Based on what you've described, it sounds like you have a guide/seal problem. At idle, and after lifting pedal after accelerating you get vacuum sucking oil past the guide seal. That is because vacuum builds when the throttle plate in the carb is closed. When you step on it you are burning the oil by combustion so it looks like it is smoking less. Try the boot it, let off, boot it test I spoke of in previous thread. You likely will see a big cloud of smoke when you step on it the second time. Wait a couple of seconds after letting off before stepping on it the second time so the motor has time to suck more oil into the cylinders and I am guessing you will get the smoke cloud. Also when the car sits for a while after being shut off oil will run down the guide and make it smoke more when it is first started. (very common on 1979-1986 bowtie trucks) Sure sounds like valve guide/seal problem to me! Let us know what you find. |
