Understanding Valve Springs – Part 2

In this episode of Steve Tech, Steve Morris picks up from the Part 1 video to explain what you need to know for proper valve spring set up and how to prevent spring surge.

Good job showing and explaining the process 👍

I've watched this video a couple times and it still look up SteveTech to be reassured I'm making the right decision buying expensive conical springs or at least Ti retainers

[bryanemerson]

This was exactly what I needed to hear. Thank you.

[grantk.]

Thank you for sharing your awesome knowledge!

[AndyB]

Ty for taking the time and explaining it, so it's understandable.

[john-martin]

Thank you, very well and clearly said.

welcome to the sme institute, great vids thanks

[davidsawyer]

Appreciate the info. Have a suggestion. If possible load videos in order in the playlist. In other words the playlist plays the latest video first instead of the first in a series. Thank you.

Comp Cams recommends their 948 springs for my .898 lift cam, which is set up for 332# @ 2.100” installed height. I have a feeling I will need to shim the spring closer to a 2.000” installed height to achieve the .050-.1” coil bind clearance, which will increase my seat pressure to 400+ on the seat and 1000+ open. Would this be too much pressure?

I like the single beehive except it lacks the redundancy of multiple springs. If the beehive breaks, there's maximum valve-piston damage. Good for machine shop business though.

So do you think a .660” set of dual springs and retainers is too large for a .560” cam shaft ? Turbo 4.8 ls set up

[Keyno]

Easier to understand, the spring begins to bounce at hi rpms when coil bind is more than 100/1000" 😅

[phillipfilides]

Can you use springs from a cast iron head on aluminum head

[ErnestoSantana-kqim]

Hello my friend, I would love to know if you can tell me what's the max lift these springs can handle, here are the springs specs: seat load 136 lbs @ 1.800'', open 412 lbs @ 1.170'', spring rate 438 lbs/in and coil bind 1.125'', thanks in advance

Why are OHC engines valve spring pressures so low compared to that of OHV engines? The OHC engines rev higher, yet their springs are smaller in diameter and the spring open and closed pressures are MUCH, MUCH lower than OHV engines. What is the physics behind this?

[russellhueners]

One engine builder on you tube had a .010 clearance on his head set up, came here to check, , yeh I was rite 050-.080

IF YOU ARE CLOSE TO BIND AT FLOAT IT WILL BAERLY BIMD IN DOING THIS ITV WILL RESET THE SURGE I SET BIND AT .050
