Well ever since I installed the Cam on my truck, when I start speeding like around 60 or 65mph a ticking sound starts on the motor its weird cause it only does it at that speed and sometimes not all the times!!! What can it be is it the lifters or can it also be my oil pump, BTW I have a ported oil pump but at full throttle the gauge doesnt go all the way to 85 it only goes to like 65, isnt it suppose to go all the way to 85when its ported??? What can be causing the sound??????

 

my valvetrain is really noisy too. It just happens with allum heads and LT headers (I'm assuming youve got longtubes?)

 

Yea I Do

 

Did they go on recently?? Bty my stock op will show 80 psi @wot or atleast the gauge does

 

Not 2 long ago maybe like 5 months ago

 

If the noise just started to occur, I would go over the header bolts again..

 

How does that cause the noise

 

The agressive ramps of the bigger cam, and stiffer valve springs makes the lifters noiser.
