You are likely correct, but let me dream. I may take a look at it this weekend just to confirm the source again. I have no problem contorting myself to work on cars. I also have a track miata which is the epitome of working in tight spaces. However I find it harder and harder as I get older. If too hard to get to then I may just have an independent Porsche shop local to me see if they can do it without charging me for a full arm and a leg.

 

Had a chance to get under the car today and to my surprise coolant leak is coming from entirely new area. Lucky me it’s coming out of the two holes under the transmission. I took my endoscope and stuck it up there anyways to take a look at Where the previous small leak was and everything looks clean and dry. The water distributor manifold and barbed hose fitting looked great as well, no leaking or from any of the other connections.

Next was to look in the obvious place that would cause coolant to be coming out of the bottom of the bell housing holes So stuck the endoscope up under the intake and bingo, found a nice pool of coolant in the valley.

Not sure if I should be relieved that’s what it is and that hopefully I can clean it out before the seals in the transmission get shot over the water distributor leaking at the back of the motor. Going to slowly start taking apart the top of the intake and diving into what possibly could have sprung a leak under there. It is a 957 so already has the aluminum pipes but I know there are still some plastic pieces under there.

Got intake off but before I did I could see one culprit immediately. There is a plastic nipple bolted to the block on both the right and left side on the front of the engine just under the intake. Both sides had telltale sign of pink dried crust of anti-freeze around them with a small pink stream running into the valley. When I went to wipe the crust off the one on the driver's side which was the worse looking of the two, I barely touched it and the plastic nipple broke right off. The other one didn't seem as brittle but it's obviously not sealed and is leaking as well. I couldn't see anywhere else it could be leaking from but once I replace these two I'll pressure test it to make sure. I can actually replace these without taking the fuel runners off, but going to take them off anyways so I can clean all the dried crusted antifreeze out of the valley.

Any pointers for how to clean that area out and do I worry about trying to clean up the dried antifreeze that got into the bellhousing?

 

Another follow-up. Spent some time cleaning up the absolute mess of coolant the last couple of days. New coolant vent line arrived and put it in last night. Will finish up putting it all back together today. I think I have a beef with the Porsche dealership service department where I bought it from. They had performed a full engine out service so had things apart and put back together and let's just say they cut some corners and missed some stuff which likely caused this leak in the first place. The old vent line were missing the rubber o-rings which creates the seal to make it water tight. No wonder there was signs of coolant weeping out them. There was also a plastic cover on the starter battery terminals which was broken in half then duct taped back together. Some of the various vacuum lines at the back were not tucked in and snapped into their proper mounting areas.

Always support a good independent Porsche mechanic and not the stealership service department. That is all.
