The engine wasnt that dirty so I used engine degreaser, mean green, and some brake cleaner.
Leading evidence: 'Use engine degreaser, mean green, and some brake cleaner' (no explicit attributable resolution; this is a reported action or suggestion).

I admire your garage skills and your endeavor to have a perfect used Porsche.

This has been used to clean blocks and heads but unless KK plans on disassembling the whole engine bay, dry ice blasting isn't meant for rubber, plastics, wiring and such.

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.

Took a break from T-Day stuff to get engine out. I dropped it where I could just roll it a few feet for cleaning outside. Any suggestions other than the usual? This project proves that dropping the engine and trans is not a hard DIY if you just take your time. If I can do it, anyone can.
Now that it's out, why not just trade it for a GT3 engine, so you don't have to worry about it all the time? You'll probably get a decent value for yours, and it looks like you can get a used GT3 engine on Ebay for 14k. You're probably only 4-5k away from having arguably the best engine that Porsche has made in a long long time.

Nothing is really hard. I used jack stands, ATV jack, trans jack.
I wish it were an easy swap. It would be worth considering.
The paronia on this forum is going to cause me to replace many parts as PM while engines out even though they are not even failing. The list (cost) never ends for these cars. All this at @58,000 miles sucks.
Hey KK.... you are Krazy. Id love to drop my engine someday, but only when I have to. I admire your garage skills and your endeavor to have a perfect used Porsche.
If I had to take the engine out, i'd be changing out every belt and cooling hose�.along with the timing chain guides, but that's me.
I guess it depends on the mileage, but i'm extra nervous when the car goes over 100k.
I actually removed the AOS and coolant tank first before the drop just to see how hard it is. Its such a PITA on the 02+ that I recommend anyone drop the engine to change it.
Im also changing some coolant hoses, water pump, T-stat, coolant tank, oil fill tube, and a few other things. Two of the vario cam solenoid cover seals were leaking a little so Im changing all 4. Their only $11.50 each, so may as well change them. Im sure other guys have noticed theirs leaking when they change the plugs. Photo courtesy Pelican.
I dont think Im going to change the chain guides because I have not seen any brown bits in the filter or sump cover. Mileage is probably too low for guide wear.
Whats depressing is that the coolant tank and oil fill tube look new but thanks to this forum, Im sure the tank would start leaking and the tube would break soon if not changed while engines out. The water pump has a very small amount of bearing play but feels smooth. Im sure it would self destruct as well if I dont replace it now.
It would be really great if you could time all these things at once, say at @60,000 miles. Unfortunately it was only @1000 miles ago I had the trans out for IMSB, RMS, clutch, flywheel, etc. Wish I would have waited and done it all at the same time.
Oh and BTW, my car easily passed the PPI by Hanz and the RAC crew over a year ago. The car was an "8" out of a "10". Every 996 purchase should come with a free complete tool set, lift, shop, and service manual.
You really are Krazy . Quote 'Thats actually funny because the interior has been the only thing that hasnt been a problem'. The next BIG problem is going to be your wife. The 'money pit' is certainly not an under statement on her part.
Buy some ear plugs. You are going to need them.
Nice work. Every time I see pics of an engine drop ot reminds me of my own project. Since you are replacing a bunch of parts that are still good, instead of throwing them out, can I have them?
This.
Also, I'm sure your car was an 8/10 at the time. As memory serves me, you really haven't had any issues have you? Yes, the AOS getting brittle and breaking sucks, but when you bought your car it was completely operational and wasn't leaking...I just don't see what the PPI at RAC being done over a year ago has to do with your car as it stands today...
Nice work... I bust your ***** about your constant IMSB harping, but I do think these cars were definitely made to be worked on by their owners!
Though dropping an engine just to clean it might be a
tad
excessive....
Here comes the style police: Hans Mezger's name (the engineer that designed the GT1 engine used in 996/997 turbo, turbo s, GT2/3 (RS) and a bunch of 996/997 race cars) is spelled without a Z..

Whoops... I thought it was 'Metzger' as well.
Looks like a pretty common error...

KK, you've got it this far apart, you may as well put a VF Eng. supercharger kit on. Injectors swap will be a breeze, plenty of room to run SC coolant hoses, and a lot more power.
"Mezger is a hereditary surname which is derived from the German word Metzger, which means butcher. There are several spelling variations for the name, such as Metzger, Metzeler, Metzler, Mezler, etc."
But you know with the translation being "butcher" shouldnt he have designed the M96 NA IMSB engines?
I am exactly like you KK, for me "normal" is what other people consider crazy. when i tell my friends that i will pull out my engine soon, they go like WHAT?? . and i tell them that it is just lifting the car, unbolting afew things and its out, thats how i approach it. of course it is a little more involving but you get the idea,
good luck with the job!
Now your talking bro! These guys are just messing with me most of the time but I do seriously consider any suggestions/opinions about what else to do with the engine while its out. I do not expect to do this again for a long, long, time. If I continue to drive 2500 miles per year, I should be OK until year 2033 for next IMSB.
KrazyK, great thread you started. A nice balance of education and comic relief.
I respect those that go this far to get it right. I don't have the skills, but I love to follow those that do.
If you can find someone to dryice blast it that's great.
Simple Green may be the best manual method, but it will grey the alloy if left on to long. Try to find the aviation/alloy type Simple Green.
This has been used to clean blocks and heads but unless KK plans on disassembling the whole engine bay, dry ice blasting isn't meant for rubber, plastics, wiring and such.
Remember any type of media blasting would be abrasive.
I found steam with any of the popular engine cleaners to be effective. Castrol Super Clean is also effective.
This is a good time to replace all the vacuum lines. Some are very hard to get to w/o having engine out or the intake assembly off. They appear to be 4MM and I was able to replace them with the Prestone brand.
The engine wasnt that dirty so I used engine degreaser, mean green, and some brake cleaner. I have replaced almost all small coolant lines, larger coolant hoses, and vacuum lines. AOS/OVS and coolant tank were super easy to replace! Waiting for new water pump and engine is ready to install.
I measured the minimum height required if using a 3 1/2" wood block (to protect sump cover) on a standard ATV jack. If you measure from the top of the rear wheel well to the shop floor, it was @44". If you use a 1/2" piece of plywood, it would be less, of course. I am able to re-install the engine with throttle body and everything on engine (except AC compressor).
After doing this, if I had to replace an AOS/OVS on a 996 again, I wouldnt hesitate to drop the engine.
The great thing about pulling out your engine 'just because' is it cuts down even further on actual miles driven, indefinitely putting off the imminent IMSB doom (:rolleyes).
While your in there might as well replace the mat velcro, upgrade the pedals, scotchgard the carpets, lube the seat rails, re/re clutch helper spring...
KK, do you do your own housework by chance? If so, I'm wondering how many times you replaced the drywall to install new lights and such? Maybe take down the entire ceiling to clean the HVAC ducts?
