Re: H-I-J '76 Nova re-fit.
I have some theories, but won't know till I get there and start looking further. I'll recheck the pick-up but I'm pretty sure with the 1 piece gasket it was 1/2".

Re: H-I-J '76 Nova re-fit.
The little plug I mentioned is down in the block under the rear cap. It presses in there and closes off an oil passage. You'd still have oil pressure even with it missing.
A good shop would knock that plug out to boil the block and sometimes it never got replaced. A high oil level in a stock depth low capacity pan is not a good idea but with a windage tray it should not have caused this. The pickup being slightly higher than ideal is not a big deal to me either.....unless oil is trapped up top and you generally will see oil pressure fluctuations if the level was to low and pump was starving..... Think about just how the oil in the pan is moving around in a wheelstanding car....sitting on a dyno its not under any of those forces.... Small blocks "like" to kill #5 & #6 rods more than any others.....Don't ask me why ….. I hope you find a cause and hate seeing stuff like this....but it happens unfortunately.....

What are you running for oil filter, can't see in your pictures on dyno.
Need to be a racing filter. Have see racers have trouble with regular street filters. Larry |

Re: H-I-J '76 Nova re-fit.
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! Regards, HB2 Dissident |

Re: H-I-J '76 Nova re-fit.
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.....
