Sometimes I find that you get to the point where if you fiddle with something, if you fiddle with it anymore to put it right, things get a whole lot worse. This sounds like one of those times.

 

Be ever so careful when putting body parts around and near the fuel lines and injectors when running. They operate at such a high pressure that any leaks or even the fuel vapour can enter your bloodstream causing serious damage to you - including requiring amputations.

Now I'm scared!

It might be my imagination but I was sure my car was driving much better this morning and no nasty fumes through the dash vents. I was able to accelerate up the long drag on the motorway in 5th more easily than before. (This could all be in my head though). After an hour driving I pulled over to nip the injector up which has the minor leak, when the engine was warm. I turned it about 1/6 of a turn and then it did that thing where you suddenly feel it's started to round. I stopped straight away and it's not popped out or anything. I poured a bit of water round it and there is still a leak but not sure if worse than before.

 

I'm a bit stuck now as I don't want to disturb it anymore as worried about completely stripping the thread. I'm trying not to have it helicoiled or replacement head fitted. In hindsight it had a different bolt in there so someone may have stripped it before.

 

The car's done 201k but is good in all other respects and still drives well with no noticeable fumes in the car. Am i naive to think it will stay the same or will it get worse? Or maybe better as the exhaust gases help to seal it? Should i just ignore it as it's a cheap car towards the end of its life? Any opinions welcome...

 

 

If there is room to helicoil it without taking the head off it shouldn't cost much, it's an easy enough job to do.

I might see how it goes for a bit and perhaps get the garage to do this next time I take it there. They're a proper old fashioned place so I'm sure they'll be able to do it or know someone who can. I'm just a bit worried it might shoot out at some point! Taking the family to euro Disney in it in July so need it reliable.

I had an injector clamp bolt hole helicoiled on the PT cruiser, cost £80 and did the job perfectly.

That doesn't sound too bad. I'm going to leave it for the moment as it's better then it was and I've just bought the sharan off here which might be put into daily use with the 406 on standby, we'll see.
