Hey all,

So my car was going for a tune and tuner realizes the car was burning oil. Did a compression test and results were

Cylinder 1 - 140psi
Cylinder 2 - 140psi
Cylinder 3 - 148psi
Cylinder 4 - 165psi
Cylinder 5 - 110psi
Cylinder 6 - 75psi

Yes, they were pretty bad. What could possibly be causing the low comps (bad hg, piston rings, exhaust valves)? Will it need a rebuild?
The current car set up is a T04Z Garrett Turbo, FID1000cc, Radium Fuel Rail, Radium FPR and Twin Walbro Fuel Pumps.

*Sorry for such a noob question. I've worked on several cars here and there but still learning about the JZs.
