1992 loyale radiator hoses
GeneralDisorder replied to Centerline6's topic in Old Gen.: 80's GL/DL/XT/Loyales...
It's likely the thermo-switch that turns on the fan. So yeah it's pretty important. GD -
Frankenmotor question. Searched.
GeneralDisorder replied to xbeerd's topic in NA Fuel Injection Engine Tech
Can't use em. The pistons will hit the HEAD and you will cause severe and irreparable damage . They crest above the deck of the block. What you have are the 251 gaskets. You need 25D gaskets or Cometic's. As I have said the pistons are NOT any shorter on the 99. They are the same piston as 97/98. They crest above the block and are dished with a squarish pattern in the center. The raised portion around the dish is just exactly as high as the '96 pistons. The gasket thickness is to prevent piston/head chamber interference. And yeah - Fel-Pro or any aftermarket non-performance head gasket with the 25D block is a super bad idea. It will not end well.

Auto tranny cooler. Just pull off the hoses and leave the nipples open. GD -
sube101 and I worked closely on the design of dual-to-single adapters which he can produce for anyone here at a cost of about $80. You simply cut off the dual port sections right after they merge together and either weld or clamp the adapters to the remaining "stubs". They work very well and are easy to install. A hack saw or die grinder is all that's needed and you can use generic exhaust clamps from the parts store if you don't want to do any welding. GD

No it's the same stroke. Different piston height. And yes they crest above the block. But the 25D pistons are dished like a turbo piston in the center to lower the compression. 251's don't crest above the block but they have flat-top pistons AND use a much thinner HG resulting in higher CR. You can always get a Cometic gasket to lower it back down some. The '96 25D has flat-top pistons AND they crest above the block so even with a thick HG (required) they are still over 12:1. GD -
Weber carb refusal to idle?
GeneralDisorder replied to 92_rugby_subie's topic in Old Gen.: 80's GL/DL/XT/Loyales...
There's no ECU in those cars. There's a fuel pump control unit that runs the fuel pump for 1.5 second when the key is turned to run and then waits for a tach signal before turning on the pump again. They don't fail often - unless they get wet and corrode inside. I suspect you really need to clean out the carb - probably something floating around in the bowl and intermittently clogging a jet. GD -
Order the hose from the dealer - it's only about $12. Nothing beats new, supple rubber. GD

Mechanic Recommendation?
GeneralDisorder replied to Hooligan's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Heh. Thanks for the kind words from all my USMB friends! :-p By all means you are welcome to bring it by my shop. I'll give you some pointers on getting your fuel mileage up and finding the source of what ails your Loyale. Give me (Rick) a call - 503-880-4084. GD -
Frankenmotor question. Searched.
GeneralDisorder replied to xbeerd's topic in NA Fuel Injection Engine Tech
99 block will be an 8 bolt bell-housing. It's the only 8 bolt dual cam N/A out there.... Well till you get into the H6's and newer FB/FA engines, etc. It's really a 251 case/crank/rods with 25D pistons. A little trick on Subaru's part. GD -
Cast iron hubs would be a DISASTER waiting to happen. Too brittle. They are high tensile steel and welding them with standard .035 MIG wire has not been a problem for filling the holes. I fill the holes, grind the welds down a bit then turn off the last bit of excess in my lathe. For the studs I just fusion weld the edges of the stud to the hub with TIG. This works very well and when you need to replace a stud it's not that difficult to grind through and pop them loose. GD

GeneralDisorder replied to xbeerd's topic in NA Fuel Injection Engine Tech
Yeah it does. It was an experiment. Now it's going to need E85 and a standalone to take advantage of the crazy high compression. GD -

GeneralDisorder replied to xbeerd's topic in NA Fuel Injection Engine Tech
All 2.5 bottom ends when coupled with 2.2 heads are interference. The 96 is MORE interference due to its flat top pistons. It's also a very bad candidate for a FM - the compression is over 12:1 and the ECU will totally freak out. The best FM is made with the '99 25D. Comp. ratio is 10.6:1 and they have 52mm rods. 97/98 are same comp. and 251/253 bottoms will yield about 11.5:1 GD -
Weber carb refusal to idle?
GeneralDisorder replied to 92_rugby_subie's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Might not be the pump. Check for power to the pump while cranking, check for fuel flow out the fuel line at the carb, check fuel filter, etc. Don't troubleshoot with Visa - you should have learned that in my shop. GD -
EA82 head crack between valves
GeneralDisorder replied to spayordie's topic in Old Gen.: 80's GL/DL/XT/Loyales...
My experience has been that the crack will just come back even if you peen them, stitch them, etc. Since it's a non issue I go with Subaru's engineering advice - ignore them completely. Never had a failure related to between-valve cracks on a non-turbo. GD -
It's just not an issue in the real world. I'm sure they are pretty but your fears are unfounded. There's a Brat in my garage that ran three rally-x seasons on poorly drilled and badly welded (not my work) 6 lug hubs - last season it was AWD and is sporting a high comp. 2.5 pushing about 180 HP. Not a single failure ever occurred. The whole design is overbuilt and cracked hubs just don't happen. Also - when I do them I just weld the stud in place. That pretty much makes the seating against the back of the hub a non-issue. I've done it without before but over time they will work loose and spin since the splines were not broached but just formed from pressing in the studs. GD
