We're in the process of fitting a rev 3 engine in a rev 2 car. We're nearly there but there are a few differences. There's a hose which is attached to the underside of the inlet manifold which we don't know what it's for/where it goes. Can anybody help with it's identification. I've attached a picture but I don't know how helpful it'll be as it's difficult to get a clear picture. Looking at the engine from the inlet side the hose is on the underneath to the left hand side of the manifold. Any help would be gratefully received.
The hose I'm talking about is approx 1/2" diameter and is in the middle of the picture with the rubber protection. Thanks

Re: Mystery hose
It's not a great picture. The hose comes from the left of the inlet manifold on the block. It's fairly long, about 1' and has kinks in it that look as if it should possibly attach to something on the firewall. Problem is, the equivalent hose isn't on our rev 2 engine we took out, or at least in the same place, so haven't been able to compare between the two engines.
Re: Mystery hose
Here's some more pictures of the mystery hose, maybe somebody knows what it is. It's in a really awkward place to get a photo so they aren't the best.

There is a finger pointing at the hose in each of the photos for identification. To be honest it's hard to spot the finger in a couple of them. Thanks for any help.

Re: Mystery hose
Massive stab in the dark .. Vsv (stock boost control) maybe
Re: Mystery hose
Looks to me like the standard catchcan drain hose.
Re: Mystery hose
It's on the left side of the inlet manifold, that nut you can see is the left most nut for the manifold and my finger is on the hose in question. It's just to the right of the dizzy cap.
It's chunky, about 1/4" internal diameter with thick hose walls.
Our VSV was already deleted on this engine, the other end blocked off at the wastegate. This hose however, wasn't blocked off so it made me assume it must go to something. There is no equivelant on our Rev 2 engine to compare to however.
Catch can is fitted so don't think it's that, it is however right underneath the catch can. If it's the drain, where does it go? Only 2 hoses have me stumped on this engine then it's ready to go back in the car!

Re: Mystery hose
do you have the stock catchcan??
there are 3 hose outlets on it.
1 of those is a drain which goes back to the head, ie where you are pointing to.

Re: Mystery hose
That looks to be the one! Thanks Jim. I'll have to double check the catch can for the third outlet. Come to think of it, I didn't really check it over, just hooked up the cam cover and inlet hose... possibly been a slight spanner!
Thanks for the help guys

That is the can I've got, I'm sure I'm going to feel rather sheepish when I go to the garage tonight and the third outlet isn't attached. Thanks for the help Jim
Re: Mystery hose
no worries
