If it has never been removed it can be really difficult to get loose. Usually some heat and a tight-fitting square-drive removal tool are needed.

Hopefully the engine machinist removed the original plug to properly clean out that oil passage, then later on it was replaced by the engine builder with a new hex-drive plug during engine assembly.

Morning, fellas. Two questions for today:

1. Regarding the 3/8" fitting by the distributor for the oil pressure gauge, should I buy a 90° elbow to connect the nylon hose to so it's not coming straight up from the block so it's less likely to kink?

2. What did you guys think of my oil filter autopsy? Look ok?

I'd get rid of the Nylon tubing.
If you look at the link of the gage you bought it will show you the recommended copper tubing kit.
Not 100% sure, but I don't believe the plastic stuff is even allowed at the track

Been watching with interest since I had my own oil pressure adventure a few years ago.

I've learned to check oil pressure gauges against a known calibrated gauge using air pressure before installing them. I've found that nice electric gauges can still be off a good bit, but even the cheaper mechanicals tend to be pretty accurate. You should be able to trust your new gauge.

Driving at 3000 RPM fully warmed up at 205* and I'm at about 42-38 PSI.

This is still lower than I would like, but if you are at 205 deg during a sustained high RPM run then it would not surprise me. If you can get it cooling better so that it runs 180-190 then the pressures will probably be higher. Same for pressure at idle especially after a hard steady run.

But dropping pressure at high RPMs is not good. I've seen see that on some of my cars during sustained right hand turns- like dogging it around an interstate loop with a stick in 2nd gear, obviously caused by uncovering the pickup. I don't think that should happen in a straight line if you have enough oil in it though.

1. Yes, it will look cleaner too, do yourself a favor, paste, no Teflon tape!

2. All good...love the manly Platex gloves!
