Hello all, just joined and my first post here.
Recently bought a non running 2013 Passat TDI . Serpentine belt was thrown off, Battery was drained, then frozen in very cold temps bulging and destroying it. Needless to say I bought it without ability to power it up. Car was cheap enough that it leaves room for cost of replacement Engine if required. There is one available in my area.
Carfax maintenance is sporadic and doesn't show timing belt done, oils changes seemed fairly regular though, car is at 186k Kms.
Figured the Serpentine belt let go, taking out the Timing Belt and wrecking the Valves. But as I disassembled the TB seem intact and tight with good tension. Moror turns freely by hand with socket on Crankshaft.
Looking at the Cam Sprocket, the 3 bolts in the slots were loose enough to allow Sprocket to shift end of slots, throwing out the Cam timing enough for car not to run properly I'm guessing. Also the 3 bolts were quite loose, guessing less than 10 ft/lbs force to loosen them.
I have ordered the Dieselgeek timing tool set but hasn't arrived yet, but with Cranshaft indicator at TDC as best as I can eyeball, it looks like the Cam sprocket pin and HPFP pin holes are very close to lining up. I can't see any damage to TB or debris that would have caused the belt to jump teeth.
Question; Can the sprocket slot movement on the 3 bolts be enough to get valve interference?
