Squeal on acceleration

[uncle monty]

Hi, I have noticed that when you accelerate hard in first there is sometimes a high pitched squeal. This disappears as soon as it changes to 2nd. I have had cars with slipping belts in the past but this doesn't sound like that and only happens when I give it some welly in 1st. Pull off steadily and there is no squeal. Any thoughts or advice would be most welcome. Thanks.

Lift the passenger seat - look around the exhaust manifold, particularly the left hand end for any signs of soot. One or two of the studs are prone to going which can cause a noise like a pig in heat - not that I've heard either myself. Never had this happen to me, but it's worth a quick check.

If it is that, plenty of write-ups on hear of folk's experiences replacing studs.

Which engine? I sometimes get a sort of squeak from the transmission when pulling out of a junction. That's on a V6 so you tend to be able to hear any little noises that would be masked on a diesel engine.

It's the 2.5 td. Will have a nosey tonight to see if there is any soot. Thanks guys.

Ok, just had a look and unfortunately it looks like you are right, there is some soot around the left hand end of the manifold under the passenger seat. We are supposed to be going away in the bongo this weekend to Hunstanton. I am not good enough with spanners to take this job on myself so will need to take her to a garage, however I dont have time now before we go. In you opinion and experience am I ok to keep driving her like this for a week or two? I am guessing it is just a slow deterioration of the gasket which will get steadilly worse right, or do they tend to go very quickly once they start to blow? I don't want to be sitting on the hard shoulder getting nagged at by my Mrs and two bored kids....! In then short term Iis it bodgeable with gun gum maybe?

Shouldn't be a problem - I drove mine for weeks with it screeching at me

[uncle monty]

What, your Bongo or your Mrs...?!
Is it worth trying to stem it with gun gum do you think?

the manifold gasket is made of metal so quite sturdy---------------enjoy your holiday.
exhaust assembly paste may help keep the gasses away from the back of the alternator---------------but it may make the passy seat a little warm .

[uncle monty]

Ok cheers. Any idea how much a garage would charge for this job?

I've had the same issue and had to drive across France with a snapped no. 1 manifold stud. There were no ill effects in my case. Mine is in the garage right now being sorted, but I won't know the price until the end of the day. From what I gather, the price to fix can range from £50 to around £200 depending on the extent of the repair required (presume more expensive means that the manifold is warped and needs skimming).

I'll report back

Thanks for that, let me know. Fingers crossed for closer to £50.....

Mine cost £147 to fix with just one stud broken apparently. However, it you note my thread on matter, be very wary of coolant issues. It seems that in stripping the manifold down, some coolant can be lost, which if not bled properly, can cause problems. Issue to be resolved for me at the moment, so I thought it was worth a heads up......

Bloody hell is nothing straight forward?! Thanks for the heads up. Will make sure I mention it to the garage when I take it in. For now however, I intend to ignore it andtske her on holiday to Hunstanton

Unless the turbo is removed, there should be no need to disturb anything in the cooling system.
