  1. dporto: I agree, I definitely dodged a big bullet on this one...
  2. I thought I would share the final result of my chase of the P0344 OBDII code. I believe the root cause was the failed chain tensioner on Bank 1. I'm still a bit confused how the exhaust timing on Bank 1 could be in line while the intake timing on Bank 1 would up retarded. Given the rotation of the chain is clockwise, that means the chain would have to jump opposite rotation which I can only theorize was due to a backfire during start up but that's only a guess. I replaced all 3 chain tensioners, retimed bank 1(bank 2 timing was spot on) and reinstalled the engine. While the engine was out
  3. I removed the engine and started looking into why the intake cam was retarded. See photo of what came out in my hand when I removed the chain tensioner for the left bank. I'm assuming the slack in the chain resulted in skipping a tooth or two on the intake cam only as a result of the chain tensioner failure. I'm wondering if I should also replace the variocam + sprocket. I think I will replace all 3 tensioners in the process of re-timing the engine. Any thoughts or theories in how this tensioner failure could lead to the exhaust cam remaining in proper time while leaving the intake cam in
  4. I'm preparing to remove the engine and thought I would check the cam time one last time. I bought the tools for setting up the timing and set the crank up at TDC per the Bentley manual. The tool lined up fine on the exhaust cam but would not line up with the intake cam on Bank 1. I tilted the tool and took a photo of it when it lined up with the slot in the intake cam. Photo is attached. Is this consistent with a reluctor loose from the camshaft? Could this have been caused by a chain jumping a tooth due to a bad tensioner and/or a backfire on start up? It seems that I will definitely n
  5. JFP, your point is well taken but to inspect the cam rotor I will have to remove the engine. I'm trying to resolve the issue without removing the engine. I will be doing this work at home in my garage without a hoist and engine removal won't be an easy chore. If I can check the valve timing without removing the engine, I am willing to try this first. Thanks for your help and comments.
  6. Since my last post I have been trying to resolve this reoccurring PO344 code by eliminating the relatively simple things that may be related to an intermittent circuit for Bank 1 cam position as well as performing other maintenance. I replaced both cats, replaced the spark plugs (52K miles on car so probably due), replaced the Bank 1 cam sensor, replaced the Bank 1 variocam timing solenoid, cleaned all wiring connections between the cam sensor and the DME with "deoxit", ran temporary wires between the DME and the cam sensor. Nothing has changed still getting P0344 code. I have not purchased
  7. Ahsai, unfortunately I do not have a Durametric. I may try replacing the cam sensor and installing new catalytic converters and starting the engine to see if the code comes back.
  8. Ahsai & Loren: I removed the bank 1 cam sensor on the left rear of the engine. I was able to get the tip of my little finger into the hole and feel the reluctor to learn if it was loose from the camshaft. The best I could tell it was not loose. I noticed that the wiring connector (male portion) and the speed sensor (female part wiring connector) were quite wet with engine oil. Could the sensor be bad with oil leaking into the wiring connections causing an intermittent/open connection? It appears that the intake cam is slightly retarded, will the VarioCam chain sprocket on the intake
  9. Loren, how do I do that remove the LH valve cover and inspect it? It's on the opposite end from the flywheel on Bank 1 correct?
  10. I'm recently acquired a 2003 Carrera Targa w/3.6L 3 chain engine. Both catalytic converters had honeycomb guts rattling so it was hard to hear anything but the bad cats. I'm getting a reoccurring P0344 code and am concerned with an IMS bearing on it's way out, car still runs OK but not driving it until I figure out what the problem is. I removed both cats and the driver's side muffler, set the engine up on TDC #1 and pulled the cam plugs on the left side. The exhaust cam slot seems to line up properly but the intake cam appears to be rotated counter clockwise about 1/2 the width of the slo
