99 s80 t6,2.8replaced timing belt and cam seals(leaking)has varible timing,the exhust cam turned when l loosened the bolt,dont have the volvo alignment tool,with the marks aligned,are the slots on the end of the cams where you would install the alignment tool,straight across with the tool installed or pointed at angle toward the center like it show for head insallation?thanks for any help.

 

Usually it is straight across.
But did you mark the VVt pulley before removing it?
If not you will need to somehow lock the cams and go through a special presidure to get the VVT pulley set right.

 

befor l took it apart l lined the timing marks up on the pulleys,l have those lined up now,and the exhust center bolt loose,to adjust,the rear of the cams,the slots are a slightly downward angle to the center,lpulled the plug out of the block and went thru the precedure to make it is at tdc,so with all the should l turn the cams slightly to make the slots line up straight across to each other?thanks

 

You should have lined the mark up before removing the belt first and marked.
Then you should have removed the belt and turned the pulley foward and marked it.
Then you should have turned it back and marked it.

The pulley has to be set in a certain position. Some need to be loaded and others just need to be set in a certain position. It all depends on which Cam the VVT pulley is on.

If needs be I can try to post the Volvo precidure so you can try it.

 

the pulley is on the exhust cam,had all the marks lined before l took the belt off,as soon as l broke the retainer bolt loose for the vvt pulley it moved,not sure which direction,the intake cam seems like it stayed where it was.thanks

 

Yes but did you make 3 marks on the Cam cover for the VVT pulley?
If not you WILL need to lock the cams and do the full precidure.
The pulley when locked down moves about3 to 4 teethof a turn or a little less each way.

 

so the pulley need to be centered in its traval,with the slots straight accross.

 

I will have to check for sure. I forget it the Exhaust is the spring loaded one or the one that moves free.
I think it is the spring loaded if it is then no it needs to be turned almost all the way foward. It should stop like 1/16 of an inch after the timing mark. Then when you install the belt the mark lines up.

 

l bouhgt the cam tool,have it installed with the cams alighn,on the vvt gear be fore you install the timing belt do turn the vvt clockwise till it starts to become under tension or at the start of it?thanks

 

I believe the Exhaust VVT pulley should have the tension and be fully at the position to the right just after the timing mark. Like half a tooth past the mark to the right when you look from the front.

 

DO YOU HOLD THE PULLEYUNDER TENSION TO THE END OF THE TRAVEL AND THAN INSTALL THE TIMING BELT,WHERE THE GEAR BOLTS TO THE VVT IS SLOTTED,WHEN TIMING MARKS ARE LINED UP,ARE THE THREE BOLTS CLEAR IN THE COUNTER CLOCK WISE POSITION IN THE SLOTS?THANKS FOR ALL YOUR HELP.

 

The 3 bolts should be centered in the pulley.
Yes you will have to hold the tension and install the belt.
This is the special precidure on how it is supposed to be installed look it over. It is a bit confusing.

 

got everything back together,runs fine,thanks for all the help.

 

No problem anytime.

 

spoke to soon,ran fine at first than started loping,can you get the cam sensor ring out,l lined the notches up,cam lock tool lines rt up,crank lines up and went thhru the precedure for vvt,there is a recall on the electronic throttle,could this be doing it ?thanks again.

 

I doubt the recall will cause it.
Is there a check engine light on?
If so what codes?
If it was the throttle body there usually is codes there.

 

when l first put the timing belt on,befor l got the cam tool,l turned it over by hand 2-3 turns,no resistant like it would if it were hitting the valves,could it have tweak a valve?l will get it scanned today an see what it says,somtimes it smoothes out and than starts a loping spell,put you in mind like somthing still out of time,does the vvt play a role in the timing like that?

 

Yes it does but have the codes pulled.
If a generic scanner is used the codes would read something like Manf. Control or something like that.

Believe me if the timing was out there will be a code telling you.

 

believe found the problem,ran compression, and varied 60-155 psi,so l would say the valves hit.

 

Usually if you have a bent vale you would have 0 compression.
Did the timing just in the first place or soemthing like that?
Unless you really cranked it over by hand hard just turning it by hand usually won't bend one.
