Yesterday I replaced the timing belt on EJ22 Engine, didn't have any problems at all (lucky I had previous experience on EA82 engine), had a bit of hiccups but all went smoothly, it was 3pm Saturday noon when I was putting together, I realised the rubber seals was falling apart due leaky power steering pump seal (just replaced yesterday as well) as it was too hard to keep them together/one piece, so I put the cover back on without the seals that goes between timing belt cover to rear belt cover/engine block. Now I started up the engine and it has an high pitched squealing noises (didn't have the vee belts for Air Con/Power Steering)... I knew I did double check on all belts ensuring they are all very tight - used torque wrench on the pulleys etc.

 

Two things that I could be suspected are either -

 

The timing belt is too tight? (I had 2nd person to help me to put the belt on but man it was so tight) Or Do I have to loosen the belt tension adjustor as its already on tight spot - I didn't touch that when I did the belt.

 

Or

 

Is it due because of the seals between the timing belt covers?

 

OR

Could be something else? ie bearings?

 

Tomorrow noon I will go to Subaru and buy some new seals for it.

Cheers & thanks.

it must have been a real *************** to fit the belts with the tensioner in place you should back it off to fit the belts the noise could be the belts/pulleys rubbing on the covers the rubber seals missing could affect the clearance

you didn't remove the tentioner and re-set it? if you didn't remove that, then who knows what else could have been skipped in the process.

No wonder the belt was tight. It would be a good idea to go back inside, compress the belt tensioner, and reinstall the timing belt the right way. I don't know how you got the belt back on without compressing the tensioner, but it seems to me you would have to pry on the pulley with a bar or something to get enough slack to get the belt on.

 

 

That might damage the bearings in the idler pulley, causing the squeal? Just a thought???

After driving the Liberty to town 50kms away the noise stopped so looks like it was the tensioner causing it.

 

Got the new seals. fitted them today and its all good now.

Thank you guys.

Turns out to be idler bearing because the noise came and go all the time, got fed up with it and installed new idler and its fixed now.
