mat h Posted July 19, 2001 Share Posted July 19, 2001 Right now is the time to shine guys! I am a complete numpty when it comes to engines and stuff so I am hoping you clever 7 chaps may be able to shed some light on a tricky situation. I have a 1600 K series with a six speed box, every now and then when I drive it real hard I end up with a puddle of what would seem to be some form of transmission oil on the garage floor directly under the seats! I took my baby to Arrow Star and they couldn't find any leakage what so ever. Presuming that it may have been a one off I drove it again and noticed an even bigger puddle when I got the car out to check it tonight. You can't see it dripping, and just as sod intended it when you go to the specialists she decides to behave! Any ideas on what it could be or should I be jumping on Caterham as the car is only just out of waranty? Thanks a million for any advice! Numpty Mat.

John Whyman Posted July 19, 2001 Share Posted July 19, 2001 Don't forget that your seat is virtually over the back axle, have you had a good look at the diff and surrounding areas? Happy Motoring. thumbsup.gif C7 WJW. Link to comment Share on other sites More sharing options...
I reply to every thread Posted July 20, 2001 Share Posted July 20, 2001 What does it taste like? Seriously - you must be able to collect some and find out what it is. Gear oil, Diff or engine. That would be a start. Link to comment Share on other sites More sharing options...
Tony Martyr Posted July 20, 2001 Share Posted July 20, 2001 I would suspect 6 speed box pressurising when hot and leaking through the speedo drive. Oil will be red if this is the case but it will also have splattered down the prop shaft and onto the rear A frame etc. Link to comment Share on other sites More sharing options...
kenny. Posted July 20, 2001 Share Posted July 20, 2001 I bet it's the main oil seal on diff.......I fitted a suretrack 18 months ago, and found it had a gravity leak (i.e. puddle on garage floor after 36 hours)...took the bugger out out again and put a new seal in after checking surfaces.....still leaked. Did it one more time.......still leaks. Decided to leave it now as leak has slowed a lot as oil level is now probably to bottom of seal...(hope that's enough oil for safety) It never seems to leak when on the move..just when car is laid up.

EFA Posted July 20, 2001 Share Posted July 20, 2001 There is a breather nippple on top of the 6 speed box. Connect this to your catch tank and all might be fine. The breather nipple is on the top of the tailhousing.

CHRIS CLARK Posted July 20, 2001 Share Posted July 20, 2001 All this talk about a 'World of Pain' and Arnie going on about 'breather nipples' had me thinking I was on the wrong site!!! Link to comment Share on other sites More sharing options...
mat h Posted July 22, 2001 Author Share Posted July 22, 2001 Thanks for all the responses guys, the oily stuff (once again Mat shows his motor skills off to their full potential) is a darkish yellow and quite thick. I have driven the car today and the gear box seems fine, as far as I can tell there is no signs of any problems - yet to see how much leaks overnight though!

John Whyman Posted July 22, 2001 Share Posted July 22, 2001 Are you sure the 'oily stuff' isn't grease from the Universal joint on the end of the drive shaft where it connects to the diff?? Happy Motoring. thumbsup.gif C7 WJW. Link to comment Share on other sites More sharing options...
EFA Posted July 22, 2001 Share Posted July 22, 2001 Sounds like gearbox oil.... Check your nipple!
