Todd and Autumn,


Sorry to hear of your engine problems on the dyno.


Might want to check a few things in the oiling path.
A) oil pump pressure relief valve piston to bore. If it sticks open the oil is returned to the sump and kills oil flow to passages.
B) oil filter adapter bypass should be sealed off. IF open it returns oil to sump and supplies unfiltered oil to engine.
C) Plug under rear cap does the same as B) above.
Good Luck on finding the offending issues so you can continue.
D) all the above depends on a properly clearance pump and often out of the box, they are far from it. Although that is probably not the problem, good time to check it.



Hang in there!

Nothing wrong with using a 1061...…
That filter has no anti drain back valve and is fine mounted vertically.
A 1060 does have the anti drain back flapper valve.....needed for filters mounted horizontally....

Wix makes Napa filters and they just add a 5 to the number to denote its an oil filter.....

51061 R is their racing oil filter....and I use those...and have used them for years with no problems.....

The only filters I know of that had issues was Fram…..and I saw it first hand and won't use one even on my road vehicles.....
