mcgovern61: I can again drop the head and see if the problem is apparent on the back side. However remember this is another head that was put in when the problem first developed. I do have another head that I just got back from the shop.

Joedrum: I already checked the headers and they were good

well this vid after I put everything back after removing the rockers on each side of the head and the noise still there although much less than before. https://youtu.be/6gt8HlCdPt4 Unless anyone disagrees I will have to pull the engine which was what I wanted to avoid if possible. I guess it...

slabghost: Remember problem was present before heads were taken of. New machined heads with new valves installed and head verified did the same thing. Different rockers same thing. No rockers on Piston #2 no noise. No rockers on piston #4 noise on piston #3 rockers.

To all: Please disregard post#60 I could not hear the noise because of the compression noise but the tapping was definatively there 83 Knocking with no rockers or spark plug on cyl#2. Noise not present was not correct noise was present

Here is the lastest vid This one with the plug in and as mentioned noise clearly on piston #2 https://youtu.be/vo7CghF1KpY

to all: Here is the latest vid. Here again I could not make out the tapping clearly because of the compression from piston 4. I placed a stethoscope and could hear tapping although greatly reduced. https://youtu.be/xPcUAcC2XWM

posted most recent 83 Knocking with no rockers or spark plug on cyl#2. Noise not present https://youtu.be/jna0ZwEJjak

Next I will switch rockers from piston #4 and see if the noise continues. I posted video of results of rockers removed from Piston #@ where I thought the noise was loudest https://youtu.be/v48mrkWw5YQ

Joedrum: I will remove rockers from pistin #2 where I beive the problem is as you suggest to see if it is the valves. Thanks

Dan: I also sent a video verifying the timing marks and settings. Before I pull the head off with another..... do you recommend I change the rockers from another head? Do you suggest I retard of forward on notch on the cam? If so which one and which way?

It did some damage but i am sure you will get it back in shape in no time Were you able to get some venison

welcome

great thanks

I suggest opening drain plugs on each float bowl to see if fuel is making it to each carb. Check the simple stuff first. Do you have fuel in the tank. Is the fuel petcock unobstucted. Is the fuel filter clean

Just posted anoth video which will again give you the noise and best describes the noise at varying RPMs https://youtu.be/wplv7tm_vQU

I swaped plug wires with anoth set I had a noise continues in the same area. It still sounds live a valve hitting. The sound goes away intermitently at very low RPMS and when I accelerate it going in line with a valve speed. I checked exhaust and all looked and sounded OK in the exhuast

they looked clean before I removed the heads. just put new ones because I wanted to start fresh

thanks esker: checked all coils and new spark plugs installed. spark on all 4 wires ok as I already checked.he sopark did jump to the head when the wire was closeer to it. But we wire conected spark is where it should be. Yes the noise will almost dissappear from time to time, when the idle...
