I just purchased my first Subaru - a lovely project car with an '86 EA82T Engine.
The previous owner had experienced a timing belt failure and had replaced the water pump, thermostat, timing belts, plugs and wires, and 'some hoses' (radiator) and once it was back together, it had no power and would overheat quickly.
That's when he decided his head gasket was blown and sold it to me.
Well it "runs" - after a fasion. It will run rough, stumble, backfire, and die within a few seconds of being cranked over unless you give it about half throttle, which will jump you to 3000 RPM where it runs... kind of smoother. Sorta.
From what I can hear my driver's side bank is running great, my passenger side is not. I'm headed back out to verify this by pulling the plugs out of one half of my engine, and then the other.
I don't think I have head gasket trouble. All cylinders are within a few pounds of 100 psi. This got me thinking valves and ignition timing
I've rechecked the timing, rechecked the distributor, even pulled the valve cover off the passenger side so I could see the cam timing for myself.
I am confident that I'm not a tooth off on either cam sprocket, and have verified that my distributor is pointing at the point for cylinder one when cylinder one is reaching TDC.
Where should I go from here?
I'm new to these engines, is there anything the P.O. could have done during the service he performed that would make it run like this?
Having checked compression and valve timing - it is probably spark or fuel... right?
Thanks for your help Subie friends.
