VR6Rich 3 Posted June 25, 2004 Report Share Posted June 25, 2004 Does anybody know how to get the front plastic spark leads guide off of the intake manifold? Fancy doing some polishing today but want the manifold bare so I can polish it all over. :-)Also, anybody got any tips on the best way of polishing the manifold?Cheers Link to post Share on other sites
nickbee 1 Posted June 25, 2004 Report Share Posted June 25, 2004 The plastic lead guides slide about 1cm to either the right or left and then just come off - they're held on with 'L' shape legs.Start polishing with 40 grit, then work your way down to 60, 120 etc all the way down to 1200 or 1500 wet and dry (which is best used wet).jcorallo always warms me about the dangers of getting all the aluminium dust all over your engine, but I ignore him...

VR6Rich 3 Posted June 25, 2004 Author Report Share Posted June 25, 2004 Its ok, ive got a seperate manifold to polish anyway so the aluminium dust wont be a problem. :-)So is it best to use all grades dry until you get to 1200/1500?Cheers Link to post Share on other sites

VRmonster 1 Posted June 25, 2004 Report Share Posted June 25, 2004 what do you use to wet it, wd40 or water or a special oil? never really thought about it. lol. Link to post Share on other sites
binliner 0 Posted June 25, 2004 Report Share Posted June 25, 2004 lol just water with a squirt of washing up liquid Link to post Share on other sites
VRmonster 1 Posted June 25, 2004 Report Share Posted June 25, 2004 cool, thats easier. my mate told me to use wd40 to make it easier to sand, i thought it was a chew on so didnt bother. mite give this a go with some spare time this weekend. Link to post Share on other sites
madmonkee 0 Posted June 25, 2004 Report Share Posted June 25, 2004 dont bother! ive been polishing my schrick since we all got them! Link to post Share on other sites
nickbee 1 Posted June 25, 2004 Report Share Posted June 25, 2004 Yeah, it takes a while... Link to post Share on other sites
acf8181 0 Posted June 25, 2004 Report Share Posted June 25, 2004 get it chromed instead! Link to post Share on other sites
binliner 0 Posted June 25, 2004 Report Share Posted June 25, 2004 you'd still need to polish it to get rid of the textured finish Link to post Share on other sites
FishWick 21 Posted June 25, 2004 Report Share Posted June 25, 2004 To get the front cable guide off, slide it to the right. The other guides come off by using an 8mm spline too. Link to post Share on other sites
VRmonster 1 Posted June 25, 2004 Report Share Posted June 25, 2004 you cant chrome them, theyre cast aluminium arent they? thought u could only polish em to a chrome look finish. not actally have them chromium plated. im thinking about a kit that goes in a drill, wil surely spruce up the engine bay in a much quicker time, lol.

FishWick 21 Posted June 26, 2004 Report Share Posted June 26, 2004 You can chrome pretty much anything if the preparation is right. The plastic VR6 badges are chromed for instance. I personally don't like polished manifolds and it effectively reduces the heat dissipation qualitys of the casting. Link to post Share on other sites
mina 0 Posted June 26, 2004 Report Share Posted June 26, 2004 Good point there Kev - never thought of that. Guess the original finish acts a bit like a heatsink? Link to post Share on other sites
FishWick 21 Posted June 26, 2004 Report Share Posted June 26, 2004 Yep..... standard manifold = /\/\/\/\/\/\/\//\ and polished is _____________. Guess which acts as a better heatsink? VR6s are a very hot running engine, especially the rear bank of 3, so heat dissipation is a primary concern. Corrado and Golf VRs should have come with bonnet vents imo but they're untidy and boy racerish. You also have to be careful with internal polishing to avoid wetspots. Flowing air moves faster over air trapped in factory casting imperfections than it does over a polished surface.I know this all sounds very anal and delving too deeply into volumetric air flow turbulance technology but it does make a difference.[ Edited Sat Jun 26 2004, 11:43PM ] Link to post Share on other sites
acf8181 0 Posted June 27, 2004 Report Share Posted June 27, 2004 very ture kev...and anyone who's ever been within about 5 metres of a vr6 after its been blasted will know they are hot cars. Link to post Share on other sites

Eat this 2 Posted June 27, 2004 Report Share Posted June 27, 2004 yup when i get out i can feel the heat driftin out the back of the bay past the doors its even hotter air when the fans on Link to post Share on other sites
