carb cleaner & injector tar
Today I set about removing the long overdue tar build up around my injectors (3 & 4) which have been leaking for quite a while.
I removed a lot of this hard resinous substance mechanically with a screwdriver. After that I have been working carb cleaner around with a toothbrush and have made reasonable progress, mopping up the black slurry with kitchen towel. It has been slow going.....
My question is - would it be a terrible idea to leave a good dose of carb cleaner in the wells around the injectors overnight? I've just soaked the last of it up but there is still a fair bit of "diesel varnish" or crusty tar around the bases of the injectors and the holders/clamps.
I was hoping that leaving them soaking in a puddle of carb cleaner overnight would dissolve all the hard to reach gunk in the crevices etc but am wary that it mightn't be a good idea....
Need to get the whole area sparkling before attempting injector removal & seal replacement.
