The setting procedure explained in this video is for solid lifter camshafts only. Instead of lash, a hydraulic camshaft requires a lifter pre-load setting that can be anywhere from 1/2 to 3/4 turn past the zero lash setting.

Yes sir, you’ve got it! Where it gets tricky now is tightening the Poly without changing the lash setting. That simply comes with practice! Good luck! :)

Most camshaft manufacturers have their own specific recommendation for proper lashing of hydraulic lifters, we highly suggest following their recommendations for the proper procedure. Most times these directions can be found on their websites or in the box with the camshaft.

So what order do you do a entire motor in? Do you do all the intakes then the exhausts? or one cylinder at a time? Does cylinder order matter or do I just need to make sure I get them all? Sorry 1st time trying to do this

They do have this correct, although I use another method. There is, however, an error in the video where they talk about using lash as a tuning tool. Tighter lash effectively increases the duration/lift and does not increase bottom end torque, as the video suggests. Its the opposite.

Providing the poly locks are adjusted & tightened properly to begin with, there should be little reason to suspect they would need readjusted anytime soon especially with a stud girdle clamped down around them. Just to be safe though, check them after 250-300 miles!

Let me make sure i understand this. So basically to set lash you just make sure the valve of whatever rocker arm youre working on is completely closed (the lifter is resting on the base circle of the cam or 180degrees opposite the max lift point of the cam) then tighten the poly lock to the perscribed lash using a feeler guage to find the spacing?

I'm having a problem when I'm adjusting my valves. I will tighten the poly-lock to where I feel a drag on the feeler gauge, so I will then tighten the set screw. Same feeling on the feeler gauge. But then I move the feeler gauge and there is no more drag. What should I do to get a more consistent setting?

Greater valve lash allow more top end or horse power ? Why ? You allow valves floating ? As i know the more valve lash you have the less valve lift you have,so the less air come in the cylinder. I don't understand.

I've got those same rockers on the T-bird SC. Magnums I think. Found this video looking how to adjust them. I think I have a valve staying open too long. It has hydraulic lifters so it's easy to adjust them. You just get the push rod snug and then tighten it down a quarter of a turn more. I don't know it maybe the ignition but I think its a valve staying open. I can't hear anything with the stethoscope. Going to have to go in. Such a pain to get to them though.

At 1.08 the exhaust valve just begins to close, thus adjusting the intake. but the intake was allowed to almost fully close? When the voice said as soon as it begins to close. at 2.12 the exhaust should have been adjusted, look how far it moved in the gap to 2.13 and more at 2.14 the valve is almost closed! as we cannot see the lifter on the cam, which is the more accurate?

Hi i picked up a 302 small block ford and I noticed that the valve diameter for the intake and exhuast are slightly different, the exhaust is a bit smaller than the intake valves, but the exhaust valves have lash caps on them. two of them are missing, the engine hasnt ran like this or anything but is it normal that the exhuast and intake valve diameters are different ? and Do i need those lash caps? should they be on all of the valves, or just the exhuast ones to make up for the diameter difference from the intake valves. Thanks

I have a 350 with aftermarket heads with double valve springs and I just put a new hydraulic flat tappet cam in it and my valves will not stay adjusted. Some will be to tight and some will be loose. I also have poly locks and ARP screw-in studs. Could I have your input on what is going wrong?
@SummitRacing

+Austin Ledford, Multiple valve adjustments soon after the installation of a new hydraulic flat tappet camshaft can be a telltale sign of imminent cam failure. Depending on the size of your new cam, most times a hydraulic flat tappet cam does not require a double spring. This may well be the cause, as well as following the proper adjustment and break-in procedure!

Alexundre McConnaughy, Nothing different. After any cam upgrade you will need to go through this procedure. If it is a solid lifter cam, you will periodically need to readjust due to clearances opening up slightly over time and use.

It'd odd but it seams that all valve lash procedures are incorrect. Always adjust valves especially on a solid cam at TDC compression stroke . All engines have what you call valve overlap where both valves are open at TDC exhaust stroke. I've seen racers at the track adjusting #1 intake and exhaust then #6 exhaust at the same time. I had then go back and check #6 exhaust at TDC compression and it was way to loose. If in dought do a leakdown test at TDC exhaust stroke and both valves will show leakage.
