Troubleshooting help

[Tuner1984]

I've had intermittent issues lately with the camshaft lifters not lifting properly.  I've changed the camshaft position sensor, checked the solenoid bracket on the valve adjuster, and now will be swapping out the actuator on bank 2.  If this doesn't work any other ideas?  I'm hoping it's not a camshaft sprocket failure, but with it being intermittent I'm more leaning towards a sensor of some sort.

 

Car is a 2002 6 speed 996 TT.  The code that comes up on the durametric is P1358 Camshaft adjustment bank 2 below limit.

 

Thanks Guys!!

Your doing all the troubleshooting that can be done. You are well aware of all the possible failures!  I help a member in 2008 with almost the same issue P1325, we work hard on that one . Unfortunately he sold the car before a fix ;-(  May be you can found some help here: https://www.renntech.org/forums/topic/24113-obd2-fault-code-p1325-inlet-camshaft-bank-2/#comment-127060

This is what you don't want and it is related with camshaft housing grooves ;-( http://www.rennsportkc.com/996tt-top-end/

Just realized you are the new member. Welcome to Renntech community!!! You got a heavily modified car, did you ever suspect the ECU reprogramming?

Thanks!  I'm 100 percent confident it is not the tune.

You may already know this:

 

P1358

Camshaft Adjustment, Bank 2– Below Limit

Possible fault cause

Solenoid hydraulic valve is triggered, camshaft does not switch into

early position

♦ Dirt in system

♦ Solenoid hydraulic valve mechanically blocked

So horrible news when I swapped the actuator.  I found some metal and when I tore into the oil filter there were metal shavings.  Kind of at a loss on this one.........

 

I've only owned the car 9 months and have changed the oil 4 times and until yesterday found no metal shavings or anything.  I am the 3rd owner of the car and this is mainly a weekend/nice day car.  I've never tracked the car.  I did some research and also went through the links Jpflip provided and only thing I can think of is, is maybe somehow a camshaft ring maybe broke, but I don't know.

 

At this point I think I'm probably going to get rid of the car and look for another Pcar.  I don't have time unfortunately to pull the motor apart for further troubleshooting.

Just maybe wanted to get some advice on price point for my car.

I bought the car about 9 months ago.  Car currently has 54300 miles, Artic Silver, Grey interior, 6 speed manual, with the carbon package, factory areo kit, and the Porsche crests in the headrests. 

I've recently been having issues with an intermittent error P1358 error code (Camshaft adjustment bank 2 below point.  I've swapped the camshaft position sensor, the actuator on bank 2, and checked the valve adjuster bracket.  None of that worked.  I haven't gotten down to try the following troubleshooting steps to alleviate the issue:

P1358
Camshaft Adjustment, Bank 2– Below Limit
Possible fault cause
Solenoid hydraulic valve is triggered, camshaft does not switch into
early position
♦ Dirt in system
♦ Solenoid hydraulic valve mechanically blocked

When I swapped camshaft actuators on bank 2 I discovered a little bit of metal.  I cut into the oil filter and found some more.  I haven't flushed the system yet as I am not sure what I am going to do.  There's no rod knock and I'm thinking maybe a camshaft ring broke that dropped some metal.

Car has new center radiator, spark plugs, 997.1 coil packs, new camshaft position sensor, new camshaft actuator on bank 2, brand new water pump, thermostat, and drive belt, new pads and rotors.

The car has 71lb RC Fuel injectors currently spraying at a 60lb rate, fabspeed exhaust, fabspeed headers, competition plenum, evoms intake, and custom dyno tune, gt2 slave conversion and clutch, gt3 shifter.

Interior for the car for it being 15 years I'd rate it 8/10 and body 8/10.

So with the above mentioned what could I start at price point wise?  Is 30k obo reasonable?  Thanks.

I realize the last post on your thread was in June but was wondering what you ended-up doing with your car.
