Engine runs fine but puffs smoke after sitting at a long light. Does not smoke during startup or normal driving. I lose a quart of oil between oil changes.

I did install valve seals which improved the issue. I am thinking my valve guides may be causing the problem.

I assume to correct I would need to pull the heads and have a valve job done.

I have very little budget. If I do a valve job, do I need to replace, springs, rocker arms, push rods, cam????

In addition, if that is not the problem, I will need to start digging into the bottom end. If so, I am looking at a complete slow rebuild of the motor.

Should I need to go that deep it may be more economical to let it smoke until I can come up with the funds for a crate motor.

Any guidance would be appreciated. Killing mosquitos after taking off from the light is a bit embarrassing.

Thanks,

Buck

Before you get into all of that, do compression and leak down tests for each cylinder. It will shed some light on your problem.

I think that's your answer.

If you start digging too far into an old motor you'll eventually just realize that a full rebuild is needed most of the time. Even if you identify the problem dead-bang , the solution is usually "yank it, machine it, rebuild it." And then you're right back where you started.

Thanks to all. You helped confirm reason.
