Hey Everyone. Just did a coolant flush, new thermostat and radiator cap. With the coolant back under pressure my top radiator hose burst and coolant went everywhere. Didn't think much of it. Replaced the hose and no more leaks. But after this, the car developed a significant hesitation under load (accelerating at traffic lights). Pulled the plugs and one of the plugs was covered in coolant (where the radiator hose burst). I had resigned myself to thinking it was a blown head gasket, but I installed a new spark plug and the problem has gone away (for now). I have done a chemical test on the coolant for exhaust gases which was negative. Car is not overheating. No coolant in oil. Is there any way coolant could have got into that cylinder because of the leak from the burst hose or am I kidding myself and it's probably a head gasket? '91 Legacy EJ22 Cheers!

Hi All. I have just been flushing the heater core in my EJ22 and I cannot remember which hose goes to which connection at the engine. There are two steel hoses coming out of the engine (a top one and a bottom one separated by about 2 inches) which one goes to the heater core and which one is the return? Cheers guys.

Hi Everyone. I am replacing the ignition relay on my 91 Legacy (the brown six pin Jideco relay). I am pretty confident I have found where the relay is but I am having heaps of trouble getting it out to replace it. Does anyone have a step by step process to complete this task as I cannot seem to get enough access to the area or an understanding of how it is actually fixed up there. Thanks in advance. Ryan.

Sorry, yes MMO through the crank case. Sea foam through the intake. You can also try some BG44K in the fuel system. Unfortunately with the high mileage it can be very hard to clear. I know this sounds silly but you can avoid the problem by just taking your time up the hill. Don't put it under so much load and just go slow. Everytime you do this to replicate the issue it has the potential to make the valves worse. As far as a valve job on my ej22 it means pulling the engine (it can be done in situ but for someone more skilled than me) I am not sure about the 96 but I imagine it will be the same.

Seems to be a very common problem. I had the same problem with my 91 Legacy. From the studies and fault finding I did it is caused by carbon build up and sticky valves which cause a loss of compression under load. I would recommend using Marvel Mystery Oil. Put some sea foam through the intake. Short of doing a valve job you need to try to free the sticky valves and remove the carbon build up. The issue will only occur on a long hill under load. If you pull over it will shudder and shake on 3 cylinders and then it will clear itself. Some people have also had some luck replacing the ignition relay.
