cam crank seal replacement questions

[bgambino]

It's been forever since I have worked on an EA82...I have a 93 loyale FI sedan.

I am doing a bunch of part replacements..t belt, pulleys, seals, WP, etc.

Does that small seal in the pic look like the crank seal??? That's what I ordered and thats what 1st subaru sent. Looks small but I have not taken it apart yet

 

Also...I read here something about o-rings being replaced (behind the cam seals maybe??). Can someone shed light on this as I want to get all the parts possible b4 starting

 

Also....I never did anything with the oil pump years ago on these (I didnt know any better and was a beginner). Do these need to be pulled for any reason like the EJ25 does for the screws/o-ring/new permatex?

 

this is a 1.8 with 40k original miles

(anyone got some extra carfaxes that could run a report for me--PM me if so...thanks)

 

thanks guys

yes, definitely replace the o-rings, they are typically very brittle by now. it's just an oring behind the cam cap - the part the seal slides into. just remove that cap and replace the oring behind - a couple 10mm bolts and that's it. call subaru....or search here i'm sure the part number has been posted before or maybe it can be found online?

 

thepartsbin.com has a cam seal set that includes both the seal and the oring, you can see it there, maybe it'll cross reference a part number?

 

pull the oil pump and reseal it. three parts:

oring/gasket - mickey mouse gasket

oil pump shaft seal

oil pump oring

 

no screws or anything like EJ stuff. remove the 12mm bolt holding the sprocket on the shaft before removing the timing belt - or use a 1" socket on the rear of the pump to hold the shaft in place to remove the bolt.

thanks gary

can you clarify this one point?

remove the 12mm bolt holding the sprocket on the shaft before removing the timing belt - or use a 1" socket on the rear of the pump to hold the shaft in place to remove the bolt.

are you talking about removing the bolt/s of the cam sprocket? and how can I hold something on the "rear" of the oil pump if it is still on the car (only the front is showing)

 

by shaft seal you mean the crank seal?

Any coments about the size of the crank seal they sent me/? its the size of my thumb...could that be correct?

I hate getting started on a job and then find i have wrong parts

 

as for the oil pump sealing

is the o-ring on the back like the EJ25? (I put ultra grey on the ej...do you do the same with this?)

is the pump sealed to the block with just untra gray(metal to metal)? where does the mickey mouse gasket come in?

 

thanks for clarification all!

[idosubaru]

you need to see a diagram, FSM, or picture. we have EA82 FSM's for free download over at subaruxt.com. but i'll try again. if you re-read my reply i think it's pretty clear. i mention three parts to reseal the oil pump and you're asking about whether i mean cam and crank stuff.

 

pull the oil pump and reseal it. three parts:

oring/gasket - mickey mouse gasket

oil pump shaft seal

oil pump oring

no

(I put ultra grey on the ej...do you do the same with this?)

no

is the pump sealed to the block with just untra gray(metal to metal)? !

no

is the o-ring on the back like the EJ25?

no

by shaft seal you mean the crank seal?

no. it says "oil pump shaft seal" ?

 

and how can I hold something on the "rear" of the oil pump if it is still on the car (only the front is showing)

with the oil pump removed, the rear of it is accessible. you remove the 12mm bolt with the timing belt on...OR...once the pump is off hold the rear of the oil pump while removign the 12mm bolt. sometimes it just slips in place so removing the 12mm won't work, it just jumps teeth on the timing belt.

 

any coments about the size of the crank seal they sent me/? its the size of my thumb...could that be correct?

size of your thumb does not sound like a crank shaft seal, sounds more like the oil pump shaft seal. on the EA82/ER27's the oil pump and crank seal are completely separate - oil pump is driven by the timing belt, not directly by the crank like on EJ stuff. maybe that's why you're confused?

 

 

where does the mickey mouse gasket come in?

it's between the oil pump and engine block.

 

you need to see a diagram/picture. you should be able to poke in any part number you have on various subaru sites, or call and ask them, or search here, and find out exactly what part you have and which you still need. some of the subaru vendor sites even have exploded diagrams don't they?

Look up "The Art of Subaru Maintenance" for a step by step engine seal and timingbelt procedure for an ea82 engine.

 

The smaller seal you have in the picture looks like the oil pump shaft seal.

Gary

thanks very much

 

please keep in mind that since you have a clear mental picture, your words seem to make total sense

When you tell me to put a socket on the back side...I would have understood better had you said to do so AFTER it was removed from the engine...bugt i appreciate your help

thanks Miles too...I appreciate the links

Guys, it's still not clear to me how one can hold the cam shaft from rotating after removing the oil pump. (This is to do with removal of the bolt that holds the cam sproket to the cam shaft)

 

Something about holding it from behind. Holding WHAT (cam shaft?) from behind?? (I assume from behind where the oil pump used to be?)

 

Can anyone shed some light on this?

 

Newbie here... (My timing belt job is coming up)
