January 23, 200620 yr Anybody give me a quick run down. im pretty sure i need to dot his now since o got my head gasket changed the valves wont shut up.
January 24, 200620 yr Well, I ... Pull radiator Pull V belt Put valve marks on center. (Three lines on the flywheel...not the degree mark.) Take Crank pulley off Remove timing covers One mark on the pulley should be pointing up and the other one down(You've done a head job, you know this already) Take timing belts off Take oil sending unit wire off Remove the bolts holding oil pump and remove pump. I used a crescent wrench and put it on the impeller and then took the cog gear off the oil pump with a socket wrench. Then the shaft should slide out...clean and then inspect the shaft, impeller and gear...and the respective mating surfaces. If it all looks good, replace gaskets, if it is scarred get a new/rebuilt pump. Clean everything up. Some people recommend putting a little bit of gasket sealer on the seam of the engine, where the pump mates to it (at the 12 and 6 o' clock posistions). You impeller gear should have a "B" or some mark on it, on the side that goes into the engine...your driven gear will have one too. Put the B side on the inside of the engine. And then installation is reverse of removal. Make sure the mickey mouse gasket doesn't slip out when you put it on. BUT when you get the pump bolted on completely, spin the cog gear by hand and make sure it spins freely with NO resistance. I hope this helped. Justin Johnson
January 24, 200620 yr pretty straight forward, like he said. remove crank pulley, timing belts and necessary covers. remove oil pump. great tip on the XT6 - use a 32mm socket on the oil pump impellor, perfect fit to loosen the nut on the face of the oil pump and replace the seal. the XT oil pump is a little different, so i'm not sure if the impeller is the same size, been awhile since i've done one of those. but my guess is there's a socke that will work if it is different. use a dab of anaerobic sealant at noon and 6 oclock on the oil pump housing to help seal where the two halves of the block come together behind the oil pump. install gaskets/seals and you're done. if i recall right, the FSM isn't very clear on the torque specs for the oil pump. here's a link to the oil pump write-up i did for the XT6. EA82 is a tad different, but this may help if you run into any issues: http://www.xt6.net/forum/viewtopic.php?t=5243
