Most common oil leak in a 4D56 motor

[Stewie81]

Hello all,

I have an oil leak in the front of my 4D56 motor but I can't for the life of me find the ________ thing.

What is the most common place these motors leak from?

Cheers in advance
Stewie

Id say either crank seal or cam seal Are most common.... Or of coarse the front edge of the rocker cover could be leaking..

Thanks for that. I have done the Rocker cover gasket so I think I will look into the crank and cam seals.

Cheers

crank seal, replaced mine after previous owner said he would use 2L of oil a week, no leaks what so ever now.
