225 stock except it has a super six intake and Stromberg ww3 carb uknown mileage
I went to take the car out this morning and it was idling rough, thought it might have just been not fully warmed up yet but thought I heard a noise while driving so I came back home and it almost sounds like an exhaust leak. I used a remeflex gasket and didn't notice any soot and couldn't find a leak. I thought well let me check the valve lash and when I started the engine with the valve cover off I heard this weird clanging/clinking sound near cylinder 1. I checked all the clearances and they were good. All the rockers were getting oil and all the pushrods had oil running down them. All pushrods appeared to be turning except for exhaust on cyl 1. I was able to spin the pushrod when the engine was off and that valve was closed. I loosened the adjuster and pulled out the pushrods, it was not bent and neither end looked marked up any more than suspected for regular wear. I put it back in and reset the lash and used a long screw driver as a stethoscope to try and find out where the sound was coming from and no luck. Checked the rocker shaft, side of the block, oil pan, fuel pump, oil pump, water pump alternator, each intake and exhaust runner and the timing cover. Couldn't detect the sound anywhere. It sounds loudest when I am over top of the valve train and sounds like it is down in the block. I pulled the dipstick to see if that was the culprit and no luck. You can't hear it at 750 rpms but you can hear it when I idle it down in the video at about 25 seconds. Any ideas what this could be???
Side question: I noticed all of the valve seals on my exhaust valves were at the top of the valve stems near the valve spring retainer and all of the intake valve seals were down on the head. Is this what happens when they go bad? Obviously they aren't doing there job but just weird they were all up.
A friend thinks it could be a loose pulley or gear so i'm going to pull the timing chain cover once the car cools down this evening. I did replace the timing chain and gears this March but have driven the car a ton since then with no issues. I have to pull the radiator in my roadster to be able to pull the crank pulley so that's why I have to wait.
Any help is greatly appreciated! I also posted this over on Slantsix.org too
