the coolant will react with the lead in the solder and leach stuff out. My rad was so bad, that the leaching had gone all the way through the solder joints pretty much everywhere resulting in white fuzzy joints and the deposits were all that was keeping the coolant in the radiator. Additionally, the deposits expand as the reaction continues, and it was pushing the tanks essentially off the rad... Seriously bad. Most rad shops will just bolt in a (crappy) aftermarket radiator that, in this case with the transmission and oil coolers, wouldn't be nearly as good and several times as expensive. A slightly more competent shop would call it a loss, and an old school shop with someone who didn't know what they were doing would have dipped it and then I would have had a sieve for a radiator. It's going to need a COMPLETE rebuild, but the end product will be the best thing out there. Essentially a brand new radiator. The heater core wasn't nearly as bad, and since he has a machinist on staff, he was able to take care of the sheared bolt in the crossover. I have no affiliation with the shop, I've just been a very happy customer and he performs services that pretty much don't exist these days.
Meanwhile, I got my dash back together. Time and desert heat weren't too kind to the plastic gauge panel thing (the part that holds the gauges, not the black thing). It's practically chalk at this point... I do have some really good ideas for the dash pad, and when I get to that phase I'll probably do a solid writeup. Photos have been lacking so far since I'm flying solo, getting too greasy to really be handling my phone, and I'm trying to get it at least to rolling project status asap. Speaking of photos though, here are some I took yesterday of some unknown circuit boards:
50 pts for whomever can tell me their function! They're on the same section of loom as the diagnostic port and have their own little boxes (I tried to photograph them in the context of their respective boxes) like the glow plug card.
Speaking of the glow plug card, I got one from (guy on the forum here that makes them) and pulled the old one out. The card holder is just dangling there by the pedals, but it has a tab on it that tells me it's supposed to mount somewhere. Where is that exactly?
My next door neighbor is a real life Leonard Hofstadter crossed with Howard Wolowitz AND recently Bernadette Rothstekowski (Big Bang Theory characters) who works in a university (CU-Boulder) physics lab with lasers and yeast (current experimental series) and makes all sorts of fun little devices to that end. He saw my glow plug card, pointed to one of the resistors and said in his German accent, "that little guy doesn't look too happy". He stared at the board (and compared it to the new board) while I was doing other stuff and was sitting there rattling off the functions based solely on seeing the circuit board... Pretty impressive by my standards. He was curious if there were any additional functions that would be nice to have. He has a mind to make one for fun and maybe sell a few. I'm still new to diesels, so all I could come up with was "overbuild the crap out of it so it never goes bad", maybe shielding might be something some people would like, and waterproofing. None of those are the sorts of functions he was talking about... Any thoughts?
