What is the large, empty rad hose type pipe? Intercooler?

woodbine · 2020-09-01 17:15:32

I have just changed the antifreeze on my Scudo 2.0 Jtd. To get to the clip that releases the bottom hose from bottom offside end of rad, I had to remove another rubber pipe above it. This pipe was bigger bore than the rad hoses, and had a large jubilee clip holding it onto the stub. This larger rubber pipe then turns through 90 degrees and then joins a plastic pipe which runs along behind the bottom of the rad, before it joins to another 90 degree rubber hose which attaches to a plastic structure under the engine near bottom of bell housing.

What is this for? Is it for the intercooler? Anyway, I disconnected this unknown ppipe from both ends using the jubilee at each end. As I undid the bell housing end of it and pulled the rubber hose off the plastic structure, a few drips of oil came out. Hardly anything. Is ithis normal? Should this pipe be empty apart from a few drips of oil?

Hope this all makes sense and one of the experts can enlighten me.

yeah this is the intercooler. its pretty normal to have a bit of oil in it. the engine crank case breather vents into this (before the turbo) and the turbo its self will leak a bit of oil into this pipe. nothing to worry about, when a turbo is spinning at crazy RPMs not many shaft seals can stop oil passing through.

if its anything, my intercooler had a little hole in it, only noticeable because it had a small oil stain on the front of it. enough for me to tell that it had a tiny leak.
sometimes a bit of leaking oil is a good thing.. lets you know if somethings needs replacing.

Thanks John. Never really contemplated intercoolers. Heard of them, used to see it written in big letters on the front of Volvo lorries 'TURBO INTERCOOLER'. Their 740/760 range of cars used to have 'INTERCOOLER' on the boot. Not anymore though as I suppose having a turbo and intercooler isn't big news these days.

Anyway I digress. This is my first oil burner and a few things are still a mystery. Thanks for enlightening me.

i remember when "INJECTION" was a big thing for cars to have on them. heh not that all cars after 1991 kinda had to be fuel injected to prevent CATs being poisoned when decelerating or anything. some cars had fancy hybrid carbs. the carb would have a fuel cut off solenoid that cut the fuel while the engine had a negative load (measured by vacuum level) fantastic system unless you had a vacuum leak.
the Seat Marbella with the 903cc Fiat OHV engine had such a system.
miss that car. know its still about. often wonder how its going on and if its being looked after to the level i did.

Yes, late 80s, early 90s that 'i' on the boot lid was the thing to have. Advertising the latest gizmos on the back of cars isn't new. In early 60s they put a small badge in the middle of MK 2 Jags to let people know it was fitted with new fangled disc brakes.

Suppose it was partly advertising and also to let people know that the Jag could stop a lot quicker than you would think.
