Warped heads and gasket an easy fix, or is it a rabbit hole with several things needing to be replaced?

My guess would be rabbit hole with a lot of tempting upgrade side tunnels.
It's too bad the shop didn't pressure test the coolant system with the engine still out after they pinned the lines.

Engine wasnít taken out for fix. Looks like it will be now so Iíll probably get all the hoses pinned and replace all the vacuum lines etc. Anybody able to offer any idea on what head gasket replacement and if I do have warped heads how much something like that costs to fix?

Atrox, you most likely have at least one head gasket blown.. Do both banks.. I have seen it happen on 3 engines. Make sure your shop surfaces the heads. A engine that I have repaired required new cylinder liners due to the scuffing. The coolant quickly empties from the heads and cylinder water jackets. High temperatures cause these issues.

I have written this before on many of these threads.. Turn the engine off and coast to safety.. If you are in the left lane>>pull over as soon as possible.

Seems like these issues are becoming more frequent with age/miles, not a fun club to be in.. I looked up the reported cases relating to coolant failures on the NHTSA site, found only 39 complaints filed. PCNA responded to the NHTSA back in 2013. Unfortunately, it doesn't appear anything will done to address these failures. Found one section of interest:

14c. Porsche identified the water neck coolant pipes used in the various subject vehicles as the most likely to fail from the observed warranty claims and customer complaints. The water neck component is identified by three different part numbers in each of the three subject vehicle models. The following table identifies the part and applications:Water neck
(connections)Application
Vehicles
Spare Part No.


996 Turbo

996 GT2

996 GT3
MY2001-2005 911 Turbo

MY2002-2005 911 GT2

MY2003-2005 911 GT3
996.106.039.73


997 GT2
MY2008-2011 911 GT2
997.106.039.72


997 GT3
MY2007-2011 911 GT3
997.106.039.90
In each of the water necks, there is a single bonded connection point which is by far the most likely to fail (connections A2, G2 and K2). Porsche believes it is this single common connection point that has leaked in the vast majority of warranty claims and complaints. The reason is that the coolant exits the cylinder head at this location and is likely exposed to the highest temperatures and pressures. When the engine is shut off the system coolant temperature peaks and remains hot for some period at this location as a transfer point for heat from the cylinder head to the water neck. Over time, this particular connection has significantly higher heat exposure than other connections of the water neck.

14d. Based on the number of warranty claims for the subject vehicles we calculate a complaint rate of 1.589% up to the present. Considering the average age of the vehicles in subject group is 9.6 years as of September 10, 2013, and the average age of the vehicle when repaired was 4.2 years, leads us to the conclusion that the failure rate will not increase significantly in the future, For further details please refer to the Excel file in our response to Request No. 16.
14e. Please be aware that Porsche does not recommend repairing any loose or separated fittings involving the subject components. Porsche only recommends that the entire assembly be replaced.
14f. Our instructions to the technicians are to only replace the components that have failed.
14g. Porsche is not aware of any such testing or surveys.
14h. Please refer to our response to 13a.
14i. No such kits are available from Porsche.

Update time:

Turbo was officially totaled out by insurance company and settlement was more than adequate. Parts and labor exceeded value, and with replacement engines that were found all surpassed the current mileage.

Cant say enough how much I enjoyed that car and the itch it scratched. Truly that was the best car Iíve ever owned and enjoyed.

I will be moving on to another 911 and itís either going to be 997.2 tt or 991 gts or C4s. Iím closely looking at the 991ís as they always say get the newest Porsche you can afford. Budget is 100k so any opinions on moving out from a 996tt to another 911 would be greatly appreciated. Iím really digging this one though.

can't imagine a better option than a 997.1 GT3 for 100k. This one actually... https://www.6speedonline.com/forums/...r-tribute.html

The 991 pictured is sweet. I would go for a 991.2 Carrera S with X51 power kit.

What insurance did you have that covered an engine failure?

Same question as Carlo - how does a mechanical failure get totaled, or is it due to the fact that you hit debris that caused the fitting to give out?

I suspect it was the debris. My first 996, a '99 C4 aero, had just had the engine replaced by insurance right before I bought it. The previous owner ran over a tire tread on the highway, which knocked out the oil filter housing, starving the engine of oil. The car had 130,000 miles on it at the time of the "accident". Insurance bought a used engine with only 70k miles.

So, sounds like insurance couldn't find a lower mileage engine for Atrox and just totalled the car. Sweet deal for you, Tyler. Keep us posted on what way you go. Remember, you've only got a few weeks before spring fever hits and prices go up. Honestly, I'm not sure what I'd get. Would be tempted to look at Caymans as they are probably closer to a 996 than a 991 is

I am literally beside myself that a motor going bad totalled out your car? That's truly crazy, and terrible news...unless you're OK with it. I would NOT be OK with that at all for the record, but best wishes to you my friend.

Debris hit the rear under body pretty hard when I drove over it. The fact that there were two fittings that popped loose was a direct result of this coupled with wot. I am insured thru USAA and they have been stellar in handling this claim as well as a more than fair market evaluation to the retail price of the car.

It sucks not having the car as it was my first real toy purchase after years of saving/working. At the end of the day itís just a car and there will be others.


For those on the fence about pinning I canít stress enough how necessary it is, it would have saved my car regardless of the impact. Car had 40,000 miles on it and never been tracked. I only drove it on the weekends and put 12k miles on it in 4 years.
