engine or timing ping/peck/knock... w/e u wanna call it -NEED HELP i have an engine ping/peck once my rpm's get about 2K and over. i can't exactly time my engine right now due to the fact that the balancer has slipped (i think) but i have moved the distributor in every position imaginable and the sounds doesn't go away. the timing itself is pretty close right now just judging it by ear. if you unplug the vacuum advance from the distributor, the sound doesnt come in untill about 3K instead of 2K. so, is this a 'timing' issue? vacuum issue? balancer issue? or what.....???:16suspect what is causing my engine to make this sound????
You are suffering from what appears to be preignition knock. Retard your timing by turning your distributor counter clockwise about 1/2" (as measured from the vacuum advance unit). Test drive it, if it still does it but a little later then turn it the same way the same amount. Basically what you are going to end up doing is turning the distributor counter clock-wise until the rpm rops to almost dying and then clockwise about 1/4". That should be close to right unless you have high compression pistons in it.
my pistons aren't real high compression, only 9:1. i've fooled around with the timing like you have suggested and im gonna try it again hopefully tomorrow. everytime i drive it, it seems to be the same as before i checked it. think i should drive it a short distance w/o the advance hooked up to see if it helps any? all i know is that it's gettin really annoying
Yep! if you have 9:1 compression switch to the higher octane gas. You may still have to retard the timing but you need a beter grade of fuel too.
i can't exactly time my engine right now due to the fact that the balancer has slipped (i think) but i have moved the distributor in every position imaginable and the sounds doesn't go away. the timing itself is pretty close right now just judging it by ear. I cann't see the balancer slipped since its bolted to the crank shaft. Sounds like the time chain slipped. Time to replace it.
personally, if you truly believe the balancer has slipped...heres what i'd do. remove the coil wire. remove the dist.cap mark the dist. with chalk, or something in the center of where the number 1 wire was. remove the number 1 plug.now, advance the engine until no. 1 is tdc.(top dead center,all the way up in the cylinder) if your balancer was spot on, you could static off it. see where the rotor in the dist. is in relation to that plug, (should be pointing off to the drivers door) but if you advance it( move the rotor against the spring) it will be center to where it fires.(the mark) thats static timing. should put you real close to where ya wanna be. see how it reacts to acceleration after that. put it on a higher idle(bout 1100) move the dist. counter till it almost falls on its face, then clockwise till it smooths out. move it back just a smidgeon , and i bet your dead on.
Here's a thought! If your balancer slipped, you need to replace it. It is dangerous to you and your engine. It could come apart without notice and at the worst time. Not to mention your engine would be in danger from being out of balance. Get this fixed asap, then worry about what you got going on ping wise. Either could seriously harm your engine, so beware.

You apparently have two or more problems. Until you fix the ability to base time the engine, your just guessing. Secondly, the timing advance in the distriburtor may be all wrong. Has a weight spring come off, has the vacuum advance been tested to be good, has a timing lite been used to see what the advance is doing, is the hose on the right port off the carb?. Until you get these all under control, you have no good hope of solving the problem.
