TaffyTim 6 Posted April 22, 2007 I went for a track day on monday and was out for 2 sessions and had to finish a session early as i was leaving alot of oil behind me. Today i spent a couple of hours under the car cleaning all the old oil off and have taken it for a hard drive to get it leaking again so i can see where it might come from. I originally thought that it was engine oil and not gearbox oil but im not so sure today as it smells slightly petrol like. If anyone can suggest where its coming from that would be great. 1 Here is the amount of oil dropping off different parts of the car after sitting for a few mins, 2 When you first look at the engine bay you can see the main spray is on the bulkhead behind the gearbox, the engine side of the bulkhead is quite oil free: 3 looking down the back of the gearbox you can see a large pool of oil in the gearbox casting(in the centre far left) and a good colection on the end of the cracked cable, what is this cable?(centre) http://img.photobucket.com/albums/v645/taf.../oilleak003.jpg 4 coming forward on the engine you can see the same pools again http://img.photobucket.com/albums/v645/taf.../oilleak004.jpg 5 coming further around you can see more spraying in the castings(bottom left quarter) http://img.photobucket.com/albums/v645/taf.../oilleak005.jpg 6 from under the box you can see 2 oil tracks http://img.photobucket.com/albums/v645/taf.../oilleak006.jpg 7 Looking up at the AFM, there are a number of different wet points http://img.photobucket.com/albums/v645/taf.../oilleak007.jpg 8 looking a bit to the right http://img.photobucket.com/albums/v645/taf.../oilleak008.jpg 9 The inlet mainfold has oil marks which had been cleaned off earlier, and also down the oil breather pipe there was some fresh oil. http://img.photobucket.com/albums/v645/taf.../oilleak009.jpg 10 Oil has made its way down to the oil sump, its a shame its on the wrong side of where its supposed to be! http://img.photobucket.com/albums/v645/taf.../oilleak010.jpg Share this post Link to post Share on other sites
luggy 13 Posted April 22, 2007 Is there any oil above the head gasket on the engine?. Is the clutch slipping at all?, looking at pic 6 possibly crank seal gone due to crankcase overpressure? Share this post Link to post Share on other sites
TaffyTim 6 Posted April 22, 2007 The clutch was replaced last sunday and is working well. The most oil that i saw by the head gasket was on pic 3, in the top left corner. Other than that i didnt notice any spray above it. Share this post Link to post Share on other sites
steve@cornwall 100 Posted April 22, 2007 The clutch was replaced last sunday and is working well. The most oil that i saw by the head gasket was on pic 3, in the top left corner. Other than that i didnt notice any spray above it. Maybe the daftest question of the day-- but is it engine oil, or has the gearbox been overfilled after clutch replacement, then been flung around by the driveshaft (poss. from the driveshaft seal?)

luggy 13 Posted April 22, 2007 (edited) If you know that it is engine oil check out Pug 101's respone on this thread. http://forum.205gtidrivers.com/index.php?s...c=60914&hl= Edited April 22, 2007 by luggy Share this post Link to post Share on other sites
TaffyTim 6 Posted April 23, 2007 im going to say that its Engine oil. Its the same colour as the engine oil that is on the dipstick and doesnt smell bad enough to be gearboxoil. could the petrol like smell of the oil come from blow-by? ie petrol blowing by a piston and mixing with the oil?

welshpug 1,627 Posted April 23, 2007 cable in pic 3 is the speedo cable, look suspiciously like gear oil if its on that area and you dont have a dizzy. Share this post Link to post Share on other sites
TaffyTim 6 Posted April 23, 2007 (edited) Ta for pointing out the speedo cable. There is a dizzy but that is totally oil free. Edited April 23, 2007 by TaffyTim Share this post Link to post Share on other sites
Miles 331 1 Cars Posted April 23, 2007 Odd thing is before the clutch plate broke up every thing was dry as a bone, It's only the track day and high rev's which could be blow by in the crankcase, I'll hopefully see the car and have a better look Share this post Link to post Share on other sites
TaffyTim 6 Posted April 25, 2007 (edited) The leaking oil has calmed down a hell of a lot, but im thinking that its because the gearbox is running out of oil! When I was driving the car home today there was a loud ticking/knocking noise coming from the engine bay. When I jacked the car up and turned the wheels, i traced the noise and first of all thought it was coming from the driveshafts but then it went beak to the clutch area. The noise sounds very metal on metal like when a wheel is being turned. Is this a noise assosiated with an emptyish gearbox? ps I now know how to check the gearbox oil level but its dark and i dont have a garage, so i will check tomorrow after cycling to work Edited April 25, 2007 by TaffyTim Share this post Link to post Share on other sites
