So today I go to my newly delivered fabspeed exhaust on and I once I have bumper off and things all cleared out, I noticed a crack on the right side of the rear muffler mounting plate (1st picture). So I proceed to remove it to get a new part to replace. There are 4 torx bolts holding this plate on (see 2nd picture), so I go to remove the bolts. I loosened the bottom 2 and the the top 2., I take out right top then left top bolt. When the left top bolt was almost out I started getting a coolant leak at the rubber seal between the 2 metal pipes! (See 3rd picture)

So instinctively I try to tighten that left bolt, only to find that it's not going back in! I take the bolt out completely and I try to put in back in and it won't go! I take a look inside the hole and it appears the bolt ties in the mounting frame, some rear coolant pipe and to the engine block. And now it looks like the coolant pipe piece and the engine block are not lined up. I tried to use a floor jack to lift the coolant pipe and the engine block with no success. I ended up towing the car to my mechanic where he will look on Monday to see what happened. Anyone else have this happen before or know what happened?

 

Mounting plate

 

Seal where coolant leaks

 

Never seen that before. Why they would have the mounting plate as part of the support for the cooling line is beyond me. I assume that the same reason why you can't get it back together is the reason why that piece cracked. High heat and stress like that, overtime, could do that to the metal. I am surprised with all the aftermarket shops out there changing out the heavy exhaust systems, that no one else has seen this before.

 

Could this be repaired damage??

 

Hey guys so I have some good info here.......My mechanic looked at it and he said those 4 bolts that holds on the exhaust plate also bolts together the rear coolant pipes and the engine carrier plate. So if these 4 bolts need to be removed, the engine needs to be supported with a jack so that there is no movement. If not, you will get what i got and the engine carrier, coolant pipes get misalgined and the rubber seal between the coolant pipes gets off line and the coolant will leak.

Poor design by Porsche if you ask me.

 

Bad design by Porsche? NEVER

 

Now that is complicated for no reason.
