Gearbox

94 wrx import, When it is in 1st gear and I boot it and change into 2nd I sometimes get a little grinding or clipping noise only when Im driving it hard, If driving normal and changing its fine.

Is this something to worry about?

Re: Gearbox

Could be. First thing I would do would be check the gearbox oil. If it hasn't been changed recently get it changed for a god quality oil like Motul or Sylkolene. Also check for any debris in the oil if you do change it.

However, sounds an awful lot like a worn synchro to me, which sadly are fairly common on scoobs (esp classics) that are driven hard. This will require having the box out and said part replaced.

Re: Gearbox

Am gonna get the oil changed at weekend and see if the old has any debris in it. Doesnt do it all the time though, could it be to do with the clutch as that is sticking down sometimes not all the time again, but when it does I have to flick it up from underneath with my shoe

A heavier as in a thicker grade oil will stop the crunch aswell but if the syncro worn beyond the point it will come back and the only option will be to replace it and thats box out you would see alot of shavings in oil if syncro well worn strain the oil and check for bits
