Hello, My name is XXXXX XXXXX X am a Volvo dealership technician. I am going to try to help you with your question. First of all, you have three totally separate questions in one. This category is for Volvo experts, so I can only address the Volvo question. Second, I see you previously asked about the Volvo, told the expert you got an answer from a friend and never accepted his answer. What information did you receive from a friend and what information do you currently need?
I needed info on timing belt and no start. So called expert jumpedto conclusion that the valves are bent without any diagnostic. I called afriend and he did a compression test and all were okay. What I need now asstated.
How did he do a compression test if the belt wasn't on?
Placed the belt, removed the sparkplugs and used a gage. Thecan runs good with little hesitation. I need help on above not what was done.
I am sensing you don't trust the experts here much and customer service has emailed me saying you need answers soon. I have the procedure on my home PC but will not be home until an hour from now. If another expert would like to help, they will be along. Good luck
an hour will be great. i do not trust the first so called expert. when somebody claims they are an expert then they need to follow procedure not jumb to conclutions out of bieng lazy
Okay, here is the procedure for the cam seals, timing belt and CVVT hub set up. Note that you will need a special tool set to properly do this job, which you can buy here. That is the only way to do it and that is the proper procedure. Please remember to rate the service when you are done. You are a subscription customer so it does not cost you anything additional but it does ensure I am credited for helping. Let me know if you have any other questions
is the camshaft pully pressed on the camshaft.
No, neither of them are. One is just held on with three screws. The other has a plug to access the bolt
I replaced couple of camshaft seals in the past (older cars) and all I had to do is take the camshaft pully out and pry the seal out and replace. the tool on Ebay is recommended for R&R cylinder head. Can i remove the camshaft pully and pry the seal out and install the new seal!!
You can remove the seal and put a new one in. But the tool is needed for installing the camshaft pulley and making sure everything is aligned, as well as making sure it stays in place when tightening the CVVT pulley.
I understand you need the tool when tightening the ccvt pulley so it does not bent the valves. if I turn the crank so it does not hit the valves then would i be okay?
my other concern when I remove all the spark plugs and turn the crank shaft and place a rod were the spark plug to ensure #1 timing. When I removed all spark plugs and turned the crankshaft I had two cylinders same hit and the other two same hit. is that how this engine is designed?
You need the tool to make sure the cams and crank are all perfectly aligned.
The engine is not timed based on TDC of any particular cylinder. It is timed when the tool is installed pinning the crankshaft and holding the cams. That is the proper procedure.
Super. now the crankshaft has two small marking on the pulley ans two marking on the housing, which marking on the housing I need to alighn the two small marks on the crankshaft pulley facing the engine!
The two small marks on the pulley go on either side of the notch on the crank. When the tool is pinning the crank, it is in the correct position.
can u email me a picture showing the marks on the crankshaft and housing please.
This is from a 5 cylinder, but I believe it is the same on yours. Is the balancer removed? Can you send a picture of the marks you have?
I removed the camshaft pulley and replaced the cam seal. their is another donut seal on the back of the camshaft pulley. did u know that? do I have to change that too?
Yes, you can replace the rear cam seals as well. You don't have to replace them if they aren't leaking, as they can be replaced later without having to re-time the engine. Please remember to rate the service so I can receive credit for my answers. You are a subscription customer so there is no extra charge to you and you can still follow up any time.

Andy after replacing both camshaft seals the car does not start. I believe one of the cams moved. how can I make sure the marks on each cam is accurate
As I said, you need to use the special tool to properly do this job. I assume you tried to do it without the tools to hold the cams and crank in the correct position?
yes. I marked both camshaft and screwed up.
any marks on the back of the camshaft!
Marking the camshafts is not the same as using the special tool. If you use the tool correctly, according to the procedure I sent, there is no way to mess up the timing. It locks the camshafts in an exact position and locks the crankshaft in an exact position. You NEED to use the tool. There are no marks on the back of the cams, because when using the tool, marks are not needed.
How Can I get the camshaft timing right?
As I have said multiple times, the ONLY way is with the special tool. There is no other option.
any ideas on cam alighment with the crank
I am not sure where the confusion is here. The ONLY way to time the engine is with the special tool. There is nothing else I can say except keep repeating that.
I understand what you are saying but my issue is more than what we think. my issue is that I removed the camshaft pulleys without the tool to replace the camshaft seal. When I lossened the screw on VVT pulley the camshaft moved and the pulley did not, so the mark on the pulley and back cover does not mean anything. same issue with intake pulley, removed the three screws and the camshaft moved while the pulley is out of the car. I need to know how I can ensure the pulley mark match the back cover. is there any other marks that I can rotate the pulley on the camshaft to make sure the mark on the camshaft alighned with back cover? Andy the real question is if the pulley was removed from the camshaft and re-installed in any order would the mark on the pulley and the back cover always work?
The tool to replace the seal has nothing to do with this. There are no other marks- you need to lock the cams and the crank and then set the marks, just like the procedure says.
You will need to buy the tool. Remove the starter and insert the crank pin. Turn the crankshaft counterclockwise until it stops against the pin. Then the slots on the backs of the cams need to be horizontal, with the one on the intake cam being slightly above center and the one on the exhaust cam slightly below center. Then the cam locking tool is installled and the pulleys are set up according to the instructions. This is the ONLY way. I see questions like this on here a lot and I have had several towed in because someone tried to do this job without the tool.
I will order the tool.
Just to clarify that it does not matter if the camshaft pulleys moved around the camshaft and the camshaft mark is in different position that what it was I will still be able to align the camshaft on the back if both camshaft are horizontal and the mark on each camshaft corresponds to early instructions. I need a picture on using the crankshaft pin and an easy way to remove the starter. When I turned both camshaft pulleys five teeth to the right (the mark on both camshafts were of to the right by five teeth) the engine started and ran great expect little shake.
Also I replaced the camshaft seal on the exhaust side and it looks like it still leaking, do I have to change the pulley?
You shouldn't have to replace the pulley unless it is damaged.
The instructions show a picture of the pin for the crank. Once the starter is removed, you will see a plug with an allen head. Remove the plug and put the pin into the hole. Then turn the crank counterclockwise until it hits the pin and follow the rest of the instructions
Andy i need your help on the oil leak from exh cam and splashing all over. i replaced the cam seal but it looks like the oil is coming from the cam pulley.
From behind the pulley?
