I hate to do this but I kinda don't want to have to read all of the pages of this thread. #sorrynotsorry

Is the guide on Pelican Parts still the most appropriate one to use? I have a 1999 C2 and am just now finally getting around to installing my kit.

Thanks!

Edit: I have a 4-post lift. Does this make it possible to remove the AOS from underneath without having to remove the drivers side intake manifold?

You might want to go to post #412 and go from there. Not on a 1999 but I made a very detailed write up for 996.2.

I’ve done it twice from underneath.
Helps to lower the motor with getting to connections at the top.
Only removed the throttle body and the crossover pipes.

Pete's documentation on post #412 is the best one for 996.2 , I tried to attach it post #1 but for some reason I can't edit post #1, may it has been archived?? I dunno...but it is definatly the most detailed for 996.2 .

No need to remove the intake on 996.1,,, the AOS bolts can be accessed from the bottom....Infact the 996.2 can be done without removing the intake also, but the bolts come down from the top and takes quite a bit more fineese....Most professionals don't struggle with this, but some do.......most average DIY'ers struggle with this, but some can breeze through ( Kris Murphy) ..it's crazy the amount of spread on doing this job....lol

For 987.1 Boxster and Cayman there is also a video made by a YouTuber with channel "help me DIY" that shows him installing a UAOS with Track Drain on his 987.1....He is not a professional Mechanic , just an average DIY guy..

Thanks folks!

For those struggling with the Norma Quick Connectors here is a couple of tools that will ease the pain of releasing those in tight spaces...

Hey Skip, hope you're well. Just PM'd you but reposting here to add photos.

After a bit of travel I'm wrapping up the UAOS on my 2003 996.2 C4S and I'm in a pickle. I can't figure out how to route the drain line from the UAOS reservoir back to the oil filler tube. I currently have the drain line running behind the alternator, coming out on the left side of the alternator between the alternator and the manifold. When I move the reservoir into position, the hose gets mashed up next the manifold. Am I supposed to run the hose over the top of or in front of the alternator? (If so, I sure hope I don't spring a leak!)



Also, how am I supposed to route the flex line (is this the brake booster line?) through/around/under the UAOS mount to the manifold? Nothing seems to make sense. I've tried running it behind all the UAOS lines, between them, in front of them... Nothing seems to work.



Thanks

The reservoir is not in the right spot - It does not look like you will even be able to bolt the support bracket in it is shifted so far right.

This is how that should look.

Your routing of the drain sounds fine.

Porschetech3

The Track drain should route behind the alternator like shown here...




The brake booster hose should route like this over the UAOS hose......... The Accumulator mounts to the Intake with two screws provided and the changeover valve relocation bracket as shown here..

If you need to we can do a " FB Messenger live video feed" to sort it out, should only take a few minutes...

Thanks, Skip. I did end up getting the line connections made, although they're pretty tight. I ran the shortest route I could find for the track drain line but another 1-2 inches of hose would have helped better route the drain behind the alternator. My line is almost (but not quite) sandwiched in there to get enough slack to connect to the track drain.

I do have a question on the electrical connections. Where to these little guys connect? They seem to want to connect to the coolant level sensor in the overflow reservoir, but they don't appear to be an exact fit. Do they go somewhere else, or do they just need a little persuasion?



Here's where I am, in the home stretch. Seems like it's going to be tight fit when I lift the motor back into position. I've also noticed a bit of coolant weeping at the cap on the line coming up from the water pump below the oil filler neck.

imhighlander

NVM. Figured it out.

Porschetech3

Glad you got the low coolant switch connectors plugged in, just have to get them perfectly aligned..


The silicon rubber coolant cap doesn't go on the plastic connector peice, that's why it's leaking a bit... It goes down below the alternator on the engine it's self and elimiates those hoses and plastic connector..The size is slightly different..






Looks like you are on the home stretch !!

@Porschetech3 running with no leaks yet. But the UAOS unit that connects to the plenum is interfering with the fan so the lid won't close. What the hell am I doing wrong? I mean, it closes, but the fan presses against the unit to close the lid.

Porschetech3

This hose is not all the way on the flow regulator, also check the hose on the back to make sure it is all the way on.

If it still touches just trim a little off the back hose..
