Wildem Posted October 24, 2018 Share Posted October 24, 2018 Im trying to time my 02 wrx and I counted teeth according to the guide written by MEATY on nasoic but my timing marks for the cams seem to be the opposite position of inbetween/ on teeth. Can someone link a good diagram? For example right top (passenger) says it should be an inbetween on the belt but it is actually supposed to be a tooth. Thanks in advance!!!!

Wildem Posted October 25, 2018 Author Share Posted October 25, 2018 On my engine the position it is saying on the belt for both top cams are switched. Passenger is tooth on the belt Driver is tooth on the cam sprocket. This was making me confused trying to count out teeth but i think i got it.

1 Lucky Texan Posted October 25, 2018 Share Posted October 25, 2018 wonder if the heads were decked or some odd size gasket was used? Quote Link to comment Share on other sites More sharing options...

Was one owner car and he never had the head gaskets done. I looked it up and it said it could be tensioner slack and when i started it up it idled fine. I am now facing a much deeper issue as the car will idle completely fine but at 1500 rpm it develops a slight tapping and then at 2k it turns into a knock. It doesnt sound solid and there are no flakes on the dipstick (ran a magnet on it to try and help anything stick) almost sounds like piston slap. I have it running in the driveway now and it has gone much longer than any other ej ive ever owned when they went. Is the collapsing guides an issue on the 2.0 as it was on older engines?

nvu Posted October 25, 2018 Share Posted October 25, 2018 Might be a weak tensioner, it shouldn't move at all when the engine is running. Half a tooth off on one side isn't a big problem. 1 Quote Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted October 26, 2018 Share Posted October 26, 2018 yep, not saying it's 100% but, BOTH of your symptoms could be aweak/blown-out tensioner. there's a youtube video of a knock sound caused by a weak tensioner. Quote Link to comment Share on other sites More sharing options...
