ran the car for a while and took the laser thermometer to the exhaust manifold to find which cylinders were missing.

Then tested fuel pressure and it read good, so nest was spark.

tested O2's all were fine now, tested MAF, was good as well.
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.

So I had a little disheartening discovery today. On Saturday I had a bad misfire, so had it towed to my shop. I thought it was something simple like an MAF or O2 sensor since it acted the same way it did the last time my O2 sensor went bad. Had a family trip planned on sunday so quickly looked at it and found a bad O2 sensor... No big deal. Went on my trip, came back got an O2 sensor and thought my problems were solved. WRONG. still missing. tested O2's all were fine now, tested MAF, was good as well. Then tested fuel pressure and it read good, so nest was spark. tested coil packs and harnesses to coil packs all were good. This was getting a little more difficult. ran the car for a while and took the laser thermometer to the exhaust manifold to find which cylinders were missing. Turned out to be number 6. pulled the number 6 plug and it was covered in fuel, but after cleaning it it was not fouled. I figured clean out the cylinder with the air gun and try again. I got a face full of coolant. I then assumed head gasket. but after talking to other shops and such I learnt that the probability of it was low so I took the Boroscope to is and found it D-chunked
So either new motor or rebuild. I found pricing and time wait to not be very good. dealership quoted me $25,500 + $19,000 core that may not be returned for a remanned motor. LN and Motor Meister were quoting alright pricing for a 3.8 build but the wait is longer than I want. The fiance made me a proposition that I seemed a lot better. Get rid of the C4s, get rid of the Civic, and I am allowed to buy a 997 GT3
Now I need to figure out what my car is worth, and what I can get for it. (Will not part it, since I am too emotionally attached and don't have the time)
Here are the details
2002 Porsche Carrera 4s
Canadian Car 3rd owner
114,000km = 70,800 miles
6 speed
Black on Black
Sport Seats
Turbo wheels
The Good:
-New clutch, pressure plate, all the bearings associated with it and machined flywheel done 5000km ago with OEM parts
-Transmission recently serviced and in good shape, no grinds
-Diff's recently serviced again good shape and new fluid
-Drive shafts in good condition no play
-Cats in good shape as far as I can tell
-PSE hacked mufflers that are properly tig welded with turbo tips
-OEM Exhaust tips
-K & N Intake used for about 5,000km
-Front brakes (pads and rotors OEM) done at 99,000km with 80%, rears at 30-40% Finish on calipers isn't great though
-H&R lowering springs with OEM struts in good condition
-Turbo wheels in good condition except rear passenger which could use refinish
-Brand new Michelin Pilot Sport Cup tires 295/30R18 and 225/40R18 less than 100km
-50% left on Dunlop Winter Sport 3D tires 285/35R18 and 225/45R18
-Interior in pretty near mint condition save a couple stretches on back seat leathers and paint chip on driver door car storage silver paint
-OEM Bose speaker system
-Pioneer Double Din DVD Nav unit
-Porsche OE Carbon Fiber shift ****
- OEM Porsche leather shift **** never used
-Power Sport Seats, unpainted backs, Passenger in near mint condition, driver has some bholster wear, but no cracking or anything serious (I am just very picky)
-Newer headlight assemblies
-Air bags never deployed
-3spoke steering wheel
The Bad:
-Obviously motor is shot, but has had a lot of recent maintenance
-Side skirts are the unpainted style, Passenger side has a crack, driver side missing a chunk from driving over a curb
- Front bumper is cracked, staff member backed a truck into it
-1 door ding on passenger side door, no paint chip though
-Misc scuffs and swirls from driving a car, most can be taken out with a good cut and polish
-Some of the under trays are cracked and missing. Again typical driving on ****ty roads
-2 comprehensive insurance claims
1) 2006 ($5000) repaint front end and replace headlight assemblies due to typical rock chipping (have invoice)
2) 2008 ($6000) Deer accident, deer ran into car while stopped smashed driverside windows, mirror, tore leather in back seat, 1 dent in rear quarter, 1 on door, and micro abrasions in paint
Like I said, I am not willing to part it, I don't want to invest any more money into it, and I dont want to have to sit on it for months. Given the above info, what do you guys think I could get for the car?
Also if it makes a difference, the car is Canadian, and located in Alberta at the moment.
Thanks
Jordan
Too bad about your D chunk Jordan. From time to time there seem to be people interested in rollers so they can strip and modify for the track. I'd also suggest posting in the racers forum. GL The above price sounds like a starting point.
Agree with Quadcammer unfortunately. With the repair history, wear and tear listed and d chunked motor $8000 is heartbraking but accurate in my opinion.
The retail difference in you average new or used car is 20-30% more for a Canadian vehicle than the same one down in the states. Not sure if it applies to Rollers though
If you need permission from your fiance to buy your own car, a blown up 996 is the least of your problems. Just kidding. It only get worse after your married.
I thought the D-chunk issue was mostly the early model 3.4's and had been sorted out. Man thats depressing. Now Im going to be forced to drop my engine sooner than planned.
I would like to have your car for a rebuild if you decide.
Used 3.6 hover around 6-7K, might be better than taking a huge loss on the thing.
First 3.6L D chunk I've heard of. Could be an early casting process or something (02?)
The Idea of a used motor scares me since I have no clue as to maintenance or condition of the motor, I could just be asking for problems once it is installed. Plus for the same money I can have the motor resleeved to OE spec, of an extra $2000 have it built to a 3.8L. Either way I am pretty set on dumping the car and looking for a GT3, if I fix it, I fix it to keep it and fix everything right. which I cant really justify
Really? add another to list. In my case it was a valve seat that failed and created the d chunk, or so i was told. Only way to tell is it start tearing the motor apart.
Well you can buy it if you want, but I am not giving it away, make a fair offer and I could be inclined.
PS: small things like keeping the fiance happy keep me happy and ends up cheaper in the long run
I am 99% positive it is a D-Chunk. after pulling the plug I had coolant flowing out of the spark plug tube. I lost almost 2 liters in under 5 minutes without cranking over the motor to move coolant or create pressure in the system. I figure losing that much is more than just a head gasket. It could be a bad head as well though. My Boroscope is pretty ****ty, but when put into the cylinder it looked a lot like a chunk missing (could be bad lighting or scaring of some sort but D chunk offers best explanation imo)
I dont really care what happened to cause it at this point since either way the motor is toast and I need a new one
Jordan, the LN 3.8 is a good option. Hell the car isnt worth much without the motor. If you drop $ to upgrade you will end up spending 13-15,000+ if your heads are still good. But, you will have the torque of a 3.8 with nikasil cylinders, forged pistons and 0 miles (abbreviating the process here). I felt it was worth the investment when mine quit. Now if I could write it off and buy a 997 GT3 immediately as opposed to waiting 4 months for the 3.8 rebuild then id go GT3 ofcourse.
Take your time and evaluate all your options.
Sorry to hear that Jordan
You guys need to stop posting depressing stories. KK is gona have a heart attack one of these days.
sorry KK couldn't help myself
If you dont mind can you give us the selling price so we will all know what ballpark we are in if we have the same issue?
Im thinking of turning mine into a household artifact.
Pretty Much, but I was lucky to find the right buyer who had a Black 996TT in a serious front end collision that could transfer over a lot of the parts, actually he may have even got a good deal considering what he would have had to pay trying to source out everything he needs.
02 in my signature... Why?
OP good work selling the car so fast. What Details are you looking for in a GT3? Track ready or daily? I'm about a year away fom a .2 gt3 or .1 RS.
I dont know whether I am looking for a 997.1 or 997.2, I am more concerned with it being properly optioned. It has to be Carrera white, with black full leather package (aka leather pillars, dash etc.) Also needs adaptive sport seats. Needs Chrono Package, but would prefer Chrono Plus package and nav. Needs Ceramic Comp Brakes and bi xenon headlamps. I would like Carbon trim packages and red seat belts but that can be easily changed. Biggest thing is it must be a Canadian Market car, I hate having the MPH cluster and temperature controls in Ferenheit.
I know this is pretty picky looking for a used car, but I will wait for the right one, and when I come across it, I will have no problem buying it without any regrets.
As far as daily or track prepped it wont be my daily anymore, but will see most of its time on the road, not the track. It may see 3 to 6 track days a year, about what I get with my civic now. Basically the lest modified and molested the better, so I can do that myself.
As is, 8-10k max after many months.
With used 3.6, 20k, sell in a few weeks.
I've seen used, running m96 engines as low as 4k (running not reman mind you). That's your best bet IMHO.
Been sold for about a week now, got 10 for it. If I was going to fix it, I would be fixing it to keep it which I couldnt justify after getting bit by the GT3 bug
