pdt Posted December 13, 2009 Report Share Posted December 13, 2009 I've read about black specks on the rear bumper meaning that the cars burning oil so thought i'd ask for a bit more info.I've got a 1.4 sport with 73k on the clock. It never skips a beat, runs nice and smooth, pulls well etc but i've noticed the dreaded black specs. How big are they normally cause i've got millions of the things.I washed the car today at 2pm, drove about 40 miles and once i'd stopped, the whole of the rear of the car was filthy, as in all up the boot, the window, slightly round the sides, and either side of the exhaust, not just above it. This seems a bit extreme as i've never really noticed it before and the rest of the car is still 100% clean :SOnly thing is, i have some oil running down the block, which i assume is the rocker gasket, could this be related? is it posible that it isnt the rocker gasket?Sorry for the essay, pretty worried!!Paul.

cafcross Posted December 13, 2009 Report Share Posted December 13, 2009 The dirt on the back is just that...dirt! The Lupos seem to have been designed in a way that the rear bumper chucks all the dirt up off the tyres and onto the boot and window. Mine is filthy at the back yet the sides and front look clean.

funkycooljem Posted December 13, 2009 Report Share Posted December 13, 2009 is your oil level going down? if it is droppin quite fast then its prob oil but if its not it will just be dirt. the black spots i had on mine were all small and a kind of dry texture but unlike dirt if u spayed it with water it stayed where it is, u had to rub them off. also wipe the bottom of the inside of your tail pipe, mine was really thick with soot but it was slightly sticky, hope this helps Quote Link to comment Share on other sites More sharing options...
CasperGTI Posted December 13, 2009 Report Share Posted December 13, 2009 As a sudgestion, which could prolong the issue slightly. Have you thought about flushing the engine and going to a thicker oil? say a 10w50??It might hide the problem for a while, give you time to save up for the valve stem seals to be done.John Quote Link to comment Share on other sites More sharing options...
electricpanda Posted December 13, 2009 Report Share Posted December 13, 2009 I thought it was just tar or something from driving down a new laid road. Mine has then over the boot and window from last week. I'm hoping they'll come off with some remover.. Quote Link to comment Share on other sites More sharing options...
hunid-brake Posted December 14, 2009 Report Share Posted December 14, 2009 hasnt this been reported with sports before?? something to do with knackered piston rings? Quote Link to comment Share on other sites More sharing options...
funkycooljem Posted December 14, 2009 Report Share Posted December 14, 2009 yeah it has lol! i was well unlucky i think though coz mine was warped pistons and cylinders. a new bottom end and refurbed top end and its all fixed now Quote Link to comment Share on other sites More sharing options...

marcusgrant Posted December 14, 2009 Report Share Posted December 14, 2009 No way! I'm sure people have had these specks before and then they just go... Quote Link to comment Share on other sites More sharing options...
TomStevo Posted December 14, 2009 Report Share Posted December 14, 2009 could just be tar spots, mine has tar spots all over it, really need to tar remove and clay mine to get em off, if you just have em on back tho cant see it been tar spots, they are usually just down sides of car Quote Link to comment Share on other sites More sharing options...
electricpanda Posted December 14, 2009 Report Share Posted December 14, 2009 I'm worried now, I'm sick to death of spending money on this car. Might just p/x it in for something more reliable!.. Quote Link to comment Share on other sites More sharing options...
pdt Posted December 14, 2009 Author Report Share Posted December 14, 2009 Thanks for the replies people!I washed my car again yesterday and yet again, covered in specks already. I'm hoping its just crap off the roads as theyve all been gritted and i run wide wheels which flick more dirt up. Really can't be bothered with refurbing the engine!As the guy above said, p/xing it is sounding better and better! Quote Link to comment Share on other sites More sharing options...

jamiea7x Posted December 14, 2009 Report Share Posted December 14, 2009 i gte the black specks on mine and i slightly burn oil, but the car runs fine and has done afor a good few thousand miles like this so im just not thinking about it anymore, just keep a closer eye on oil levels tho, ill start to worry about it when it starts not running properly Quote Link to comment Share on other sites More sharing options...
electricpanda Posted December 14, 2009 Report Share Posted December 14, 2009 Im gonna check the oil when I get to the car park after work. See how it is.Cheers people. Quote Link to comment Share on other sites More sharing options...
hunid-brake Posted December 14, 2009 Report Share Posted December 14, 2009 yeah again im sure there was a topic on this before. I dont think anyone actually suffered any lack in performance or reliability issues i think its just worn piston rings that are leaking oil through and subsequently burning it off and out of the exhaust. If you can live with it it should be fine. Like said above just keep an eye on levels and stuff like that. Quote Link to comment Share on other sites More sharing options...
pdt Posted December 14, 2009 Author Report Share Posted December 14, 2009 Just compared my car to my mates 59 plate fiesta and his is covered in the exact same crap as mine, so it must be the road! Also a good way to check, as he pointed out, is rub your finger inside the exhaust tip, if its covered in oil, bad news, if you just get soot, good news! Hope that helps people.Im off for a celebratory beer Quote Link to comment Share on other sites More sharing options...
99hjhm Posted December 14, 2009 Report Share Posted December 14, 2009 Are you guys sure it's not just abit of water?? If I start mine up with the back up against the garage door, it plasters it with black specs, old cars are dreaful for it.My cars black, so I can't really see any specs, and it doesn't burn any oil.

funkycooljem Posted December 14, 2009 Report Share Posted December 14, 2009 well mine had sticky stuff in the exhaust but it wasnt really gooey or anything just like normal soot but excessive ammounts and it was slightly tacky when u rubbed it between your fingers. i also didnt have any performance issues but it did get to the stage where i had to fill up with oil every time i filled up with fuel! all in all for a brand new bottom end from vw, have my head refurbed, new cambelt, service etc, labour and vat it came to just shy of £1600.

Just keep an eye on it, bacause you will go over on unburnt hyrdocarbons if it gets too much, which will fail.Have you switched to a thicker oil? That will help you burn less.John Quote Link to comment Share on other sites More sharing options...
Niche Posted December 15, 2009 Report Share Posted December 15, 2009 I had this on my Sport, though in my case it was throwing out tiny chunks of black dirt.The standard backbox has a section which stores dirty oil which has passed through the exhaust system, perhaps this section is simply full and dirty oil is being passed through this section and out the back.After 4 oil changes with Quantum Gold and an engine cleaner (once) in 10k miles and a new stainless steel backbox which doesn't have this stupid oil section, all was fine. The only build up after that was just light black dusting on the tip which built up a little bit after two weeks. My Sport does use oil but thinking about it logically they designed the backbox like that knowing these engines pass through oil. It does say in the book that they can consume up to a litre of oil per 1,000km or something silly like that depending on how you drive the car.Nothing to worry about.
