Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Hello. My name is XXXXX XXXXX I will be helping you today.
Considering you were idling there is a VERY slight chance that valves were not bent but I wouldnt count on it.
Most likely you will be looking at bent valves and a fairly expensive repair.
Hi.. I was wondering how familiar are you with the Volvo S60 2.4T timing belt damaged after it broke??
I am pretty familiar with them.
They are an interference engine and when the timing belt breaks with the engine running generally the valves will be bent.
I have seen several of them where the timing belt broke and never seen one that the valves were not bent.
How can I tell if valves bent?
Yes. Generally close to 2000 or so./
Well theres two ways.
Any particular sound on engine after the timing belt is installed?
The way I do it is to just slap a belt on it and run a compression test.
Or you can roll over the engine to where the valves are closed and run a leakdown test on each cylinder.
If it runs at all it would sound like crap.
what is the average PSI per cylinder ?
I guess I will find out after the belt gets installed..
Generally over 130 or so.
Youre more watching for a difference between the highest and lowest cylinder of no more than 10 percent.
If you got bent valves one will have zero compression.
the died when I was on a red traffic light.. Would that make a difference on the dammage?
Yes.. that gives you a SLIGHT chance of no bent valves.
car died on a red light
But I wouldnt count on it. Its a very slight chance.
You dont have to put it all back together to test compression. Just get the belt on enough that you can turn the engine.
No point in putting everything back together if the valves are bent.
to do a whole valve repair job, the whole head has to be removed?
valve repair job means new head gasket as well?
Yes. New head gasket, valves, timing belt and components, water pump.
While they have the head off they will also resurface it,
:( OK.. I'm hoping for not much damage after the belt gets installed.
Thank you for your help
Thats about all you can do unfortunately.
new water pump was installed about a month ago with a new timing belt
Hope and pray for the best. You may luck out. Your circumstances with being at an idle leave you at the best odds.
Oh, okay. Well then this sounds like warranty work.
So thats good news kind of.
warranty by who?
By the shop that did the timing belt if one did.
Unless you are the shop.
some oil was spilled on to the belt few weeks before it broke...
If you are the shop file a labor claim with your parts supplier so you arent eating the cost.
I think that caused it
It should have been cleaned off.
WHat are the must change things on the valve job??
The head gasket and bolts and resurface the head.
Plus the timing belt.. obviously.
I see... main cost is the labor.. I guess
how many hours labor this repair is rated at?
Yeah mostly. Between machine shop and parts you may have 400 in actual cost.
The rest is labor.
about how many hours labor?
18 hours or so.
Someone experienced with them can get it done in under 15.
ok... Thank you..you were a good help
