Well my 2.4 90 tddi didn't even last it's first week even after all the tlc it's had got a call today that the van has lost power sounds like it's missing and smoking! i wasn't nowhere near it so the guys had to carry on! had a look this eve and this is what it's doing! very tappy top endy but not diesel knocky, hesitant and sluggish sounds as if missing, blueish smoke,also on tickover it sounds like it's pumping out of the inlet but get it to about 60mph and it seems to smooth off and run ok! i've whipped the rocker cover off to see if the timing has jumped but i cant see any damage and all looks ok! could it still have jumped? secondly i'm thinking pump?or thirdly how about a pistonring? bloody thing cheers

[mobilevanman]

i may be wrong but it sounds possable u have an injecter going or worse a piston goning further testing to be done would include leakoff test on injecters and compression test on engine

good luck

Cheers i'm planning on doing a compression test! i thought the tddi injectors were ment to be bulletproof?

My 54 plate tddi 115ps one managed to snap a valve spring and it sounded just like you have explained, could be wroth checking the valve springs

[belly]

cheers AK will check that aswell! keep it coming lads

[coconut]

Timing could have just jumped 1 tooth

But as the others say check simple stuff 1st like valve springs, rockers etc then I'd go for the compression test and see what that brings up

Also check the cam to see if any of the lobes have cracked and are spinning on the cam

[belly]

Cheers Coconut you nearly got to look at it today! as it limped from your hometown! wish it had stopped there actually or fallen of the bridge

[belly]

If it has jumped one tooth will it have damaged anything? i'm guessing the timing can only be checked with the front cover off?

[coconut]

I was on a nice long roadtest today, so wasn't in the workshop for much

If it has jumped 1 or 2 teeth very unlikely it would damaged anything but thinking again the earlier engines didn't jump but it would have to have the front cover off to check but you could check the crank to pump timing and if that's slightly out then that's a good indication the timing has jumped but do check the basics before ripping it apart to much

cheers well if you need another long roadtest feel free to head this way did i mention my brother in law is a manager for carlsberg and my father in law is a butcher

I'll help ya fix it mate

[belly]

I must admit are BBQ are good tons and tons of meat and the odd one or three broken cases
I've never had a front cover off yet! Can it be done without pulling the whole front off? I know this will give more room but I don't want to leave it where it is with all the front off if that makes sense Looks as though there's room if I drop the rad out !

[jacko1611]

u can get the front cover off without takin the front end off. dont need the rad off either just the fan and fan cowling

[belly]

cheers jacko had a quick look again whilst it was still light! and decided theres loadsa room also chaps im going to buy these bits and bobs are they the tools for the job?
