Hi All, recently I changed the Cam oil seal, timing belt, tensioner and idle pulley. I marked all timing and then tightened the T55 bolt (on the intake cam hub), then I started the car and it ran well. After 30 minutes to clean up tools and everything I restarted the car again but this time it took few more seconds to start ... I drove the car for about 1 km and returned home. Next morning I started the car again but it struggled to start and it was also shaking ... then stalled.

I believe I screwed up the timing by "not tightening the T55 bolt at the specified 88ft/lbs, hence the camshaft slipped/turned without back to the correct position. I hope I did not bend the valves. What I am planning to do is to readjust the camshaft in the correct position, get a cam locking tool to lock the intake camshaft and readjust the timing again.

My question to you is that if I open the "cover" at the rear of the camshaft, how can I know if the cam groves should be level with the engine head and the valve cover ... also I saw some pictures on web site showing there is notch ... how can I put the camshaft to be back to factory setting? Appreciate if anyone knows and any suggestions? Thanks

You need to lock the camshafts with the right tool for a start.
Due to there being no keyways on the cam gears you need to follow the factory procedure for setting up the vvti pulleys.
Also the 4 cylinder cams kick back more so than the 5cyl so there's little chance you could hold the cam in the correct place whilst tightening it to the correct torque.
Thanks Tim, yes I will get the tool. but the situation is that the crankshaft already turned .. I don't know how to put it back to align the correct position. I will open the rear cover where the position sensor housing is to see how much it is out. Yes I read the procedure already but I did not before the job.
Correction: cam shaft not crank shaft
The locking tool secures both camshafts together at the rear in the correct position so you just align the crank with the mark and you're good to go.
You then need to setup the vvti pulleys to specs
Thanks Tim. As I asked before, how would I know if the intake Cam has moved/turned not aligning the correct position. Is the cam grove (see from the rear) horizontal or vertical? As there is NO reference to the camshaft, it is difficult to align.
If you’re in Sydney I’ve got the tool you can borrow. Just bought it to fix my xc90.
Well, Marty this is great! Yes I live in Epping ... only 10 minutes away. My mobile is 0438557579.
Cam groove should be horizontal. The tool only fits in one position. It will make more sense once you see the tool itself
Thanks Tim Marty just call me ... will pick up the tool will work on it next week.
a month later
Thank you Marty for lending the tool to me, I have successfully done the job. The intake cam was found to be out approximate 4 mm, also the crank timing mark was also not 100% aligned. Now the car has been brought alive again, the service light and engine check light have been cleared by itself.
Thanks Tim for your advice too.
