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

I'm trying to learn the 'plumbing' on the EA82, and keep running across references to the Air Injection System. Correct me if I'm wrong, but I gather that the EFI EA82 does NOT use air injection? Thanks, Luke

I've never heard of molded hose before. Is that something available from auto parts stores, or do I have to get it from the dealer? Any info appreciated, thanks, Luke

As a result of cutting the old radiator hose off when I pulled it at the JY, I now have a situation where a replacement radiator hose is turning too sharply and kinking, or "flattening" as a result. The hose is definitely the proper length and diameter, it's just going through too sharp a turn to hold its shape. What is the solution to getting the hose to stay fully expanded and not restrict flow by collapsing at the bend? This particular hose has one of those "spring" things at one end, which is helping, but where can I get another "spring" for the other end? Thanks, Luke

snotrocket, sure wish i could be there to watch (help) with your re-install of the ea82. i've never done anything that complex before, and i'm frankly scared of all the wiring and especially vacuum hoses involved in disassembly and reassembly. i get the idea of how an engine works, but the entire chilton chapter on emissions control was lost on me. any tips to help make this stuff a little less mystifying? thanks for the 'for sale' tip, i'll post my WTB over there.

hello i'm new around here. i started lurking the other day as i'm in the process of replacing the radiator and fan from an '87 dl 5spd sedan. i'm glad i found this thread about the radiator drain plug. what i'm getting is that drain plugs are: a) universal, in the sense that there are many sizes available, but you have to match up the size and threads something found at NAPA, or the junkyard if you want to go hunting. i'm also thankful for the thermostat thread, and finding out that you can remove the "mud-panel" from the bottom of the car, since the drain plug is in pretty tight and it's difficult to access it from the top side of the car. i suppose i would have learned all this eventually on my own, but it's a lot nicer (and WARMER too!), to have read that what I'd thought would work, will work. also I am looking for a replacement radiator fan for an ea82. the one on the passenger side. anyone have one? thanks
