A follow up to "oil starvation issues" thread

[grant6395]

[QUOTE=joespanova;499472]So I started pulling the engine down , pulled pan and its full of bearing material. One by one the rod bearings looked like they were getting restricted oil flow but not as bad as I 've seen. The rods looked fine.

The main bearings on the other hand WERE COMPLETELY DESTROYED , to the point of the 3 center main caps getting "blued or blackened" .
As you can imagine I'm angry , pissed and any other verb you can come up with.
This isn't my first small block , to say the least...............but it IS my first Dart block ( Little M sportsman ).
The main caps no longer fit tight in the registers either, BTW.
Now here's the really pathetic part.........THESE BLOCKS ARE SUPPOSED TO BE PRIORITY MAIN OILING? WTH is going on here?

Main clearance at .003 , crank is straight ( BRC crank ) new Melling pump etc etc. The plugs in the block at rear are not plugging any passages...not that I'm aware of. The sump had 6 quarts.

Now how in the he*lL can a priority main oiling block starve the mains?

You can bet I'll be calling Dart in the AM.[/QUO
its definatley lack of oil.Severe windage or you are pumping all the oil upstairs..I resonded to your issue on another forum.When you get it repaired,if your still using the same cam and lifters,put a drill on the pump and see if your getting excessive oil to the top,starving things down below.restrictors may be order.Seen this movie plenty times before.Not the blocks fault.

Then why aren't the rods that bad.............in fact some of those bearings looked almost reusable. No bluing on rod bearings ......some shiney but thats it.
The rods get oiled through the crank..........
Grant.....I did see your other posts and point well taken . I used restrictors in the old Gen 1 stuff and still had starvation issues...........
HOWEVER , starvation never happened as fast as this............ 1RUN? ........Maybe 2? I mean I ran it TWICE and trailered it. It had great oil pressure in the shop......
A new pan , pump and accumulator on the way. I will definately measure lifter to bore clearance ( Carl ).
I want to know about the oil band lifter issue? I'm using Comp plus .300 std rollers. No fancy rollers here.

Crank bent? Just my thought.

Have the crank mainline checked.

Have you had crank wet magged,cracked crank will flex and wipe mains out.
Wet magnaflux uses black light to see cracks.
I mag EVERY crank that comes through the shop,is figured in price of polishing or grinding,
you may mag a dozen and all be good and then next dozen have 6 or 8 cracked.

Mike I'm going to look at that REAL close this time..........

[carl hinkson]

After talking to you on the phone I think your headed in the right direction.

Talk to Jake Stelter or google his his name and add drag week.

Listen to this post.

Are you positive that you had .003 on all mains? Have a circle track friend that had exactly the same results that you have had with the same little m block. His engine builder missed it twice and now he has a new builder.

I've never heard it referred as "wet mag".......but I believe that's what you or Mike mean.
And yes , I have the option of using traditional mag or FPI.
