1. Motor Oil <Synthetic>
2. Oil Filter
3. Cam seals (4 count)
4. Valve cover gaskets
5. Intake gasket set
6. Timing chain tentioner
7. Pcv valve
8. Coolant
9. Valve stem seals <HP Silicone> (24 count)
10. BG induction system cleaner treatment
11. Front Crank seal

 

Nope

 

I'am no mech. but its an upper engine fix.............full engine re-build should be around 6.5k.

 

Wow, that's hefty. I'm getting a few estimates. I'll let you know what comes out of it.

 

I have the same OC issue and I have been measuring it overtime and so far I have put 2.5 at over 3500miles. I am thinking about have the cylinder honed and bored a tiny bit so I'm not too far off from stock. Idk exactly how to go about this. I have 94k mi and I use Lucas synthetic additive and I mix 1qt with 4qt mobile full synthetic 10w30 hi mileage. Any advice will help. I am literally flying through plugs and oil.

 

So I just rolled over 4k miles and I have topped the oil off with 4qts. I'm changing my oil tomorrow. Any suggestions to fix this?

 

Nope! I had an complete engine rebuild, one of the cylinders was oval, car still sucks oil!
