Hello guys, I'm Alexey.
I just replaced stock Camshaft to WOOD W6. And also changed: S&S Hydraulic Tappets 33-5352, S&S Quickee Adjustable Pushrod, S&S Breather Gear 33-4250, and inner bearings.
After work done, I stated engine. The engine started up better than before the replacement.
But I started to hear extraneous sounds near the camshaft. The sound is ringing (tic-tic-tic....). I record the video
When installed Quickee Adjustable Pushrod I turned it for 24 flat.
in hdforum I read info where need more turning for greater deepening of hydraulic lifters. I added 4 flat turn. Then test engine and hear sound the same
So, is the noise as expected?
I didn't measure with 0.108'' pin Pinion Gear and Cam Gear ( I have ordered this pins, they on the way) maybe Pinion Gear and Cam Gear not comparable
Video sounds can be very misleading but sounds like the rods are hitting the covers. Did you cut (shorten) the upper push rod tubes per S&S instructions?
Sometimes it takes a while to pump the lifters up.. take it for a 10-15 minute ride.. Also you can go as deep as 4 full turns and 2 flats on the s&s 32 tpi pushrods..

Yes, I cut off push rod tubes per S&S instructions
Today will check for witness marks on push rods
Also using stethoscope trying find exactly the place where the noise comes from
Yes, I cut off push rod tubes per S&S instructions

Ok. I've heard mis-matched cam and pinion gears. Too tight and they whine. Too loose and they clack like lifters bad. I've never heard one that bad and sure wouldn't rule that out.
If you haven't run it some more already and are unsure about the lifters being pumped up, remove the push rod covers and look for a pond of oil on top of each lifter. If still not satisfied, remove the spark plugs and push rods. Then turn it over with the starter for 15 seconds while holding a rag over the tappet guides. When full, they will shoot a stream out the center hole of the cup. Then you know they're pumped up!
If you have ordered pins and have a .0001, 2-3" mic, that would be my next suggestion. Or, you can simply change the gears and eliminate the guess work. If you don't know the procedure for that, get back to us before you remove the cam gear(s).
I have a lot of experience with many different Woods scams and the gears that come with their cams, well they're right on.. I don't think there's an issue there.. Woods cams have quick ramps and if you did not increase spring pressure then you're gonna have noise.. set them to 4.2 turns..
Check for witness marks on push rods. Might be hitting the tubes.
Do not see witness marks on push rods

Have remove the push rod covers and not found pond of oil on top of each lifter, then I remove push rods, and turn starter, after I see every lifters are streams out.
Checked by stethoscope where the noise comes from. Most of noise form red places, from blue significantly less
The noise I don't recognize is the "ringing" toward the end of both videos when the air cleaner is in view. My be a wild shot, but is there any chance you bent the timing cup or tightened it down with the tab not seated in the cam groove? If it's hitting the cam sensor, that would make a lot of noise.
The cam/lifter noise may be normal for a Woods cam, I have never used one. Any cam over stock will almost always seem noisy. And again, the audio from videos can be very deceiving concerning engine noises. They often amplify certain pitches and surpress others, making something sound 10x worse than in person.
