If its just a regular drive belt its impossible for this belt to "kick back" and bend a vale. However if this was a timing belt its quite possible to bend valves if it breaks. You problem could be a crank sensor that may have gotten damaged when this belt broke. If the crank sensor is damaged it won't send a reference signal to to computer therefore the vehicle would not have a spark to start. Godd Luck

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?

IS A 2001 VOLVO S80 2.4 MOTOR A NON INTERFERANCE MOTOR


autodata publication 2012 states that it is an interference engine in which there is a possibility of valve to piston damage in the event of timing belt failure. It is mostly to occur.
if you are removing the belt as a precaution then make sure all the timing marks line up prior to belt removal and once the belt has been removed do not move anything
If the belt has broken you may check for bent valves by placing the head upside down and putting fluid into the combustion chambers around the valves . If it runs out then the valve is damaged
If you find one then check the lot
Basically it is professional mechanics to assume that the valves are bent anyway and have them checked before reassembly of the head.

2000 volvo s80 2.8 long cranking


Probably Caused by old engine and burnt deposits on the valves and spark plugs. Change the plugs, add cleaner to the gas (get it from Pep Boys)

What happens if a 02 Volvo s80 v6 turbo breaks timing belt??


You have no valve clearance, it definetly hit a exhaust valve , you will need a valve job and find the reason your belt broke to begin with. It is impossible that a valve did not get hit

My car has 77000 miles. timing belt broked and did damage inside enginee. should i change all enginee or put new timing belt and change the volves.


If you are paying someone to do the work. It is cheaper most times to replace the engine. If it were mine I do the work and would fix the engine. Depends on the damage also. You wont know until you get it apart. It can scar up the piston top and be ok. If it scars up the valve seat in the head, the head is trashed. If something broke and scars up the cylinder walls to badly it is trashed

Broken crank shaft the mechanic said he wont be able to know if valves are bent until he puts it back together of course he said the valves are bent. How difficult is it to replace valves?


Find another mechanic. you got ripped off. A broken crank does not mean you cant check the valves. Called a leak down test. This engine should have been replaced. And probably still should. Your talking about a $1500.00 job.

Volvo S80 T6 : What happen with motor, if timing belt broken?


It is common for issues to come from any of the driven shaft bearings.
I mean to say -If the water pump fails.If the idler bearing fails.If the tensioner bearing fails - which is common - for peopleto not change ... gambling that it seems "alright" - right now - at the point ofreplacing the timing belt.
If the timing belt does snap -
Then every intake valve in the head will become bent.Search for a "good used head" and see how manyof the damaged heads are available with bent valves.
If you are making highway speed - the engine will become destroyed -with piston damage.
If you are more fortunate - the valve work can be done.But the labor and the physical amount of work to getthe job done is long and intense - even for those people who do it regularly. ... and costly. I found a reman head for $750exchange.
There also is galvonic bonding for the head bolts - they becomeelectrically and chemically welded to the alloy block - nearlybreaking off - with the attempt to remove each head bolt.
When they do break - someone with grit has to create theright tool situation to drill, use electric current to break the bondand remove what bolts do break.
What could happen when you ignore the time interval thatVolvo suggests - You could loose your car -You could need to replace your engine.You could wind up buying a Toyota.
The options are unending.

Change the water pump, timing belt, tensioner and idler bearingall at the same time.
The special tools for the Variable camshaft timing are notsuggested just to be suggested. They are needed to accuratelyset the timing for greatest engine efficiency and to keep thehead valves from becoming damaged - after a novice attemptsto install just a replacement timing belt.
Flush the power steering fluid while you have all that mess off
to service the front of the engine.
Ignore it all, and it will go away a tow truck to the salvage yard of your choice ... or wind up paying up over and beyond $3500for repairs that might be possible - if someone is willing to takethe job on for you - other than the dealer.

Timing belt felll off on highway,will there be a lot of damage 2000 volvos-80


Volvo recommends for Volvo S80, changing the timing belt every 105,000 miles. Needless to say, they are pretty religious about this now.
The B20, B21, B23, and B230 engines are non-interference engines, meaning that the camshaft can be rotated independently of the crankshaft and no damage will result to the engine. That is, if the timing belt breaks, the valves will not hit the pistons; the engine will simply stop.
On the other hand, the B234 16-valve engines and any of the other Volvo multi valve engines are interference engines. Loss of the timing belt in these engines will result in severe or fatal engine damage.
Your car might be fitted with:
2.8L (VIN 90, 6th & 7th digit, B6284T eng, turbo)
2.9L (VIN 94, 6th & 7th digit, B6294S eng)
