October 25, 201510 yr The adjustments must be checked, most certainly if you swapped the rocker assys. Sometimes you have to just quit for the night. Start fresh tomorrow. Watch the Mentalist or throw in a Star Wars dvd. Heres a couple threads to read while you chill. http://www.ultimatesubaru.org/forum/topic/152312-ea81-rocker-arm-assy-left-and-right/ http://www.ultimatesubaru.org/forum/topic/155873-ea81-valve-adjustment-issues/
October 25, 201510 yr Author Would swapping the rocker arms back fix the issue without having to readjust? I really need to get this done tonight, and if that would fix the issue than that would be worth staying up a few more frustrating hours.
October 25, 201510 yr Im not thare so Im only giving an opinion. If they are reversed then theres a good chance swapping them back will get it to start. Ive never gone this deep withought adjusting the valves. Kinda a requirement for this job on the solid lifter motors. Too many variables like pushrods getting mixed up, head surfacing and new gasket thickness. They are always off after... I would take my advice in my previous thread, when you push too hard mistakes happen.
October 25, 201510 yr Author Okay thanks, I will try swapping them and if that fails then I will just have to figure it out later. You mentioned something about the push rods? Are the push rods different sizes? they all looked the same length to me.
October 25, 201510 yr The pushrods wear, possibly differently... Its miniamal but what youde be adjusting is a pretty tiny gap. Im assuming you have a solid lifter EA81, if so the adjustment procedure is annoying (in the car) but easy.
October 25, 201510 yr Author Thanks for your help/advice scout! I will try swapping the rocker assy and if that fails then I guess i will just figure it out later
October 25, 201510 yr Author Alright so I switched the rocker assy and it runs now but EXTREMELY rough. So I guess I need to adjust the valves. I found some info on a website about how to do it. Does this look like the proper procedure to you? 1)turn crankshaft until dist points at cylinder 1 (trace the plug wirefrom the passengers side --left as your facing it-- back to the dist.)2)make sure crankshaft pulley mark is lined up with center ofcrankcase (the seam where the two halves meet)3)pop off the valve cover4)intake: .010, exhaust: .014spin crankshaft CLOCKWISE 180 degrees. this is 1/2 turn, until themark on the opposite side of the pulley is lined up with the caseseam.now you adjust valves for cylinder 3, which is FRONT, passenger side.turn 180adjust #2 valves (drivers side, front)turn 180adjust #4 valves (drivers side, rear)
October 25, 201510 yr I tried to tell you this has to be done. It probably would have been easier than swapping the shafts back. Your supposed to loosen the adjusters befor you pull the rocker assy anyways. That procedure is correct, but I never use the marks to do it. It really dont matter what order you do them in either as long as the cyl being adjusted is at tdc. Once you start doing it and wrap your head around it youll figure it out.
October 25, 201510 yr Double check the spark plug wires. One of my first reseals, I had swapped a pair. It ran on 2 cylinders, but really bad.
November 3, 201510 yr Author UPDATE: Okay so I got my valves adjusted and it fired up after two cranks! Runs good except I think the electric choke on the stupid Hitachi is still messed up because the high idle wont engage when cold and once when it warms up it idles at about 1200-1300rpms (instead of 800-900). tried to burp the cooling system (got it on an incline, let it run up to temp with the cap off, heater on, also squeezed the upper and lower hoses multiple times to try to force any air out.) but I think there is still a bubble in the system because it seems to be getting a little warm still... of coarse I am still going by the dash gauge which is pretty inaccurate. Other than that, the ol' EA81 seems to be purring right along!
November 4, 201510 yr ... once when it warms up it idles at about 1200-1300rpms (instead of 800-900) ... Have you checked for Vacuum Leaks around the Carburetor and its Base? Any unhooked Vacuum line? Kind Regards.
November 4, 201510 yr As Jez said you could have easily left a hose off or a bolt loose and have a vac leak. You should also look at the throttle cable and check adjustment. Make sure the carb is returning to idle, and that neither butterflies are sticky.
