so how hard is it to do ???

im ok with simple mechanics but not to good with timing

i cant see the head being a prob to take off but what markings will i need to line up before refitting the head ?

also whats the best headgasket and head bolts to get ? and where from ?

please help

thanks in advance

 

and heres me thinking loads of ppl would know on here

 

we do, we just cant be bothered to type it


replying now........

 

1 the head is heavy as a complete built up unit turbo and manifold
2 new head bolts .a must
3 group A head gasket upto 350 bhp
4 have a good look around befor you start to take things off

 

Things to line up.

Right, the distributor pulley first, turn the bottom pulley till its on TDC and make sure you note where the dizzy one lines up, mark it with paint and on the block or something if you need to, this is because they end up all over the shop and then people time the dizzy in, so if you remember where it was you wont have that issue.


The bottom pulley has n teeth sticking out, just before one of them is a cut into the pulley that goes right through each of the pulleys that are made into one big pulley, this is the TDC mark, thats what you need to line up on.

The cam pulleys have an arrow on them, these need to point towards each other when that mark is lined up.


So turn it like that before you start and make sure you understand yeah?

Take pictures if you want


Its not actually hard to do a head gasket, just time consuming.

you shoul really get the block checked if possible, although often they are ok, and the head will almost certianly need a skim


i like cometic gaskets myself, but they MUST have good lat surfaces or they wont seal, so if you cant get both checked, use a normal gasket instead like a "group a" gasket.



Thats all assuming you engine is fairly standard.

 

thanks guys thats the sort of stuff i was after

im not sure it has gone yet as there is no other sign except a few bubbles in the header tank and its running hot

thermo has been changed and its still getting hot but not right into the red yet

any other ideas ??

also what is the torque settings for the head bolts ??

thanks

 

oh and its not losing water yet

 

If your just pottering it around you might notice that its pretty much ok, its when you come on boost you usually have problems as you'll be forcing boost into your water system you see its then when it should be preassureing up.

 

yup sounds about right

so is it the head gasket ?

 

do a leakdown test if you can, if not then do a compression test

 

what sort of compression should i see in each cylinder ??

 

depends on spec of engine but if like me it still won't show anything up

 

its stage 2 running 336bhp

ill get it tested, but i think my mate will just want it doing anyway

so anything else i need to know, hints etc

also what are the head bolt torque settings

sorry for all the questions, i have used the search but thats no help what so ever
