Hi, i was wondering if anybody could help. When starting my car this morning it started ok but the noise the engine is making is terrible. It sounds like a tractor a real tractor. The car itself seems to go ok and does not appear to have a loss in power not that i have given it too much hammer. The only thing is that earlier in the week i had the cam cover gaskets changed which until now had made huge improvements in the cars running.
I know its a bit difficult to explain a problem like this on here but any help would be appreciated
thanks

Just an update on this problem. The noise seems to be coming from the front of the engine where the cover for the timing belt is?? its creaking and squeeking like mad so i dont know if its be cam belt that is at fault or if something as broke within that area
I guess i should not be driving this in its current state??
cheers

You guess right! I wouldn't even run the engine until you can pull the cover off and check the belt! When was the cam belt last changed and did it have new tensioner and idler pulleys?

Try taking the tension off the auxillary drive belt ('fan belt' to most of us ;)) or removing it for and see if that makes a differnce. The bearing in the tension tends to dry out and squeal like a stuck pig. The tensioner is top left as you stand & look under the bonnet. Don't run your car for long without the fan belt though as it drives your water pump.

i have an idea when it was last changed service book says at 30,00 miles and its now on 68,000. As for the tensioner and pulleys i could not say. I have a new canbelt sat in my garage waiting to go on but its not something i could do myself. Guess i would have to bite the bullet and take it down to vauxhall.
cheers

first, as above, pop the aux belt off to see if that is causing the noise.
Second, when you say that you have a new cambelt waiting to go on i presume you mean with rollers and tensioners. Belts rarely fail on their own and it could be that the noise you have is a tesioner letting go, when this happens the belt is off and goodbye engine.
Finally, don't bother with VX for fitting the belt, you CAN do it yourself. get the DVD and a locking kit: it's easy

How desperate do you need it....might be able to take a look one evening next week.

At least you live in the right part of the country .... ;)
Edit: ^^^^^ told you!

Sadly i am really desperate as it the only form of transport i own. I had all last week off work and could have managed without car but i guess i will have to bus it this week :P
Is there any good pics on this site so that i can tell what is what, i really do appreciate what everyone is saying on here but i'm still not sure what to look at so any pics would be great.
sorry guys
thank

would a problem with either my fan belt or cam belt let me still drive the car( not that i plan to ) its just that the car feels ok its not rough feeling just rough sounding. On the way back to my house when the problem first came apparent the car still pulled ok and was as responsive as ever, and to be honest if i wouldn't have turned my stereo down i would not have even noticed :-[. If i do manage to remove my fan belt, is it easy enough to put back or is there certain timings with this i need to know about.
apologies for my ignorance
thanks

Do not drive it umtill you know what the noise is, if it is cam belt related and belt comes off you will wreck the engine :(
The aux belt is on a sprung loaded tensioner, use a long 15mm spanner or socket and bar move tensioner away from belt, remove belt, refiting is reversal of that, just remember which way the belt goes round the pulleys.
Also bear in mind the water pump is driven by cam belt so check that is ok
-
if its suspect a tensioner i wouldnt risk it! car becomes a paperweight if it snaps! get mark to take a look what he doesnt know about omegas could be put on the back of a postage stamp!
-
would love to get Mark to take a look but i understand that he is a busy bloke and does not always have the time. But if he or anyone else is listening i am happy to pay my way out of this mess
cheers

The 'fan belt'/auxillary drive belt is easy enough to remove while you just test the tensioner bearing. You need a 15mm spanner/socket & T-bar on the nut in the middle of the top left pulley and lever it to your right. This will allow the belt to come off the pulleys. It's a bit more involved if you're going to remove it, you've the crappy secondary air pipe work to mover at the bottom right corner. Just try to make a note/phone photo of the way the belt is routed, there's 8 ft of it and it's easy to forget how it fits. ::)
-
if the aux belt has been taken off previously and put on the wrong way round it will make a howling noise according to the dvd ;) lol
i'd say it was a bearing on one of the idlers/on the tensioner on the timing belt
-
try JamesV6CDX if Mark is busy on atm!

Just want to check that this is the tensioner i need to loosen off. Also the strange oil leak type mark on the cover was not there yesterday/
-
Hi Mine was similar to your prob and it was tensioner pulley wheel ...my advice dont run it until you get the front covers off and check the timing belt tensioner and pulley wheel or it can be a costly job if the belt slips off.
I got mine done by a local mobile mechanic for about £200 and it was on my drive too which i could view being done.
I live near derby so try a local mobile man if you can find one.
cheers

Yes! That's your fan belt tensioner. You're moving the whole thing to the right via the 15mm nut in the middel of it.
Mmm? I can't thin of where that oil i coming from, apart from perhaps around the cams.
It might be an idea to slacken off as many of the cam cover bolts as you can and have a look inside. :-/

like andy says, if you undo the torx bolts on the actual belt cover then you can bend it slightly to have a nosey down to see if anythings in there
-
ok, so slackened off the tensioner, assuming i am right in thinking the fan belt was then not going round?? Car sounds worse than before so i have tightened this back up. Not in possesion of any torx sockets so unable to get cover off to look inside. sounds cream crackered to me.
thanks

ok let's just be absolutely sure of things here. When you say you slackened the tensioner off, what did you do? pull it over to the right hand side, slip the belt off it and the remaining pulleys, start up and still get a terrible noise. the point of slackening off is to take the aux belt off the pulleys so none of them are turning. You can then elimiate anything aux belt driven.
This means it is something else: very likely cam belt related so DO NOT start or drive it any more until you can eliminate it.
You've also got me confused about the oil mark on the cambelt cover. I can't think of anything that would cause that but you do have a leak of some kind there behind the aux tensioner and below it. It is possible that the leak is causing the noise (say water getting in the alternator). however, it is just a guess. best thing to do is to identify/eliminate the cambelt first.
don't worry about using a torx set. you should be able to get a normal socket to fit. the bolts should not be very tight. Give them a try.
-
Ok, checked this one tonight.....and the cambelt and cams are very noisey (possibly due to the cambelt being loose).
Checked the timing....and its not jumped any teeth so need to schedule in a cam belt change in the next few evenings.
-
Ok, belt and tensioners changed tonight, tensioner had siezed resulting in melted plastic and metal filings every where.
So....1.5 hours for the full belt and wate pump change and it fired up fine so all is good again!

Another success story for Mr DTM :y
