lifter noise

[HitIt]

Is that the oil you broke your engine in with? It probably has nothing to do with your problem, but you definintely want to do an oil change after the first 30-40 minutes of run time.

well while oil was nice and thick this morn it never made a noise quiet as a mouse, yes i bought that oil thru hughes along with a 100% bypass filter they told me to run an hour then change filter and add another quart of that oil

Sounds about right ^^

Well if you do have a weak lifter, the thicker viscosity oil might be staying in longer and letting it stay pumped up.

Forgot to mention for the first 1.5 hours my fresh 440 had a lifter tapping noise from what seemed like multiple lifters. It went away and hasn't returned, hopefully yours will do the same. I do run 10/40 in it.

If the heads were milled flat it would cause the rocker preload to increase not decrease since the lifter to rocker distance is actually shortened up.

My bet is a bad lifter or one that hasn't pumped up properly. I'd go one by one as described above and see if any pushrods are loose. If you find one, pump it manually with the pushrod or long screwdriver while pouring oil on it. Start it up, if the noise goes away and then comes back you have a failed lifter. If the noise goes away it probably just had an initial problem. My motor did that too.

Here is a sequence to make the check of each pushrod go faster:

Position Intake Exhaust
TDC #1 firing set #2 #8
Rotate 90 degree set #1 #4
Rotate 90 degree more, set #8 #3
Rotate 90 degree more, set #4 #6
Rotate 90 degree more, set #3 #5
Rotate 90 degree more, set #6 #7
Rotate 90 degree more, set #5 #2
Rotate 90 degree more, set #7 #1

Yes, all I'm saying is he needs to check it to verify where the plunger is then go from there. The factory manual has the procedure but it need to be done with a dry lifter. My solution is to run adjustables!

im gonna change oil and filter and go to a heavier weight oil and see what happens first. maybe it just not been run enough only have about 45 min total of run time
