My 97 legacy stopped running timing belt jumped could I possibly have timing off 180 all the marks line up?

Not entirely sure what you're saying here?
Since the cams spin at half the speed of the crank, they'll all line straight up every other rotation.

When they're not lining up, the crank will me straight up, the cams will be straight now, next rotation they're all straight up.

 

If you're saying your belt broke and you just replaced it. And now the motor won't run, you have bent valves. The 97 is an interferance motor.

Belt did not break just wouldn't start drove it home the evening before! I have been in this motor several times water pump and new belt before with no problems always fired right up when I was done.

Rally Suby must not have an answer. As to the discussion on hear about interference and non to the best of my knowledge all 2.2 subs are non interference motors.

the 2.5 was the first interference motor produced! If this is wrong please enlighten me! Next I'm a newbie to this site but not to Subaru could you offer a little more than the valve are bent canned response. Thanks

Incorrect.

 

All EJ22's were NON-interference from '90-'96. In the '97 model year they upped the CR (different pistons, I believe) which caused them to become interference.

 

To the OP, please double-check your timing. Once you confirm the T-belt is correctly installed, see if it'll run. 

Maybe your tensioner let the belt slip or a pulley seized up??

 

GL,

Coged idler pully 97 could be ether way right on the cusp there was roller hydrolic and roller solid valve trains the soilid is interference for sure the hydrolic I don't think is

as already stated 97 EJ22 is interference unless it was previously swapped - all 1997-2001 EJ22's are interference.  it's only 1996 and earlier that are not.

 

 

 

My 97 legacy stopped running timing belt jumped

 

install a new belt, line up the marks, and fire it up.

if the belt and marks are good, then do a compression or leak down test.  sometimes you can just slide your finger over the spark plug hole and tell if a motor is building compression or not.

 

could I possibly have timing off 180 all the marks line up?

no. more likely is you used the wrong mark on the crank - there is another mark on the crank sprocket that confuses some people who use it mistakenly. 

 

(i answered "no" - i guess in truth of course you could have the timing off 180, i'm not there to see it)

Perhaps the OP is asking if the crank gear makes two rotations to one cam gear rotation. This would be the case with any 4 cycle engine and it would be possible  to have the timing off 180 degrees. I don't know what kind of engine damage would occur on his interference engine if he had the timing off like this.

if by "all the marks lined up"

he means "all the proper timing marks are exactly where they're supposed to be"

 

then no, he can't be off 180 degrees.

So I am going back thru timing marks etc. and hopefully I just did it wrong but marks seemed to be off again. should the white marks and all timing marks align every other revoloution?  would like to know if that is true.

No, they won't. Every rotation the crank will obviously be pointing straight up. Since the cams spin half the speed, they'll only be straight up every other rotation.

Since the subaru timing belt has somewhere around 220 teeth that means all the white marks and all the cam/crank marks will only line up every 440 or so revolutions.

Deleted. Seems right to me this morning.

That motor looks new!

Great pics for the member.

belt markings (white lines) are for installation only and not needed at all, they're just an aid.  after the first revolution they won't line up again except once every few thousands revolutions.

 

1.  line up the cam sprocket timing marks.

2.  line up the crank sprocket timing mark (MAKE SURE TO USE THE CORRECT MARK, some people use the wrong one)

3.  release tensioner

4. rotate engine by hand and see if the cam and crank sprocket timing marks are still perfectly lined up.

 

***Notice you can install the belt without marks, they're not needed.

if you follow those directions the timing belt markings are completely useless and unnecessary.

 

think about it this way - the engine does not "look at" or "see" white lines on a timing belt, they're completely pointless mechanically speaking.  if it wore off or you installed a belt without the lines the engine would certainly still run.

Well I think I found the problem the belt tensioner seems to not be doing its job and is allowing it to jump timing right away.

Going to get a new one, this has happened to this vehicle twice now and had to take a long look a possible problems.

                                                Thanks for all the great help! I will post with hopefully a running Boobaru.
