How To Change The Vvtl-i Screws

[juan-1]

os tornillos,el coste son 1.5 € los 4

retiramos la tapa

vamos quitando cosas...todo con la 10

ese agujero no se para que sera..

estan un poco fuertes los cabrones..

la freidora!!

los arboles de levas...el primero que se ve es de admision y el del fondo escape...se puede observar el sistema vvti

y alli los tornillos..

llevan un par de apriete,pero no los he querido apretar mucho,estan bien apretados...

metemos la freidora y listo..

aqui los tornillos para que veais su desgaste...

como veis se a empezado a comer hacia adentro un poco por donde termina el chaflan del tornillo comiendo hacia adentro...tambien el de admision es 2 milimetros mas corto..

Good, one is the screws of vvtli .

one is a motor with 48.000km and to verify the wearing down of the screws

the first screw of the left is of admission and the one of the right is of escape

the one of admission is the one that worse was with a wearing down in I circulate very rare

it is very easy to change seeing it mainly the images, I recommend its verification to you

How u doing lads???

I'm an aircraft technician by trade and that doesn't look too dawnting but.............. how many of those screws are there??? only 2 or four? What do they do and is it important to keep them in top condition. And where is that lift bolt???

Would really like to know as my engine has done 113,000miles and would like to check these out if they are very important to the engine cheers!!!!!!!!!!!!!!!!

Just have to say many thanks juan

Today i followed your pictures they are spot on and took the top half of my engine off nothing to it really easy to follow only took 15 minutes.

My screws are worn not too much from the end but they are marked around the bolt so going to order some new ones and replace them!

Again thanks as i would never in a million years look there!

Cheers again

[Silver_Shadow]

[mac12]

That's great. Thanks!

This is a ridiculous observation and nothing whatsoever to do with the topic in general, but the town shown on the satnav in the first picture - Watermael Boitsfort - is twinned with the town I grew up in, small place called Annan in the South of Scotland, populated by 8000 inbreds!

I left the place as soon as I could.

If you guys are interested, check out my post titled "Changed my lift bolts today" and see a pic of what came out of the engine...

Is there any torque settings? or do you just screw them as far as it goes?

[MarcTS]

I think Juan is the only one here who has changed them himself, so I guess he'd have to come back and let us know.

[badboyts]

had a price of mr t 92p each

he said torque between 10 - 15 kn

part number 90105-06293

[Silver_Shadow]

So does changing these bolts improve the performance at all?
