Did my oil pump cover o-ring today + crank seal
I finished my replacement today, thanks to Zane for starting this thread and also everyone who contributed tips too.
My engine was leaking slowly but in a stream from the oil pump cover.
I was able to remove the 7 screws without incident, I had cleaned the heads with a small pick, simple green and q-tips.
I dont know if it helped any but I heated the screw heads with a 40watt weller soldering iron for a few seconds before tapping in the phillips bit with the hammer. I tried 5 different bits before finding one that was just snug enough to insert by hand with some effort. my oring was brittle and cracked in 3 pcs when I removed it.
By far the hairiest part was getting the o-ring to stay in the groove. I was getting frustrated trying to install it carefully while the other side would fall out, finally put a few dabs of vaseline in about 4 spots of the groove to hold to oring in place. I used a tiny bead of Toyota black FIPG along the outside perimeter of the cover. I wasnt sure I installed the cover without disturbing the oring so I let it dry overnight. pried out the old crank seal with a big flat screwdriver with the shaft wrapped in electrical tape, then hammered the new one flush using the old seal and a soft faced mallet.
Cleaned the crank pulley with 1000 grit sandpaper to smooth out the surface that the seal rides on, then finished with a rubbing of steel wool.
lubed the seal inner lip and crank pulley with 30wt oil then snugged down the crank bolt and started the engine, no more leaking from the oil pump cover.
opened the inspection cover and wedged a small prybar in the flywheel hole and tightened the crank bolt down. My torque wrench only goes up to 250 so I torqued to 250 then tightened about 10 degrees more for good measure.
My distributor o-ring is next.
I found it easier to get the 2 main engine belts off and on by removing the fan clutch and removing the fan pulley off the waterpump, much easier getting the belts on too, put the belts on the crank pulley, alternator then slide the fan pulley into the belts then onto the 4 studs.
