    That should work just fine. Good luck and I said earlier, build some oil pressure with the starter, plugs out, first.
  2. Mark Maras
    But first recheck the compression with the throttle wide open.

    The only thing I can add is I remove the plugs and turn the engine over until I see oil pressure, then test. When I didn't start with oil pressure #1 would read low the first time and higher on the second test. Good luck.

    To each his own, I guess. It reminds me of the Excalibur from the sixties.

    Gas pedal? The best one for heel and toeing.
  6. Mark Maras
    Do you know if he held the throttle wide open during the tests?
  7. Mark Maras
    @jalexquijano This info may add another piece to the puzzle.

    I'd like to see the results from another compression test. I'm beginning to think it may be a bad oil ring as suggested by Zed Head.

    Keep the stereo, get rid of the car.

    in the Portland area we have an ON Point Credit Union ad on tv that has a beautiful blue 280. It only shows the hood and windshield but it's unmistakable.

    Is the black crud on #4 dry or oily and does it smell like fuel when you remove it?

    @jalexquijano. I remember discussing changing the valve seals several times. Did they ever get replaced?
  13. Mark Maras
    Kinda reminds me of the E Type hearse in the movie Harold and Maude.
  14. Mark Maras
    But, as I recall, the compression was good on all cylinders. Correct me if I'm wrong @jalexquijano.

    I understand the logic in having the fan clutch heat actuated BUT I think it would have been an improvement to have the fan clutch only actuated when the vehicle slowed below 10 mph.. As Zed Head stated "The fan only matters at low (or no) vehicle speed.

    I actually had two old Chevys back in the day. A 39 long bed pick-up and a 49 deluxe coupe. As I recall the 49 had a push button starter and the 39 had a starter pedal that you stepped on to mimic a starter solenoid.

    Our daughter just got a new Nissan. She showed me all the bells and whistles it had which included "push button start". The look on her face, when I told her my 49 Chevy had push button start was priceless.

    As I understand it, 14.7:1 is the ideal ratio but everything I've seen and heard says a gas engine runs much stronger and COOLER with the mixture somewhere in the 12.5:1 to 13.2:1 area.

    This part of the mystery seems like a bad ignition switch.

    When you say larger oil pan, do you mean wider or deeper?

    When you install the new nozzles be sure the attachment points on the choke linkage (flat bar with bent ends) are exactly parallel with their mounting points. The linkage piece frequently needs a bit of a twist on one end or the other to re-align it. Misalignment will cause the nozzles to stay down in the choke position.

    That's the bottom of the fuel nozzle. Have you retrieved the brass nozzle that attaches to your broken piece? My first thought was Ztherapy (Salem, Or.) as a source for the nozzle.

    I'd pull the valve cover, cover as much of the surrounding area with some thing to catch the oil, (shop towels, bath towels, plastic sheeting, etc), start it, ensure the cam is getting oiled from one end to the other, shut it off and clean up the mess. That's how I discovered an early oil spray bar that was severely gummed up.
  24. Mark Maras
    You can find a tutorials on YouTube for specific projects like valve adjusting.

    I've used mineral spirits to soften the rubber and wintergreen oil to keep the rubber soft. However, I just googled "rubber softener" and found that many are using silicone spray. Soak the rubber piece in silicone spray (it contains a plasticizer), seal it in a baggy for 3 - 7 days and voila, refreshed rubber. It's worth a try.
