914World.com _ 914World Garage _ Rocker box vent tube

Posted by: Gearhead1432 Apr 25 2010, 07:41 PM

I just pulled the drive train out of my 914 last week in preparation for some hell-hole repairs. While I was cleaning the engine up I found the vent tube in 3/4 head was missing all together! There was only a hole where it should have been. Are these vents necessary? I've noticed that some 1.7 heads have them and some don't. I don't know if I should try to replace the tube, replace the whole head, or just plug the hole and call it good.

Thanks,
-Rob

Do a search. There was a 3 or 4 page heated discussion on vented heads about Jan. I'll find it later but searching from my phone isn't very easy.
