RE: the need for add'l PCV breathers for a 5mgte, I finally got a look at a 7mgte oil breather layout. To do the same for a 5mgte, it seems as if I could use a T hose connection for the intake side hose to connect the throttle body and intake valve cover, but what can be done for the exhaust side valve cover. Could I drill it and put a fitting in it making it like the 7mgte?
I know Phil used a hole in an oil cap to rig a vent to air with a catch can. Did that work well enough?
What would be other ways to add breathing/venting?

ok, the best thing to do would be add another fitting but put it on the exhaust side valve cover. then run a hose from each one to a catchcan. dont rout it back in front of the turbo, that will just cause oil buildup in your intercooler pipes. also, it is best to plug the intake manifold side as well, no since in burning the oil and helping build up the carbon on the pistons and valves.

Yes Dave, I am in Vegas.

I just had another idea. How about using an extra intake side cam cover on the exhaust side. It already has the breather outlets and you would have an extra oil fill. It looks like the holddown screws are in the same positions. Does anybody know?

I don't see why it wouldn't work. You could fill your oil after a change twice as fast too! as for the T into the TB, just make sure you have a check valve in there, as you will loose some boost through it. I would just run in it directly into a catch can, tho. The 5m shoots a lot of oil out of there. Personally, I just ran the intake side PCV. Never had any crankcase pressure problems.

Here's the smog friendly way of hooking it up:


The arrow on the one-way valve shows air flow. Also, make sure you put one of these between the manifold and brake booster,if there isn't one there already (you can use the one off a mk3). It's odd, my mk2 had one already. But everyone else I've heard of hasnt :?

Here's how I did it:



I suck at using MS Paint, but you get the picture. If you want to add an extra PCV port (with another valve cover or what have you) just add in an extra T into the system.
