Could low oil pressure cause a valve clack at all rpms but not set off an oil light? If so what range would the pressure have to be?

[badknuckles]

Yes I realize that healthy oil pressure is between 30 and 60

Sound like your timing may be a little high... Did you check the timing???

[badknuckles]

Timing high? How so?

[delawarebill]

what is the pressure while idle and running down the road (rpms)... if its very low all the time, like under 10# then u have another problem.. u didn't say what motor.. but chebby's will idle hot at about 15# and not tapping... maybe u need to readjust or u have a bad lifter????

It is a 318. Did not make any noise when I got it.put a new cam and lifters in and now the whole valve train clacks away. Everything looks good lifters etc, now I'm on to oil pressure. I did knock away some carbon while in there so maybe plugged screen. But I know the oil pressure gauge works and it is not lit.

Well.. When I post this.. You didn't have much Info on the motor..I said timing because when the timing is to high you will get some lifter noise.. Now if the lifter's isn't adjusted right that will also do it... Now.. as far as low oil pressure..You really never said you had low oil pressure..This is what you where asking..I was just pointing out a few things that could cause it..Good luck..

I will actually r check the timing,i was just unsure how that caused valve train noise....at this point asl tips are helpful. Thank you

Is the new cam ground on a reduce base circle? This would cause your pushrods to be too short.

Excessive timing could cause pinging/rattleing from detonation.

If the lifters are actually collapsing, it could be from the carbon you knocked into the oil pan. Lifters have some of the smallest clearences you'll find in a motor, doesnt take much grit to plug one up, or stick to the plunger.

i believe it is a reduce based circle but how can i be sure?

Call the manufacturer.

The shaft that goes from the cam to the oil pump my be stripped in side the

pump,by the cam is a gear drive to the pump that you meshed the teeth

together ,if this has happened the pump will still turn but not enough flow for

the motor.Mopar small blocks are known for this.Any questions dont hesitate.

Oh the shaft is a hexagon shape at the end that goes into the oil pump.

here something to look at

Would like to say, the cam manufacturer checked out the play and provided me a free set of pushrods 60 over. Yay once again to local businesses
