#7180 of 8644 New Timing belt now I have an Engine miss by k1morrow

Mar 12, 2007 (11:01 am)

I recently had come into my posssion a 1992 subaru legacy 179,000. It needed a timing belt the teeth were gone. so we put that on and the car starts now but has a miss. to my knowledge it did not miss before the timing belt issue. Have checked two injectors on 1 and 3 cylindars but not two and four. Have put new plugs in also. It has power surges at high rpms 50 to 70 mph. and while driving in town it will die at stop signs ect if you don't keep the rpms up. I think the engine is a 2.5 liter 16 valve 4 door sedan. Thanks k1morrow

Whoever did the belt probably have it off by a tooth or 2 I'd make them re-check the timing marks.

mike, I have been told they will not start even if they are off one tooth, is this true? k1morrow

nope if it's off by 1 or 2 teeth they will run but won't run well. They'll run as you described.

Yep. I had mine off by a tooth for a while. It ran and idled without any problems, but not as smoothly as it did when I corrected the problem! Two teeth? Probably will not idle well at all.

Thanks mike for the info I will be trying to get this corrected? Does it require a complete tear down as they did when putting the new one on? k1morrow

If the timing belt is off 1 0r 2 teeth will everything have to come back off( radiator, electronic cooling fans, belts ect.) to get the marks lined up correctly? any thoughts on getting things lined up right with out a manual of any kind? k1morrow

Regrettably, yes, you have to dig all the way back in there. Lining up the timing belt is incredibly easy, assuming the sprockets are marked as with later model years:
 
First, rotate the crank (with belt on) until it is in TDC position (should be a mark on the sprocket). Then, remove the tensioner and pull the belt. Align the cam sprockets (is this a SOHC or DOHC engine) so that 1), on a DOHC, the sprocket marks are facing each other - top pointed down, bottom pointed up and directly at the mark on the upper sprocket or 2), on a SOHC, the marks are pointed up (I think - better get confirmation on this). Reset your tensioner with the pin (or appropriate method) and have it in place to set tension on the belt when you have it reinstalled.
 
Then, you set the point of the timing belt that has the dotted line (lines should be on the back - smooth side - of the belt if it is new) on the crankshaft sprocket so that it lines up with the TDC mark. Working toward YOUR right (toward driver side of car), thread the belt onto the idler pulleys and sprockets so that the next line (all the rest of the lines should be solid) runs directly across the top of the sprocket, then down so that the next line is directly across the right side of the lower sprocket (if DOHC). There should be an alignment mark either on the sprocket or on the back of the plastic housing for this one. Continuing, thread through the idlers, water pump, etc, SKIP the last idler (should be a toothed idler) and align the marks on the cam sprockets to the left side. After you have done this, the belt should be on other than the one skipped idler to the bottom. At this point, pull the belt up so that it is engaged on that idler. Verify that all the marks are still correct, THEN release the tensioner. At this point, you can rotate the crank and move all the camshafts in time. I usually do a full rotation - slowly - and verify that everything is in perfect alignment when it comes back around to TDC. If it is, close it up and call it good!
 
Take it slowly and carefully, as bumping the cam sprockets can often send them "snapping" out of alignment. It can be a frustrating job with just one person (actually, it can be frustrating even with MORE than one person!), but it is fairly straight forward to get things together properly.

My Contour and my Accord both rejected the Bosch plugs. The Contour ended up with the OEM double platinum Autolites and the Honda got NGKs.
