200tdi misfire

[AbyssDJ]

seems like we've still got one after changing the head gasket... although to me it doesnt seem the same. generally seems to be running smoother, still breathing a bit from filler cap but nothing you wouldnt expect at 175k or so... at least it aint smoking from it like it was doing!

anyway.... how do you actually find a misfire? as in, what do you listen for? in all honesty, i aint got a clue... its the first engine i've ever took notice of, so im kinda used to how its always sounded.

one thing i can tell for definate though, is every now and then it misses bad enough to be felt and splutters a bit as if it wants to stall... usually lower down like 2nd occasionally at the bottom of 3rd. only does it for a split second then seems to be back to normal? anyone got any ideas? as it doesnt seem constant, im reckoning a [!Expletive Deleted!] up injector

other than that i think everything seems ok... bit smokey, but the oil needs changing and apparently synthetic/semi synthetic are no good in tdi's, so gonna change to mineral and see if that helps.

Could possibly be a sticking injector....

Just take them out and have a walk into Swadlicote  
Swadlicote Diesel are pretty good (have used them in the past) and to have the injectors checked shouldn't be more than about £5 each.

Or it could be a fault with the injector pump.... or another fueling issue  :(

or its getting air in cos matt never changed the copper washers when he had the injectors out  
if fuels coming out then air can get in

if that was the case it would chooch when its running

[AbyssDJ]

i reckon its the injectors... although mattys gonna get some copper rings anyway. it aint half wierd though.

made a wicked bang too when it blew the intercooler hose off last night.

[bombx3]

try chucking in some injector cleaner ( loads it wont hurt it)

[unknownmanxman]

when you say it happens in 2nd or 3rd, is that to say it happens when you rev it...

Does it happen only under load? Does it happen when it is idling?

[AbyssDJ]

doesnt have any trouble idling. every now and then it hesitates very slightly when revved. seems to do it most when slowing down and when pulling low in the rev range

as i say... i dont even know what to listen for... but you can feel it when it does the above

mattys got some injector cleaner for us i think.. cant get it til tues tho. how do you go about putting it straight in the fuel filter rather than the tank? need to do anything special?

[unknownmanxman]

Have you tried changing the fuel filter?

I had similar symptons to these, changed the filter, and it all went away! The filter was quite manky tho...

You can put the additive straight in the filter, drain a little diesel off using the water trap on the bottom of your filter, then take the bleed screw out, which is on top of the filter and pour it in..

[AbyssDJ]

filter most likely does need changing to be honest, iv just not had the £ in my hand to pick one up!

[simonred90]

yeah, dont be shy with it, warm up the engine, take a new filter and pour the injector cleaner neat into the filter put it on and kill it down the road for a bit. should clean it out a treat.

[AbyssDJ]

will do! gonna nick some off matty tomorrow if he goes to work... hes dying apparently! it gets killed down the road 100% of the time anyway ;)

Save the hassle and guessing, take it to a propper commercial Diesel Specilaist, they should be able to diagnose the problem, then give you an accurate estimate of what it will cost to fix it.

Do it right the first time, and save a fortune later.

The only problem for most people, are that 200Tdi Injectors are an exchange item, as they are dual spring types that not many can refurbish to spec'.  The last set I bought (Exchange) were about £100 each!!!!  About 5 years ago.  Worth every penny though..

They will also fully test the pump, and check out everything else, including the timing.  One thing they will appreciate though, is a clean engine and surroundings, and tell them everything you've done to it before you took it to them.  No disrespect, but DIY Diesel maintenance, is much more critical than any petrol engine.

Good Luck.
