| Post subject: | oil leak |
i have a bit of a problem i have had my motor rebuilt and put together by a really well known mini place in adelaide it hasnt even done 800 miles yet its got 15?w-40 oil in it and it leaks like a siv i checked some of the bolts on the timing cover and i reckon you could almost undo them by hand have they come lose or were they not done up tight enough in the first place?? just wondering if i put 20w - 50 oil in it and do all the bolts up tighter will this stop the problem? |

The small timing cover bolts are only 6 ft/lb, the bigger ones are 15 ft/lb. Don't overdo them or you can bend the cover's flange around the holes. |

The diff side covers should be 18ft/lb. I would drive back to the `Mini shop' and have a whinge... 20W/50 won't leak less. Unless it has 15W/40 synthetic in it (surely not, in a rebuild) then maybe. No need for a catch can unless you are racing. |

If it leaks oil, then it leaks oil,,, changing oils won`t stop it leaking, it will just change what oil leaks out probably needs to have the gaskets & sur4faces around the leaking area(s) fixed/repaired/replaced & possibly the use of some gasket goo may be needed too |

well my guess is you went to the same bloody place I got mine done. The cheap so and so's didn't put a gasket in the entire thing. My diff side covers leak and they stripped some threads too...... S pose they were about $500 cheaper than most places.. cant really windge.. I also found out later that these rebuilt boxes don't like much power either. PM if you wanna know if we are talking about the same person.. |

. That's a sure sign of a cheap re-build. A proper job will cost $1500 at least. Small bikkies really. Lots of horror stories out there even with late model cars, so don't complain. |

While there really is no excuse for a reco jub that leaks oil, be aware that some of the late diff caps do not use gaskets. There is no tell tale to say if you need to or not, only to put the cap on without gasket or diff and measure the bearing tunnel twice at 90 degrees to check if it is round or out of round by about 7-10 thou. Yes, all the diff side covers (were it appears you guys are having leaks) do use gaskets. |

That is #1 leak spot on a rodchange box. You can do it in the car after you disconnect the shifter rod. Method 1: pry the old one out, knock a new one in. Method 2: put a new one against the old and knock them both in. There is room for 3 in there altogether... 
There is also an aftermarket anti-leak kit (spacer + O-ring etc) available, I've never found the need for one so dunno if they are any good. |
