sorry for the dealay guys and thanks for the warm welcoming. Right now i am using Castrol GTX 10W30. Would a different weight oil help this? I did try some "Gunk Valve medic" which someone suggested on another site. But sadly, this did nothing for the problem. I don't seem to have an oil leak as the oil is always full and none is coming out from anywhere. I have no idea what this is...but its not the usual subaru tick...we have 5 subaru's right now and about 6 others in the past. any body have any other ideas or suggestions? Jeff

I have a 93 impreza wagon. I have an annoying clicking/tapping sound when the engine is cold. After about 15-20 mins of drving...the sound seems to die down some. Also, it goes away after changing oil for about 1500-2000 miles then it comes back again. any one have any ideas as to what it might be? clogged lifters? ( maybe take them out and clean them) piston slap? ( i know the ej25 and 22's and 20's have this problem) timing belt tensioner? ( don't know if mine has the crappy one or not) loud injectors? ( i know they tick, but this loud?) old age? ( 173,000 miles is a lot) any other ideas? this things sounds like the old EA81 in the loyale's and GL wagons until it warms up. thanks in advance for the help guys. Jeff Buchanan
