Factory EA82 Fog Lamp Installation Instructions
DaveT replied to carfreak85's topic in Old Gen.: 80's GL/DL/XT/Loyales...
Wire the relay to a switch on the dash. Feed that switch from one of the power lines that is switched off when the ignition is off, like the radio feed. Hot power to relay for the lights, run a new fused wire from the+ battery terminal. -
87 BRAT with mysterious wobble
DaveT replied to HRBrat's topic in Old Gen.: 80's GL/DL/XT/Loyales...
I meant wiggling - left right constantly, or fading in and out. I've had 2 causes of this. 1 is out of balance tire / slightly bent rim. Other was tread bubbled off the steel belts in the tire. This turned out to be caused by the alignment being too far off spec. Jack up a wheel, slowly turn it while watching the tread surface. Obviously, it should be steady, not changing. -

Does the steering wheel wiggle varying with rolling speed? -
Bubbling in coolant reservoir
DaveT replied to MTNjohnny's topic in Old Gen.: 80's GL/DL/XT/Loyales...
The cracks are cosmetic. They don't go far enough to intersect a coolant passage. No effect on driving or running. Other cracks that cause leaks and problems can happen with severely overheated heads. -
The re enforced o rings go in the cam tower to head joint. The head gaskets have a copper seal. This if for the oil channel to the cam towers.
-
I don't know that brand / kit. The OEM intake gaskets are some kind of very firm slippery stuff. Do not use or trust cardboard like gaskets there, I have had them fail and damage headgaskets more than once. It was a few years ago, I bought several sets of intake and orings from a dealer. It's worth a try for the reliability. The metal reinforced orings, I'll go searching industrial parts suppliers before I use plain orings, if the dealers don't have them.

The one I read was specifically EA82 non turbo. I don't know if there were any for the others. -
Dealer-installed EA82 Cruise Control Instructions?
DaveT replied to carfreak85's topic in Old Gen.: 80's GL/DL/XT/Loyales...
The only thing I have is what is in the factory service manual. Not sure if there is anything about dealer installed. I'll have to look.... -
While you are getting gaskets, you want OEM intake gaskets, and the OEM re enforced o rings for the cam towers.

Bubbling in coolant reservoir
DaveT replied to MTNjohnny's topic in Old Gen.: 80's GL/DL/XT/Loyales...
A small crack between the intake and exhaust valves is normal. Nearly all of them have it. All of mine have it. There was a service bullitin about it years ago. -
The over normal temp is a sign of air in the cooling system. Every time that happens, it worsens the damage to the headgaskets. It usually slowly progresses. You might get another week, or a few months. If you check the water level before every drive. The radiator must be 100% full, and the bottle at the full mark. You need to evaluate the rare of loss. As it increases, the time you can get away with running it grows shorter. Also, this only applies to relatively short runs, 30 minured or less. Longer gives more.time to push more coolant out, causing more over normal temp, faster degredation of the headgaskets.

El Freddo covered the options. IF you check the coolant in the radiator and the tank before every drive, and top them off, you might get to drive it [short drives only.. 15-30 minutes.] for another few days to another few months. It will get worse, until it completely blows the head gaskets. -
I got a pump un stuck. Didn't take as much as I thought it might, but this could vary depending on how crummy the fuel was, etc... 10,000uF charged to 15V connected to the pump with less than 2 feet of total wire. [Low resistance is part of how to get a big impulse of energy in a short time] This pump didn't run when I had tested it with straight 12V a year or so ago. Using the capacitor, I could have gone to 24, 36, or even higher. The shortness of the pulse would limit the heat to avoid burning out a winding, But the short burst of higher voltage would give it a bigger kick of torque momentarily.
-
The stock pumps get stuck if they are allowed to be dry. Don't have enough tourque to self free. There is no way to get at the moving parts without cutting the case open. I just had a thought. .... I'll have to try on one tomorrow. ... hit it with a pulse of higher voltage from a capacitor. There is a chance that might work.

New guy looking at getting a 79 brat
DaveT replied to Rayrook's topic in Old Gen.: 80's GL/DL/XT/Loyales...
#1 thing to keep old Subarus running without major repairs is keeping the cooling system in top condition. All of the cooling system hoses, not just the radiator and heater hoses. The radiator in good condition. Checking the coolant level in the radiator and the recovery tank frequently. All of the parts are getting harder to find. So you have to seach, scroung, collect. Mechanics who know these old ones and thier quirks well are rare. So you have to DIY or pay big. Not a great choice for a daily driver unless you have another vehicle for backup when it takes a week to find a part. -
1987 gl wagon headlight issues
DaveT replied to cornbreadfed's topic in Old Gen.: 80's GL/DL/XT/Loyales...
That makes it sound a bit more like something dirty / corroded in the switch, or the wires and connector right near it. -
The intermittent click no crank is almost always a high resistance connection in the wiring to the starter solenoid. Easiest fix is to add a relay. One other possible cause is that one of the contacts in the starter solenoid has eroded down to where it barely touches when the solenoid pulls in.
-
Your belts are too loose, but that won't cause the running problems. Loose belts are at more risk to skip timing. I do is correct, read and follow the FSM procedure for setting the tension. I add the step of a 5 second run and then reset tension. The belts inevitably move to the location they want to run, and end up loose. You have to connect the green test connectors before setting or checking the timing. If you don't, the ECU will be adjusting the timing and you don't end up with the proper position / angle.

Possibly a loose connection. burned contact. failing relay. Not a common problem, from my experience since 1988, or what I have seen on this forum. -
As far as I remember, it just wires in. Power, maybe a signal to the fuel pump shutdown? It still has electronic points. No ECU.
-
SPFI distributor does not have vacuum advance, so the timing will be fixed. SPFI needs 21PSI fuel pressure, or it will be very unhappy. The CTS main function is to tell the ECU the engine temp so it can act as the choke / fast idle. The ECU will need the MAF and the TPS to function in anything like normal mode.

I am not 100% what year this change happened, but somewhere between 86 and 90, they changed the final ratio in the 3AT. Just a little. My 86 ran at 3600 3700 at 65, my loyales ran at 4000rpm at 65. Makes a big difference, as did the spfi vs Hitachi carb. The ECU running ad you describe is most ikely operating in limp mode, which is less than ideal. When they first switched to the SPFI I worried about the reliability. ... 30 years later I am still running the same parts. Collect some spares..
-
I had a carbed 86 4wd 3at. It takes a while to get to 65. 4000rpm at 65 is normal. Steeper hills would need close to full throttle. This is with stock tire size. Running bigger diameter tires is like a higher top gear, so slow everything down, especially with the marginal power from a Hitachi carb. Iirc, the SPFI makes a little more than 10 more HP.
