I have a 69 396 chevy jet boat engine. On one side the breather has tons of oil blow by. Does worse the more rpms I push. I have changed the gaskets because they were old, and also put baffled valve covers and breathers on both sides. whats wrong what should I do.

  1. A simple compression test will show which cylinders are worn.  Blowby is caused by worn or broken rings, cracked pistons, or scratched cylinder walls.  


  2. blow by is caused by faulty rings , time to rebuild the old girl.

  3. rings need replacing ,

  4. BIG BLOCKS ARE NOTORIOUS FOR VALVE GUIDES LEAKING AND THE SEALS..  ON A 396 YOU'VE PROBABLY GOT ALOT OF HOURS ON IT AND ITS GOING BY THE RINGS TOO.   EASY FIX NOW BEFORE YOU DRY IT UP UNDER A LOAD... THEN SHES AN ANCHOR...  REBUILT IT BEFORE YOU KILL IT .
