UPDATE

As I search for the expansion tank I decided to start with the basics and tackle the timing belt water pump. 3 hours later trying to get just the cover off I gave up. Went back to all the books and research and videos and.......

There is a hose overtop of the cover that is not supposed to be there.

...and the fun continues.

Cannot remove the cover it that is in the way. Stay tuned.

That pipe should be there, its aeration of the turbo oil drain, which was one of the upgrades porsche did on this engine over time. I don know how much stuff you have removed, but with a non modified cam cover you will probably have to remove most stuff in front of the engine.

When its off you will have to take your angle grinder and cut of some small tabs, the ones that are causing the trouble. After that it will be a breeze to remove, im not sure what sadistical designer who made that cam cover, but thankfully its easy to fix.

I do still have my old removed coolant overflow tank, if you want to stay that way; was going to sell it to another boardmember, but he disappeared.

But the 944 tank is so much nicer...

I use the 944 tank too, but its an NA so I don't know if it fits the same on a 931. If there in an ignition module on the fender well it needs to be relocated I think.

Been cleaning the car interior and the engine bay.
Researching, gathering knowledge, gathering parts on the vehicle while I wait for the mechanic to reach out again to do his once over.

Such an incredible vehicle top to bottom! Love that its not perfect and needs some love!

I did start it the other day after correcting some of the missteps that I found.
Started smoking on the right side, possibly some burn off but didnt want to risk it so I shut it down.

Addressing the Carbon canister, the airflow hoses that were missing. Was hoping to address the Water pump and timing belt and the oil leaks but waiting on mechanic first. Might just forget it and tackle it anyway. I just didnt want to send it to him in pieces!

Cheers

Question about TDC for Timing belt replacement.
TDC on the camshaft cover, check!
Not TDC on the oil pump pulley however.

Seen a lot of different opinions and now have to ask.

Do they BOTH need to be TDC?
or
Just the Camshaft cover is ok?

If they DO, can you move the oil pump pulley after belt is off to realign?

Cheers.

Are you sure you used the mark at the back of the camshaft pulley?

Pull # 1 spark plug and stick a plastic (or a recycled organic seaweed/bamboo version, if so inclined) drinking straw in to sit on top of the piston. Now turn the motor over by hand using a socket and bar on the crankshaft pulley.
Get the straw 'on the rock' at TDC and BDC. That is, where the straw is at it's highest point and lowest point. Check your marks on the crankshaft pulley and camshaft pulley. Now you will be able to ascertain whether the timing marks line up.

Figured out the TDC thank you for the suggestions.
Car is back together.

Water pump and timing belt replaced. Part removed were refreshed or replaced in the reassembly.

Moved on to the coolant part of the assignment. Filled with coolant opened the bleeder screw and now car won't start. uh What?

Key in, Turn once to battery and fuel pump starts, turn again, clicking only.
No electrics were changed or removed. Spark plug was removed for TDC but was replaced same way.

Brothers and Sisters I need your guidance...

Possible low battery charge. Low current draw items will work but starter solenoid wont. Turn on headlights and watch as you try to start the engine. If the headlights dim quite a bit the battery is low.

I thought that as well.
Actually went as far as jumping it.
Didn’t look at lights though.

Car was finally running prior and now nothing. Crazy car!
