Default Re: Coolant Vent Line Alternative

First start on Friday
Cam chains and lifters are pretty noisy until oil pressure builds up which is normal.

Don’t you hate that, especially since it takes 2-3 minutes to fully resolve.

Just was thinking about this today.. What size fittings did you use with the 5/16" line?

What did you use to bend the lines?

Since I still have secondaries, I am thinking off adding these on the coolant tubes as I am not sure I have room for them under the plenum.. Espcially with my LS2 coils

1/8 “ NPT 90 degree fittings in the injector housings.
Simple hand tubing bender from the local tool store.

I basically had the same setup on my stock motor run in 5/16” hose which still had secondarys.

Had a shop in Chicago do the 4.125” closed deck cylinder liners and local motor machine shop do the balancing and valve seat work. And I did the rest.
