Hi, there is a common leak that comes from the expansion plate at the front of the motor.
If you have a leak at the left front of the motor I would suspect a leak from the expansion plate.
The plate is located just below the oil filter housing on the front timing cover.
is a new seal needed for the repair?
Yes, click on the image above.
The rubber seal behind that plate can fail and create a good size oil leak.
Got it, can this cause the leak to get larger over tim?
Yes, as the rubber seal hardens it can become a pretty large leak. You can also get leakage from the front crankshaft seal and the valve covers but the seal at the plate is a pretty common problem.
OK, I think I got it, I have replaced the cover gaskets and the oil filer housing
Thank you Eurotec you were a great help.
It's just below the filter housing
You're quite welcome
Have a great weekend
