Swapping engines

[Gilles]

Did you replaced the tensioner pads already? Then you should be ready to swap the engines right? :-)

I was planning to put in the rear main seal next, but I've been psyching myself up to do the cam chain wear pads — reading, watching videos, making sure I've got everything I'll need, wondering if I should replace the chains** at the same time. Before I put a ratchet on the cam covers I want to be absolutely certain I understand each step. I'm getting close.

**On a 39K-miles engine I would expect the cam chains to have minimal wear, but then, chains are relatively inexpensive. Still, where do you stop throwing new parts at it? Everything I'm doing to this engine I regard as critical stuff, including replacing the motor and transmission mounts. Sure, it would be nice to replace the AOS; water pump, coils and plugs, oil pressure sending unit and sensor, fuel pressure regulator, crankshaft position sensor, positive crankcase ventilation conduits, etc., etc. Then I could drive to the poorhouse in style! After I make a decision on the cam chains I think I'm going to draw the line there. It's getting close to a year since I've driven my baby. I'm jonesing to get it back on the road.

Of all the stuff you mention I would only consider changing the AOS simply because it is a lot easier to do with the engine out. Water pump, coils, plugs, CPS etc can be changed when and if necessary with the engine in the car. Chains should be fine.

It would have to be an aftermarket AOS, because the chances I'd shell out $1650 for a Genuine Porsche AOS are practically nonexistent. I much prefer Amazon's $55 alternative:

Where did you get the $1650 price? Pelican has a genuine Porsche for $192.

Oops! I searched for "986 air oil separator" and it came up with this:

https://www.pelicanparts.com/More_Info/98710792600.htm?pn=987-107-926-00-OEM&bc=c&SVSVSI=

If I hadn't been in a rush I would have noticed the form factor was very different.

You won't be so happy when it dies after two weeks. We only use the factory part.

Sunset Porsche out in you neck of the woods has them for $156.

I can't seem to find that AOS at Sunset searching for "AOS" and "air oil separator." (I'm not having much luck searching for parts, obviously.) I will go with factory parts whenever possible. Except, for example, when they want $265.48 for an "air tube," and that's with Sunset's $22.59 discount:

(Pelican won't permit links to competitors' products, so replace asterisks with "sunset.")

Give Luke and the crew at Sunset a call, they will hook you up at reasonable $.

Luke at Sunset is a gentleman!

AOS is part # 996-107-023-04 I would also order one of these as it makes installing the lower hose clamp much easier - 999-512-630-00
