Just bought a 1998 2.5 dse. Injector 1 is leaking. There is a little puddle of diesel that collects around it and when runnin you can see air bubbles escaping through it. Just wondered are the injectors easy enough to swap over and is there anything i need to remember to do when changing them? thanks.

Leak is from spill pipe. The bubbles are a minute gas leak from combustion. Not a big problem. You can slacken injectors and re torque them, may cure the slight leak may not. The copper seal age hardens over time. Make sure you get good spill pipe from a motor factors, there is a lot of **** about on Ebay. When you have cut spill pipe to length coat about half an inch at each end well with rubber solution to stop braid from fraying.

Retorque sorted my leak, give it a try.

Slight gas leak yes but not the fuel leak. I don't know how you would know the gas leak was cured unless you had diesel for it to bubble past. Fuel does not leak up past the injector combustion seal.

It was wet around the injector, well after changing the spill pipes, an mot fail here in Portugal. removed the injector, cleaned the treads on the head and injector, some engine oil to lubricate the injector tread, refitted and leak gone.

Diesel can only leak from spill pipe it CANNOT leak past injector gas seal. Combustion gas can, diesel can't. Copraslip grease is what you need on injector threads not engine oil.

I´m not telling you if it can or not, just sharing my experience, you can use it or not you decide..
Engine oil will let you screw in most of the injector by hand, avoiding cross treading. Sure i used what was on hand.

The oil will dry out and make removal difficult in future IMO.

I am sure you are, but believe me i do know what i am talking about. Liquid diesel cannot leak out from injector gas seal which is what you snugged down by removing and re torquing injector. Copraslip is an high temperature anti seize compound, that is what should be used on anything liable to seize through exposure to heat or gases. IE: Injectors.
