The garage queen gets a new heart ::ea81 build::

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?

im really curious to know how the hell you put the pistons, and pins on the connecting rods if your already installed the crank? :confused:

 

im assuming its not like a convetional v-8 where you drop the rod/piston assybly through the cylnders.

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.

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

There is a traditional pressed in seal there on this 5-speed.

 

The 4-speed is the same :)

Yes, two plugs for the front of the motor.

 

The rears do not have plugs, and remain open to the backside of the flywheel housing.

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.

You couldnt get me to touch a EA82 with a 10-foot pole :popcorn:

 

 

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::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??

Same bore, ea82 pistons are slightly taller from wrist pin to the top of the piston. This raises the compression ratio a bit.:drunk:

wow, thats higher than i would expect in an older 4 banger. so do you have to worry about valve clearance in an ea81?

It is an interference motor, but its a pushrod motor, so assuming it is assembled correctly, there is zero chance of pistons hitting valves.
