just finished a re-build and ran it for the first time. the valve train is extremely noisy any ideas?

comp cams retro hydraulic roller lifters, proper length comp cams push rods, hardened guide plates and harland sharp 1.5 roller rockers.


thx

take the valve covers off and look for clearance issures with the stud and boss.

also look at the hole the pushrod goes through

all while turning the motor over by hand

 

push rods rub against guide plates I was told this is normal?

 

sometimes you have to make the hole bigger in the head where the pushrod comes through.

nothing to do with the guide plates

what size cam and what heads are you usin

 

plenty of clearance with rods and heads
push rods do rub on guide plates
cam is comp cams 276
compression 10.5:1

 

check your retainer to valve guide clearance
