Valve Head Noise LOUD TAPPING

[batmmannn]

I have to do research just to keep up with your responses. If it is arcing I should be able to see it in the dark correct? I agree I don't think it would idle so well if it jumped time, It will take me some time to figure out the other parts you spoke of. You think that sound is an arc? Wow what a concept! I saw a post about lining up the cam gear. Now if I can figure out where that is on the engine. If I have let this car sit so long because of a bad plug wire I am going to cry.... Thanks so much!

to see the timing marks on the cam gears you take the panel off of the front of the engine that says 7m-ge. I actually just recently put a new engine in my jeep and it has coil on plug and its a little tricky to get on. So i put it on and thought it was on all 6 plugs so i started it up and it was idling shitty and had a miss and was making a loud arcing sound so i looked a little closer and realized the boot wasn't on the sixth sparkplug stuck it on and it ran perfect. As for seeing it in the dark I don't know if you would see it or not its worth a try.

Oh Ok yeah I know the cam gears now I was thinking of something else. Yeah, I did the timing belt on this car I can't remember how long before the problem started thats why I thought maybe it had jumped. It was running real rough, I think the plug wires I just found I bought back then but when I went to do the job I was discouraged because of the intake and how you have to remove it to get the plug wires run correctly. No way to feed those through I saw with the upper plenum on. That thing must be cake to take off though. I was thinking of a thread about the fuel cam sensor. Where is that on the car? ....? Thanks so much for your help! Hey wait a minute all you have to do is slip the rubber head off the distributer side of the plug wire and feed them through. I am a dumb ass.... like Popeye would say ...."Garshked!" lol

its not just valve tap or lifters and your timing won't cause a noise just a rough idle or sluggish condition it really sounds like you broke a valve spring but only one since it is a very slow tick sound were you revving it when this noise first developed and does it become less apparent or more when you rev? also i dont think your ignition timing would cause this without ALOT of other signals (hard slow start, overheating, cracking pistons, and alot faster noise) but imho it is a broken valve spring you should pull the valve covers and check them its not that hard of a job just remove intake where it splits and take off the valve covers the wires can stay in and everything

basic rule is a noise at half engine speed is valve noise or cam noise
full engine speed is ignition sound "arcing" or rod/main detonation etc.

I will have to see if it gets less with high revs. Would this damage the cam all this slapping? Can the spring be replaced with the heads on? Thanks, Scott

that's making quite the ruckus. lol =D anyways somthing is definitly wront in the valve train and also definitly not a rod knock.

I am trying to get the valve covers off. I am trying to remove the upper plenum, I think it is called. How do you get to those lower bolts that go into the manifold? There are some electrical structures there and in the center that I am not sure how best to remopve will post pics later tonight. Thanks

I uploaded a video with questions. Thanks,

Its a rod. Mine sounded the same way but only right after it fired up it made the noise (just like yours) for maybe 1 second. On the break down of the engine it was all chewed up and had 2 bent valves

Yeah, definitely sounds like a stuck or broken spring, although.. I have heard a spark arc that sounded like that (in the video). Its almost a metalic sound when it is wiring arcing, but an arc strong enough to make that noise would affect the engine (doubt that piston would fire).

I vote pull the valve covers.
