past week ive noticed engine seems alot louder than usual, my friends were calling it a tug boat :lol i havent serviced it since i got it just ran alot of injector cleaner through it, i was going to service it and maybe use them zx1 oil additive see if it helps, is it common for then to be like that with 194k on?

regards ****

They are normaly quiet so an engine oil that has thinned out can cause a bit more noise.
15/40 semi synthetic is best for these engines.
Using supermarket fuel will make then rattle and clatter more,esp Tesco fuel.
Do a google search on supermarket fuel and you will be shocked.

Solved the battery/not starting problem then?
it seems to be fine now, so i can only assume cold weather was killing the battery off and its fine now :confused

as regards diesel it does run off morisons stuff, i was going to use the 10 40 my friends getting me from work it castrol but if its used on 200k trucks at his work it must be good enough for that and hopefully a little additive will quiet it down too

Have a search on this forum for tds egr valve.

Tips on how to block it off .

The car should not really have any turbo feel ie kicking in / pin in seat kind of feel,they just tear off from tick over,that kicking in feel is suggestive that the egr is sticking open a bit.

After a Corrado then the tds will feel a bit flat lol but they are quite quick esp considering the weight of the car.

Some trucks at my work have done up to and some well beyond 1,000,000k:jaw-dropping

They get run on castrol 15w 40

the more i think about this issue the more it bugs me, it just start doing it all of a sudden really after i ran lots on injector cleaner through now i think about it also so even if a vehicle run perfectly fine could they cause noise?

looks like an easy job to change them, so might get some from a omega or whatever i can and give it a go, also the mechanical fuel pump on cam if that a common thing to cause noise ill get one also from scraped, just gotta find someone with an omega in a scrapper whos doesnt know what its worth

ive explored the timing chain avenue and it seems unlikely it would just happen all of a sudden so does anyone else have any ideas?

The rattling could be from the serpantine belt tensioner. The bushes collapse or the shock absorber gives up & causes tapping rattling noises. also the jockey wheel & tensioner bearings can be noisey.

I too have a 325tds and it's been a noisy engine since i got it! I drive round with my head down in the towns as it sounds like such a Transit van! :(
I think mine too however is a lazy tappet and too much work to bother with for a bit of noise! think a replacement car may just be in order! :p

will investiage the EGR valve at next service this weekend though!
