Hello everyone! Proud new owner of a 1970 240z. HLS3007326 to be exact! A beautiful car. This is my first Datsun ever, and let me tell you, I am in love. I'm at work right now but I will add pictures asap! First off, the car has a rebuilt F54 block with a P79 head, both have less than 6000 miles on them. Issue at hand: The PCV tube coming off of the block is capped off with a freeze plug, the crankcase breather has quite a large hose that is venting directly to atmosphere and seems to have excessive blowby, which is pretty stinky (which is funny because one of my top reasons to buy this car was no smog checks!) and this can lead to ring failure I've read.. I've done my fair share of research on this and seems to point in the direction of a catch can of sorts. So, my issue is there is no PCV tube coming off of the block, at all. just capped. I cannot find this tube online anywhere (I can find the pcv valve and hose, but not the tube). Also, if and when I do find this tube, will venting this along with the crankcase vent to a catch can solve the problem? Will venting the PCV and the crankcase reduce the blowby? Why would the engine builder cap this off? Thanks in advance to any insight and help you can provide. I added a couple pictures
