Just inside of the #5 Cap (normally covered by the valve cover there is a
pretty good stream of oil shooting strait up (about a foot).
It seems like the oil is coming from the squirter area and then shooting
strait up as opposed to towards the cam (possibly starting toward the cam
then
hitting the lip of the cam and turning upward)
The squirters are supposed to direct the stream towards the cam lobe /
follower junction area. On later heads that came with roller cams, the
squirters were eliminated as there was sufficient oiling for roller
followers without them. However, there is nothing wrong with having them.
If the oil stream from the squirter is going someplace other than the lobe /
follower area, then there is either dirt or other foriegn substance in the
hole, or there may be a distortion in the way the squirter was cut. Since
this is cap #5 and that is on the end, and it is the end ones that gets the
anaerobic sealant applied to prevent leakage, there may be a small piece of
the sealant in there misdirecting the stream. While it is wrong, since
you are using a roller cam followers, it is not something that should
cause a problem.
All of the other squirters are spraying away and the oil pressure (using
the
dash gauge is fine).
Also all of the lifters are hard as rocks and show no signs of breaking
down.
Although, I have not found any formal way of testing and you really cannot
remove them at full temp.
One thing that has come up in discussion before though is the lifters or
lash adjusters. Folks commonly buy the MP anti pump-up race lash adjusters.
Often because they find new stock ones at the dealer are far more expensive
than the MP units. However those lifters were developed for race cars that
are used on a track only (road racing).
Road racing engines at the time used (and many still do) a straight weight
race oil like a 50w. With stock lifters they would pump up at high rpm
because the stock lifters were designed with clearances to use a lighter
multi-viscosity oil, like a 10w30. So Mopar brought out a set of lifters
that had slightly more clearance so they would not pump up with a 50w oil.
If those lifters are used in a street engine which uses a thinner oil, there
may be noise issues. Some folks have a problem with them and some haven't.
But the MP lifters were never designed to be used with a thinner
multi-viscosity oil like a 10w30 or, as you use, a 5w30.
So if you are using the MP race lifters and having valve train noise
problems (especially once the engine gets hot) switching to stock lifters
should fix it. There is no difference between the stock lash adjusters
used with slider cams and the ones for roller cams.
