Morel Lifters understood, thanks Chris Straub !!!

I hope I have a much better understanding of my Morel Lifters thanks the Chris. I installed them and had no oil to the top end, just like I've read. I gave it 2-3 minutes and still nothing. This was completely opposite of my old Comp Cams Solid Lifters which oiled ALL 16 in 20-30 seconds, and that was without rotating the crankshaft 1*. Before modifying the Morel's, I made a call to Chris. He explained it may take 40 minutes to get oil up top, especially with my 20-50 Penn oil. Sure enough, after about 6-7 minutes of my 1/2" Milwaulkee drill at full tilt oil started showing up on a few rockers. It took me about 45 minutes total, rolling the engine 20*-30* every 6-7 minutes before I got oil out of all 16 rockers. Oil pressure on the gauge said 60lbs with the drill. This is on a SVO Block with no lifter bore modifications.

I'm hoping this may be a large part of my lack of oil pressure after a 20-30 second pull at 6,500 rpms. My o/p was "OK", but after a longer pull it would drop, I'd lift when it got around 10-15lbs. It would return to decent o/p after a couple 5-10 seconds. Leading me to believe I was pumping all my oil up top, and after a few seconds the oil pan would refill. Chris and John have told me the top end needs a lot less than I thought, guess I'm gunna find out. Just thought I'd share my experience.

Glad I could help.

So do you plan on going through that ritual every time you start it cold?

X2 45 minutes with a drill is a bit extreme don't ya think ?

We see it with the BBC on builds also. A Dart block to prime with a 1/2" milwaukee drill takes at least 35 minutes.

But does it damage the engine with cold starts?

Or is it better to just take the dremel to it and cut a groove?

Once the engine is primed then oil is present in the entire system. The oil pump is driven by engine rpms.....HUGE difference over a drill even if it is a Milwaukee.

Very little oil is needed in a rollerized valvetrain. Oil is needed in crank and rods.

Only problem i have experienced is push rods. They tend to have a short life without oil present. Healthy spring pressure of course.

Old or new Milwaukee drill ?

Here is he old version.

That's some serious extremes, 20-30 seconds to 45 minutes. Just saying

That's Keith Fulp's big dia. lifter on the right.....it's just a kitty kat scratch saves 45 minutes.

I'd need at least 2 of the old ones to make it 45 minutes with a new one?

I'd agree with Chris in a prostock type application, where valve train maintenance is taken to the extreme.

But for a sportsman application id want a little more oil on my top end, it helps keep things cool and last longer IMO.

Piss on that.

X3...or one of the old ones and a die grinder with a custom bit
