Distributor and timing
Kinda simple. Took my intake off to replace gaskets. Marked the distributor in relation to the intake so it'd go in like it came out. Which it did, does it still call for a timing light? Only ask cause it gets warm pretty quickly. Everything checks out with no codes present.

Just adjust it and see if you like the results. If you do, adjust it the same way some more. Keep doing that until you can't make it better any more. If not, put it back.
THE ENGINE doesn't need "a light" to know whether to run right. Neither should you.
Not rocket science.

That was all. No need to get all fancy here.

Re: Distributor and timing
if it needs to be hit with a timing light for proper timing
And your timing mark is ...... how far off ????
So what happened when you advanced it?
Sometimes DOING stuff is more effective than arguing on the Internet.

Re: Distributor and timing
I wouldn't bother with a timing light until AFTER the engine was running right.
Then I MIGHT, MAYBE, if I didn't trust my own ability to tell whether the engine was running right again later on, MAYBE, I'd look at it and see where it is so I could put it back. Although I think it's been prolly 30 or 35 years since I last did that, I suppose the urge could strike at any time.
All a "light" does, is blink. It doesn't tell you what "total" timing (what matters) THE ENGINE wants. It doesn't tell you how far the "low speed retard (aka "centrifugal advance") retards it at low speeds to avoid pinging and whatnot. It doesn't tell you haw far out of whack your timing mark is, which I'd almost BET MONEY, if I was the betting kind, that it's more than 5° off from reality. Even assuming your "mark" is right, and you set it to some random "factory spec", if YOUR ENGINE is the slightest bit diffferent from that one, or the fuel you run is the slightest bit different from what it was 15 or 20 or 25 years ago when that spec was written (YA THINK????), or your expectations are the slightest bit different from those of whoever wrote whatever "spec" you're reading, then setting it to some "spec" is doomed to failure.
Adjust it until THE ENGINE is happy, as measured by how YOU like it. You might have an entirely different set of criteria for "like" than me or someone else. "Like" might be defined by some combination of throttle response, power output, engine temp, fuel consumption, ease of starting, and who know what all else, that is NOT captured in some "spec".
Go out and DO SOMETHING to your car, and see if it makes it BETTER. Typing stuff on the Internet, calling me childish names, isn't going to make your car run any better.

Either way, I still think the WHOLE point is being missed here. Either I didn't explain it clearly enough or idk. I've put many many hours of work into this car and every so often I like to get on here and get help, suggestions. I don't have time to spend on here to make thousands of post. But I know what my issue is, thanks for all the input.
Re: Distributor and timing
dizzy was out...flash her up and put a light on it!!!
warming up quicker than normal.....are the new gaskets the right ones?
are all the water jacket holes popped out of new gaskets?
sounds stupid and i mean no insult but was the thermostat put in the right way up?
