I need to do an engine job for my nissan infiniti 2008. the engine is a VQ35HR. the car is consuming one quart of oil every 500 - 700 km. I was told by my mechanic that I need piston rings and bearings, gasket and seals. I want to buy these parts rather than going to a dealer. I am not sure if I have everything for the engine job on the list. can someone help me put the list together?

You may want to start reading the FSM for your vehicle prior to purchasing anything.

Should we assume that you have all the necessary tools and equipment to rebuild an engine?

Assuming you don't have any scoring of the block via pistons then the parts themselves may work out for you. If not then you may need to go oversized. In addition I would consider replacing timing tensioner and other potentially worn parts.

Is your mechanic certified for these engines? The HR motors all have specific intake and exhaust timings that are critical.

Honestly it may be cheaper overall by buying a reman'd motor with a warranty.
