top ten most probable sources of a oil leak !!!
« on: 29 June 2007, 18:06:48 »
My way of trying to find the leak on my 2.5 v6 ! ;D

I'll start !!

Cam covers ( changed and checked)
Oil filter ( changed and checked)
Drain plug ( checked )


Ive spilt a large box and put it under the engine, so fingers crossed it will give some clue.

Get some gunk or jizer or traffic film remover(used strong), jack the car up then spray all around under engine etc etc, work it in with a washing-up brush then hose off using a strong jet. Once it is dry you should be able to localise the leak.

right !

cleaned all the sh1t from the bottom of the engine, left it running for 15 mins, will check tomorrow for any evidence !
Did notice the that there was an oval hole that looks like it should have a plug, looks like part of the transmission.
the hole is approx 2 inch wide by 3 inch high. its near the x member at the rear middle of the engine.

Though the hole you can see what looks like a metal disc. I'll see it i can get a pic
