OK to only run one port on the endyn catch can?
I can only get one of the plugs off the back of the block. Can I run one hose to the catch can from here and drain it back to the same one and plug the other nipple on the catch can?

Re: OK to only run one port on the endyn catch can? (JMinSi2000)
Doesn't sound too great....but it's better than nothing. I dont have the oil seperator on the back of my block so just one of the hoses will vent some crankcase pressure. I figure I'll have drainage problems from it not being high enough anyways, so i'll just pull the hose on the bottom once a week or something.

Which one can't you get off? Jim at Z10 assured me that the only one you need to use is the passenger side port. Using the other port, according to him, is unnecessary and is the cause of people having too much oil enter the catch can. I'm using both, but considering just using one in the future. Here is a link to a thread where he explains this. Just scroll down and read the post by Z10Jim:

I just read that link for z10's explanation and it doesn't match with what I was experiencing with my setup.
Jim says:
"There are 2 crankcase vent passages that lead to the cylinder head, and only one on a GSR head is truly a vent the other has oil draining down it (this one is on the driver side or closest to the alternator)and should not be used for a vent to a catch can"
Yet my passenger side port is actually the one which consumes most of the oil. The driver side vent line doesn't have the same problems.
What is it like for you?
Remember how I mentioned that my passenger side line looked like it was having problems siphoning oil a while back? I removed the line to inspect and it actually didn't have any oil siphoned in it, just a thicker thin film of oil on the inner diameter to give the appearance that it was ingesting oil rather than just oil vapors.
This is making me think that alot of these individuals who are having problems ingesting to much oil with their endyn catchcan have excessive blowby problems creating this. I built my own motor and my leakdown numbers were quite good ranging from 4-6% across the board.

I don't know because I haven't tested it yet. I have both lines hooked up, with the "T" and drainback going into the passenger side port. Apparently, Endyn's instructions tell you to use the driver side as the drain, but after searching their forums I found the opposite was recommended when people were having problems.

What do you mean by siphoning oil? Drainback?
Before I had a drain line hooked up, my can overflowed farily quickly, and had to be drained daily. I'm positive that I have excessive blowby, but still believe what Jim at Z10 said makes sense. After all, that's very close to the location of the stock pcv black box. I will test this before my engine build on the block I have now. Maybe I could just clamp the driver side line, clean the filter and see what happens. Right now the setup works, but the filter still gets oily and sprays a little bit. Wal Mart sells 2 packs of white wrist bands in the sports department for $1.63 that fit around the filter and stop the misting, and I just put a new one in when it gets oily.

What i was saying was that originally I was under the impression that the passenger side line running to the catchcan was occasionally siphoning oil when in actuallity when i removed and inspected it wasn't. The Passenger side line closest to the tranny was just carring the bulk of the oil vapors so it discolored the inner radius of the tube quicker. I have had this catch can setup for almost 1 year now and have watched the 2 lines on a daily basis monitoring them getting progressively darker and darker as oil vapors continually discolor the inner radius of the clear tubes and coat the walls with a thin amount of oil.
What I can clearly see is that the passenger side line has the most oil vapors going through it because of rate of oil film buildup in my clear lines. This contradicts what Jim says about staying away from the driver side port because it is the source of the large oil induction into the catchcan.
Maybe If I remove the drainback feature it will cause the opposite reaction? I am going to by some new lines and test various different setups and let you know. Let me know how yours turns out.
If you lived close by I would love to do a leakdown test on your car to see if you do indeed have excessive blowby passed your rings. I would suggest finding someone around you to do a leakdown test in attempts to isolate the problem.

Re: OK to only run one port on the endyn catch can? (dasher)
I see what you're saying. Is it possible that oil vapors carrying more airborne contaminants on the passenger side would cause more discoloration and coating, and on the driver side, the amount of oil is more likely to flush the tube clean? I'm afraid to remove the drainback, but that would also make sense.
I live in Pennsylvania, or I'd take you up on the leakdown test offer. I bought a Tavia leakdown tester a while back, but don't have access to an air compressor. Soon I'll be exchanging my B16 for a new block anyway, but will close off the driver side line when I get a chance to see what happens. I'll let you know how it turns out.

Naw , I inspected both tubes ... its just a thicker film of oil and whenever I clean out the tubes the passenger side builds up the layer of oil quiker indicating to me most of the oil vapors are coming from the passenger side and the driver side doesn't have any problems ingesting oil.
