Mercedes-Benz E320 4Matic: Have oil leak left front of my 99

This answer was rated:

Have oil leak left front of my 99 E320, It not to bad yet the last time I repair one was in the mid 80's it was the seal behund the power steering pump, I hopre it's not that.

eurotec :

Hi, there is a common leak that comes from the expansion plate at the front of the motor.

eurotec :

If you have a leak at the left front of the motor I would suspect a leak from the expansion plate.

eurotec :

The plate is located just below the oil filter housing on the front timing cover.

Customer:

is a new seal needed for the repair?

eurotec :

Full Size Image

eurotec :

Yes, click on the image above.

eurotec :

The rubber seal behind that plate can fail and create a good size oil leak.

Customer:

Got it, can this cause the leak to get larger over tim?

eurotec :

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.

Customer:

OK, I think I got it, I have replaced the cover gaskets and the oil filer housing

eurotec :

Ok

Customer:

Thank you Eurotec you were a great help.

eurotec :

It's just below the filter housing

eurotec :

You're quite welcome

Customer:

Have a great weekend

eurotec :

Thank You!
