My question concerns the recommendation not to torque the bottom row of
cylinder head bolts on a Rover 3.5L V-8, to prevent blow-by into the
crankcase below the valley pan. Later Rover engines deleted the bottom row
of head bolts, so they realized this to be a problem.
My problem is that we just rebuilt my MGB-GT V-8 engine using Fel-Pro
Permatorque head gaskets and left the bottom row of bolts at ~35 foot-lbs,
as opposed to 65. Now I have a very slight oil leak around the rearmost
bottom bolt on the RH bank and the frontmost bottom bolt on the LH bank.
The leak is appearing at the gasket joint and is evident on the machined
bosses immediately below the joint, right below the bolt locations.
Since this is a concours restoration, I would rather have no leaks and worry
about blow-by at a later time.
I'm tempted just re-torque the bottom row back to the recommended OEM torque
setting, but I might remove the bolts and re-seal the threads with grey bolt
prep before doing so.
Any thoughts on this?
Cheers,
Paul Kile
