Thread: Common rail diesel problems

Have to agree with Brian.

My D1 300tdi has had a Racor fitted under bonnet in line just before the LR filter when the Car was only 4 weeks old from new. Have had no problems with Water anywhere in Aus Including Darwin and the tropics. Racor recommend to change the filter every 2yrs, but when I pulled my old one it still looked like new. Changed it anyway for piece of mind.

Warning: They aren't the cheapest but are the best. I got mine from work about 12 years ago and cost about $150.

PS: The Landrover filter fuel filter under the bonnet is a Bosch filter and can be purchased at any truck/tractor/bus supplier for about $15-$20.
Bosch Part No: 1 457 434 159

THanks for the advice, gents, sounds like the racor is the way to go. Any advice on where to fit it on a d2? Cheers, Bob

One or two folks here have had big problems with water in fuel.

I noticed some exhorbitantly priced water filtration funnels at TJM the other day...probably good insurance for filling up from remote supplies.

When it comes to TJM Ned Kelly was a gentleman.

Check out your sediment filter after a trip out west.You will be surprised at how much crap can get in there.
Upon returning from trip I had my disco in for a service,I asked that the sediment filter be checked.We all know that can be a pain in the ass and my mechanic asked whether I really needed it done I said yes.Upon picking up the vehicle,I was told that there was nearly and inch of crud in there.So the moral of this story is " fuels ain't fuels..Sol"

I've never seen a commonrail injector up close, but I'm told they have a tiny pilot hole which uses the high fuel pressure to help open the valves and this is what clogs up.

Can anyone confirm or deny?

I have been putting Fuel Doctor in my common rail from new. Tested it at home and definitely separates water from diesel, which naturally happens anyway. But I'm hoping it catches and suspended bits of water and rubbish whist filling up or driving.

I have not learned how do dump the water filter yet, but they did so on my last service and had no comments to add. Can only hope it works and used as directed a bottle goes a long way for $35.

So you're seperating it out the water but keeping it in the system?

Yes no doubt.

I'm planning a trip to Lake Eyre in April and I will spend $60 on one of these:

Pro Quip Mr Funnel Fuel Filter Funnels

Much much cheaper than the price of repairing the fuel injection system.

I don't know how efficient they are at removing water...there is no data available for this product but there are good reports on the various toyonissabishi forums.
