Stock Heads otherwise
I recently broke a valve spring on the #7 forward intake valve. Thankfully damage was limited to just the spring.
After replacement of all three #7 springs and without the roller cam followers installed, I performed a satisfactory compression leak down check of 77/80.
Installed roller cam followers, and now I’m getting 0 compression and I can hear blowby in the intake and exhaust.
Is this caused by the lash adjusters being pump up a bit? Will they automatically adjust back down once I fire up the engine? Or should I attempt to pull them out a bleed them down? Thank you!
(Also, I apologize if this has been answered a million times, I get an error every time I “search”)
