I got 3.4 V6 that leaks engine oil. Already change the rear main seal , Valve cover gasket and oil pan gasket . Anybody got idea where could the engine oil leak possibly came from? Please help

 

wheres it coming from? front or back of motor. need to try and follow the oil trail. i believe theres a oil pressure sending at the backside of the intake. could be leaking. what yr?

 

comming from back of the motor , seems impossible to follow the oil trail because it only leaks when engine is on , 1995 is the year of the car , other than oil pressure sending that could be cause , any other idea where it could be ? thansks

 

Intake manifold gasket?

 

i agree with heathen, i thought u said u replaced the intake so i didnt mention it. the end seal on the intake is probly what it is.

 

My wrenchin buddy just found that on my 96Z. Nasty damn mess and I couldn't find it.

 

i would go with oil sending unit also

 

or a clogged/cracked egr/ egr lines

 

Im new to this but does normally Intake manifold got oil on it? as to my understanding ( im not a mechanic ) it gives air or allows air to get in the engine. Please correct me if im wrong if i got the wrong theory about it.

 

If i don't have oil pressure drop on my gauge , would it still be the oil sending unit? oil sending unit is located at the oil pan right? if so i don't see any leak from it. Thanks
