saw it mentioned in the cl***ifieds and wondered about how to do it, somebody tell me? something to do with a freeze plug...
I THINK its a 1 1/4 freeze plug... I just threw my extra one in a box somewhere... but now you have to put breathers in your valvecovers... or run baffled-breather hole Mullet-rock morosos... please, get red or blue anodised ones, theyre kewl! Or run a pcv... naaaah.
I ditched the draft tube and stuck a breather tube in both ends. One in the intake in the front and the other in the back of the block.Valve covers are still solid with no breathers.I think it breathes better and doesn't blow out the front one.
ditched it...used an expanision plug/ the rubber ones at autozone. and even had better oil pressure it seemed???
rubber expansion plug eh? i can get those at work, and I already have breathers in the valve covers. BUT when I first got this car, the road draft tube was stopped up, and oil sprayed out fo the dipstick tube, but as soon as i cleaned it out it stopped. It had the breathers on it then as well and i don't want that to happen again.....
A trick I learned from the guys at 348-409.com is to put a freeze plug in the hole in the back of the intake after drilling it to take a rubber grommet. In that rubber grommet they install a PCV valve with a hose running to the carb base/plenum. That way, the PCV is hidden under the distributor so you don't see it but still vents the crankcase.
just ran out and looked at the car, and the tube is in an easier spot to get to than I thought. Maybe I can add this to my list of things to do today, but how do you get the freeze plug in after you drill it out? Don't they usually have to be pressed in?
Not related to your engine but a good tech article on the In-line chevy engines about pcv installation. inline
