Oil leak nearside of engine
Hi all, have noticed nearside of engine is covered in oil. Am thinking two things, oil seals on vacuum pump or oil filter housing gasket. If vacuum pump is it inlet manifold off.
Any info much appreciated as always

On a 2003 2.2 M54 on the nearside it's almost certainly the o.f.h gasket. At possibly 20 years old it will have turned hard and brittle leaking oil down the side of the block. Shine a torch in the gap between the oil filter cap and block and you will probably be able to see the source. When you say vacuum pump do you mean the C.C.V ? If original it also will have become brittle and well past its best. It can all be replaced without removing the inlet manifold but much easier with the manifold removed as I did

If you clean it all off and see where it starts to re-appear you might be able to work out which of those it is.
Coupes because stunning!

Thanks for info, don't these engines have a vacuum pump for the brakes that have two oil seals?. My CCV is ok I did the test of taking oil filler cap while engine running and not much vacuum there.

Bit of a novice on these cars but learning. Just seen a video on o f h and yes I would definitely say you are right my leak is coming from there.

Very common. Not a difficult job but the o.f.h is also part of the alternator mounting bracket so you have to remove the alternator and belt as part of the job

If you decide to do this job, plenty of videos to show how, watch the tops of the wings as you will be leaning over them quite a bit. Either wear an overhaul that button on the inside or buy a wing protector mat.

To add to what Raymond says, if doing any prolonged engine bay work I always make sure the car is clean so you're not going to rub any grit into the paintwork. I usually wear an old sweatshirt and tracky bottoms, no zips or fasteners. However, the best tip I have is to raise the front of the car up on axle stands or ramps. It saves a lot of stretching and straining and leaning over against the wings. Your back will thank you for it too Also with the car raised it's a 2 min job to remove the undertray for extra access from below if requiredmattimus wrote: βTue Mar 21, 2023 8:37 amWhat a cracking tip to save a load of unnecessary stressraymond.harper wrote: βTue Mar 21, 2023 7:35 am If you decide to do this job, plenty of videos to show how, watch the tops of the wings as you will be leaning over them quite a bit.

Good luck. This is a video of the 2.5 but there are many similarities with the 2.2 Ignore the middle section. https://www.youtube.com/watch?v=I95LurFYbtg&t=729s
