SOURCE: no compression in one cylinder

Timing belt slipped around cam pulley. Take off your timing belt cover and check the position. This would explain misfiring and compression loss. Stretched belt or missing cogs in belt likely culprit.

SOURCE: 99 Volvo S80 water pump replacement

if this helps.. I had the 1998 model S70. the water pump was driven by the timing belt. you had to take the timing belt off just to replace the water pump. it was just a simple bolt on replacement. the only difficult issue is resetting the hydraulic tensioner on the timing belt. the hydraulic tensioner has to be completely taken off and compressed VERY SLOWLY in a vise. then insert a very hard drill bit or (special volvo tool) into a keeper hole, reinstall hydraulic tensioner onto car and reinstall timing belt.very quickly remove drill bit from keeper hole in tensioner and the tensioner snaps back out to put tension on belt. and you are done.

SOURCE: transmission valve

All I know is that volvo does not replace shift solenoids anymore. I dont even think you can find that part. I used to work for volvo and the manufacturer would have us just replace the transmission. You can get a factory instruction manual from volvo. Its called a first edition manual. They are not cheap. It might be a good idea to bring to the dealer, just find get a second opinion.

Have 4 codes P0306 P1181 P0141 P0136 is there easy fix? Also vibration at high speeds and passenger aide in front sounds like humming any ideas 2000 Volvo S80 2.9 Non turbo


There is no "easy fix" as only 2 of the 4 codes are for the same thing...for the P0136 and P0141, its probably a bad Bank 1 sensor 2 oxygen sensor..the P0306 means cylinder 6 is misfiring (it could be bad spark plug, bad coil, bad injector, carbon on valves, low compression) and P1181 is showing a fuel delivery issue high pressure...as for the vibration, have all tires checked for balance and hum on passenger side is possibly a bad wheel bearing...and and all is best to have checked by your mechanic.

I am trying to find out what the cylinder compression should be on a 2001 volvo s80 2.9L


Hi,
Are you sure it's a 2.9?
The biggest engine I can see is 2.8, if it's that the compressions should be 11-13bar, all within 10% of each other.

Engine losing compression on number 2 hole why?


this could be a number of things, Most would be a bad valve, , it could also be a bad head gasket, or bad rings in that cylinder, the first thing to check though would be the upper end , meaning have the valves and rocker assembly checked

One cylinder is low in my 1998 Volvo s90 and the repair shops says the engine needs to be replaced. Is this true>


Not necessarily. I assume you mean that the compression on one cylinder is low? This is generally either the rings/cylinder, or valves. Sometimes a blown headgasket can drop compression, but will generally have other symptoms, ie., blown between one cylinder and another, blown between the cylinder and a cooling or oil passage, etc.

A GOOD shop will check more than compression, to determine where the exact problem is.

*A head gasket blown between 2 cylinders will have low compression on bothe affected cylinders.
*A head gasket blown into an oil or cooling passage will blow bubbles (gasses) into the affected area.
*To check the rings/cylinder, after running the first compression check, put a few ounces of oil into the cylinder through the spark plug hole. Re-run the compression check on that cylinder, and if the compression improves dramatically, you have bad rings on that cylinder.
*To check the valves, you need what is called a pressure differential guage. You place the affected cylinder at TDC (Top Dead Center) on the compression stroke. You then attach the guage, and apply a set amount of air pressure to the cylinder, usually about 100psi. One dial on the gauge reads input pressure (100psi), and the other reads how much the cylinder is actually holding. A drop of more than 10-15% generally indicates a bad valve in the head (as long as the prevoius checks came out OK). To determine which valve is bad, remove the intake ducting and listen for escaping air (Intake Valve) and listen at the tailpipe for the same (exhaust valve).

These are general procedures for tests so that you can see if your mechanic has actually performed them or not. If you want to run the tests yourself, I can give you more specific instructions.

Repairs:
Head Gasket - need to remove the head and check the head and block for cracks. Then replace the gasket and reinstall the head.
Bad Valve(s) - need to remove the head and have the bad valves reground or replaced by a machine shop and then reinstall the head.
Bad Rings/Cylinder - the engine will need to be removed and either machined and rebuilt or replaced.

Again, if you want any more specifics, please ask.

Hope this was helpful!

1999 volvo s80 t6


just put a compression gauge on each cylinder that will let you know if engine has a bent valve, gauges are relatively cheap. if the belt didn't have anything to do with your timing belt i doubt you have a bent valve, any check engine light? do you have spark? fuel pump turning on when key is turned to on position?
