2003 passat timming chain tensioner went bad I went to load it on dolly an it die an wounlden start back so I fixed the tensioner problem an still want start cranks over but no start

Hi. It could be the cam adjuster or the Timing chain stretched.

place no 1 piston at TDC compression stroke. There are procedures for the timing of the balance shafts but if it is only the timing chain I will go to that
Align uniquely coloured chain link with intake camshaft sprocket timing mark-- INT--. ( this will be pointing at the 2 o'clock position)
install timing chain and sprocket as an assembly
align first matching coloured chain link crankshaft timing mark (5 o'clock position)
align the second matching coloured chain link with exhaust cam shaft timing mark--EXH ( at the 11 o'clock position
There is a special procedure to reset the balance tensioner and it is different to the timing chain procedure.

To reset cam shaft timing chain tensioner push piston fully and turn clockwise until locked
Once the tensioner has been compressed ensure the distance from end to end is 2.83 inches . If not repeat the resetting process
vehicles 30.000 miles the tensioner is released when the engine is first started . In vehicles over 30.000 miles manually release tensioner by tapping the plunger
Note cam shaft and crank shaft sprockets bolts MUST only be used once. If you want details on the balancer chain procedure then make a comment in the box
use tension wrench and a degree gauge
cam bolts are tensioned to 63 ft lbs + 30 degrees
crank shaft pulley is tensioned to 74 ft lbs + 75 degrees

Hi, depending on engine fitted it is most likely the cam chain tensioner has collaped or failed. On a twin cam engine like a 1.8 t or a 32 valve V6 there is a chain driving a second chain in the rear of the cylinder head. These chains are tensioned by a oil pressure pressurized piston pushing on a bridge under the chain.

If it collapses, the chain/s become very loose and you will hear a loud clacking noise. It can also collapse due to low oil pressure.

VW is familiar with this problem and the repair involves first checking oil pressure, cold thro' warm. If it is around 85 to105 psi cold and 28 to 35 psi warm at idle, then this indicates tensioner piston is faulty or tensioner guide has broken off.

If oil presssure is good and engine is running synthetic oil...as it should ...then tensioneris suspect. I have also seen these engines with the screen under the tensioner partly blocked . If on removal of valve cover prooves tensioner has collapsed or guide shoe broken or warn then a new tensioner must be installed.

If oil pressure is too low at under 12 psi at warm idle then oil pump is worn and/or engine is worn. Also low oil pressure can be caused by fuel in the oil making it very thin.

If the screen under the tensioner is partly plugged up, then the oil pan must also be removed and cleaned out otherwise plugging will happen again.

To remove and install the tensioner a SST ( Special Service Tool.) is required to compresse the tensioner piston to allow it to be removed from under the cam chain and again compressing the new tensioner to be installed. Cams or chain do not need removing on this job.

Most import shops can handle this as long as they are equipped with the SST tensioner tool.

if you have two guides check and see if you got them on the right sides

check ur batt cables to make sure they havent went bad.. and if thats not the case ur starter is prolly out

The timing chain? You mean the one inside the head that drives the intake cam from the exhaust cam? Or do you mean the timing BELT and tensioner, that time the cams relative to the crank?

P0011 means the timing is over-advanced (if you were doing timing belt/chain work, it's probably not on correctly and one of the cams is advanced relative to the other one, or the cams are advanced relative to the crank). If that's the case, the solution means tearing it back apart and timing it again.

1st check the the oil level and the vehicle's oil type.(owners manuel) 5w30-10w30
10w 30 is a thicker oil and could possibly be causing this.(Moves more freely through the engine heats the oil)

TIMING BELT SHOULD BE 60,000 MILE CHANGE

Replace the timming chain, gears, and magnet. With that cat getting that hot it has to be out of time. When the cam sensor picks up no signal, ecu can't control timming and reverts back to a preset,fixed base # .

the noise is the chain tensioner in the cylinder head between the two camshafts. it is a job for a proffesional shop. the 1.8t passats had an oiling problem and were fixed with a larger oil filter. some times you have to remove the oilpan and replace the oil pickup tube.
