Cambelt (non mh)

[Figaro]

My daughter had a new cambelt fitted to her car. Since fitting it has run badly, felt "lumpy" and burned oil (blue smoke)
Could these be symptoms of incorrectly aligned cambelt ?
It was done by a local independant garage.
Is it something they could get so wrong ?
I'm planning to take it back to them but wondered if there was any way of checking this first
TIA

I once bought a Peugeot 106 diesel because it was low mileage, one lady owner, just had latest service with new belt and in brilliant condition but on the test drive it revved higher than I thought it should at tickover and the revs didn’t settle back.
I took to a local garage and they said the belt was fitted one notch out. It was was nice car after it was refitted.

Lumpy and running badly yes, but not sure about blue smoke.
Go back to garage and complain. If cam timing mis-aligned it can put the EML light on due to correlation error.

My old Discovery didn’t run right after the cam belt was changed. It was timed exactly right using lock pins for the crank and pump. Not an easy job with the belt being behind the water pump hence making sure it was right or so I thought.
A Diesel specialist I know had a look once I had it apart again and found pump had been changed at some time. It took a bit of trial and error moving the timing a couple of teeth either way but the way it ran afterwards was vastly different.
For a 200 TDI it rattled less and smoked a lot less on full throttle.

Its going back to the garage, I just hope they come clean if they did get it wrong and don't just charge for doing other work

It’s probably a tooth out job .not dental surgery

One tooth out. simple mistake to make if you haven't done one before. You cant rush changing a timing belt.

A professional garage shouldn`t make that mistake though surely, if indeed they did ?
I`ll have to wait and see what happens when it goes back in

I changed cambelt on my Fiat motorhome.
Could not lock cam and crank, it was one tooth out. Spoke to previous owner who bought it new. Never had a belt so wrong when it left factory!
Proved when locked in place and white marks on belt lined up.
Had similar on Fiesta, owner noticed straight away the improvement.

If it had never been changed it wouldn't have white marks... They are put there to assist timing after a belt removal.
Maybe had the belt removed for other reasons.... Water pump etc
Seeing as the engine is built out of the car at the factory the timing marks are clearly visible to the engine builder and wouldn't need white marks.

Note I edited it to point out the white cross bar marks were on the belt as supplied by Gates. Enclosed picture an example

Apologies..... I wrongly assumed you meant any tipex (usually) highlighting the timing marks.

 

[Larby]

Apology accepted.
I did not make clear initially I was referring to belt.
