Mark Piper Posted February 18, 2002 Share Posted February 18, 2002 What does this mean? no trace of water in the oil....nor overheating...oil pressure's at 4.....I'm rather hoping it's mothing more sinister than just....green sludge in the header tank... Yours hopefully..... Link to comment Share on other sites More sharing options...
Blatman Posted February 18, 2002 Share Posted February 18, 2002 If it's very dark green, it sounds suspiciously like radweld......... Link to comment Share on other sites More sharing options...
Mark Piper Posted February 18, 2002 Author Share Posted February 18, 2002 Blatters - it's more a kind of pea green...remarkably similar to the colour of your car as it happens....wink.gif Link to comment Share on other sites More sharing options...
Blatman Posted February 18, 2002 Share Posted February 18, 2002 You haven't sucked up the remnants of the plastic I left at London to Brighton have youquestion.gifteeth.gif Pea greenid=limegreen> sludge ehquestion.gif I occasionally get green residue on my shower tray at home. It's from the copper pipes (apparently), but it's just a discolouration, rather than sludge. Do you have a copper rad, or an ally onequestion.gif Could it be radweld mixed with bright green coolantquestion.gif Edited by - Blatman on 18 Feb 2002 10:39:07 Link to comment Share on other sites More sharing options...
Mark Piper Posted February 18, 2002 Author Share Posted February 18, 2002 I knew you couldn't resist a response....thumbsup.gif I agree it could be radweld - what miffs me is that Hyperion fitted a "perfect" secondhand high capacity rad (and it's no alloy, so by definition has to be copper, I guess) to my car last year....so why would they have felt it necessary to introduce radweld?....it reassures me that you haven't mentioned head gasket failure....nor has anyone else...yet Link to comment Share on other sites More sharing options...
Blatman Posted February 18, 2002 Share Posted February 18, 2002 Bite Bite Bite Bite etcteeth.gifteeth.gif Yeah, I had a similar experience with my XR4x4 tow car. Supposedly good second hand rad, but dark green sludge in the header tank around the filler necksad.gif Head gasket failure would see a mayonnaise type sludge in catch tanks, and around the oil filler cap too, as well as your coolant turning a horrible brown colour. Should've asked before, what enginequestion.gif Link to comment Share on other sites More sharing options...
Mark Piper Posted February 18, 2002 Author Share Posted February 18, 2002 K series - what else?....wink.gif I'd better check the coolant isn't a horrible brown colour (but I already know it's not) but I do wonder if it were head gasket failure whether synthetic oils do give the coolant water a different colour to the good old mineral oils of old...
