Van Buren,
Arkansas
Recently I finished my first engine build here's a quick run down.
Oil port
Balance shaft delete
Scat H beam rods / stock 2g pistons
Ring gaps .020 top and .023 bottom
Block and head are stock otherwise
New valves, guides, and seals.
Maybe 5 miles on build so far.
Here's the issue I'm experiencing quite a bit of blowby and oil seeping through the bolts on the valve cover.
I noticed the PCV was not in great shape.
I do have the PCV as well as the left side port running to a catch can.
Thinking that it may be backing up there somehow I unplugged the line to the can and let the PCV breathe free and still same issue.
I do notice a steady puff, puff, puff of blowby out of the side port on the valve cover sorry I have no other way to measure it.
My initial impression was that I had gapped the rings too large but I am confused since I read this gap is common and even larger gaps still.
Apologies for the wall of text this is the best I can describe it. Again it's my first build so I may be missing something obvious.
Any advice would be great, thanks in advance.
