Description
For a change from mating insects etc...
My elderly Volvo suddenly developed a sort of knocking noise at the front of the engine which from inside the car sounded rather like a Chinook helicopter. My lorry driver lodger couldn't diagnose it, as nothing was obvious, but said I shouldn't drive it till it was looked at.
My brother is on holiday in Canada (sod's law) and so yesterday I gingerly drove it to the friendly garage which does our MOT's and they took it into the workshop to look.
I was summoned from the office: "What noise?" they said!
So I drove home and on arrival the Chinook returned!
Back I went and thankfully they could hear it and instantly saw that it was this bottom pulley which need what they called 're-torquing'! So later in the day I went back and only had to pay for half and hour time.He said it has a bit of a natural wobble but the noise has stopped and it's safe to drive.
We decided against a 2 1/2 hour engine strip to find out the cause of the wobble, I don't need to find out out just yet !

You have made it look a bit rusty Andrea, just be careful !! Found some mullien moth caterpillars in the garden today - the neighbour has them now.
Good image captured !!!
It looks really grim with the post work! Glad it's not that serious for you. They do try and make things sound so complicated don't they, re-torquing? Tightening up a loose nut, they should say! A 5 second pull on a torque wrench will do it ( A wrench that indicates exactly how tight a nut is ) to check it is as at the recommended tightness. They never get tighter as a result of engine vibration they work loose. If they are too tight it is because the mechanic didn't use the correct setting last time he did it!
Well, if he tightened the nut, I hope you're good to go for a good while now, and you saved a lot of money. Good luck.
Good image captured !!!
what if the nut objects to being tighten? did they talk to the nurse before hand to see if the nut really needed tightening? Great image with the postwork and glad your car is okay for now
Amazing capture and post work Andrea. Glad your vehicle is fine. I will have to repair mine as well. It struggle to start. Had to push start it a few days ago. God bless.
wonderfully captured
So glad all is well with the car. X
Glad it was an easy fix this time, and I hope it stays driveable!
Awesome captures and glad it is back running...::::))))))
cool
Maybe a pulley replacement would be an answer - but keep in mind that I am a computer geek and my best friend is the only one allowed under the bonnet of my car!
I know I've got a screw loose and I'm a bit of a nut but honest I've not touched your car,
Lucky you to find an honest mechanic and an easy fix. My first thought was rod bearings which means an engine rebuild. I once read that British cars were made by sadists for masochists. I've owned three British cars in my time so I am an expert on noises and their causes.
Wonderful pics. Andrea ! Happy to hear it was a easy fix !
