phah simple stuff...
wait till you have to change the statermotor in an IMV...
you have to pull the whole engine and transmission out....
and when youve done all of that and your putting it back together when you drop the 13mm spanner that your using to do the exhaust flange clamp back up you have to take the whole engine and transmission back out...
Then when youve got it all back together and your unhooking the lifting sling when you co worker drops the shackle pin and it falls down you have to take the whole engine and transmission out....
oh, want to do a valve adjustment....
guess what.. yep engine and transmission out....
how about change say the oil pressure sender.....same.
yet this is allegedly a very well designed bit of kit.
you older generation of mechanics had it easy,,, at least you never had to pull the engine out of something just because you dropped a spanner
:)
