Garner, Beautiful work machining the pulley! What's up with the bike in the background of the engine hoist/incline photo?

mike, you should check on the nasioc forum for these types of questions. there's a lot more familiarity with this part over there. also could try scoobymods or clubwrx. hth, luke

Mike, Could the mystery hose be the intake manifold vacuum-assist line? I think that the BOV is actuated by two mechanisms that are complementary to each other: 1. Sudden transient pressure increase inside manifold plenum (IC outlet) means throttle plate has snapped shut for a gear shift. This causes the BOV to open up and vent boost back to the turbo air inlet... 2. The BOV is held open and assisted by the vacuum INSIDE the intake manifold, created when the throttle plate closes. Anyway, I think that's what your mystery hose is, the intake manifold vacuum-assist line. And I think the other lines does return (vent) boost back into the turbo inlet to recycle it. Luke

Somehow a large quantity of blow-by gas is escaping past your rings. I would do a compression check to find out the condition of the rings. Then, if they are a little low, sealing the rings with a little oil and seeing if the pressure comes up. If that happens, I would suspect leaky rings allowing lots of blow-by, which contains lots of oil, and will trapped in the air filter, or airbox. Or more simply, perhaps your PCV inlet hose (the one that connects to the PCV valve itself) is clogged or otherwise restricted? This would cause gases and pressure to build and back up the system, eventually causing oil to come out the entrance to the system - the airbox.

not to go off-thread here, but that's the spirit of what i love about this board and interest: it doesn't cost an arm and a leg to buy in! this board has a pride in diy, and keeping things inexpensive and reasonable, which I really appreciate. old subes are a hobby, an interest, an activity, and a passion that you don't have to spend a lot on, and i even think that it could be considered bad form if you did. btw, epoxy should hold against the heat. my brother epoxied the coolant overflow pipe back to the filler neck. it held against the heat, but was never pressure proof (different issue). Luke

FWIW, Now we know what that CLICKING sound was! Thanks.

Mine's an '88 also, and it puts out compression readings of 170-180. Smashed rad is no problem, you'd probably need to change it out anyway by this point. Also, unless he was in the habit of racing the engine, no tach isn't a problem. My DL doesn't have one, and it's easy enough to shift by ear. I envy you guys...getting all these $100-200 deals on EA82 cars. Can't find any in this part of the country...rust ate them all, I think.

Probably not, but then again this sounds like something my life usually lacks: PURE ADVENTURE. I'm not sure which of the constraints makes it more exciting: the possibility of jail time (always high up there), the possibility of highway breakdowns, or the running-out-of-money factor. Sounds like a truly great trip, and well worthy of the film used to capture it. Good luck and Godspeed! Luke

Or how about sticking a piece of cardboard in front of the rad? Should slow down airflow and drive heat up.

Well, wouldn't the non-AC engine be missing the driver's side clutch fan and shroud? Non-AC models only have a single electric fan on the pass. side. AC models have an additional left-side fan driven by the water pump pulley. I imagine that additional airflow helps the AC's radiator, which you can see directly in front of the engine's radiator.

I agree. Those two small outlets below the coolant reservoir tank line connection are for cooling transmission oil. I just picked up a rad from an AT Loyale with those lines. Rad went into a 5spd, so I just left them along. You don't have to plug them, because the tranny oil runs through its own channels inside the rad. Just finish your install, fill, and test your hose connections. Luke

Not to be stupid, but could it have something to do with the Air Control Valve not opening when you are cold starting and also idling? If I have my ideas and concepts wrong, please correct me. Luke

Thanks guys for the advice and experience. I'll inflate it to 60psi, since the rubber appears to be in very good condition. I just don't want this thing blowing up in my face at the service station. But, now that several of you mention a full size wheel will fit under the hood, I'll add that to my shopping list for my next JY trip. Luke

Does anyone actually inflate the EA82 spare tire up to 60psi? I took mine off the car while doing some engine work, and checked the pressure, only about 33psi. But since it came stock with the car back in '87, I'm a little nervous about taking it to the service station and inflating it to 60. All that air inside that little tire!?!? What experiences do people have with this? Luke

I have read here that the 93 ignites at higher temperatures, thus preventing pinging. I think I've also seen elsewhere that the 93 doesn't release quite as much energy when it burns. In a NA engine, would these two factors combine to reduce gas mileage and engine efficiency? Thanks, Luke
