Are solid lifters really that much noisier than hydraulic? I have just gone from a comp 270H to a comp magnum 282S. I used matching lifters and springs. The engine definately has a good tick to it now. I can hear the lifters clacking around. Is this normal when using solid lifters? My mechanic that installed the cam said that I will have to bring it back in a couple of days so that he can do a HOT valve adjustment. He set the valves when they were cold, But hasen't done them hot yet. Will this make a difference? Any help would be greatly appreciated. Thanks.

It will make a little difference, but you will still be able to hear them. That's one thing I like about solid cams, you can hear them. If it was a solid roller, you would be able to hear the lifters make ~whirring~ sound as the motor ran. OK, that sounded kinda dumb, but I didn't know how else to describe it.

Thanks kid vishus - I hope to hell that if the valves are adjusted HOT that it will quiet this motor down. Right now as it stands the noise is almost unbearable.What are the reasons why people adjust the valves hot? Is it because of the extra noise or is it for performance reasons? Any more reasons why this procedure needs to be done? Thanks once again.

My 427 (as is 99% of them)is a solid lifter engine.I do not find them to be noisy at all.I run an older 270S comp cam,used to be called a 270VDM.I set them at .018 cold.You will hear them,but they will all sound the same and it will be a sweet little tick,tick tick.....no clacking.. Many a V8 (Ford,Chevy & Studebaker) left the factory with solid lifters.... Cory ------------------

You must do the valve adjustment hot because the cam manufacturer has no idea what other components you run. I.E. aluminum heads, SS valves, aluminum roller rockers compared to another guy who has, Iron heads, steel valves, and steel rockers. With all of the different configurations the growth of the parts and therefore hot clearence (lash) at the rocker tips will be slightly different. In a factory application where all of the factors are known and can be tested they can give a cold lash setting and count on it being pretty accurate running temp. My 289 running an Isky solid is very quiet. I have Aluminum heads and aluminum rollers, not sure if that helps with noise or not. There is no question there is a solid cam in it when the hood is open but with the hood closed or in the car you cannot tell. On the other hand I had an MG that clicked and clacked to beat the band. Iron head and iron rockers. The big thing is that your clearences are correct and that the clearence doesn't open up a lot between adjustments. As long as that doesn't happen just consider it tghe motor singing to you. HTH,

He set my valves at.024 cold and the cam card called for .022 HOT. SO with my aluminum heads does that mean that my .024 cold setting is approx .030? So the correct way to do it would be to install the lash at approx 17 cold and when it's warmed up it will be approx .022 HOT? If indeed my valves are currently at .024 cold and .030 hot that might explain why the motor is so loud and sounds like it is going to blow up . Thanks once again.

Solid cam should not be noisy unless it's something wild. I had hydraulic (XE268) in my 351, was quite ticky ( found rail rockers were thrashing about and wore valves out) and I switched to a bigger solid cam with lash caps ground to be snug fit with rail rockers and it is virtually silent now. Clearance is .023" hot int & ex. My upcoming Cleveland will also have a solid cam now as will every engine I build for anyone. In my book anyone who is too lazy or stupid to adjust valves should not own one of these engines.

Is this ticking a lifter or rocker noise? A loose rocker can make some loud ticking noises. My engine still has the positive stop rockers (kind that you torque down and go) and one of them went loose and the ticking noise was heard inside the car. Solid lifters should have a soft tick but not be unbearable. Based on you losing oil pressure and ticking I'd be sending that engine back and tell them to redo it cause i suspect something is definitely wrong. ------------------

The only good way to do it that I know of is to get it to op temp, pull the covers and adjust them. Any cold setting will be just a guess. B

With that cam, it should be set to around 0.017" on the intake and 0.020" on the exhaust HOT.If you've got iron heads, the cold and hot lash will be about the same. With aluminum heads on an iron block, you'll need to set the last around 0.006" TIGHTER when cold to make the hot lash come out right. I used that exact same intake lobe with iron heads and set the last to a 'tight' 0.017" cold. I allowed for a little growth of a hotter exhaust valve, and set it to 0.020". Again, cold values with aluminum heads would be around 0.006" tighter. The engine didn't make much valve lash noise at all. Good Luck! ------------------

The key word here is HOT. Especially with Aluminum heads. We normally get an aluminum head motor a little too hot and then set the valves. Just be super careful, and wear gloves so you dont fry your hands!!!! We are used to it so it really doesnt bother us too much. After they are set, really you shouldnt have to worry about them for a while. Of course, we are wierd and set ours every 3-5 runs!!!
