so i have a 93 loyale with 150k on the ticker... had TOD when i bought it at 144k so i replaced oil pump seals went away for a few thousand and came back. replaced the oil pump with one from the junk yard that i found within spec. upon start up after instal the noisy is no longer a tick but a clack now and coming from the drivers side mostly i think. i put sea foam, mmo, rislone, everything with no help. could i have a bad hla or what? i really dont wanna damage my engine and ive read all the threads here regarding TOD but i have oil pressure, no leaks, replaced front main seal, etc.... please help me save my ea82 

Mine clattered away now and then  from 150K km (90K miles) shortly after buying it,  was alarmed also was told not to worry about them so I didn't. 

Had car for 14 years with no issues apart from replacing clutch and rekitting carb.

.

What weight / viscosity of oil do you use.   Lifters can be sensitive to oil viscosity.

 

Try 15W/40 (recommended)  or a lighter 10W/30 recommended for EJ motors

I kindly suggest you to run it for a while with a quart of oil substituted with ATF, then flush and use 20W~50 oil; the ATF has more detergents, which will do a cleanup on the tiny oil passages on the Hydraulic lifters; also 20W~50 works better on EA82's in warm climate.

 

Kind Regards.

I'm currently using 10w30 with seafoam in it... I'll try the arc tomorrow and up to a 15w40 or 20w50

Does it matter which ATF I use? Is there a kind with more or less cleaning agents, etc

dextron 4  will work well ,  when you resealed the oil pump did you replace the shaft seal as well . ?

Good oil changes are key.

 

Every single TOD i've encountered was repaired with a new oil pump. The pumps don't show wear or issues so I'm not sure what "causes" it, I just know that new pumps solve the issue most of the time.

TOD is so common and oil pumps so often the cause that i wouldnt' consider one used one determinate. it could still be the pump.

 

The only ones I've seen that were something else were due to prior engine issues compromising the HLA's - they're stuck or seized.

1. was the car previously overheated?

2. has it seen excessive use - offroad, towing, really long oil changes, run low on oil?

3. is it a 300,000 mile engine? you say it's 150k so looks like it's not unless that's vehicle mileage and the engine has more?

 

A problematic HLA should be a bit more obvious because the TOD is limited to one cylinder/area. Stethoscope may help

 

You can replace offending HLA's - it's been a long time since they've all rusted away around here but i've seen them stuck badly enough that they don't compress in a C clamp. pull the valve cover on the offending side and rotate the engine by hand to see if one of the HLA's is notably different than the rest - too much clearance or not moving at all or collapsed - it doesn't pump up. If it's stuck mid-stroke it might be hard to tell insitu.

 

*maybe youll get lucky and be able to find a bad one just by pulling the valve cover.

Oil pump shaft seal. 10w 30 is too thin unless you are in very cold climate. +1 try the atf trick.

UPDATE.... So I drained the 10w30 and seafoam... Replaced with a quart of ATF and 20w50.... Lifter noise is quieter.. But NOW I GET RANDOM LOW oil pressure light at idle.... Every subaru dealer I've called says oil pump not available anymore.... PLEASE HELP. where can I get an oil pump??

ebay has new ones listed.

The Oil / ATF mixture only have few hours working in your car, they do not work magically fast... let 'em do their job for a while. The new oil pump is available online, in example:

The one on the Link above, belongs to an EA81, this is for the EA82 engine:

Thanks for all your help guys... Is there no where to get locally in the Portland metro area?

This is the noisy my loyale makes.... Any ideas?

cant seem to attach the file!!!

This is what my original owners manual says...

It does seem to come and go does it all year round... for the past 9yrs

If ya want an oil pump I recently went out to pick n pull off se foster there is a 94 loyale wagon

Oil pump shaft seal. Possibly one of the o rings that seal it to the block? If the tick is caused by the pump, it's due to air getting in through the old seal. It takes a long time for the air to get out of the lifters. It takes a long time for the atf trick to clean stuff, too.

 

I haven't run 20w 50 in an ea82. Too cold here half the year, and the timing belt doesn't need extra load.

 

Typically thicker oil raises pressure on the gauge, I don't know what effect it may have on the lifters.

 

If it's only one that is noisy, it may be stuck or failed, and just need replacing.

 

Oil pressure drops to near zero at idle normally. There is no load on the engine, so not too big of a deal. The gauge on the dash is not super accurate. To be sure you have to get a mechanical gauge.

... I don't know what effect it may have on the lifters ...

 

Helps to keep 'em Quiter, somehow.

 

I believe that the thicker oil cushion between moving metal parts also helps to elongate the internals' lifespan.

another update... so after about a week of having trans fluid in my oil, with 20w50... the tick is gone but the clack remains... odd thing is it only does it after the car warms up... upon start up in the morning its non existent, but as it warms up it comes to life and clacks away, also it is intermittent under power, sometimes loud, sometimes quiet and varies with throttle pressure.... what gives?

Can't be sure regarding the Clack sound... But seems like you've run the ATF + Oil mixture on your EA82 engine, for enough time & mileage, especially since you stated that the T.O.D. has Gone; so I kindly suggest you to drain such mixture, change the oil filter, and try with fresh oil; I use Valvoline's "MaxLife" 20W~50 for high mileage engines with great results...

 

However, if the Clacking sound is severe, I suggest to try to Diagnose it / repair if necessary, prior to change your Oil.

 

Kind Regards.

It's not severe... Like I said it is intermittent, and doesn't do it when cold and seems to be affected by throttle input... I was just outside while on break at work showing a co worker and also noticed my timing belts seem to flex so to speak when the engine is running. I turned the engine off and can rotate the timing belts almost 180 degrees... I just replaced them a few hundred miles ago, but reused the tensioners... Could this be my issue? I've seen this on other cars where the tensioners were worn and caused problems

intermittent is normal. 

 

no it's not the timing belts. 

 

i'd replace the oil pump - with new or positively known good one.
