Hey Dude just letting you know just posting a problem like with with little description is a way to just get flamed. More info would be good if you would like help but if you aren't too good with cars just take it to a mechanic.

i asked my auto teacher in automotive class and he said its to do with the clutch and the gear oil the oil is the right type 75-85w

It has nothing to do with your oil, sounds like your clutch is not disengaging properly so try your master cylinder or slave cylinder for leaking fluid as it sounds like there is not enough pressure it may even be the clutch pedal.

Also reverse is a straight cut gear not helical like all the others so it should be that slight bit harder to get into gear as they are not meshed like a helical gear, just use your muscle and throw it into reverse and you wont have a problem.

he said the clutch may be dragging and if the oil is low or the wrong type he said it may spin the gear faster and been strait cut it will grind and not go in to place like the other gears but he said the clutch splines could be sticking or the slave isnt pushing out enough

Solution: Take it to a Mechanic. Mechanic provides you with a fix, problem solved? Then you know for future reference so you can diagnose it yourself.

It's only reverse haha mine started crunching when the clutch was on it's way 260kw and stock clutch not a good mix

there might be a small air bubble in the slave cylinder im going to check that this week end

My non-turbo 34 does the same thing most mornings on cold start, goes in but makes a horribly grinding/whirring noise.. pop it out of gear, pump the clutch a few times and put it back in, no worries. If I pump the clutch a few times BEFORE trying to put it into reverse for the first time, it doesn't do it.

This leads me to suspect there is a tiny bit of air in the system..

yea i am checking for air in the system tomorrow
