we don't run valve seals on our high-ish hp engines...
the only time a (turbocharged) diesel would 'suck' oil through the (worn or non existant) seals would be at idle...if then
valve stem wear is pretty ridiculous on these engines...so removing the seals can increase lubrication of the stem...which is also why even our "stock" engine's get bronze valve guides...
less wear...less valve stem/valve face "rock"..a more square seating for the valves/seats...more longevity.
if it isnt broken....dont touch it.
im going to attempt these while changing out my valvesprings and pushrods.
any vendors on here that sell them?

I'm curious to know why a turbo diesel won't suck down oil at the seals but gasses do?
Attempt? It's pretty strait forward. Old one out new one in

Well.... one has a constant and varying vacuum on the intake runner typically (gas engine) - the other might have a vacuum at idle, but it quickly becomes neutral to positive pressure as the turbo comes on... (turbo diesel) without the vacuum there is nothing in the intake runner to suck the oil down out of the head. Its really more of a difference between naturally aspirated and forced induction - but most gas engines that people are familiar with are naturally aspirated and most modern diesels that we care about a forced induction.
Never done them before.

Awesome thanks guys.
