Not doing well

[icanfixall]

Some of you know my oil pressure concerns of the past. What I found while running a mechanical Isspro gage was the 1/8 copper tubing at the cut ends was so small that the oil pressure would come up and worst off all when I stopped the motor would stay up for about 1 minute!!! I used a small tubing cutter and thought I had cleaned up the ends well enough. Nope. I changed oil ports several times and finally looked at a new 1/8 inch fitting I had installed. It reall needed opening up. I even ran the motor with the line open and the oil didn't squirt out. It just dripped. After opening up the fittings and line ends things worked better but I never liked the live oil line on the dash gage so I switched it out for an electric Isspro EV gage. Now pressure is up instantly and things are ok. Till I over heated the motor whena freeze plug poped out... Even thats being fixed so all is well here and I have all the time and specs for what a motor looks like at 5200 miles. I will be shimming the oil pressure spring.....

EZ, I also agree with the "step back, regroup, then go for it"
There's an answer somewhere, but I don't have it.
But lead etc sorta sounds like bottom end to me.

Don't rule out an oil gallery plugged somewhere or something. Hopefully not.
This example is extreme, but I had my original engine "shade-tree'd" overhauled several yr. ago. Got it back & ran it about 1 yr....had off & on funny OP, slow OP buildup at start, etc, etc. Finally tore into it. There was tons of silicone in pan, pick-up tube, oil galleries, everywhere....my engine was oil starved off & on bigtime.

And Motorcraft, Rotella, Amsoil are all good oils. I use Delvac myself from WallyWorld. Actually, as hi-miler an engine as I have, I've considered just using WalMarts own brand 15w-40. Wouldn't be afraid of it really.
As for as engine flush, as stated above, sounds to me like you been using a pretty hi detergent oil along with a somewhat newer/tight engine & your engine is already pretty clean enternally.
This doesn't sound like yours, but if an engine is sludged, my opinion is be somewhat careful of engine flushes. Sludge needs to be "flushed" sorta slowly.....over several oilchanges. Several year ago, friend was running Delo 300 or some lower detergent in a semi 350 Cummings...he changed to Delo 400 Hi detergent & made about 1000 mi to middle of nowhere & lost oil pressure....turned out to be clogged/plugged oil filters. If he had run Delo 400 since new he wouldn't had this happen.
I've used 1 qt ATF in a sludged gasser engine....coming up on oil change, then add the ATF & run 50-100 miles or so, then do the oil change. Do this over several oil changes & slowly clean up the engine.

Factory OP guage....yeah, they get funny sometimes....come & go....throw chills thru your heart sometimes. (personally, I think they should be outlawed!!)

Anyway, hang tough......I think its kinda minor at this stage....

Thank You guys, I hope it is minor too. Today I changed the oil and put some rotella 15w40 that I will run for 500 miles and send a report to blackstone to see it comes back with, if the results are good I will go back to motorcraft oil as I used from the beginning.
