Frequently asked questions

Do I need to run the steam vents on an LS swap?
Yes. Skipping them is a common cause of hot spots and cracked heads.

Where should the line go?
Usually to the top of the radiator inlet side or a header tank, above the engine's highest point.

Tucks tip: don't skip the steam lines on a swap. It's a ten minute job that saves a set of heads.
