2005 Chevrolet Lumina Engine oil leakage

what engine?

Dear Hmac My cars engine is V6.
I feel the box from which the engine oil is leak is called (engine oil pan).
There is a leak of engine oil from that pan.
I hope my problem is clear to you now.
Any advise?
Thanks

there is a gasket that may be leaking or a seal at front of timing cover. the engine has to be put in a ling in order to get the pan off. and gasket replaced. if it's a large oil leak like dripping constantly then the engine will need cleaning because it could be coming from another area and all you see is leakage at bottom.

Dear Hmac,

Thank you very much for your expert advise. Its really helpful.
I have attached highlighted image with circle were i have observed the leakage.
Should i replace this part or it can be fixed with epoxy or something?

it's aluminum so you would need a product that will bond to aluminum and also a spray cleaner like brake clean to get the oil off otherwise it won't stick. however if you spray it and it gets oily right away this was damage done by hitting a curb block or something similar and the only thingwold be to replace it.

Thanks for your help and expert advise i will replace this part as you have suggested tomorrow.
