head studs

[chimp007_uk]

hi all,

just getting some bits for fitting my blydenstein head, is vauxhall the only place i can get a set of studs from?

also, could someone put up a list of bits i will need to fit the head please. don't want to forget something when i get round to doing it.

cheers

you can get new bolts from more or less any decent autofactor.



to fit the head

Oil, coolant, gasket set, head bolts, sillycone hmmmmmm thats probably it

[Adam]

And a torque wrench if you dont have one.

aren't the inlet and exhaust manifolds held on with studs and nuts? i knw my exhaust is...

i'm guessing i'm going to need a timing belt as well ;)

got a torque wrench, just need to get hold of a timing light :(

[Adam]

Can re-use timing belt if its not old.
But you've got to remove it anyway, so might as well renew it.
Just reuse the studs/nuts off the old head.

doesn't look to be an option... they're rusted to f**k. and i'm fitting a brand new head, so what to keep everything the same. i don't want to re-use the cambelt.

[Adam]

You could just use some SS M8x30mm bolts to hold the manifolds on.
Thats what i use, just put some copper grease on the threads and hope they dont shear off if you need remove the manifolds.
Its usually just the exhaust manifold bolts that cause problems with snapping off etc.

i'm working at an engineering company at the mo, with a large supply of noths and bolts :) will prob look for studs, dont really want to put steel bolts in a ally head!?! or is it ally bolts in an ally head?!? i get confused.

anyone know what size the rocker cover bolts are?

[Stuart]

M6 * 30-40mm ish

steel bolts in an ally head can cause probs but there isnt much that can be done

[chimp007_uk]

well, just bought some head bolts so they should be ok. will borrow some bolts for the rocker cover from work ;)

i don't want to sound rude stu, but if you are too bust towards the end of the month, would you be able to help me with the head?

[Adam]

Whys that?
I've just bought some stainless steel bolts for my manifolds.

[chimp007_uk]

i think it's something to do with the metals reacting together... thats why you should't use ally wheel bolts with steel wheels and steel bolts with ally wheels

[Stuart]

most alloy wheels have an instert in them that allows the use of steel bolts without the rist of the metals reacting and effectively corriding together

[Adam]

Ooo right.
Never heard that before.

Can you imagine some of the larger tyre fitting companies whacking up wheel bolts with their inch air guns on alloy seats??? Ouch!

i've had it happen to me in my 306, couldn't get the locking nut off... had to have them removed and buy a new set.

as for parts need to change the head, is replacing the hydraulic lifters a good idea? anythingelse people can suggest getting to give the top end a complete overhaul?

cheers

[mikey14sr]

stripping down and cleaning the lifters is a good idea, all explained in the haynes.

[Adam]

Ye, definently take the lifters apart and clean them, make my 1200 completely silent, even from cold.
It sounded like a bag of nails before.

[chimp007_uk]

have found a brand new set on ebay for ?25 posted. seems reasonable... only prob is with cleaning them, is that i'm going to taking one head off and putting a new head on in the same day, don't know wther i'll have time.
