Yes, induction is but one possibility. The good thing about Gloyal's finding, is that it's repeatable and something people can try...all over the world. It's also quite likely that it happens. I'm pretty sure a lot of people never consider it. It's the reason late model Subaru's are picky about plug wires. Subaru calls it "misfire". One and Three are next to each other in the block. 2 & 4. Fire one after the other, the plug wires run close together. Think of the poor old EA-82T:) Lots of boost, bad cooling system. #3 is where the gasket and head crack problems start, by the turbo (heat), induction by #1. Same thing with #2 induction to #4. I have another 140K EA-82T I'll be looking at this summer. "This is really a giant problem when the two wires happen to be consecutive in the firing order! In other words, the current flowing to one cylinder can induce a secondary voltage strong enough to prematurely ignite the next cylinder in the firing order." "This is one of the worst forms of detonation." And I agree. Doug Higher compression ratios...It's more likely to show up. It can and does happen in distributor caps...why they got larger over the years. Crossfire happens too. In a small block Chevy, number five and seven are consecutive in the firing order, and next to each other in the block. People chased "induction irregularities" and "lean in #7" until it was sorted out.

"I don't know why......but I've gotten cars with this same case.....over and over......and the misfire codes ALWAYS go away with good shielded wires, some extra tape around the injector pigtail, and seperating the two." Bump. Edit:"When electrical energy is flowing through a conductor it will tend_because of a property called inductance_to create an electrical impulse in any other conductor that happens to be close by. This phenomenon is used in the ignition coil_which is a step-up transformer_ to create the high secondary energy that is delivered to the spark plugs." "The same thing can happen in spark plug wires that are very close to each other. As the elecrrical pulse moves down one wire, it can induce a secondary_though considerably smaller_pulse in the second wire."

EA 63 engine rebuild question
Quidam replied to Adam Bahm's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Hey, Look here for gasket sets, rings, valves...bearings are common among early ea engines I believe. http://stores.ebay.com/Vintage-Imports-Inc_Subaru_W0QQ_fsubZ9742663QQ_sidZ7898167QQ_stickyZ1QQ_trksidZp4634Q2ec0Q2em14?_sop=10&_sc=1 Have a couple more sources if you need them. The FUJI exhaust valves on that page for two dollars each are original equipment. Doug -

EJ to EJ, the spec is "FLAT". I'm not sure what would be best EJ to EA. -
mazda rotery engine transplant, is it possable?
Quidam replied to hotrod_sol's topic in Subaru Transplants
http://athensohio.craigslist.org/cto/1583731605.html I don't see many of these around here. Are those rotarys disposable? I mean, they're not remanufactured. Doug -
EA Flywheel Weight Loss Diet?
Quidam replied to Txakura's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Flywheel spec for XT6 is .815, for an EA-82 .827. But it's the same clutch kit. From the disc surface to the pressure plate mounting surface. What do you think of that? Doug I got those specs from RHINO -
Subaru wheel choices? possible new development!
Quidam replied to blownchevelle503's topic in Subaru Retrofitting
there are some heavy 'farm wagon' quads that haul trailers and such, but who know's if they'll work." Look at these:http://www.summitracing.com/search/Department/Wheels-Tires/Section/Wheels/Part-Type/Wheels/Brand/Summit-Racing/Wheel-Bolt-Pattern/4-x-137mm/Load-Rating-lbs/1-124-lbs/Wheel-Diameter/14-in/?Ns=Rank%7cAsc 14", (I've been told to check back for 15"). 4X137 bolt pattern, 1124 lb. load rating.

FYI. A simple dry compression test will tell you how good the rings and bore are on any engine. That one should be around 168 if the bore and rings were like new. Doug

mazda rotery engine transplant, is it possable?
Quidam replied to hotrod_sol's topic in Subaru Transplants
"But rotarys are oil burners and pigs when it comes to fuel" You can have carb or EFI. The RX 4, 13B 1308 cc came with a 465 cfm spread bore Hitachi 4 Bore Carb. If I have that right, and I'm not sure I do. That's a big carb. -
unusual head gasket failure, EA82
Quidam replied to MilesFox's topic in Old Gen.: 80's GL/DL/XT/Loyales...
"1. what possible scenarios could have caused this type of failure" Possibly the different thermal expansion rates of the heads and headbolts? I know people who "say" it didn't really get that hot, but they still get home with them:) Doug -
Hey, Product Core Unit Price Qty Item Total For your 1994 Subaru Justy 1.2L MFI SOHC 3cyl Felpro/Conversion Gasket Set Part Number: CS9528 Availability: Ships within 3-5 business days. N/A $38.99 1 $38.99 Timken/Camshaft Seal Part Number: 223018 Availability: Ships within 2 business days. N/A $6.99 1 $6.99 SUBTOTAL: $45.98 SHIPPING: $5.70 TAXES: $3.48 TOTAL: $55.16 These will be charged when shipped, for an EF-12. Btw, I have OEM crank seals too. IME, there can be like 3/16" differences on where the sealing lips of the seal rest on the crank for instance. So it may seal like new, just depends. Other option is redi-sleeve, the Subaru doesn't have to leak oil. I have a National cam seal kit for the EA-82, USA. Same deal with the lips, as I have two brands of seals. The Timken Redi-Sleeve is about $20.00 compared to the Federal Mogul. National is the MFG, looks like FM is the middle man here. Costs more. AutoZone saved me money on the conversion gasket set and I still prefer that parts be delivered. Doug

Are JDM S/R Turbo trannies 23 spline outshafts?
Quidam replied to moosens's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I don't know. But JDM...I got a power steering pump an a water choke on one EF-12, before I knew they existed. Doug -
http://www.northernautoparts.com/ECatalog.cfm?RequestType=GetCategories&VehicleId=1268614&EngineName=1.8L H4 GAS FI VIN 4 The Beck/Arnley stuff is drying up, the old stock anyway. I bought two sets of their piston rings and they are up-scale...I don't know who makes them. USA The oil scraper is a Napier ring, costs more to produce, less friction. They're better than OEM. They fit better. I had read about Melling making the balance shaft chain for the EF-12. I ended up at Northern Auto Parts. They sell them, like $16.00, they sell a guide too that you can't find just anywhere. They have a balance shaft sprocket, not usual. It's ITM...only ITM I've bought is FUJI. What I found too were those Victor gaskets:) For the EF-12, and I just looked, for the EA-82. They have the Victor exhaust manifold kits. My choices now have evolved, dealer, Rock Producs, Fel-Pro, ITM, Victor, Cloyes, Melling...and of course, the ebay stuff.

Oh, and btw: You've stated your qualifications here before so now is as good a time as any for me to state mine. 1504 hour, 2 year program Auto Mechanics. Year one I scored the highest in my class on a state acheivement test. 2nd year, I scored the second highest. That was the factor in a new car dealership recruiting me. That got me "stripes for skills" when I enlisted in the US Army as a 63 B wheeled vehicle mechanic. E-4 within the first year. Doug

I did a quick google: Subaru introduced the Subaru Legacy Sport Sedan to the US domestic market for the 1991 model year. The Sport Sedan was a 2.2L 4-cylinder, SOHC, turbocharged, non-intercooled variant of the JDM Legacy (which was fitted with a 2.0L 4-cylinder, DOHC, turbocharged and intercooled engine to compete in the World Rally Championship). The USDM engine produced 160hp @ 5600rpm, and 181lb/ft of torque @ 2800rpm. Pretty modest numbers for a turbocharged car. This is due to the lack of an intercooler and factory-limited boost at 8.7psi (http://www.xmission.com/~dac/library/turbo_info.htm). ENGINE BLOCK (information and pictures adapted from: http://www.sdsefi.com/air17.html). The engine has a closed deck providing a much stiffer cylinder assembly and better head gasket sealing. Cast iron liners about .125 thick are cast right into the aluminum. The block is a precision medium-pressure sand-cast unit, which affords the block the necessary rigidity to withstand closed decking (SAE technical document #890471). The majority of Subaru blocks are instead high-pressure, die-cast aluminum, and although stout, do not have the same rigidity to withstand high boost pressure. This is due to high-pressure casting forcing air pockets into the aluminum mass as it cools. The result is a block with more localized stress areas within its structure. Conversely, a medium-pressure cast aluminum crankcase will be denser and more rigid. Subaru spared no expense in the development and manufacture of the block as the medium-pressure casting procedure is quite extensive, and more importantly, expensive, when compared to the typical high-pressure castings (xephyr). It should be noted that the increased density of the M-P aluminum block has the propensity to retain heat to a greater degree than its H-P brethren. Subaru has addressed this issue by incorporating plenty of coolant passages in the head to block area and a wide bore spacing, which allows for higher boost levels to be maintained. The coolant flow path has split passages in the block to force coolant from the lower block, through the head and back into the upper block. This setup uses natural convection to aid direction and efficiency of coolant flow. Closed Deck Block Oil Jets/Main Center Bearings Engine Block Half The turbo engine has piston oil jets to cool the piston domes under boost. In order to feed these jets (and the turbo) Subaru utilized a higher pressure, larger flow oil pump (xephyr). Extensive ribbing in the casting on many of the water and oil passages help to dissipate heat from these areas as well. The block halves are attached with ten 10mm bolts and seven 8mm bolts, creating a very rigid design. The 3 center main caps which span the cylinder bores are 2 inches thick and carefully radiused to preclude any chance of cracking.

Ill buy the winner a beer....if your in CO.
Quidam replied to bigo1966's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Allright, I'll go ahead and type it:) It's because you have the tach wire hooked to the blower motor. I'll be out there in a couple of months for the beer. Doug -
Hi, I've bought from importers on the west coast, so that's all I'm familiar with. Last one I bought from an individual who bought, then didn't use it. Ended up with shipping to me, about $70.00 less than he paid for it. Doug

One thing you can do is ask the seller to pop the valve covers off and take a picture for you. If they won't do it, I wouldn't buy it. A coating of sludge would be a no go. If it's clean with a little varnish, it's probably ok. Doug
