Not the first either.
Last week,while driving Money Pit around a roundabout I got a distinct wif of diesel smell.
Then another hint of the same wif today.
This led me to remove the plastic engine cover and sponge today to reveal a very small amount of wetness at the first injector base :shock: I know what this is the start of :rolleyes:
Now my question is, do I remove the injector securing bolts with the engine, hot or cold to replace the seals?
Many thanks.:)

easy diy.
Make sure you clean seats - injector cleaning brush kit on ebay with nylon brushes - tonnes of vids on youtube.
new seal washer and bolt essential. Make sure the bolt bore is clean. torque bolt to correct spec.

I have an old injector bolt with flats ground on side and bottom. I run that down to clean gently, and vacuum out with a narrow pipe taped to my mate Henry.
Henry's good at getting other loose crud out of the nooks and stuff to prevent it getting into open holes.

Plus Gas it is then.
I do have a broken injector bolt removal kit with taps. I imagine this should do the cleaning of the threads. I have used in the past, my hoover with the transmission oil filler funnel and small plastic tubing taped up. Mainly for removing dust and bugs from hard to get to air vents and heater matrix. It was quite successful but blocked far too easily :D
