Does this sound normal for Cobra 1.7's?
I know roller rockers are a little noisy,but when I first crank it up,it sounds like a damn 7.3 Powerstroke. After a couple of minutes,they quiet down. I did'nt need to shim them,in fact, I'm thinking my pushrods might be a bit on the short side. I hit 22 ft lbs of torque after 1/4 turn of pre-load. Watch the clip,and tell me if these sound normal....

how would your pushrods be short? Did you not use stock length puchrods?

If they quieten down after running for a bit, then there is a oiling issue somewhere or your lifters are weak

I was thinking that as well. I know a couple of them had to pump up when I built the engine,and primed it before they got the pr's tight.

Were they new lifters?
