Some of these issues come from sump and cam cover maintenance when too much sealant, or the wrong sealant is used.
One of the sealants recommended is Loctite 5900, this sealant works well, BUT it has a big tendency to either not apply heavily enough, or apply too heavily with a very small "sweet spot" to work with.. The Drei-Bond sealant is similar as well. I have used many other sealants in this area, that I like better, but all have their compromises.
People generally think that "more is better" but they don't know that they can be a minister of death to their engine with that mindset..
That said, even Porsche dealerships use too much sealant on occasion..
You'll see a tech article on this topic soon, I just talked to the Editor of a Publication about this and he wants me to give him the input and pictures for an article on how to inspect the pick up tube for obstruction and how to reseal the sump without making the situation worse...

anytime Jake,,, the 996 community needs to be aware of the work your doing here as well as being aware that porsche didn't do their homework when creating the M96 motor...

Motor is available again,
Long story.....
My buyer lives out of state and asked that a compression test be done before shipment. I liked that idea a lot as I certainly don't want anyone to have any surprises. We hired Chris Cervelli to come out and do a compression test. Everything was fine except one cylinder that would not hold any compression. Upon further inspection, we found that one exhaust valve was not closing.
I then hired a dealer technician to come out on a Saturday with proper tools to take the cam cover off and ascertain the problem. Unfortunately, this took quite a while and during this time, my buyer found what he needed elsewhere. What the technician found was exactly what he had suspected..... a bad lifter. Pretty easy and inexpensive to replace.
In any case, the motor has now been inspected and should be good to go with the exception of the lifter. I would share contact info for both technicians for any serious buyer so you could talk to them yourself.
Given the need for a new lifter and a bit more labor before installation, my asking price is now $5,500. Further consideration possible if you can pick it up at my house in the Southern suburbs of Denver. It includes wiring harness, AC compressor, alternator, coil packs, etc.

Relatively cheap insurance, I think. That's why I bought it while I had my 996. Of course, having a spare motor in the garage is a virtual guarantee that the original will never fail. It's a similar concept to my perfect record of carrying rain tires to races for 6 years and never having to use them.

Will this 1999 Non e-gas Motor work in a 2000 996 C4 e-gas.
I'm assuming the internals are the same with the exception of the IMS bearing maybe being a singe vs double-row. I'd just bolt my Throttle-Body up to this and it would just fire up?
