Ok for those of you who drive an 01 WRX bug eye heres a few questions...

How much oil does your car go through? I got mine serviced by a top mechanic (Well i think he is anyway haha) Used castrol 5w30 Edge, same as he uses in his 06 pignose...

Its done just over 6000 kms since service, and today while it was cold i checked oil....just below the bottom dot, started her up for 5 mins BARELY reading at all..Went on a frenzy calling people trying to figure out WTF happen. Drove it to the servo to see if they had any of that oil while i was there i decided to check the level again and it seems to have gone back to normal.

So how much does yours use and is this a normal rex thing or cars in general?

Second question is on idle there is a slight offbalance almost as if one of the plugs is missing BUT its not all the time and its not as vicious as a miss, Could it be time to change those plugs im not 100% sure if the platnums or iridiums got changed at 117 000kms which is when the timing belt etc etc was all done. It now has 156 000 kms on the clock

Any enlightenment to this situation coujld be greatly appreciated

Had a bleed valve for about 5000 kms but had been removed since and NO this issue did not start AFTER it was fitted and was only set to about 12psi
