I will check the cam bearing caps. I torqued them to 8nm. I was also careful to put all the followers and bearings in their orginal locations. I don't know what the T vents are though...

[Marks DTM Calib]

T-vents are mounted in the head.....if not removed then not an issue.

I assume the oil pressure is ok?

[chrisdb]

Okay, did not remove the T vents. The oil pressure warning light does not come on so just assuming that the pressure is OK.

Well, stripped down this morning and it does seem to be a cambelt problem. The first thing you'll notice from the pictures is that the tensioner has 'un-tensioned'. Then you'll notice the fine bits of shredded belt. Then... why do the roller look like they'be been cooking? I'm just off to see if I can get a 3rd new cambelt kit

[Chris_H]

It looks to me as though one of your idlers is not turning and the back of the belt is burnt.  There's a spacer goes behind one of the single adjusters (forget which).  Did you put that in?

[jonathanh]

wow!   the bottom pic is interesting.  only the bottom of the roller is cooked - is this the one not turning?  that would also fit with the wear on the belt and frayed bits

to make certain here you do need to methodically identify the problem.  for example, lock the cams, take the tensioner off, remove the belt and then examine the rollers carefully to see whether they are loose (i.e. what one has slipped to make you lose tension) and if they are turning.

It sounds laborious but identifying the problem meas that if the belt kit is faulty at least you'll get it replaced.

remeber when refitting the belt, you should always be able to return to TDC and get the tensioner back on.  Even after 40k miles, the tensioner should be pretty much aligned with the tension mark at TDC.  

if you hit any problems post up here, I'll be online throughtout the day.  Inbetween stripping my cambelt cover off as I'm sure one of the tensioners is noisy on start up and I don't trust it

[chrisdb]

Thanks guys. Just back from getting a new kit. I suspect, from your comments that I screwed up. Will strip it down carefully and report back later.

[chrisdb]

Just removed the old rollers now. I thought maybe I had missed the washer off, but no... As suggested, thelower roller was totally siezed, but the washer was in place, and comparing it to the new new one, the washer is identical. There is also some scratching on the rear cover where it has come into contact with the roller.

I'm a bit scared now as don't know what I did wrong... :-/

[jonathanh]

ok  next step is to identify why the roller siezed up.  Is it a faulty roller?, try turning by hand and comparing to the new one.

is it jamming against the backplace?  in which case, identify why

is it that the washer is not big enough?

[chrisdb]

Okay, now I really do need some help! How can I work out what backplate I need?...

When I ordered the first kit I did not notice until I was ready to fit it, that the back plate was a different size. Also, for some strange reason I seem to remeber that the kit came with two seperate rollers and the back plate, but this kit only had one seperate roller.

So... I went down to the dealer with the back plate I had just taken off and eventually found a match. Atfer fitting this kit I had the strange noise and so after stripping down noticed that the bottom roller was oozing grease...

So... I assumed the kit was faulty. I compared the part numbers of the rollers and tensioners to the first set I had bought (which) was the wrong types, and saw that they were the same so I swapped rollers and tensioners over, using the new washers.

When I went to get the new kit today I did not have the old one with me, but for some reason I had it in mind that my type had EB stamped on it - I remembered this from last year when I followed the cambelt DVD. So I bought the EB one that they had.

After rumaging though the rubble to find the original I had taken off I found a washer much thicker than the new ones - this explains the siezure. The old backplate is marked 01, as is the one I have just taken off. The first 'wrong' one I bought is marked '6B' in small letters...

So why does the 01 kit have a washer that is too thin? And how can I work out what kit I need?

 :-/ :-?

[jonathanh]

there are two or three cambelt kits available.  the engine number is the key to the right kit.  i'll see if i can get the right kit number for you from the trade club website

[chrisdb]

hmmm... looked on TC site and it lists 93188674, which is the one that I bought today.... I think that all three of the kits have the same part number though.

[jonathanh]

I couldn't get on the TC site.  I did look at contitech and they do have three listed.  There is no way VX would have the same part number for three diff kits.  pulleys and belt lengths are different

[jonathanh]

does this post help?

and for mine I need part number 9201887 which i remeber is an 01 backplate

[RobG]

up to engine no. 08300418 = 93188674
from eng. no. 08300419-08578511 = 9201887
from eng. no. 08578512 = 93172354
