Get yourself some silicone to seal the part# 1 to the engine block. It is the crankcase breather going to the oil reservoir, no seal provided....

 

good post but you've missed one pipe, there are eight not seven. The last one is on the bracket that holds the power steering pump.

And

 

You got me! I know there was two curved one but did not locate it in the parts cat. Can you? Is it the one I just added on my post + do you think the parts circle is needed....Thanks a lot!

 

Another one to do as mention by And996tt, thanks!

Finally one pipe on the steering pump bracket (curved)

Part needed : item # 5: 999 707 298 40 X 1
item# 15: 999 707 204 40 X 1 seal between reservoir and steering pump

Also the seal between the steering pump and the reservoir if removed:

 

yeah good job JP, i would also order the coolant hoses, the big one, i have seen one fail on the track on a GT3, same as the turbo i beleive, it litteraly split in half in the length side, not accross it, pretty weird.

Good time to change the fuel filter and the coolant tank if not already done. I have my tank ready to go in when i do my engine with the welded fittings next winter. Tank is already in stock and fittings are in the mail.

 

Very good point Alex. I have found 2 links for part# if needed for the hoses. Suggestions from Kevin, fdorn (Frank) and Paulunm on Rennlist

Anyone know what happened to the DIY coolant pinning thread (not the sharkwerks one)? I can't find it anywhere.


N/M I forgot it was on rennlist.

Here is a link though to anyone interested.

Wow! I was not aware of this thread and also was not aware of the threaded fittings option!!! What a clean job!!! Thanks for posting heavychevy!

 

I sent that thread, along with sharkwerks thread to my mechanic to study. He's really good at that type of stuff. I'd rather the pin option honestly as not one case of pinned fittings has reported leaking, yet at least a few cases of welded ones have reported it. Plus I don't want to pull the engine out just for that.

 

Man something must be in the air. I am seeing lots of threads with this failure all over this past two months. It was quiet for a while.
Lots of good repair options luckily.

 

Has anyone seen a 2003 or 2004 996 Turbo with this failure yet? I have not seen one.

 

IMO, this failure is just a matter of time on all 996TT's. There may be a few out there that for some reason never fail, but I think the majority will fail over time and use. I had one of the earlier failures, as I drive my car a lot and it failed at roughly 7 years, 80,000 miles a few years ago. We replaced it with a brand new, off the shelf Porsche OEM part. The new OEM part lasted 6 months and failed on the opposite side of the first failure. At that point, I mentioned that I felt this was going to become a common occurrence as these cars age...I think we are seeing it now and I don't think it's going to stop.

 

The threaded option is probably "enough"..thoughts?


And, I put a thread up on rennlist in the de section/racing section....3500+ views and a lot of vitriol.

Hoping NHTSA makes this a recall. There is a list of events in the 997gt2/gt3 section on rennlist....
