  1. Good idea - just swapped the plugs, I'll let you know the findings next time I take it out
  2. Interesting situation going on here today. I drove the car for the first time in about a month and a half and noticed some oil droplets on the subframe below cylinder 1 (closest to radiator). I looked up and saw a slight oil trail seeping out of the spark plug hole. I pulled the plug just now and the threads are pretty soaked with oil and confirmed there is a slight amount of oil in the cylinder using a borescope camera. The car runs great without any blue smoke - is my spark plug not in tight enough or does the plug need a new crush washer? If I take a brush and clean off the threads will it make a better seal? I know these engines are old and without being rebuilt will of course leak a bit but coming out of the spark plug hole is something excessive I feel. EDIT: the valve cover gasket is about a year old and not leaking - just checked.
  3. so Aisin would be the way to go and shouldn't rust?
  4. Looking at getting a new water pump but I've heard getting one with a cast aluminum impeller is the way to go as it does not erode in the coolant. I checked rock auto but none of them specify which material the impeller is made of. Any recommendations on a pump?
  5. Sounds good - I'll grab them from rock then. Are they tough to replace?
  6. Looking to replace the struts on my '78 and am a bit confused on what I'm finding. Some packs have 4 shocks (https://www.ebay.com/itm/353183501677?epid=1529958043&hash=item523b608d6d:g:LlcAAOSwv8ZfR-a3) and some have 2 struts and 2 shocks (https://www.ebay.com/itm/232991315727?epid=1540516460&hash=item363f5d570f:g:4lwAAOSwaPpb3Qib). Any idea which pack I need, how much of a pain it is to change these, and thoughts on the KYB ones?
  7. Just for clarity on the battery wires, the wire connected to the positive post on the battery would terminate at the starter motor.
  8. My theory is the fusible links blew as a result of the charge thrown through the harness from the coil when it exploded. Feasible?
  9. why is there no afm to tb hose...
  10. Yea - my alternator was overcharging the battery causing all sorts of weird electrical gremlins to pop up. After changing it out for a “new” (remanufactured ZX unit which is what was already in there), it was good.
  11. Is the TVS another name for the TPS? Also, regarding the "sticking afm" would it be the resistance wiper that would be sticking or the air door inside the afm?
  12. That's what we're trying to figure out. It happens every few weeks and is fixed by kicking the pedal a few times.
  13. "Lean boot" is a term coined by @Captain Obvious earlier in this thread to describe the car inexplicably running lean at startup.
  14. I thought the ecu (fuel injection brain if you dont want to call it that) was a bunch of microswitches on the s30s, no? @madkawThat's an interesting idea with the afm sticking. I don't want to switch the car to megasquirt because it runs fantastically 95% of the time especially after this tuning thread.
  15. Update again: I started the car today and got "lean boot" so I shut it off and restarted to another lean boot - I restarted it a good 4-5 times with no change so I took it out on the road anyway. It seems the only way to get the car back into regular mode is to leave it in a low gear and floor it/drop the pedal in quick succession - after that I didn't have a problem the rest of the day. My next guess is one of the microswitches in the ecu is getting tired. I'll try to give the computer a smack the next time it happens and will see if that does anything. Also for what its worth, I've noticed this never happens after the car has been sitting for days, it's only after its been parked and restarted after a few hours.
  16. In order to get to that, I'd need to remove the fender, correct?
  17. In the interest of guarding against potential rust, does anybody know the locations of the drains? If these are clogged, water backs up and rusts the metal out. For example, there are 3 drain holes on the bottom of both doors and one for the antenna Anybody know any others?
  18. I noticed today that after taping up that burned wiring sleeve that the car starts up WAY faster. I don't think I'm nuts, it's pretty noticeable.
  19. Update: Had lean boot happen today and noticed it while driving. I ended up kicking the pedal (flooring and dropping it) 4 or 5 times in quick succession and that seemed to fix it. So my guess is a periodically lazy TPS?
  20. I just went to test it and got 740 ohms. The FSM says it's bad if it is "far less than, or more than, 720 ohm" so I guess that at least on paper isn't it.
  21. Update: For a while (I don't remember how long) you could smell hot electricals on the drivers side of the engine bay when the car was running but without visible smoke or poor engine performance I ignored it (I know that was dumb). I noticed after the issue we've been talking about and taping up that burned pickup coil harness cover, that smell is now gone. Could a pickup coil wire build up resistance somehow and is there a way to check it? The car runs fantastically so I didn't think that could have been the case until I noticed the smell was gone last night for the first time in forever.
  22. open the foot vents and if you have the drivers window open, open the passenger's too
  23. Get your cabin fan going - that will equalize the pressure and push the fumes out.
