1982gl4 Posted April 11, 2012 Share Posted April 11, 2012 Great work, glad to see somebody stick with an EA. Keep at it! Quote Link to comment Share on other sites More sharing options...
O.C.D. Posted April 11, 2012 Share Posted April 11, 2012 In this last pic I see where the shifter rod enters the top of the case. I have an EA71 4-speed that leaks right here. Can you show me or explain what needs to be done to fix this leak? Are there seals on that rod and can you get to them from here? Quote Link to comment Share on other sites More sharing options...
Mechanical_misfit Posted April 11, 2012 Share Posted April 11, 2012 I can't wait to see how the 5 speed swap goes, I want to do the same with my wagon Quote Link to comment Share on other sites More sharing options...
wilcox Posted April 13, 2012 Share Posted April 13, 2012 im really curious to know how the hell you put the pistons, and pins on the connecting rods if your already installed the crank? im assuming its not like a convetional v-8 where you drop the rod/piston assybly through the cylnders.

Crazyeights Posted April 13, 2012 Share Posted April 13, 2012 You pull out the pins, install the rings on the pistons (after checking the end gaps) and using a ring compressor install the piston with the connecting rod at the bottom of it's travel. Carefully line up the eye in the small end of the rod with the pin hole in the piston and insert the pin through the access hole. Note don't forget to install the inside pin clip before you put the piston in or you can't get to it. Put the outer clip in through the access hole. Repeat 3 more times and your done.

wilcox Posted April 13, 2012 Share Posted April 13, 2012 wow! i went back and looked at the pics and there are definitely 4 holes to install those wrist pins. so then are there plugs that fill those holes? i noticed that one of the holes is cover by the oil pump Quote Link to comment Share on other sites More sharing options...

Can you show me or explain what needs to be done to fix this leak? Are there seals on that rod and can you get to them from here? There is a traditional pressed in seal there on this 5-speed. The 4-speed is the same Quote Link to comment Share on other sites More sharing options...

The rears do not have plugs, and remain open to the backside of the flywheel housing. Quote Link to comment Share on other sites More sharing options...
wilcox Posted April 13, 2012 Share Posted April 13, 2012 do they leave them open for oil return holes? Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 13, 2012 Author Share Posted April 13, 2012 There is just no reason to close them. Quote Link to comment Share on other sites More sharing options...
Crazyeights Posted April 13, 2012 Share Posted April 13, 2012 @wilcox One of the front plugs is covered by the water pump rather than the oil pump;) Quote Link to comment Share on other sites More sharing options...

tundrabrat Posted April 13, 2012 Share Posted April 13, 2012 Really enjoying the right up. The ej257 gets off my bench and put in the car this weekend and then I get to start putting my ea81 back together... can't wait. Quote Link to comment Share on other sites More sharing options...
wilcox Posted April 13, 2012 Share Posted April 13, 2012 this thread ALMOST makes me want to ditch me ea82 but not quite. Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 14, 2012 Author Share Posted April 14, 2012 You couldnt get me to touch a EA82 with a 10-foot pole I got SOME of my piston rings in today.... I think my hopes of reusing the old pistons is proving a bad idea.... Rockauto shipped me TWO sets... and backordered "indefinately" the other two.... :Flame: Priced out at a bit more than $50 shipped, Im temped to just return them and pick up an EBAY ITM set of EA82 SPFI pistons. I could do them for less than $150 shipped for 4. New pistons, rings, and pins. Comments?? Quote Link to comment Share on other sites More sharing options...
wilcox Posted April 14, 2012 Share Posted April 14, 2012 so do ea81 and ea82 have the same piston? Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 14, 2012 Author Share Posted April 14, 2012 Same bore, ea82 pistons are slightly taller from wrist pin to the top of the piston. This raises the compression ratio a bit. Quote Link to comment Share on other sites More sharing options...

wilcox Posted April 14, 2012 Share Posted April 14, 2012 wow, thats higher than i would expect in an older 4 banger. so do you have to worry about valve clearance in an ea81? Quote Link to comment Share on other sites More sharing options...
Idasho Posted April 14, 2012 Author Share Posted April 14, 2012 It is an interference motor, but its a pushrod motor, so assuming it is assembled correctly, there is zero chance of pistons hitting valves. Quote Link to comment Share on other sites More sharing options...
wilcox Posted April 14, 2012 Share Posted April 14, 2012 how thin of a head gasket can you run to try and get the cr up Quote Link to comment Share on other sites More sharing options...
