2.5 diesel valve guide removal.
Big question, how do I get them out? I've removed the valves but have no idea on how to get the valve guides out. Any tips?

No idea mate, but on 24 cylinder Wartsila ships engines, we used dry ice and a sliding hammer tool. (I supect that might be overkill for a 2.5 diesel)

They need to come out so I can scrap the ally in the head. It's badly chewed a valve at some point and is totally scrap.

the valve seats likewise,CGATCX25GTITURBO wrote:put the head in an oven for a good while get it very hot and they will fall out with a good tap
although as you are scrapping the head you should be able to just drift the guides out cold,
how much do you think your going to get for the bare head anyway, ( is it worth the effort ?????)
my last workshop landlord does cylinder head work for a living, and to heat heads up he has an electric cooker hob he sits the head across the rings for a while,
till you can fry an egg on the head,

Re: 2.5 diesel valve guide removal.
It's probably not worth doing really. I do save up scrap ally and weigh it all in when I have enough, it makes a nice bonus!

If it's for your scrap bucket and you have the time, why not!
When I was in ship repair, we used to repair broken ships gangways and I always stashed the bits I cut off and saved them for a couple of months before the trip to the scrappy. A syou say, a nice little bonus. (I won't mention the white metal bearings, the brass and copper pipework or the stainless tanks)
