We had a CEL on a 2004 996 with a error code "Check camshaft timming or Variocam".

Suggestion
I think I'd rather change the lifters than the water pump.

Suggestion
For me, it was a $700 or so part and a bunch more in labor to R&R the part and reset timing etc.

The engine was misfiring at low rpm, run perfect at high rpm.
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.

We had a CEL on a 2004 996 with a error code "Check camshaft timming or Variocam". It appeared to be a stuck variocam lifter on cilinder number 4. Anyone ever heard of such a fault?
I saw a 997 with that fault today at the dealer. the lifter could not be adjusted. it was fine at high rpm but at low rpm it had a few misfire errors.
sorry to say the engine was out of the car and there was a lot of parts on the table.
It's good to hear they actually opened up the top end! 5 years ago that would have been "ship it back for a replacement motor" and wound up on the internet as an "engine failure"
I had a similar failure on my Boxster. Mine was a broken "variocam actuator". CEL came on. ABout 100 miles later it wouldn't idle. Has a failsafe position to prevent catastrophic failure. For me, it was a $700 or so part and a bunch more in labor to R&R the part and reset timing etc.
Just for informational purposes my car is in the shop today with a #6 bad lifter. Low rpm position not working and CEL Remove top of head and replace all right side lifters is Porsche's strong recomendation so here we go. Also needs a water pump...Happy New Year!
Almost ruined a great day as my 1 1/2 year race car project is getting painted finally......Nope, still a great day
Steve, ****, no wonder you offered to sell me your car last Saturday!!! Just kidding.
Sorry to hear about he lifters and the water pump.
Can't wait to see the race car! You did have it painted blue, right???
Oh yeah, it was Sunday!
Well, to be honest, I am really glad I was only one day off. When you don't have a job, every day is "today," yesterday never happened and tomorrow doesn't exist. However, I still remember the 7 days of the week; Dopey, Sleepy, Sneezy, Happy, Grumpy, Bashful, and Doc. Let me double check 1... 2... 3... yup, got all 7!
I think I'd rather change the lifters than the water pump. That was a serious PITA. The shade tree came out me and I had about a 4 ft long tamping bar wedged between the motor plate and the engine to gain clearance. But, maybe it was because mine was a Tiptronic? Never messed with a manual car.
Anyways, sorry to hear Steven...that is some major work.......
Yes Cory, you are braver than me trying the water pump as mine is a tip also. Window regulators, brakes, headlight switches and serpentine belt is my limit.
