Had to take radiators out and send them to be cleaned and also cleaned the entire radiator system with Shout detergent multiple times.

Seeing more posts now, though, of engines being repaired under warranty.

Lots of labor plus machine shop work to repair the head (if repairable).

How come it is for every engine related problem, every porsche owner wants to 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.

Help.... A long time lurker I work with some other Porsche guys who have encouraged me to post here for information.
My car is 1999 Porsche C2 Tiptronic. 117k miles. Extremely reliable.
ODBII codes: six are showing
P0300 Cylinder misfire detected
P0301 Cylinder 1 misfire detected
P0303 Cylinder 3 misfire detected
P1126 manufacture controlled fuel and air metering (there is an oil separator hose leaking on the driver side)
P1124 manufacture controlled fuel and air metering
P1531 Idle control??? input controlled vehicle speed
Symptoms: noticed low oil, and topped it off 2 days ago, strange as no leaks and never ever burns oil. Also noticed a louder than normal valve train rattle.
Cleaning the car I opened the coolant reservoir cap and noticed brown milkshake oil coolant mixture in the reservoir. The car is not running hot but in retrospect seems degraded as if it ran some low octane gas.
I was out of town and carefully babied it home this is about 25 miles. I notice the oil pressure was at 3bar and dropping. I stopped check oil level and put in one quart.
4 hours later started it up again and the oil pressure is back up to normal pressure levels.
Oil in the coolant. I notice some steam from the oil fill tube as well.
Is this the dreaded blown engine ?
Or perhaps an Air oil Separator? One small puff of white smoke on start up not much else.
I am searching and reading but your input is most appreciated.
That is exactly what happened to my 2001 996 at 57K Miles. Our first fix was replacing the oil heat exchanger located on the back right of the engine. Your mechanic will know where that is located. That did not fix the problem. So I bought a new engine from the dealership $8500 plus tax and paid a local indy $1500 to install. Had to take radiators out and send them to be cleaned and also cleaned the entire radiator system with Shout detergent multiple times. While we were at it we added the center radiator like the GT3. Does your tiptronic already have the center radiator. If so, then you have three radiators which need a thorough cleaning to remove the oil in them.
Everything works like a charm and the engine is warranted 2 years unlimited mileage. You are lucky to have so many miles.

Seems like symptoms of a blown head gasket. If that is the case, that can be fixed / replaced.
How come it is for every engine related problem, every porsche owner wants to replace the engine? Are these engines not rebuildable?
It's something that got started by Porsche and cars under Porsche warranty. If anything breaks other than IMS/RMS. the engine is replaced and the old one sent back to Porsche. I believe this also lead to the unavailability of OEM engine rebuild parts for the 996, since only the Porsche factory was rebuilding them. So, even if you wanted to rebuild, you did not have the parts for it.
Seeing more posts now, though, of engines being repaired under warranty. So, maybe we'll be getting rebuild parts soon.
And the point or dredging up a 6.5 year thread to ask what the OP did when they haven't posted since opening this thread?
Oh yeah, you're a useless troll. So much for my holiday wish coming true...
It's actually so desperate...it's starting to get funny!
Hey KK...since you are apparantly living in 2008 here's some advice. Buy real estate. Lots and lots of real estate. And...if the Giants are in a Super Bowl, bet against those losers.
It's sad that we have to put up with this douchnozzle...but we can't post pics with nipples...
Hey all,
Related type of issue, I'll start with I just bought this a week ago. 2000 996 C2 runs and drives great, but I found what must be oil/water mix (white and sticky) in the coolant reservoir. I have checked the dipstick and the oil is perfectly fine, temp gauge stays steady at about 195, and the oil pressure runs from 1-2 at idle and up to 3-4 when driving hard. All of my gut says it's a head gasket but the motor has no other symptoms than the goo in the reservoir. This was a new buy from a dealer that I am going to talk to on Monday. I feel pretty dumb for missing it during the test drive but here I am now.
If you do some searching on this site you'll find out that it is NEVER the head gasket. Most likely you have a cracked head, which is more common in MY2000 cars. The good news is that it can be fixed. I'm sure others will chime in. The first thing you need to do is stop driving it. The second thing is to get the coolant system flushed ASAP.
I think you should ask the dealer to fix it or take the car back because it's not going to be a cheap repair if it's one of the heads. Lots of labor plus machine shop work to repair the head (if repairable).
I agree it's very likely one of the heads and not the head gaskets but a more thorough inspection and diagnosis will be needed to confirm that.
Seems to be a bit of a recurring theme this, I've read a few things saying I just bought this 996 and.....
I think what happens is someone has had the car for a while, notices a problem and reads up on it then decides, let's get rid, probably trades it at a dealer.
The car is then sold as a px by that dealer or moved through the system to another dealer.
The problem is so slight at first it doesn't get picked up, the car is running fine etc
Then someone buys the car and after a couple of weeks might notice somethings not right!
The dealer probably wasn't aware but it's their fault for not checking the car properly so I would take it back and get a refund if poss.
There's going to be money and time needed to sort it out, you'll be out of pocket probably having to deal and contribute to repairs and wait with no car while it's in the shop, then you need to hope they send it to a good shop because a lot of places are clueless with these cars going round in circles not knowing these engines .
If you can get out of it , if not don't pay anything towards if you can help it and insist it goes to a place who know Watercooled 996 engines , even good air cooled garages can struggle
Yes, but the latest occurrence is from yesterday. And yes, the poster should have started a new thread, but he is new to ownership and to the forum so cut him some slack.
Thanks for the responses, Got ahold of the dealer and I'm taking it in to them to confirm the head and then move forward with hopefully a fix. Still love the car. Should I post this sort of thing to a new thread in the 996 area?
It was about 10 years ago and 50,000 miles ago that I had my intermix. Fixed it myself and it is still running strong (although it does need a new clutch master cylinder��). So these engines can be fixed��
