You could try Redline Lightweight shock proof gear oil. Does wonders for slightly worn synchros.

Drain old oil overnight... smash in 4 quarts of Smurf blood. Cross your fingers.

okay sounds good i appreciate the help mate

Did it help any? I also have some 4th syncro issues, double declutching is becoming a yawn.

Definitely try Redline oil before doing anything else - don't let anyone tell you otherwise!

You can try different oils but it's a short term fix, the box will eventually have to come out, I'm starting to have 3rd syncro problems.
