Default Oil Leak

Hi Guys.
2003 75 CDT auto.
As a newbie I have a lot to learn , but so far this forum has been invaluable.
While fitting tyre guards to the coils today, I noticed the under tray
had been poorly re fitted by someone, so decided to take it off for repairs / refitting.
Then noticed oil leak sludge on the front nearside area of the tray. On further inspection the underside of the air intake tube , metal further towards the nearside, and even wiring running towards the headlights are covered in oil.
Could this be from the intake ? cracked ?
I am planning to clean the EGR ( and eventually inlet manifold and PCV) but would appreciate some input /pointers.
I have to add when I bough this the engine oil level was overfilled by about 3/4 of a litre which I ''sucked'' out.
Any help would be great.
Thanks
Ritz

Sounds like you have a leaking joint where the pipe fits into the top of the intercooler. Quite common, just fit it with viton oil seals and it will be fine.

Yes it will be the intercooler O-rings that need replacing, use Viton only, and remove the bumper to do a proper job, even though they can be changed from above.

And don’t forget to replace your pcv filter, this often gets overlooked.

Bumper off.

Do not try and remove the bib screws on the lower edge of the bumper, leave them on and remove the 4 under tray screws instead.

9 cross head screws across the top of the slam panel.

2 ten mm screws in the leading edge of the wheel arch.

2 self tappers on the return edge of the wheel arch liner.

4 1/4 turn fixings on the under tray.

6 self tappers on the two triangular brake ducts


Then--a sharp tug on each side of the wings to unclip the bumper from the wing.

A bit of help to move the bumper forward to unplug the light loom from the nearside chassis leg.

If fitted unclip the washer hose on the off side.




Don't be put off of it seems to be a lot of work. The bumper should be off and on the floor in about 15 to 20 minutes.
