did a timing belt on a xc90 t6 everything went well, expect that coolant valve/t-stat and getting the belt over the tensioner. I found what I thought to be the marks at the crank pulley and they lined up with the timing cover 12 O clock marks, nothing really even moved.

Started it up ran fine. idle's good. doesn't really lack power, didn't really get on it before so not sure how fast this thing really is. so anyway while in park bleeding coolant reving to 2.5-3K the MIL starts flashing. P0300, p0301, p0302. swapped coils, nothing. swapped plugs, nothing. put in stardard plugs nothing. so I'm rechecking my timing.

I'm looking at service lit. and there's no timing mark where there showing. nothing on that dampner nor the pully. I see 1 mark on the engine and the crank gear. and that mark lines up with the cam's on the timing mark. I even have the cam locking tool and with the cam's locked everything is set.

Now what's interesting is that If I put a screwdriver in plug hole #1 and set TDC my marks are way off.?????????????

so I'm trying to get an actual picture or something of the timing marks to verify my work. I'm not finding anything on the 2.9 t6.


Thanks.

 

Any luck with this? I'm having the same issue. And yeah, same thing I found #1 at TDC gives you timing marks way off.

 

Aligned timing marks is not TDC. Have you guys checked other model Volvos like S80's which would have the same motor? Also try Google, www.SwedeSpeed.com and www.MatthewsVolvoSite.com.
