Looking at a certain 996 locally but have done TONS of research into what ownership means.

I've known for years (just as any self respecting car guy should) that the bulk of your engine wear occurs at startup. That's why my current project car is getting a pre oiling system.

In the case of the 996, I'd like to install one as a guard against wear for all of the obvious reason. Has anyone done this on a 996? If yes, anything I should be aware of?

Thanx!

 

Given that the newest 996 you'll buy will be more than 10 years old, I'm not sure how much benefit a pre-oiling system will give you. Most of the start-up damage (if any) will already have occurred. I'd be more concerned about the IMS issues that have historically plagued the 996 engine. Good luck.

 

I'm worried about the IMS, but cold start wear doesn't stop being an issue on old cars.

 

If one lets the engine sit a long time between engine starts wear at start up is possible. (The acids in the oil causes "wear" too.)

But I dare say your info is wrong in usage that doesn't involve long times between engine starts. Given a engine like the 996 (or any modern engine) and with the proper oil and reasonably regular use there is no appreciable wear at cold start (or really at any other time).

(This is how my 2002 Boxster's engine with over 310K+ miles on it is still running just fine with uncountable number of cold starts. And ditto my 2003 Turbo with over 154K miles. I can list a few other high mileage examples with a similar lack of engine wear.)

A pre-startup oiling system is a solution looking for a problem.

However, if you want to install a pre-startup oiling system then best of luck.

At least one thing I would be aware of is with the addition of any thing else to the engine's oil system the risk of a component failure increases and the concern would be would a failure of this pre-oiler in anyway result in depriving the engine of oil -- and not just the pre start oil -- at engine start or at any time while running?

IOWs, the engine's oiling system is about as basic and simple and reliable and trouble free as it could be. Thus any modification of this oiling system could in some way affect reliability and the system may not be as trouble free as it would have been otherwise.

 

Many track cars have something like this which can be setup as a pre-oiler plus helps to maintain pressure while running.:

"If the oil in your engine sloshes away from the sump pickup under cornering, acceleration, or braking, the pump will stop feeding pressurized oil to the bearings. Even momentary losses of oil pressure can quickly damage an engine.

An Accusump is a hydraulic pressure accumulator that protects your engine from temporary oil pressure loss. The precision-machined cylinder is divided into an oil chamber and a pressurized air chamber, with a free-sliding piston between. When the oil system builds pressure, oil is pushed into the cylinder, moving the piston and compressing the air. The air acts as a spring, pushing back against the piston and keeping the oil under pressure. Whenever the pressure in the oil system drops below the pressure stored in the cylinder, oil is forced out of the cylinder and back into the system to feed the bearings until the oil pump starts pumping again."

 

Dare away, but I see what you've done there. You've made an assumption haven't you?

"Wrong" is a strong word when a better term is "if it applies" or "if applicable".

In this case, I work at home, have 6 cars, and do lots of bike riding. In the last two plus years, my 850R (as an example) has done less than 10K miles! My Volvo 245 Turbo has done less! After hearing a cacophony of top end racket after starting my E46 (and before it had oil pressure) a number of months back I decided my driving habits are bad for my cars. Precisely, how much any of them may sit.

So rather than saying you are wrong, I'll say your diatribe doesn't apply.

Now I love apex strafing so don't think I intend to just let the car sit. But driving everyday is NOT something I do. So when I've come back into town and feel the need to blast, the only thing I'd like to see suffer are the tires.
