Looks like I'll have to replace the lifters in my motor. Is it required or recommended to change the Cam & rocker arms as well?

 

You need to inspect for wear, it may not be necessary. How badly worn are the lifters?

 

Agree ^^^ Keep everything in order from where it was originally positioned and check for wear. Parts without excessive wear may be re-used.

What is wrong with the lifters?

Good luck!!!

 

If your lifters are worn out or not pumping up properly, it is very likely that other componets will be worn out as well. Must inspect.

 

Whatever you do, use lots of lube.

 

The motor has zero miles on it. It was completely rebuilt back in 2013 but was put in storage for 4 years. It hadn't been started for 2 years and then I removed it from storage in 2018. Once I got it started back up, I started to hear the ticking. I removed the valve covers and checked the rocker arms and checked to make sure oil was pumping properly and all rocker arms were moving properly. Everything looked good. It never had the ticking noise before it went into storage. I was advised to also get a stethoscope to listen to see where it was coming from. Any guidance on how to properly use one?

 

Was the cam broken in properly? A collapsed lifter can pump back up (assuming hydraulic).

 

Yes, it was broken in properly. I would start it at least 1-2 times per week once it was put back together just to try and avoid any mishaps from it not running. Unfortunately when I put it in storage, I had moved to another state 7 hours away. I was hoping it would pump back up as well. I changed the oil, new oil cap to and the oil pressure seems to me good according to the gauge. I'm hoping I don't have to replace the cam

 

Perhaps you got some crud in the lifters. Adding a qt of Rislone engine treatment may flush the contaminant out.

 

Just a tick or a completely collapsed slap sound?
Are you 100% sure it's not an exhaust leak?

Just a tick... try running it up to op temp varying RPM from 1000-2000 to see if it pumps up.
Should pump up within 5-10 or so minutes.
I'll assume it's in the car and not on a stand. Take it for a short low-speed ride. Under load will be good for it.

If it's a slap like somethings broken then pull the cover and find which one it is. Remove the trunion and check it, the rocker, and the pushrod for parallel(roll it on a flat surface).

No need for a stethoscope. If it's an exhaust leak you can see and feel it.
A long metal rod or screwdriver held tight to your ear works just as well to hone in on the origin of the sound.

Change that coolant too.

 

I'll grab a bottle and try this before I begin to tear down the top of the motor.

 

I grabbed a bottle of Rislone. Still getting the same sound. Here is a video. What do you all hear?

 

Did the video attach?

 

No video. If its a faint tapping you need to drive it a bit and see if any crud will flush out.

 

Finally got around to pulling off the valve covers. At first glance, there were 6 pushrods smashed in. Pulled the intake and all lifters had been seized. I guess I should've expected this to happen since it sat in storage for 4 years and had only been started 3-4 times. I've got the new lifters soaking and will replace all pushrods. Cam still in good shape.
