Jive Posted April 9, 2007 Share Posted April 9, 2007 Hi peeps, as some of you may know my engine is partially stripped on my NA and I've got the opportunity to clean my air intake manifold - I don't think it's ever been touched apart from the day it was placed in the engine so a fair bit of grime has built up over the years. Anyone suggest a good way of cleaning these sections up? I've tried using Autosol and Autoglym Metal Polish on the bits circled but it's not improving it a great deal (although I can see some improvement) but any ideas on how to clean really well would be appreciated T.I.A. to lots of elbow grease methinks Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted April 9, 2007 Share Posted April 9, 2007 Rotary wire brush is what i use, failing that then by hand. Quote Link to comment Share on other sites More sharing options...
Jive Posted April 9, 2007 Author Share Posted April 9, 2007 Rotary wire brush is what i use, failing that then by hand. Was that like an attachment to a drill? If so I think I'll have to go purchase one of those Quote Link to comment Share on other sites More sharing options...
JustGav Posted April 9, 2007 Share Posted April 9, 2007 You can actually buy some polishing kits off the 'net if you fancy the time and effort it takes to get a mirror finish.... Quote Link to comment Share on other sites More sharing options...
Jive Posted April 9, 2007 Author Share Posted April 9, 2007 Well for starters I just want to clean the crap off of there, if you look at the two pics you can see the dark grey bits in the areas I have done are like stuck on dirt and have tried about 4 or 5 applications to remove them. Just wanted to know the best way of getting it all off for starters, then I'll start work on the polishing ... especially now I know how to remove it all Quote Link to comment Share on other sites More sharing options...
TLicense Posted April 9, 2007 Share Posted April 9, 2007 Sandblast again. If you've not got one, take it to a local workshop and ask them to do it. Should only cost £10-£20 max. Quote Link to comment Share on other sites More sharing options...

colsoop Posted April 9, 2007 Share Posted April 9, 2007 Get it bead blasted or buy yourself a couple of scotchbrite mops to go in a drill. Get the extra fine type. Quote Link to comment Share on other sites More sharing options...
Jive Posted April 9, 2007 Author Share Posted April 9, 2007 That's great advise, thanks gents .. unfortunately I don't have a bench so looks like my Dads garage is gonna be required Will the scotchbrite mop get in all the nooks and crannies ok?

Not i wouldn't you would need to get some sheets or pads as well. If it was me i would pay for the blasting to be done (once you have masked up areas that you dont want blasting) Buying this that and the other will add up to around the same cost of getting someone to blast it fore you then of course you have to spend your own time doing the work Quote Link to comment Share on other sites More sharing options...
R3DG3CKO ROB Posted April 9, 2007 Share Posted April 9, 2007 I really want to start pollishing my engine parts - do they need to be sand blasted first then? Quote Link to comment Share on other sites More sharing options...
colsoop Posted April 9, 2007 Share Posted April 9, 2007 I really want to start pollishing my engine parts - do they need to be sand blasted first then? I wouldn't, the blasting process seems to harden the surface making it a lot harder to polish. Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted April 9, 2007 Share Posted April 9, 2007 Don't get them sand blasted, as they will corrode more easily, glass bead or another polishing type of media blasting is better, and you will need to mask up and be prepared to make sure that any residue is completely cleaned out;) i used to run a blast cleaning company, so i know what i'm on about.

Tricky-Ricky Posted April 9, 2007 Share Posted April 9, 2007 Yes i miss being able to just get parts cleaned up and refurbished, looking like new, used to be able to get some very interesting finishes, i once built a custom bike using a mix of blast finishes and polishing, have to see if i still have a pic.

Jive Posted April 9, 2007 Author Share Posted April 9, 2007 So I take it that it's better to get it glass blasted than sandblasted if you want to get it looking smoothe and shiney? Has anyone got a local company in Hampshire that they can recommend seeing as I really want to get this done this week while my car is off the road?
