Title: new engine!
Post by: danyo on 29 June 2012, 23:02
after a few weeks off the road, i finally found a donor 1.8t 20v auq engine!

got it back yesterday and everything seemed fine.....

driving back from work today, sounded like someone had fitted a supercharger to my car!! it's the exact noise 1 makes! any suggestions on what it could be?

also in 5th / 6th gear the noise gets alot louder and the gears sort of grind if i drop it down a gear!?

The whine could be cam belt too tight or maybe they have not filled the gearbox with oil.

is yours 5 speed or 6 speed?
if its a 5 speed then i recommend upgrading it to a 6 speed as there stronger.

its a 6 speed and was told there pretty weak! just had a new turbo put on and apparently that has caused the problem?
Title: Re: new engine!

new turbo cause gearbox problems that's a new one, didn't go kwik fit did you?
and the 6-speed are the better/stronger box.

that's what i was thinking! no i went to a mate of mine, but he's not the sort of person to give me any bull!

could it be something to do with bolting the gearbox onto the new engine i have had? maybe they guy that fitted did something wrong?

a new turbo wouldn't have killed your gearbox

you recon it wasn't fitted properly to the new engine then? am i right in saying you shouldnt need to top up the gearbox oil, cus apparently it lasts forever? or is that bullsh*t?

gearbox on its last legs.. raggin it round with a new turbo finished it off?
Title: Re: new engine!
Post by: dan2252 on 30 June 2012, 14:21
or maybe just you were unlucky and gear box was gonna go anyways.. a new turbo isnt gonna kill your box, plenty of people go put 300 bhp through a mk4 box and im sure theres would go straight away if yours did. just check gear oil, remove the 17 mm allen key out of the front of the box and if oil runs out its fine. if loads of oil runs out quick its over full so let it go till its slowly running out the box, check the oil in the box for bits of metal, but like a guy said earlyer on here not your cambelt over tight is it? your mate know owt about cars?,

Check and make sure the gearbox has oil in it first.
Title: Re: new engine!
Post by: dan2252 on 30 June 2012, 14:43
check the oil like the guy above said. coz correct me if im wrong but when oil levels are low on boxes dont they normaly kill the 5th gear first? because its first one to have no oil around it because its at the end of the box?
Title: Re: new engine!
Post by: danyo on 30 June 2012, 17:06
the box was fine before the new engine and turbo, but then im not mechanic to say it was on its way out anyway! and no havent been ragging it, wearing the new turbo in first :)

i will check the oil in the box and see what state it is in!

whats currently the cheapest option? get it repaired? new one? spent nearly 2k last week getting it back on the road so money is a bit tight at the moment!

Makes you wonder if they have put something together wrong  :undecided:

Try and find a secondhand gearbox.

Nope all were 5 speed, Leon Cupra was 6 spd however, seems strange the Vrs never got the 6 speed I guess it was all down to keeping the price down.

**UPDATE**

driving along today and there were some new noises going on....

driving around a car park, and there is a really load grinding noise!

i have also knocked it out of gear into neutral while the whining is happening, and originally it did stop. today it didnt, kepy making the whining / grinding noise even in neutral!

any suggestions? or is this all still gearbox related?

Could be a drive shaft?
