jojothemonkey Posted February 14, 2008 Share Posted February 14, 2008 Ok so I know this has something to do with the coolant in the engine block. But with all of the pics I had taken of the engine prior to pulling it apart I don't have one of what this goes to. From what I can gather it may be coolant bypass or recirculation line. I'm not sure. I will not be running ac/heater and already have the two hole plugged on the passenger side. This is at the front in between the exhaust manifold and where the ac compressor would go. When I pulled it out, found that it is not threaded and I don't really want to thread the hole to plug it. Quote Link to comment Share on other sites More sharing options...
m1noel Posted February 14, 2008 Share Posted February 14, 2008 Its a crankcase breather tube. No coolant here!. Plugging it may cause problems. Mike Quote Link to comment Share on other sites More sharing options...

jojothemonkey Posted February 15, 2008 Author Share Posted February 15, 2008 That kinda clears things up. Then that should be routed back into the intake manifold with the pcv valve. Is pcv valve required? I have removed the fuel rail and everything else. Now all that is on there is just a pallnet fuel rail and fittings for the vacuum lines.

OlderThanMe Posted February 15, 2008 Share Posted February 15, 2008 Mine is just routed to the crossover tube inbetween the SU intake manifolds. No valve at all. Quote Link to comment Share on other sites More sharing options...
zercs280zx Posted February 15, 2008 Share Posted February 15, 2008 I'm about to finish up my build and I have some questions of how to handle this PCV line out of the block.... I have an L28 with a custom intake and EFI (the previous setup had the PCV line going to the OEM intake, my custom intake does not have this input). I found a line that I can tap into in the Throttle Body (after the flap, from the bottom). I was planning on plumbing the PCV hose there and let the gasses get sucked into the intake (like it was). Is that a suitable location? I would rather not drill into my intake if I didn't have to. Also, does this system require a PCV valve or can the hose just dump in there? Are there any other ways to run it? I don't particularly like the idea of recalculating these gasses back into my engine, but it seems like the best system and from what I understand you need vacuum to ventilate the gasses. FYI: My valve cover is being ventilated into a small K&N breather. Quote Link to comment Share on other sites More sharing options...

Careless Posted February 15, 2008 Share Posted February 15, 2008 Get a small air compressor oil-air filter that is filled with desiccant pellets (blue ones), and tap that hole and run a barb fitting run a line from that spout to the IN on the filter. Put it inline with the breather on the VC, and when the pellets are pink, change them. you'll get less gunk, and oil and fumes in your engine, and you'll soak up the crap with the desiccant pellets, which can be replaced quickly and easily, and pretty inexpensively. Good filters have a pass through on the top (from one side to the other) with a hole at the bottom for draining the unit. (so that's 3 holes) Put a petcock there, and fill the unit with some steel wool (the springy kind) instead of the desiccant pellets if you want., and you can see how much oil passes through, and you can drain it when it's full. The steel wool just helps to keep the oil closer together, rather than the possibility of it sloshing around while driving, and meeting with the hole that is creating vacuum. You can read about this stuff on the g00g. Quote Link to comment Share on other sites More sharing options...
jojothemonkey Posted February 16, 2008 Author Share Posted February 16, 2008 Thanks for the input. It dawned on me a few hours after I had posted a reply to do a search on what others have done for this and Proxlamus has a thread going on with a bunch of good info in it ( http://forums.hybridz.org/showthread.php?t=121590 ). What I have found is that one of three things happen. People put an air filter on it, run a catch can or do some sort of pcv setup. I think just for now I will put an air filter on it and continue to focus on getting the car running. Quote Link to comment Share on other sites More sharing options...
