I have a two -8 vent hoses to a puke tank and breather.
I run one line from each valve cover....do you reckon thats enough to vent the crankcase?
Yes, that sounds fine!
The root of my problem was the gasket issue- The holes I poked were way too small! Once I cut the gasket, everything was good to go with two 3/8" hoses (I think one with a small breather would have probably sufficed). Do you have a vacuum port you could use for EGR?
I ended up cutting both gaskets, running one 3/8" tube to a small cheapo filter, and the other to a catch can with a pan e-vac pulling on it. I am very impressed with the pan evac- pulls 1 in/hg at idle, and the gauge touched 4+ in/hg when free revving. When hooked up through the catch can to the motor and the gauge on the far port, i had a 0.5 in/hg vacuum at idle. I'm very pleased! Though, it might be pulling too much as I probably pulled a cup of oil in about 100 miles of driving yesterday! Though, it's all black oil, so it's probably better that it's out.
Update on clutch issues:
I re-routed the clutch line and re-did / tightened all connections. Then, I bled the clutch a few different ways. First, I hooked a clear line with a 90 degree fitting (mityvac rubber fitting) to the bleeder screw (angled so the fitting was the lowest point). I ran the clear hose all the way up to the reservoir. I started by only opening the bleeder screw when pushing the pedal to 'fill' the clear hose. once filled, I left the bleeder open and just worked the pedal for over an hour. I then closed the bleeder, and went back to only opening the bleeder valve when pushing the pedal. Then I would 'pump up' the pedal 20 times, hold it down, and open the bleeder valve. After all that I closed the bleeder, drilled a slightly larger hole in the reservoir lid and put it on, and pulled a 18 in/hg vacuum (mightyvac) on the system through the bleeder hole. Left it overnight, and it was still 18 in/hg in the morning. Bled it a few more times conventionally (open with pedal push, close at bottom). After all that, the clutch worked better yesterday for the 100 miles I drove, though I did have fade at times. I stopped at the auto parts store and had a lot more pedal when I came back out, so I definitely think heat is playing a factor. I got caught in stop and go traffic yesterday, and the clutch would not 'pump back up' hardly at all during that time.
I'm going to see what I can do with some 2000* heat shielding today.
