  1. Steam Comes Out of Overflow Hose

    70-83 Tech Discussion Forum
    Much appreciated, Dave M. That should handle the whole coolant issue and rehab the system. Thanks, TC
  2. Steam Comes Out of Overflow Hose

    70-83 Tech Discussion Forum
    Hi there. Just got a 260Z 'project". After a drive the radiator boils, or at least there's lots of steam vapor coming from radiator overflow hose. It has a pressure-release lever type cap. When I refill, it usually needs less than a gallon of liquid. Wondering if there are certain things to...
  3. Simplest way to take off the door??

    70-83 Tech Discussion Forum
    Yessir, chaseincats, I think I'm going to first try a follow-up lithium grease bomb, full coverage, no mercy,since it had "partially" worked so well. And mjmogab, the dremel is tempting too, if we have to go that step. Maybe it could either remove some burrs, smooth out a trouble area or just...
  4. Simplest way to take off the door??

    70-83 Tech Discussion Forum
    Well I had already tried the lithium grease and it cured it for a few closures and now the gunshot's back. But thanks, chaseincats, it's still the best fix result, and I thought it had permanently worked. But yes, that roller is the culprit, I can see it bind or snap, because there must be a...
  5. Simplest way to take off the door??

    70-83 Tech Discussion Forum
    It's the spring-loaded driver's side hinge I'm after. The one that sounds like a gunshot when I close the door. Whether I rebuild or switch it out, at this point I think it's gotta come out. I've tried lubing and spraying and greasing but I know something's worn. Probably the roller wheel...
  6. Correct carpet kit fastening?

    70-83 Tech Discussion Forum
    I'm wondering how the carpet fasteners on the seat rail are supposed to be used, whether for the underneath section or through the top front section overlay. Alas, I learned too late not to discard old carpet till the new one is all in. For that matter, I forgot if the carpet is supposed to go...
  7. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    Let me tell ya that acetone works crazy good. The icing on the cake. Now my little wounds from bumping while scraping, contorting, chiseling can start to heal while I'm finishing up the clean-off, prior to coating the floors. Thanks
  8. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    I'm mostly there, at least for the floor. I'm just trying to remove left over bumps of insulation residue. Will your insulation go all the way up the sides to the door sill like the carpet does? And is there any harm in covering the seat rail crossmembers on the floor with the insulation?
  9. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    Much appreciated. Say, were your floors completely sanded to bare metal before painting, no traces of oxidation? Or is it ok to have some discoloration/surface oxidation even after some sanding? Won't the rusty metal primer handle a bit of light rusty residue? I'm not able to completely...
  10. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    Your trans tunnel will be cool and quiet. I'm assuming we cover every part of floor with the new insulation, even the raised parts where the seat bolt holes are. .I know there are numerous choices, I think I'm going with Rattletrap. And what are you painting the floor panels with? POR 15?
  11. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    So the dual method is best. I'll try the dry ice then I'll follow up with chiseler and wheels. You're right, I guess the only way to be sure and complete is to get it all off. Besides, I'm thinking the new insulation I put in will be lighter and quieter anyway. Thanks to all for the...
  12. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    I have to wonder if it's necessary to go "all the way" with the removal of the tar insulation, at least for driver's side. It looks to be a true no-rust floor. The part near driver's heel that I scraped away took all my strength and a half hour alone. I would do the dry ice method, or even...

    Let the mini jackhammer rip. Thanks for the suggestion.
  14. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    Man that's excellent. So it's worth taking off all the factory stuff to see what's underneath. Kind of like catching a bad tooth in time to do a filling, instead of waiting too long and having to yank it and put in an implant.
  15. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    Good to know this, thanks. Can I just ask: 1) What's your preferred method of sanding for the floors, hand? Dremel? Drill with wheel? And 2) The Thermo-Cool has its own adhesive I think, but will you also use adhesive under the padding and then under carpet? Spray adhesive? Anyway, much...
  16. Is this floor a case for POR-15 or........?

    70-83 Tech Discussion Forum
    I've done a little test sanding and it reveals good metal, in most cases the original factory off white. It looks horrendous, but it's just rusty "dust" mostly at this point. Can I sand and use some rust converter or POR 15, which I've heard about? Also visible is some kind of semi metallic...
  17. 280Z Exhaust Fumes Culprit?

    70-83 Tech Discussion Forum
    REPORT: Well, the aftermarket hatch seal is all glued in, and though it took a few days of re-checking and re-gluing sections, it's done! The weatherstrip adhesive can be unforgiving and difficult, and some sections required re-doing. In hindsight I should have cleaned the rubber maybe with...
  18. 280Z Exhaust Fumes Culprit?

    70-83 Tech Discussion Forum
    The gluing has begun. Man that weatherstrip adhesive is some finicky brew. Lessons learned: for me it's at least a 3 or 4 day operation to do it right. This is because I must let it fully dry after bonding each section, preferably overnight, because it takes a long time to really set. Making...

    70-83 Tech Discussion Forum
    I should have specified hatch instead of door, but man that's good to know about your Kia seal recommendation for laying down better in the doors. This is because it's a much bigger pain to keep slamming a door shut, as opposed to the hatch which I'd probably open less than once every couple...
  20. Such a thing as minor rust repair scrape off?

    70-83 Tech Discussion Forum
    Tried searching, but most of the rust repair was cutting, welding, holes, matching metal pieces etc. I have the classic rear corners on the deck under hatch that each have about a silver dollar sized bubbling area. I have felt the metal directly underside, and it doesn't appear to have gone...
