Volvo s40 1600 petrol reg 2001 - new head gasket and timing belt fitted (vvt model)didn't realise you should go past timing marks and come back 1/4 turn ! engine runs but very hard to start and somtimes cuts out when returning to idle..... low compression on all cylinders - tea spoon of oil down spark plug hole raises cylinder 1 and 2 to correct compresion but does not help 3 and 4. started first time before over heating, not sure were to go with it. could this be a fault because oil pump not in correct position ? can any one suggest any idea ? or a way of making a tool for locking camshafts so i can prove to my self they are set correct....

SOURCE: VOLVO S40 VVT VALVE

Very easy to swap the vvt valve,but that will not guarantee to rectify the problem,more than likely it will be the vvt pulley/timing unit,this will involve the timing belt coming off.
The vvt valve is located under the upper timing cover,remove the cover and you will see the valve situated on top of the head,undo the connector and remove the 4 bolts and the valve will come off,alittle bit of oil will come out on removal.
remove gasket and ensure the area is clean.
Re-fitting is opposite procedure,ensure a new gasket is fitted.
Hope this helps

SOURCE: how do you align the camshaft & crankshaft timing marks 1.9

This is the same as a Ford Escort 1.9, the #1 cylinder should be all the way up. To confirm- the crak shift mark should be on zero which is Crank Shift Center- THe camshift sproket should align with the headmark. Make sure both marks don't move. Align the belt- not too tight , not to loose

Sometimes you must install the timing cover temporarily with the crank pulley to ensure you are at true Top Dead Center line up the notch on the pulley with the pointer on the timing belt cover or pointer on crankshaft cover I had a problem with a dual cam Honda in which the marks on the engine block where slightly off. you must ensure that both intake valves and exhaust valves are shut one cylinder #1 by turning the cams in the appropriate direction, from your description of the situation it sounds like when it runs poorley it is off by one tooth, when you move forward a tooth it runs but poorly make sure you are moving both cams if equipped with dual cam, both cams should be in the exact same visual location in other words all valves completly shut, be careful not to move lower shaft after lining up the crank pulley to cover pointer marks, after resetting turn the engine over two full turns then recheck all markers.

Code is for the VVT or variable valve timing. Was the timing belt replaced recently. If so the timing belt is not on correctly. If it just happened it could be the valve it self, wiring to the valve/corrosion on connectors. Check the oil level as low oil could be an issue. If the belt was not changed recently try changing the oil and adding a qt of Rislone to the oil. It is designed to free up sticky lifters and could free up the VVT solenoid. Worth a try.

My timing belt broke. need spectes for head gasket, if need to use new head bolts. with a new/used head from a wreck car.also need timing marks for t-belt 1.5l


It probably will also need new pistons as the valves bent and broke causing holes in pistons. If you are lucky and just need a used head go here:http://www.youtube.com/watch?v=LM8j-uHsNhY

Does the 2006 Volvo S40 1.8L petrol have cam belts or timing chain?


This model has one belt for the cam drive system, along with an oil-filled pretensioner. Additionally, these models have VVT (Variable Valve Timing) which consists of a PWM (Pulse Width Modulated) valve and associated plumbing to the hydraulic tappets. This system increases or decreases the amount of TDC overlap (cam timing) based on driving conditions resulting in enhanced performance and lowered emissions. The caveat is that one must be diligent about oil changes and usage of the proper weight oil to avoid clogging of the oil feeds to the tappets.

Timing belt snapped


hi from uk the cambelt timing marks for accent 1.3/1.5 petrol are as follows= the cam cog has a hole drilling between the outer toothed and the central securing bolt this hole at TDC number 1 cyl is at top central and lines up with a V cut in the cyl head at rear of cog ? the crank cog at TDC number 1 cyl is a pop mark on both the cog and on thefront face of engine quite noticable ! these line up and are at approx 12 -30 pm when viewed fit new belt from crankcog in anticlockwise ie crank then cam then tensioner HOWEVER! if you are considering just replacing belt and tensioner ? be warned this engine is an interferance engine that is to say if belt fails whilst driving there may/will most probably be damage to the valves (bent) due to contact with pistons so would advise caution and suggest compression test all cyls after fitting new belt and tensioner and before rebuild completely once valves have bent they will not contact pistons again but you will have serious missfire/s and probably back fire up inlet manifold coupled with failing to start if engine is high milage ? consider removal of cyl head and check? de coke and replace damaged or best all valves then engine will have improved performance and more milesin future hope this helps

2001 volvo s40 trouble code P0015


This is a common issue particularly with vehicles that have had some neglect to the oil change routine. The VVT solenoid on the top of the valve cover gets clogged with thickened or sludged oil.

Replace the VVT solenoid and gasket with a new unit and clear the codes.
