Replacing an oil pump on an EA81...

[skingry]

Some background: Picked up a '83 GL with ~343k miles, has a slight oil leak (probably less than a quart between changes). Doesn't burn oil, pressure washed the engine and engine bay, spotted a small leak between the pump and the block. Researched the forum and saw that this is common. In addition, it is common that the oil pumps are trashed on high mileage engines, so it's better to just put a new one in. Grabbed a NOS oil pump off of eBay for $40, it was mislabeled as a pump for a 1300cc engine... pics matched one for an EA81, so I bought it

 

Anyhow, getting to the point, do I need to use RTV or any type of sealant on the gasket when I install the new pump (High-Temp Permatex maybe)? I checked the Haynes and FSM, nothing in either of them say anything. Just thought I'd check with you guys, as you've probably done this 10,000 times between all of you.

Good question, do ea81's have the same mickey mouse gaskets?

No sealant is necessary. There's not mickey mouse gaskets thats the EA82 and ER27 engines.

 

I would remove the crank pulley to make it easier to see since you haven't done it before. Torque it to 47-54 lbs when you reinstall it.

 

The pumps are hard to remove sometimes. I leave the oil filter on and use it as a handle to wiggle the pump off the block.

Never pry outward when removing the oil pump. Wiggle it out in twisting motions, like extending a bicycle seat up.

you don't need to use any sealer on the oil pump when re-installing it, just the proper gasket.

 

this link is to a manual i found extremely useful when i was rebuilding my ea81. i think you may find it invaluable as well.
