You mean the big one that comes out from the top of the separator place? With the plastic fitting that always cracks and ruins your day?
Yea, IIRC you don't have to remove that, it helps, but it isn't needed. You should only have to pull off the one that goes to the IACV.
It makes the job much easier just to remove the IACV, so if it needs to be cleaned, now is a great chance to do it.
LOL - exactly those! you know what i mean!
I have replaed several of those sensors and I have Never taken the PCV
hose off the block. I haven't removed the IACV either. It makes the
jpb a bit mor tedious, but not removing those extra parts made the job
go a little faster. I also lost less coolant.
thanks guys. where i live it's not convenient to start a job and need
something, and i don't know if it's where i live or what but pretty much
every 1990's or earlier large PCV hose in the block has cracked for me
when removing it.
