Hi all
Just got a 58 reg 1.4 16 valve grande punto.

It has done 68k and had not had a cambelt done as far as I can see so I thought I would give it a cambelt and water pump to make sure.
Treated myself to the proper timing tools and an e-learn cd plus a haynes manual. While waiting for these to turn up did alot of reading on how do the cambelt on this model and found the general opinion is that when you remove the cap of the variator it should lose about a tablespoon of oil. To my surprise mine didn't lose any.

When my missus drove it home she said it was poor on power in low revs (I dismissed this and put it down to the fact of her being used to driving a diesel and not revving the engine much) reading up on this it seems that on the larger engines the variator should be on (pressurised) on lower revs up to about 4K. Which is supposed to improve the torque at lower revs.

Does anyone know if this is the same for the 1.4 16 valve engine and could the fact that the variator didn't lose any oil combined with a lack of power at low revs add up to the variator is not coming on?

Anyone know of any experience of this problem or an easy test to see if its working? and if not how to fix it.

Thanks all and sorry for the long explanination.

Easy to check.

You need multiecuscan software and an ELM adaptor.

From there you can check variator position / cam position + desired position / timing / fuel trims / PDA valve position etc. (y)

are the 1.4's that low on power at low revs ?
her old one was a 2001 1.2 16v and that was quite nippy
perhaps I should get her some heavier shoes:D

I have an elm 327 and Ive got an old version of fiat ecu scan would that show me if its working

if it wasnt would it give a fault code?

thanks
Kev
