No way you want a 1/8" pipe plug hole wide open. That's a HUGE internal leak. If you want to lube that area drill a .020" hole in the plug.

So I go into Little Finsters Racing Team garage to start the drill into my oil pump to see my oil pressure dilemma when I got home from work today. Hooked back up my remote oil filter, took off valley tray center again and realized I need 3 pipe plug for the back of the block where the oil pressure lines go.
Start hunting and sure as hell, I'm out of pipe plugs. 1/8" NPT. It will have to wait. I wanted answers tonight so I could call up Trend tomorrow nd get my new pushrods or send mine back.

OK****UPDATE**** Found 3 pipe plugs and installed them and then started the drill in reverse and let it rip. Oil start dribbling out from the heads and down into the valley. Drill is screaming for about 2 minutes straight and the valley is not filling up like I thought it would with oil.
I did not turn the motor over this time, I wanted input from what you think?
Want to call TREND tomorrow and get the restricted pushrods.

Valley won't fill up. Heads may fill some. The problem is more volume is flowing through the push rods due to less restriction. This shows as lower pressure. Higher restriction = higher pressure. However low pressure really isn't the issue, it's the byproduct. The issue is lack of flow to the main/rod bearings. There is only so much flow volume. Extra flow volume to the wrong area robs volume of flow where it is needed. In my opinion you won't regret the smaller orifice push rods, it fixed mine.

I'm listening to you 110%. I just wanted to see for myself what was going on up in the valley. I was expecting a huge bathtub full of oil, which did not happen. Todd Marsh said I would see it in 40 seconds which is untrue.
Making the call to TREND tomorrow to see if they will fix my existing pushrods. I hope. Mike at TREND seems to be a straight up guy.
Thankyou Doug for all your helpful information.
Trend are great people. We are very fortunate to have Trend, Diamond, Pac. all local here in Detroit.
