Researching my issue the past few days, reading a lot about ANY timing belt slip means your engine is toast? I'm hoping Rick is correct though! I do see what I would consider significant play (1/2"-3/4") in the belt when its pressed as seen in the attached image. The hydraulic tensioner (cylinder/plunger) also moves quite easy when force is applied. I know form experience how difficult it is to compress the tensioner cylinder/plunger with a clamp.

If it is the tensioner, I'm seeing a new tensioners at IPD (MTC) for $40 and $95-$110 at FCP? Understanding OE vs OEM.

Tensioner is definitely bad from your description. A few teeth of slippage is not engine death (bent valves), but several teeth is.

The factory tensioner is Aisin, I wouldn't touch MTC unless you are OK losing the engine at some point.

Belt breaking is toast. Slipping has some forgiveness.


For mission critical components, use OEM parts.

OEM Part numbers:
  • Volvo 9146693
    Asin BTV-005
    Febi 22143 (Repackaged Asin)
You can find these for ~$60.00 but if you get the one from FCP, replacements from them on will have a summed cost equal to the cost of shipping the old part back. FCP Euro lifetime replacement guarantee.

I purchased my T5 from a good friend along with a detailed 8 year mechanical history excel report. He also completed all the repairs like me. Fortunately, the tensioner and timing belt were purchased from FCP and covered under lifetime warranty! Ordering both today. Going to align the cams/crank to see how many teeth were jumped.

The warranty doesn’t transfer so you will have to pay for the parts. It’s unfair to the vendor to cheat them on this deal, so have him do the repair before you transfer the title. Keep it clean so they keep doing this deal.
