Oil Consumption 3.2 as PSA?

[shawn908]

Oil consumption is the prostatic hypertrophy of my 3.2. It’s not a matter of if, or when. It’s how much will it affect me. Will I be able to live with it. On the one hand manage the sidelong glances – olfactory-driven glances of those too young to know, who followed me, and who have not owned their 3.2 long enough to fully accept that this will happen to their 3.2 as well. I’ve not read on Pelican anything that contradicts that if you own – and drive – any 3.2 long and hard enough, oil consumption will increase.

Burning oil is intrinsic to the glory of everything the 3.2 gives us; those hard rips through twisty ascending roads, high RPM drives when it’s not below 4000 and peaking at 6300. There is a cost: consumption of oil. I’ve probed the 3.2, reluctantly or accidently when I changed to M&K RSR headers I saw discolorations on the exhaust ports and valves, accumulations. I know what my 3.2 is telling me. But instead I think don’t worry it’s going to be OK and this happens to all 3.2’s, we can’t control the impact of time and use, run it until, until blue smoke billows. Then I will see my mechanic and lie and say I never noticed anything it just started blowing blue smoke what can we do to save my 3.2? There will be options. Possibly too far gone for a local solution. Then I will think should have admitted there was a problem and fixed it early.

We have all heard the old adage, men die with prostate cancer or from it. No avoiding it. I had my last colonoscopy partly to avoid the old digital probing from my doctor. Everything came out fine!

My 911 3.2 was at 150,000 miles and it was using about a quart every 800 miles the way I drove it (hard) and I had a head become wet. Drop the engine, pull the head and sure enough two studs had become loose. They did not break or pull out, they just somehow backed out. So with the heads off, and a top end for sure to be done. might as well slide the cylinders off and take a look and maybe change the rod bolts. But while we are in there, and while we are in there......

Full rebuild later I get 1,600 to 2,000 miles on a quart. The old valve guides were certainly worn. All new ARP rod bolts, case bolts, and 964 cams and all is well. I just returned from a 800 mile journey to Arkansas driving the best road in the USA, and I used just under 1/2 a quart, and turned 187,000 miles on the way home.

Why do 3.2's do this?

The piston and bore diameter is the same as a SC and SC's don't go through oil like this. If it's the valve stem seal they can be replaced and it should stop.
