Secondly, we would never use nor recommend an FVD oil pan.
Leading evidence: 'Recommend fvd oil pan' (no explicit attributable resolution; this is a reported action or suggestion).

I can see small pieces left over on the bottom right part of that repair area.

You can repair cracks using epoxies with almost no visible signs.

I can tell you this, LN Engineering would replace your entire engine casing before resorting to flinging epoxy like that on your 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.

2000 996 C2 with about 5K on rebuild from experienced Indy, using Nickies and other recommended upgrades. Saw there was an oil leak, got it up on a rack, and found a patch of epoxy or JB Weld. Rebuilder says LN Engineering probably did that to stop porosity leak (doubtful). I�m thinking more like a case crack from over-torquing a bolt. I plan to get a second opinion to reinforce getting possible reseal, etc., but would like to get the 996 community ideas on cause and recommendations on moving forward.
Wouldn't it make sense that an experienced indie would report something like that before embarking on the rebuild? I'll answer; of course it would.
Given that, my money's on the indie, not LN.

Kinda lools like an ameratur hour repair. I would have put a die grinder to it an cleaned it up some.
If its not leaking oil then i really wouldnt worry about it.
That epoxy was definitely put there AFTER the engine was assembled. You can see it globed onto the head of the case bolt.
The crack was probably missed and only discovered after the engine was already assembled . This area is known for damage from engine failure, usually the timing chain gets wadded up around the IMS and causes a crack.
Looks like this was engine # 046 by JEV (that's not a factory stamp).
If it were mine, I would do like De Jeeper said, not worry about it.. or if it was leaking I would clean it off and do a better job of stopping the leak/sealing it up.
I don't get any of this. Not at all. This is really stupid -
"5K on rebuild from experienced Indy" "Rebuilder says LN Engineering probably did that"
So your 2000 C2 engine has been to LN Engineering for a rebuild, and you have 5K on a rebuild of your engine from an experienced indy? I can tell you this, LN Engineering would replace your entire engine casing before resorting to flinging epoxy like that on your engine. That did not happen, and your "rebuilder" is an idiot for making that suggestion.
Also, getting a second opinion? What? Second opinion that someone somewhere took a slather tool and slathered epoxy on your engine casing? Tell you what...send your car back to Stuttgart Porsche and buy yourself a Honda. Then all the world will be roses and nice.
Looks to me that this was epoxied before the light grey one was applied. I can see small pieces left over on the bottom right part of that repair area. That epoxy is a lot darker than the new repair.
As said above, leave it alone until it leaks.
I'd stop right there with that statement and think about it. Who do you think is covering a mistake?
LN would NEVER use JB weld. Never!
Also, if there was JB weld before the work started, a good rebuilder would bring that to your attention.
Another thing to mention. This JB weld was put on AFTER the engine was assembled. How do I know? Notice where the JB weld is covering... It's covering the engine halve point. Therefore, it was put on the engine after the fact.
Sorry, but we don't put JB Weld on any blocks. If there is damage on the block, we weld the block. And for the record, we did not build that engine. By the serial number on the block, I can tell who we did that block for. It was an east coast shop. However, I can't say for sure that this shop put JB Weld there or someone else did after the fact.
Secondly, we would never use nor recommend an FVD oil pan.
Thanks, all, for kind responses, quite a conundrum. I agree with the comments, and, Charles, in no way think LN Engineering would do this to a case, I was just repeating what the rebuilder said. I echo the comment above that a rebuilder receiving a questionable part should inform the customer and send the part back. My problem now is proving who did what, since correcting the issue would, worst case scenario, be a $20K rebuild. Engine rebuild was done due to head crack / coolant leak at 105K miles (car is a keeper until I’m too old to drive and it needs a PPI).
@Jake: Not that I know of, the imsb that came out was actually in pretty good condition for 100K miles and looked to be OEM. My thinking now is that the case was damaged in shipment from LNE or thereafter, and wasn’t discovered until oil was added and engine run-in by Indy?
