Can I actuate the valve adjuster with the engine not running? Thanks in advance. I know the measurement between the intake gear mark and bridge are slightly off its making me think the cam adjuster is stuck. The last bearing on the oil bridge that supports the end of the exhaust cam looked good and was not scored. I replaced an engine recently in a GTI that had a CCTA engine and the cams were nearly seized into the head from lack of oil. I have installed the updated tensioners and retimed a few of these now in the past month but haven't run into this issue yet. Should I pull the pan off and inspect the oil pickup tube? Could the chain be stretched? Could the fluted actuator be jammed up? I found a VW self study program #246 it says "If the vvt fails to function the fluted variator will be pressed by the oil pressure to the basic position of 25 ATDC". I have too much time involved already and the car still doesn't run right. Reinstalled after inspection and car runs the same.Īny ideas what might be going on with this engine? The owner is already crying about the initial cost of repair. I also removed the aluminum bridge between the cams to inspect the screen and make sure nothing was plugged up and that looks good. All blocks except 1 RPM, stay constant even with increased RPM. Group 91 block two is 5.9, three 28'kw, four 28'kw. After looking at the problem car again I realized that the cam adjuster is not functioning at all. I have another car in the shop that is identical year and model so I looked at group 91 in the engine controller and made note of how the cam adjuster functions with relation to the data blocks. This makes me think the car doesn't recognize the correlation problem until the ECU is in closed loop. The car runs for about five minutes without throwing the cam correlation code. So I took the top cover off and measured again. I noticed the correlation code had come back. After running the car for a few minutes and trying different things. I also blocked off the oil/air separator to get that out of the equation. I have swapped out the plugs and coils with known good parts as well as the cam sensor. Once the car started up it immediately started to misfire but no correlation code. I contributed this to the tensioner not having been pressurized so I cranked it over with the upper timing cover off and that stopped once it had oil pressure. I noticed with the upper cover off the cam chain wanted to jump off the sprockets when the engine was turned over by hand. I installed the new tensioner and retimed both chains. The center deflector was almost cut in half. Once removed, I noticed the oil deflector on the inside of the cover was making contact with the chain in two different places. I decided to remove the lower timing cover and install the latest chain tensioner with the K suffix and a new cover. One time it was a quart low and the other time it didn't require oil. According to the customer oil was checked both times the light came on. It was 25psi at idle and increased as I rev'd it up so that appeared acceptable. The customer said the oil light came a few times in the past week just before the car started having problems so I hooked up the oil pressure gauge. I checked for bent valves with a leak down gauge then did a compression test. The distance between the bridge and the intake mark was slightly under spec by a few mm it measured about 59-60 mm. I used DrPeter's quick reference procedure and measured the distance between the cam sprockets with the engine at TDC. Car has cam correlation code p0016 and abnormal chain noise and misfire codes on all cylinders. ![]()
