**URGENT**help required !!!knocking sound
car is a 2000 uk model with full dealer history and only 41k...not chipped or messed with.
it has just started to give a heavy knocking sound from the engine,if i leave the car for a while and re-start it it knocks very hard for the first couple of micro seconds then quietens down,as the oil presure builds up...
i doubt it's the big ends/crank bearings or such a low mileage engine ???
do they have hydralic tapppets that could be stickin ???
any advice greatly appreciated..
i live in county durham if anyones local ..

mine had same knocking, does it come from around the middle part of the engine? if it does get ready to call somebody who does rebuilds, just got mine back from a.p.i who done a stearling job but it is not cheap!!!

just dropped oil into a brand new/clean container to check for a ny metalic debree and guess what.....
crystal clear,put my hands in and removed em and it was as good as baby lotion,no debree at all
the hunt continues

My 93 WRX just suffered (big style) with the crank going (I'm looking at a pretty major bill right now). I had a knocking sound coming from the middle of the engine around 2-3,000rpm although it never quietened down after the car warmed up.
Best bet is drive it calm and get it to someone in the know asap.
Hope it all comes good,

Have you replaced the MAF Sensor at all??
Now I don't run with what I'm about to say, but -
Some people claim that the MAF on a 2000 Impreza is suspect, the ECU is also as thick as Vicky Pollard and cannot detect a drift out of tolerance ..... this then knocks the Big End bearings out!!
As I said .... its what others say .... I think its poppycock, but you may wish to take it on board??
