Default EJ2.5 Timing belt

Im working on my engine and Ive got to take off my Timing belt again.... I hate messing with the timing belt. I guess my problem isnt so much with the timing belt, my problem is with the spring loaded valves pushing the cam shafts while the timing belt is off. Since this is a DOHC engine it is very difficult to keep all 4 cams aligned and get the timing belt back on is the correct place. So my question is, can anyone give me any tips to doing this without a specialty tool?

I think last time I used vice grips to hold the intake and exhaust together on each side while I did it. Any other tips would be great, I havent taken the belt off yet so any preparation tips would be awesome as well.

oh one other thing, how do I know for sure that the engine is at TOC? I cant remember except that all the timing marks should be lined up. Isnt it supposed to be on the intake stroke on the #1 cilinder to or something?

Try two small breaker bars. One bent up, one bent down. Rubber band them together. They won't line up perfectly but you should be able to get them close.

Hehe not bad, ill give it a try

Speaking of rubber bands, if I could get a large enough one I could just stretch it around the two cam gears on each side. It would probably hold them

any others?

Not bad yourself. I like that idea but how can you remove the rubber band after you put the belt on?

Oh, just cut it and turn the motor over.

Ok so now I need to know what is the easiest way to take off the cam pullies. Im think about using a strap wrench and a breaker bar but I would be interested in hearing any other ideas because I absolutly hate messing with them.

Please dont suggest a big ass pair of channel locks to hold the cam pully.... I alreeady broke off a tooth trying that way.....

No I would not hold the cam gear with a channel locks.

Strap wrench works well

leave belt on and hold crank bolt with one wrench and loosen cam sprocket bolt with another

Impact gun

Wrap old timing belt around sprocket, fold it over and hold it with a vice grips.

Thanks, but the crux of this thread was to come up with alternative methods to using the subaru specific "special tools".

I think I will give the strap wrench a try... I tried it once before with a cheap wrench and it broke the strap.... This time I bought a good one that has a strap made of nylon or something

oh as a side note, leaving the belt on and holding the crank with one wrench and loosing the cam bolt with another only works sometimes. a lot of the times it will slip a notch or two.

Do you know how to get the auto tensioner back into its home? I know that you can usualy press it in (I think) and then stick a alen wrench or something through the holes to keep it from expanding again.
