I have a mk1 sporting and need to do head gasket. i was just wondering what size the head extension bolts are and what socket i will need, it doesn't evan look like i could get a socket down there as a tried 3/8 drive 10mm and it wouldnt evan go into the head extension...

and will i need the valve lifter retaining tool from Fiat???

plz plz plz help...

also any other tips i could do while the head is off...

you don't need retainers just lots of hands and fingers and try catch em all when you lift it of and put them back were they came from

the extension is held down with ribe bits if you use anything else like torks you will break them

the actual head is held down with bristal an aircraft fastening

snap on tools might have all these things but the bristal especially is hard to come buy

and again if you use anything else other than bristal on the head like someone else on the forum did you will break them

you will need cam locking tools and the 2 rods for setting the crank 90 degrease off top dead

then once crank is set and cams are locked you loosen the cam vernier loosen tensioner fit new belt

tighten tensioner then tighten vernier then turn over twice then rechek tension

if you need to adjust tension you need to losen vernier first set tension then re tighten vernier again

this make sure you are taking into acount the stretch on the belt meaning the timing will be sot on

all the timing tools you need are available from shop 4 parts

ok cheers will give a go soon when i have then chance and probs just give everything a mighty good clean

The head bolts are Ribe M8, But if you buy new bolts they could be Ribe M9, as i found out don't know why they are different. The Head extension bolts are Ribe M8 as well.

This on my 1.2 16v 1999, I am in the process of doing the head gasket, but the Ribe set i brought from my local car accessory shop, did not contain an M9 so make sure if buy a set it has one.

Good luck and don't forget the cam locking tool and piston rod set.

yh the head is off now i used Ribe bits i am in the process of porting and polishing hopefully gwettin it skimmed on thurs

Just a not the head bolts are a ribe M10 the set of bits i got are not very good they are made by Lazer so dont buy them. I got a set off ebay and they are good quality.
