I got mine done at a little company under the itchen bridge, they are brill. They were vapour blasted which is high pressure water, see my m30 thread for the results.

I can't recommend them enough, proper old school engineers, amazing attention to detail also. Cash and cheap also.

There's no substitute for elbow grease. I did my inlet, TB and thermostat housing with a dremel and wet and dry, finishing with a fine wire wool.

Media blasting will get them clean but won't give them a shine.

Nice one jim, how much did they charge ?

Cloggy - that engine looks great, mine will come out in the winter for a full sort out like that, I need to get a dremnel, is it just 1 tool in it that shines them up like that ?

I started with a dremel with wire wheel attachment which cleans it up nicely but obviously scars the metal. I think I started sanding with 120 wt and dry, working up to 2000 and then the wire wool. The TB was quite quick and easy to do, the thermostat housing less so!

its cheap, i left a large batch of stuff and it was a £100 - see my m30 thread mate

dremnel - pop over to B+Q in Havant and have a look at them - well well worth the ££ IMO - i use mine all the time mostly with a little cutting disc on

There are drill attachments that are like wire wheels but are made of plastic strands instead. They seem to work really well on aluminium.

I think just blasting looks best and is closest to the factory look, I'm not a fan of shiny engines. I'm toying with the idea of trying a clear powder coat over a few bits after blasting to see how that looks.

Also a question - has anyone done or got an idea of a cost to replace all the engine pipes and hoses ? I might maybe label and remove them all and give a good clean whilst its all apart

All the coolant pipes, minus the metal cross pipe that goes behind the fan are just over £100 from the dealers. The vacum pipes are way more expensive. If you have the two pipe setup that goes from the servo to the TB its over £100 on its own. Add that to the rest and it starts getting pricey.

Old hoses can be bought back to life by gently rubbing the crusty outer layer away with some fine wet and dry.

I would replace if they are looking old and crusty. Last thing you want is an old perished coolant hose to burst.

I'm not talking perished or damaged, just surface gunk and where they've faded.

You said crusty, crusty = old and perished.

Why take a chance on something of little relevant cost that can potentially cause a break down?

Mine arnt old perished or crusty, a bit faded and grubby but no splits or light cracks, but there are a fair few pipes in there once the inlet etc is removed, hence the price question, but its then remembering them all, I might get a load if jubilee clips, then maybe do pipe by pipe and re fit, with a big bucket if soapy water, wet dry paper and rubber treatment ?

I'm not taking a chance with anything. All hoses were checked and in good nick, just crusty, which in this context = discoloured and dirty.

if you want a factory look, get it all nice and shiny


.....then coat it in a layer of yellowy wax that becomes impossible to clean off! :mad: :wink:

Sjoerd! I was going to give you a call in the near future, I got your number from your wanted ad on Marktplaats. Did you get any seats?! I'm going to England on Saturday and will pick up the last couple of bits there and then apart from a few small jobs it's pretty much good to go. I'll let you know, cheers :)
