Driving after valve adjustment

[dtsol]

I just had a valve adjustment on my very new to me 911. It's my first 911 and my first valve adjustment.

My question is: is there any special care that should be taken after a valve adjustment in how you drive the car (i.e. keep revs below ______, don't do hard acceleration, etc.)? Anything I should know about how to treat the car right?

No. Have at it. John.

911’s don’t like to be babied... Drive it like you stole it.

One of the beauties of these cars is that they are made to be driven. Aside from the important warm-up period (take it easy until the engine is up to normal operating temperature), let ‘er rip.

Cool, thanks!

And note - Lyle's comment about warm-up doesn't say let the car IDLE until warm-up. Start the car and get moving - just keep the RPMs below around 4k until the engine is warmed up.

Question?

Can a loose or very noisy valve train cause blue smoke out the exhaust?

I think the official spec is to avoid sustained driving above 5000 rpms until the engine is warmed up. Pretty impressive. Also, specs allow for significant oil consumption before rebuild is necessary. These engines are amazing.

The biggest issue with above 4,000 RPM and cold oil is excessive oil pressure. The bypass valve can't flow the thick oil enough, and the seals tend to get oil pushed out, and leaks develop.

So keep it below 4K until the oil is at least 180 degrees.

After that, let er rip. Mine sees 6K regularly. One of the new members that joined or local PCA region bought a really nice 87 911. He was saying he never goes above 4,500 RPM. I told him that is nuts. The engine is designed to run at 6 grand all day long as long. I took him for a ride in my 85 and since it was summer it warmed up fast. Then I made a few runs through 1st and second and into third and showed him the real fun of the torque band start at 4,000. Several members urged him to run it harder than he had. A few years later he told me he finally took my advice and was astonished at the enjoyment of the higher RPMs.

3.2 come alive above 4k

Poor guys is missing the reason you own a 3.2
