Default One noisy lifter on startup and sometimes restart........

Hi All:

Have any of you guys experienced 1 noisy lifter on startup?

I have about 1000 miles on a fresh build. If it matters, the cam is a mild Lunati and the lifters were supplied in their kit. The engine is basically a stock Pontiac 400 in my '78 TA.

Sometimes in the morning when I first start it up - one lifter ticks for some time - sometimes it's 10 seconds - yesterday it was for about the first 2 minutes of driving the car.

This also happens sometimes when I run errands and leave the car sitting in the parking lot for 10 or 15 minutes. On restart I sometimes get a tick for 3-5 seconds.

I'm running Shell Rotella T4 15W-40 and I get 20 lbs. of oil pressure per 1000 RPM when the engine is warm until I hit the pump relief at about 58 lbs.

On cold start oil pressure is an immediate 50 lbs.

The ticking always goes away - but it's a bit annoying. Is this just "the way it is"?

Thanks,
Chris
