I could have saved $3,500 if welders or repair shops had experience with these cases, but the dealers seem to want to throw them away if any internal problems get costly to correct and have no experience with welding cases.

I can't visualize where your hole is, but these cases are not that strong, and to weld it properly, you would need to break the case down...so it would probably be cheaper (and safer) to just replace the engine.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

I am having difficulty finding a welder who has actually worked on a 1999 996 engine. I need a new engine because the intermadate shaft is broken in my original engine. My repair shop has a 1999 with 10K miles on it but it was backed into a parking stop and has a hole the size of a quarter on the bottom
left corner where one of the bolts would hold the oil pan. Does anyone know
if the aluminum used in these cases can be repaired and does it take any special equipment or knowledge. I could buy a remanufactured engine but it would cost an additional $3,500 to purchase the used one is available for $3,500.
Thanks for any information.
Well, I have attempted to weld on the valve cover of a 996 and can tell you that it's not aluminum (at least not pure al)....seems to be magnesium and that has to be welded in a vaccuum chamber. Not sure if the case is the same, but it sure seems to be.
I can't visualize where your hole is, but these cases are not that strong, and to weld it properly, you would need to break the case down...so it would probably be cheaper (and safer) to just replace the engine. Maybe someone else has had a more positive experience.

Thanks Mike,
I have heard the same from a welder that it may be a magnesium silicon base that is difficult to weld. That might be why the insurance co replaced this engine with a new one in the first place.
The hole is exactly where the pan bolt on the botton left corner would be threaded, you can see
1/4 of the thread left and about 1 inch of cracked missing corner going up into the bottom of the case. The bolt is lower than the pan and thats what the parking stop hit and broke off the corner.
Looks like I am going to ease my mind and get the remanufactured engine at $7,000 plus
installation at $1,600. So for $8,600 I will get the 2 year warranty that only includes parts no labor.
I could have saved $3,500 if welders or repair shops had experience with these cases, but the dealers seem to want to throw them away if any internal problems get costly to correct and have no experience with welding cases. Also the cost to split the case to work on it is not worth the time.
Many welders feel that if you leave the case together oil will seep into the weld and it will not be
a good weld.
