c20xe valve guide replacement?

[turbo-boy]

hello anyone here replaced the valve guides i hav 4 broken ones in my head and i need to replace them. i can get the guides for £1 each,i beleave that they tap upwards out of the head and when your putting them back in you hav to freeze them is this correct?

when i replaced my valve guides it took a lot of heat to get them out

they need alot of pressure to push them out dont just hit them with a hammer

try and get a bit metal rod machined so that part of it sits inside the guide and the rest sits on top so when you do hit it it will nt collapse down

mine were removed with a press after having a bit welded so there was plenty heat in it

i tryied to tap one out today give it a good bit of heat but the out sides where just breaking up. think imn gonns leave it into machine shope the boy charges 5er for each guide to be replaced labour that is

Its a specialist job, take it to a michine shop/engine builder.
The guides might only be a quid each, but in the wrong hands you could ruin a £100 cylinder head.

yea for the price it would be silly for me to do it myself and maybe bugger up my head lol. thanks for your advice my friend

like i said better with a press and a hell of a lot of heat

We used to just freeze them and then press them in streight away, no heat involved when we did it but they had to be fresh out of the freezer and into the head within a few seconds

i used heat to remove them not to put the new ones in
