<VV> WC: Possible Source of Oil feed problem?

[Bob Gilbert]

Hi James,

The 3.1 build is going well although having not done a major build for 20
years I am a bit rusty and I find myself constantly referring to the
manuals.

Only two problems so far. I was unable to get the cam/crank timing marks
perfectly aligned with the split in the crankcase. They are off by about
1/32 inch so I think the actual index punch mark is a hair off as everything
else checks out and it is way less than a tooth width. The only gotcha was a
badly broken differential snout when I split apart the existing motor. The
split washer was gone, the seal was just about destroyed and there was just
barely enough surface for the release bearing to move on! I had a spare
snout but I'm always nervous about re and re'ing a differential or anything
with gears for that matter! Getting everything set up right is as much as
black art as a science IMO! J

Other than that the heads are going on today and by the end of the day
everything should be on the motor except the sheet metal.

Regards,

Bob

Hi Bob,

 

I have oil feed problems up all my pushrods, but all my pushrods are brand
new heavy duty, super clean units from Ray Sedman.  I wish it was only one
or two.  On that note, I always shoot a stream of brake cleaner up through
the pushrods to make sure they are clear before installing them.

 

How is the build going?

Hi,

I just made an interesting find while building my big block for my UltraVan.
I was installing the LH bank set of pushrods and found that 2 out of the 6
rods had plugged oil holes. In the past I usually just did a quick visual
check but this time on a whim I decided to run a piece of soft mechanics
wire through them. One had a partially plugged tip hole and one had a piece
of crud inside the rod! I mentioned this because some time ago I seem to
remember hearing about some guys having problems with oil feed to their
rockers.

Certainly something I will check for in the future.

Regards,

Bob
