engine knock 2002 wrx? PLEASE READ!!
i have 2002 wrx impreza uk car.
i have a heavy pinking type of knock when i rev my engine steadly but is not there when i blip my throttle and is not there on tick over. HELP!
I dont want to take the engine out at the moment, unless somebody can point me in the right direction to the problem? any commen faults?
the pinking type knocking noise comes around 2000 onwards through out the rev range.
this knock doesnt happen on start up or at idle, just when reving steadly.
thanks very much with any help regarding this matter.

hello simon,
alittle more info for you, if you rev it up steadly and let go off the throttle the knock noise goes, and if you keep at required rpm the knock noise is present until you let the throttle off. Havent checked the cam belt tensioner yet but is there a possible problem with this?. the current mileage is 68000. i replaced the cambelt and tensioner at 54000. no problems until sunday just gone.

If you fitted a new tensioner,torqued up the retaining bolt correctly and removed the retaining pin 14,000 miles ago,it should be ok but worth checking again.
Might also be the front pulley bolt loose and the pulley chattering on the keyway of the crank OR the dreaded big end failure.
A big end bearing which is just starting to fail will be evident around the 2-2500rpm range.
Might be worth getting a specialist in your area to have a listen to the noise.

Sure it’s not worth a second opinion before you strip the motor, get a garage to have a listen. As Mick said check the oil and also check the filter, cut it open.
As to what bearing picks up is totally dependant on the cause, as far as det then it can be any. If oil starvation issue or break down then “usually” the first to suffer is the furthest from the pump..
