Thread: 4BD1 Injectors

Will check numbers when I get to Perth

Had them in my numbers book

Fleetguard AF4059K (Air, Main)
Fleetguard AF988 (Air, Inner)

Still haven't checked those filters

Had injectors done the other day. They tested them beforehand and 3 out of 4 were hosing badly. Haven't got any accurate fuel economy figures but I can definitely say I'm using less and thats while towing a boat on the return to Broome. Should be even better unloaded. Also noticed a definite reduction in EGTs prior it would max at 700 and now around 610. Engine used to quickly spike to high figures and its now a gradual climb

Chatting to the fella apparently these injectors only have an expected life of 150,000 so I can definitely recommend doing them, especially with a turbo

Plug for Paul at Perth Injector Exchange in Welshpool, fantastic service

Interesting, I'd always thought they were good for much more than that.
Great that it's made an improvement. Maybe I should get the ones in the county done. Only been in there 35 years - do you think it's worthwhile??

Nah, if they are going ok I wouldn't touch them. If you filter your fuel good they should last almost forever. I would only get they tested if I experience a power drop or rough running or smokey.

I got the injectors on my County done at about 150,000km, and was told that I had wasted my money as they were in perfect condition. (he still charged though!)

It is now approaching 600,000km, and I am thinking I ought to get them checked again. The point against it is that I have kept detailed fuel consumption records since I got it - and the fuel consumption has not changed significantly.

It is a bit of a curly one

To make it more interesting, for anyone other than myself who knows the car it wouldn't have been possible to notice a problem. It still idled fine, started fine and didn't blow ridiculous amounts of smoke. It also still had plenty of poke - when I mentioned power loss it wasn't a huge amount

I haven't had a chance to drive it without a trailer on the back, but I imagine there would be a power difference with the new injectors

How many k's is on your motor?

They are quite cheap to do up, especially as you are more that capable of pulling them out and putting them back in.

I rebuilt a 200 Tdi a while back, it didn't blow smoke, still went fine and started fine. I had the injectors done as a matter of course; I witnessed the bloke test them and saw how poorly they atomised the fuel and how much they dribbled when not firing. It's surprising how worn something can be and still run fine. That motor had 340,000 km on it

My advice would be to do them, cheap insurance I say

To add to that it's quite cheap to simply have them bench tested

That option will only cost you 4 new copper injector seals
