Post Adjusting Valves - Solid Lifters

OK Here's what I got:

Small Block Chevy
Comp Cam (Solid Lift) 294S
Roller Rockers 1.6 intakes / 1.5 Exhaust

Problem:

Noisy Valves (Clacking)

Here is the procedure I've been using:

INTAKE ADJUSTMENT: I Hand turn the engine in it's normal direction of rotation while watching the exhaust valve on that particular cylinder. When the exhaust valve begins to open, I stop and adjust that cylinder's intake valve.

EXHAUST ADJUSTMENT: I keep rotating the engine and when the intake is almost closed, I stop and adjust the exhaust valve on that particular cylinder.

I Called Comp Cams and they said that the clearances should be .020 and .022.

Any ideas what to do?

Solids are noisy! Are you adjusting with a little drag on the feeler gauge? you need the adjust with a lot of drag on the gauge or tight! with the rollers rockers and is this a hot or cold adjustment?

Are you using guide plates,screw in studs,hardened push rods?
This is the best way that I have used with out any problem .You want to adjust when the motor is hot. Starting on the odd bank 1,3,5,7, starting with the exhaust, turn it over until the #1 intake valve just starts to close back up from full open, then adjust #1 exhaust valve, then when #3 intake just starts to close adjust #1 intake, and run 5 & 7 that way, when you get to # 7 exhaust wait for #7 intake just starts to close then adjust #7 exhaust. Then do the other side the same way. I have a full roller cam & rockers. If this is done to the correct gap thats on your cam card your all set. My valve train is QUIET ,hope you are using a good lock type adjusting nut.Chrome valve covers let alot of noise thru, I like to use cast alumium covers and that stops 99.9% of the valve train noise and no clacking. Then if you hear a noisy lifter clacking you better check your gap again.Any problems please give me a email. Same way we do it on our A/Fuel dragster.

It was done Hot!

I would have to say there is a fair amount of drag on the gauge.

--"Are you using guide plates,screw in studs,hardened push rods?"--

Using all of the above.

They should be gaped when the valve is on its way back up into closing , because of overlap.
PLEASE check it that way to be sure.
Do you still have your cam card? I belive the gap should be .016 int. and .018 exh.
.020 & .022 sounds kinda big.

I tried it your way and the way Comp Cams told me both were noisy. After a day of driving it, it seemed to quiet down a bit. Either that or I'm just getting use to it. I double checked with Comp and they said .020/.022.

The cam card got lost.

Anyways it's all back together and putting out some sweet power. LOVE IT!

For years and years factory Duntov cams were set at 20 and 22. Made a wonderful noise. Still couldn't hear them at 70 over the wind noise in the 56 though.

Point is, we are all attuned to the quiet of hydraulics. Heck we're spoiled. The ergonomics of the least expensive car today far exceeds anything available just twenty years ago. Ten? The sounds you are listening to are normal. They are not going to go away unless you change back to a hydraulic cam/lifter system. The decision is yours.

Cool

1BAD80 got a question for ya. I just finished assembling the bottom end of my 377sbc, 400 crank in a 350. When I assemble the top end and install the solid cam rollers/lifters how do I get the correct pushrod height to order the push rods? I see a tol in Summit and was wondering if that was the correct way to get the push rod height/length? <img src="confused.gif" border="0">

What year are the heads? I ask this because I've seen cases where the pushrods rub against the inside edge of the pushrod hole in the head when using 1.6 rockers and won't allow for a good valve adjustment. I believe Manley sells a tool to correct this problem. Just a thought.

I agree with engineczar, what type of heads do you have stock or after market?
Yes,I used the tool from compcams and their site tell you how to use the tool, you MUST have the correct geometry and valve spring gap.
Some after market heads like dart have a taller deck height so a longer push rod is a must.
I also had a problem form the EARLY Dart Pro 1 heads.
On the Dart heads, They moved the location of the intake valve to help give more air flow and didn't give enough clearance to the pushrod. Thats what ruined the roller tip on my motor, and a clacking that took a little while to find. When I looked the flat was on the back side out of view. Thats why I rotate the tip now when I set the valve lash. If I gaped the motor cold it clacked a little more because of heat dissipation.
If you need any more information on sites please email me. I'm always glad to help a fellow gearhead out.
