Have a Nice Day? EJ22 Timing Belt

Sooo, I hate getting to know the maintenance of used cars.

I bought a used 1998 OBS from a local dealer a little over a year ago @ 88K. The car currently has a bout 91K and I'm considering having the timing belt done 'early' just to make sure it's good to go. It's general knowledge it needs done at 105K. I've heard it's good to change them every 6 years regardless of mileage and it's been 12.

In our old '95 which was in the family since bought new, I found records of the timing belt being replaced @ 60K in 2001. I thought maybe the water pump or something went bad, so we just had the whole thing done... well turns out, according to Subaru, the EJ22 needs a replacement at 60K.

Source:
http://www.subaru.com/content/downlo...98SchedFed.pdf

So, that's why we replaced it in our '95. The general 105K mark is for our EJ25 brothers. Considering I have no idea if the timing belt's been done at 60K, I might be running on super borrowed time in the '98. If it was changed at 60K, I'm good to go til around 120K, which is far off.

Should there be any markings saying when the belt was changed? (if it ever was). I searched and found some people saying there was a sticker on their hood, or possibly a sticker on the timing be cover. Mine has none.

My other option would be calling the two or three local dealers around me to see if they have any records with the VIN number.

What should I do?

Well change it! That way you have a definite starting point to monitor wear on the parts and you can start your own records for piece of mind. The EJ222 is a good solid engine so spending a few $$ now to freshen up the vital parts will pay off when you trip 200K failure free

Just change it. It isnt hard and it is good ins. BTW when you do it the t-belts from NAPA are manufactured by Gates which is a good company. I usually just get mine from the dealer though. They arent terribly expensive. Be sure to change the t-stat and water pump too since youll be in there anyways.

My 1997 Impreza 2.2 was dealer maintained by the previous owner and they changed it at about 70K. When I did the change again at 120K, the belt looked good...so I think just by looking at the belt it will be hard to tell. Your best bet if you can find service records from the dealer.

On a side note, it would be good to change the front crank seal and reseal the oil pump. These are common leak points on these motors and they are right there when doing the timing belt.

Called the three dealers around me today. One had no information on the vehicle besides when I got it aligned there last summer... even though it was sold from that dealer. The other two service departments were busy.

I checked the cover and the bolts don't look like they've been touched ever or recently. Looks like I might just have it done anyways.

Any other opinions?

I really would fit it was a non-interference engine. I don't want to mess anything up. I do everything else myself on the car and to be honest, it doesn't look that hard.

Taken striaght from the PDF link i gave you:

Quote:
Unlike the 2.5, the 2.2 engine is not an interference engine. If the belt breaks or jumps timing, the engine probably will not sustain any internal damage.

^^Found to be incorrect

SOHC engines became an interference type in 1997, when compression ratio was increased, along with other changes.

Hmmmmm.... not saying you're wrong, but we have conflicting data here. The PDF states the year it was produced was around 2000, so this would have been after the 97/98 MY crossover thing wiki talks about.

Quote:
The SOHC EJ Subaru boxer engines were non-interference engines through 1996, run by a single timing belt driving both cams (both sides of the engine) and the water pump. Because they are non-interference engines, if the timing belt fails, the engine of the models up to 1996 will not be destroyed. The oil pump is driven directly from the crank shaft and the waterpump by the timing belt. All DOHC and 1997-up SOHC EJ engines are interference engines, if the timing belt fails the engine will likely be destroyed or the valves & piston will be heavily damaged.
Linky:

Edit: Post 4 on this thread someone states it's interference too.

Hi cmiovino,

I have a 1996 impreza outback 2.2 with 174,000 some miles and just changed the timing belt along with the water pump, the tension-er and all the pulleys as they were bad too. I resealed the oil pump, definitely needed it..lol..., then sealed the new water pump up as well. But, there is a small O ring on the back side of the oil pump that goes flat and eventually starts allowing oil to seep and come out the bottom of the center timing cover, so replacing that is definitely a good idea.

As some other people have said here, the timing belt on these 2.2's are pretty easy to change, just have to make sure the crank sprocket is lined up as well as the marks on the belt with the inner timing belt covers on both ends and you are good to go Also, if you have a torque wrench then tightening the bolts to the right amount is good as too little torque or too much can cause future problems. I hope that changing this belt and stuff goes smoothly

If you have any other questions don't hesitate to ask

Thanks. The PDF is probably wrong. I'm getting the same info on RS25 too.

Thanks, subi400.

I'll see about those seals. I'll probably just have them replaced for precautionary sake.

Yeah it looks like that statement in the PDF is incorrect. Some of the years of the 2.2L engine are interference engines.

Ok, prices... dealer vs. SubaruGenuineParts

Timing Belt
Dealer: 79.95
SGP: 58.52

Tensioner (EJ25 only listed)
Dealer: 149.95
SGP: 109.76

Waterpump
Dealer: 99.95
SGP: 73.16

Thermostat
Waterpump: 16.95
SGP: 12.41

Other various gaskets and seals (probably just get at dealer):
Water pump gasket
Thermostat gasket
Cam seal gasket ~$8 from dealer
Crankshaft seal gasket ~$8 from dealer

I want OEM only stuff, so there's the prices. Anything else I'd need?

What about ebay 'kits'? Some list part numbers, which appear to be from Subaru... so are they really OEM?

Also, anywhere else I can get the parts cheaper?

Pics of the TB:





No visible writing on he outside of the belt... so it's probably the old one. Looks used, but not terribly bad. Does it look normal?

I am doing a timing belt replacement on my 06 impreza and found all three idler pulley bearings showing wear enough to warrant replacement. Mileage is at 109k.

Just something to keep in mind.

You have to replace every pulley in there too. Failure to do so may jeopardize your engine since it is possible for an older pulley to seize up and cause your timing belt to jump.

This actually happened to a friend of mine.

Whenever I do a timing belt, I replace everything I can reasonably get to including the front seal on the oil pump.

Belt
Water Pump
Oil Pump Seal
2 smooth idler pulleys
1 cogged idler pulley
Tensioner w/pulley

Thanks for the responses guys.

What if all the pulleys are spinning good? IIRC, they're VERY expensive to replace. I only drive the car about 3K miles a year.

replace them. Espescially the cogged one. It has lots of stress on it.

Many of us from the USMB buy the ebay kits for the idlers, and get an OE belt and waterpump.

I have to say, I've gotten genuine Subaru waterpumps with the cheap ebay kits.

So the idlers from those kits are legit?

Just had my 2000 impreza timing belt changed today. Car has 92k on it and the dealer said it had 2 cracks in the belt. I asked him about replacing the Water Pump as well he said they didnt do that with tming belt changes, which makes no since to me. Anyway i would recommend getting your belt changed before the 105k mark on the phase 2 ej22.
