Legacy engine is the 2.2 liter single overhead cam engine. In fact, this was the only Legacy engine from its introduction in 1990 until the 2.5 liter engine came along several years later. 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.
i would go back and check the timing
once the timing is right you can do further testing or test drive.
good luck paul
i will give you a great web site to look over and will give you better info than your chiltons.
Truth about Subaru 2.2
hope you like this site.
we use these engines in dune buggies and have great luck with them
feel free to contact me for any other info you might need
later
paul
that is realy easy
because the belt is off you only have to pull #1 spark plug and stick some thing in the plug hole had turn the engine over by hand till you feel the piston come to the top.
and without the belt on there isnt a compression stroke.
later paul
yep and to double check it you count the teeth between the marks to the crank.
did you see that on the web site?
let me know what you find
paul
did you check the ign timing after the you set the cam timing
it sounds like your timing is retarded and need to advanced.
this would explain the cat getting so hot.
paul
with a timing light with it running
oops
1990 Legacy has no distributor, but twin-coil ignition, fired 2 cylinders at a
time. When one cylinder is on Power stroke, the other one on that same coil is
between the Exhaust and Intake strokes, so the spark is wasted and does no harm.
A stall at speed, possible accompany by backfire through the intake, is usually
ignition trouble, often defective cam and/or crank sensors. Presuming your
engine will restart and run OK once it cools down, this means the engine itself
is OK (you have not jumped a timing belt, for example). When cold engine, if you
have good power, this means the fuel system is OK, and it is ignition. Coils are
firing at the wrong time, so backfires. Hope you are using the correct
resistor-type spark plugs for your engine, or you will get influx-firing.
you better do a compression check on all cyls next
could you please rate my advice thanks
did you get a compression test done
and if so what was the figures ?

It has engine damage most likely due to the broke timing belt its a interference engine and probably bend valves

Usually answered in minutes!
we bought it acouple days ago & on the way home the water pump froze & broke timing belt
how would you figure out where exactly tdc is?
exactly what was done, we took it back apart & it was correct
Thats what we did, We turned it until piston came to top of compression on # 1 & started fom there twice, I have no idea what is going on. We just bought it & it had power on the way home & then it started missing & then the water pump & timing belt went, all we did was change the water pump & timing belt. We also had to clean the cat because when we took it to wash the engine on the way home The cat was trying to catch fire # 1 cat right off the motor. So we also cleaned that cat out. But that is it, now you can start it up & put into gear & floor it & it barely moves forward or reverse. & sounds absolutley horrible. Next step will have to be a nother motor.
How many teeth should the belt have?
can you do that with the belt off
it is not an interference engine, what what i was told & the chiltons manual
how can i get tdc compression stroke with the belt off?
thats great but, how can we find tdc, the belt was off & I dont know where is was positioned when it broke, we lined up all the notches & thought we found tdc by using a screw driver & feeling for pressure on # 1 CYL, but no such luck
so, how do i find tdc cpmression stroke since the belt is off?
so line up the 3 notches on the pulleys & line up timing belt marks to notches
did all this twice, saturday & sunday. NOTHING, ran horrible & cat caught on fire, dont even have enough power to back out of driveway
so how do you check the ignition timing?
so with no distibutor, how do you adjust the ignition timing?
your advise is helpfull, I will rate it but my problem is not fixed
we are getting it done this weekend will keep you updated
