Hi all,
I am going to try and take off the LIM on my FC tomorrow, there are 2 oil injectors plus the brittle lines attached to them.
How do I remove the injectors without damaging the lines etc? Are the injectors like a banjo bolt with the oil lines being a banjo fitting - thus meaning that if you keep the banjo still and turn the oil injector they should unscrew?
I am hoping not to have to take the turbo off to remove the LIM, but I might have to :(
Which lines do I have to disconnect? I don\'t need to remove the turbo completly, but probably just unbolt it from the car and move it slightly to get access to the LIM bolts?
Oil Injectors - yes they are 1 way banjo bolts - they are torqued up to mid 20\'s NM - so may take a bit of budging - and they will probably try and twist the oil feed banjo\'s as they have copper washers top and bottom that seal them - these deform slightly which tends to mean they make everything \'stick\' together. There\'s about 20 degree\'s play in those oil lines before you get into any major trouble - so just be very careful when \'cracking\' them. It\'s probably worth buying some new copper washers - if you a used one down to the local motor factors you should get replacements. I can\'t remember if the are M12, M14 or M16 off the top of my head.
If you have to move the turbo - probably easiest to hit the 4 bolts between manifold and hot side casing - you\'ll have to be under the car to get at most of them, but it\'s doable. You\'ll need to remove the following though:
Water feed from LIM (you\'ll have to take that off anyway)
Water return to water pump - this is a v shaped hose and it can be a pita to get off
Oil feed - undo at the coupling on top of the engine behind water pump
Oil return - this is a pita too - access is from underneath - through engine mount for one of them or use extension wobble bars - again a pita
This also means you need new gaskets for:
Water feed
Oil return
suffer leaks if you don\'t replace them !
Some folk can manouvere the turbo out of the way by undoing the oil drain at the front housing - it\'s easier to get to, and you probably can get away without replacing the washer as this is under a lot less heat and can be sealed with RTV.
Thank you :) I will try and get the LIM off without having to remove the turbo, sounds like its almost easier to remove the whole engine and drop in my BP engine at this rate :rollin
