Hi

A couple of queries

After changing the injector seals this afternoon, took the car for a run, only managed 5 miles before it lost power and stopped after a brief period of hard acceleration from a junction.

Found on the the injectors had worked loose,, new seal bedding in? this was re-tighnened, tried to start the car and it would not start.

Checked the injectors which were all recieving fuel, checked the inlet manifold seals, all ok.

attempted to start the car again and it emitted white smoke which smelt of rotten eggs/sulphur.

I let the car stand for 40 minutes whilst the recovery team arrived, I tied the car again and it burst into live at the flick of the key. on running I noticed a small amount of white smoke from the Turbo area which smelt of diesel, the excess fuel burning off?

Could the reason for the loss of power be the dislodged dirt from the injectors going through the system and blocking the EGR?

RAC could not find any fault codes when they checked the car

The second query surround the use of terraclean/Fortron Injector/EGR clean

Has anyone tried this and how successful is it in terms of cleaning the EGR

The car had 3 injector seals failed allowing the fumes to enter the cabin.

When we compared the old and new seals they looked different, the Mechanic who fitted them remarked these were off the 1.4 engine as the new genuine ones fitted perfectly. He cleaned the seats of the injectors to ensure a good fit.

We'll clean the EGR today, thanks for the reply

Quick update, had the Fortron injector service on Saturday, cleaned out all the dirt from the system and the car now pulls like a train returning an average of 68 - 70 MPG, up 10 from before the service.

Thanks for all the help

The Fortron Injector clean is similar to the Terra-Clean system of cleaning the injector/EGR and the tops of the pistons. Worked a treat on mine as since I've had it done I've average an extra 10mpg and smoother running.

Its less wildly known as there's no advertising in the media, probably a little cheaper in this case

Forte was bought out by Wynns a few years ago, you can still get the original product as some of the ex-directors for Forte set up another company call 4-tec.

I was talking to a rep for this product, his C5 1.6 HDI estate had over 400,000 miles on it having used the engine flush at every service as well as the fuel additive

Much was it to get done ?

Further problems with the seals as the fumes have returned. I think the injector retaining nuts have worked loose due to the temperature changes and they are the original ones from the factory.

Could they have stretched allowing the torque settings not to be retained.

I've read on another forum they are re-torqued every service, I've covered around 2k since the seals were done.

I will try new nuts and see how I get on

did you get the seats recut where the injector seals go

the injector securing design is poor. you can tighten to more then 5nm but if you cut through the seal there no good

The seats were re-cut, as this is the second set of seals I'm thinking the seats could be damaged. I've a spare set of washers just in case.

If I'm still having sealing problems I was thinking of replacing the allen keys nuts with normal ones, using 2 nuts on each stud, as in the lock nuts on the track rod end.

thanks for the reply

NO dont threadlock them as the stud will snap if you ever try to remove them again they do tend to come loose over time its not so much coming loose its the copper seal softening so just check they are tight at every service this is usually enough

I've a set of new nuts from the local dealer, hopefully this will solve the problem, thanks for all the advice
