getting oil moving around the engine after storing it for the Winter

[jvcuenca]

Anyone knows the trick? I know it's almost Summer, but this would be good to know in Winter. Thanks!

I found this website but it didn't say HOW to do...Just shows a guy messing with some electronic parts in the rear trunk...

I hibernate my car every winter (the past 3 years). I plug in the Porsche maintainer, and don't touch the car until April. Before I start the car in the Spring, I put the car in 5th gear, and manualy roll the car out of the garage and partially down the driveway. I can do this by myself with a few good tugs on the real wheel. You can hear the engine turnover. Then I start the car as normal.

Here is a simple method to transit oil through the critical engine components prior to first engine after storage:

Remove the fuel pump fuse found on Row C - Position 4 (25amp) then turn over the engine with the starter.

Did you trickle charge the battery over the winter? If no, then I suggest trickle charging the battery prior to cranking the engine over.

To get all 6 cylinders thru the 4 cycles takes 24 revs; I am not sure what the rpm of a starter is, so I ran the starter without the fuel pump fuse on two separate starting cycles. Each cycle for a 10 second period with a one minute rest between cycles. I think 30 seconds would be too long resulting in excessive starter heat and possible damage. (Loren may know what the time cranking limits of a starter are; I don't, so 10 seconds is way safe with a rest between cycles.)

I just performed this procedure last week; it works.

I know a lot of people use "trickle charger" and "battery maintainers" interchangeably. But what you want is a maintainer, not a charger. Battery Tender is one popular brand. I have the Porsche version like White987 has, and it was not all that expensive.

I had forgotten the old fuel pump trick. Good post. I used to pop the coil wire off. But you are still just slowly moving un-lubed parts together.

Shooting some oil into each cylinder before and after storage helps too.

David, this may be a very good method, but the problem I see is if (and this is a BIG "if) the piston ring siezed to the cylinder wall, the power and torque of the starter motor could do some damage to the ring, piston or cylinder. The method I use and mention above gives you a little insurance before you crank the car.

When I start my car each spring, it sounds great. No noise. No tapping. No smoke. Nothing. Sounds like a pre-warmed engine. I change the oil prior to hibernation. And use a high quality oil (Red Line 5W40 not on the Porsche approved list. I know!). Garage is heated.

That is very incorrect. Two complete revolutions of the crankshaft covers all 4 cycles on all cylinders (4 cylinders on these engines). The pistons and valves are not waiting for each other to finish up before the next one starts to move. They all move at the same time only offset to each other to make sure they do not fire at the same time.

However, two revolutions will not be enough for the oil pump to move oil around the entire engine.
