new head gasket on drivers side now no oil pressure at idle..

[daedaestoy]

has anyone experienced this? i just replaced the head gasket and 3 bent valves on my drivers side head and now when it starts at idle it has no oil pressure and once you rev it above 1000 rpm it is completely normal.. what is going on? i have read it could be the ball bearing in the HPOP but what are the odds it just "FELL" out while i was working on the head? it was perfectly fine before this.. but right before i pulled it apart it was hard to start when cold.. but only did it 2 times before i pulled it apart.. truck is a late 04 f250 4x4 with only EGR delete and cat removed.. no tune or monitors....

You should pull the regulator on the front cover for the lpop, and inspect it. You may need to inspect the lpop too.

How do i find and or check those? is that where i pull the oil filter off and see if it fills quickly? and do you think me having he oil filter housing off while i did the head gasket could have anything to do with it?

Here is where the regulator assy is...
Pulling the oil filter and cranking over will give you somewhat of an indication of oil pump operation. Having the oil housing off has nothing to do with lpop failure, the oil pump is located behind the balancer. It's best if you hook a guage up to it to see how much lpo p pressure you have. How do you know your oil pressure is low? The sensor for the idiot guage only lets you know there is at least 7 psi.

Inspect for debris, some have found a broke/worn spring. I would stick a guage on it after you inspect the regulator, maybe before. That sensor could be bad. Make sure the connector on the top of the cover is seated well. The gears for the lpop cannot take much abuse, any pitting or scratching will affect the oil pressure. Btw, i've never had to mess with the lpop yet either.
