does anyone know the valve stem diameter of a b18b1? i know for a fact the b18c is 5.5mm and im just trying to confirm if the b18b1 valve stem diameter is the same before i go trying to use these titanium keepers i bought and end up dropping all the valves into my cp's

 

aww man don't ruin that dart block. I'm not sure but I would call a company or visit a shop that stocks them.

 

Thanks and im tryin to doublee check everything before putting it together. The diameter is the same for anyone wanting to know I was digging through some boxes and found my ferrea seals and the packaging says 5.5mm and are for an ls. The only thing that threw me off was on the crower valve locks it said vtec so I was kinda worried.

Mods can close this thread.

 

Lol I don't think there's any mods in tech. I think this is the bastard forum/tech lol
So you saying the diameters of the valve stems are interchangeable from all b series? Or just the keepers?

 

Im not sure on all b series but the valve stem diameter is the same. For both the b18b and b18c

 

negative b18a and b18b is a 6.6mm stem same size as the dohc zc heads, all other honda heads have a 5.5mm valve stem

 

So why does the ferrea valve seals say 5.5mm that I have?

Nevermind found what I needed apparently horsepowerfreaks are a bunch of dumbasses and don't know the difference between a b18b and c when ordering parts.
