gti gearbox

[jef]

i have a gti gearbox with a very very bad whine which decreases when you lift off . and it also has lost the oil out from the join between the box and the engine, did notice this before going anywhere so should be ok with the lube side of things can you give me any ideas what replacement gearbox will fit ie any 8v or 16v from another golf model, the car is an ( f reg 16v gti gaerbox spec ( 020 )as in haynes manual, also any explaination of why the oil should run out in the first place, any help on this subject would be greatfully recivied

many thanks jef

dont bother your arse with an austin box. trust me!! the ratios are all wrong for the car. and they aint a close ratio box either - plus they will be about 10yr older than your current box!!

you'll be hard pushed to find a good 16v box. an 8v box will do the same job there is only a very slight difference in 2nd gear between the 2 boxes, 8v boxes cost about ?50 - just look in the adverts for ones breaking golfs

if you do go for an 8v box then you'll need an 8v clutch also as the input shafts are different diameter

your's sounds like the diff rivets have let go which usually cracks the casing, hence causing all the oil to seep out between the gearbox/engine join.

16 v boxes are supposed to be alot stronger than 8v's, but should be ok unless your a budding Jenson Button !

What's the score with diesel boxes on the Veedub scene - quite often they're stronger still, but I've only experience with *cough cough * Ford

the only stronger part of the 16v box is the larger input shaft to handle the extra power. but a std 8v will also handle the power without any probs

the problem is the diff rivets which really should be replaced with the diff bolt kit available from VAG

if you wanna compare boxes then here is all the ratio's

Hmmm, I agree diff rivets are a problem that I have seen many times, however this may not be that bad.

The whine could be the push rod bearing (what is effectively the release bearing) and the oil leak could be the push rod seal. Usually you would also suffer with the clutch starting to slip due to the oil contamination.

Both are very easy to fix once you have the gearbox off
