Rebuilt engine leaking like crazy... need quick help
Trying to finally get this thing started, it is hemorrhaging oil when I prime it.
Pressure is fine and oil gets to the top but it is GUSHING from the oil filter. It seems as if it's coming from behind the oil filter.
I have verified the block is dry above the filter.
I installed a Delco filter and a new Oil Filter adapter... what's back there that can leak this bad?

Ok I think I may see a problem. It has an oil filter bypass similar to http://www.summitracing.com/parts/SE...-900/?rtype=10 installed.
Correct me if I'm wrong but it shouldn't be a BYPASS installed there correct?

That bypass/adapter combo IS the normal stock type deal. So, nothing wrong there if that's what you want. But the filter must seal up oil-tight to the block's oil filter gasket surface. Take a look at that and see what's going on there. Is there any chance that the particular filter you are using is somehow bottoming out on the adapter and then not sealing up against the block properly?

sounds like the oil filter is not sealing.

It's possible it may be bottoming out, there's a pretty thick gasket on it (only one, checked for that) and I can crank it down pretty good but can't really get a good line of sight to see if it's seating fully.
I just took it off and the filter didn't blow it's gasket or anything and the leak is definitley coming from here.
Going to try cleaning both mating surfaces well before putting it back on.. wish me luck!

I'm not sure what that particular filter's threaded area looks like. Does the threaded area protrude outward? If so, then it will bottom out sooner, and is almost certainly your problem. If that is indeed the case, then get a filter that has a more level threaded area, rather than protruding. That difference will buy you some clamping distance.

I have no idea guess it'll just be trial and error.

Is the plug in the block above the oil filter. This is where my oil Temp sending unit is located on my 1982. If this is a small block, install a ACDelco PF1218 it will fit all the way up to my last block made in 2006 330 HP.
