Found a few surprises!!

M88JCP · Oct 1st, 2020, 22:12

Evening all

I hope your all keeping safe?

Well, I managed to get under my C30 T5 for the first time today and was greeted with a few surprises. The first being an unplugged wire connector hanging down in front of the oil sump and the second being a oil leak from above the dip stick tube.

Can anybody help with some questions?

- What is this connector and should i be worried about it being unplugged? The wires are green/ cream and black/ cream in colour. I've checked all around the engine and cant find anything to plug it into.

- Is there a known spot for oil to leak from the front of the engine, around the vicinity of the oil dip stick? I know that it might sound stupid asking about the source of an oil leak around an oil outlet but the oil appears to be leaking above the tube from higher up the engine.

Thanks
James

I would check your oil filter housing hasnt leaked, these are common issues on these engines.

Thanks Dom, I know it sounded like a daft question, but starting the search with known 'weak' spots might help me diagnose the problem quicker

There are (was) known issues with the oil filter housing but only on the 'air side' - the breather side. They never actually leaked oil.

These engines are not known to leak oil to be fair, it is possible I guess that whoever did the last oil change was messy with it and spilt it all around that area.

The cable underneath, not to sure. When did you by the car? could possibly be a 02 sensor unplugged? does the car have a cat on it or decatted?
