Oil leaking from intercooler

[Kam]

This morning, I noticed that there was oil that had dripped from the front offside of the car onto the drive. I am sure that this is coming out of the intercooler as when I recently had to remove the front bumper to refit some HIDs, the base of the interfooler was caked in oil and crap. There was also a lot of oil in the areas of the front bumber valance that goes beneath the IC.

A bummer but just wondering it is it normal for this much oil to go through the IC? As far as I know, charged air goes through IC with some oil but this much??

I hope I am not looking at a bigger problem other than a blown IC

Its normal but I would suggest you check the seal out of the intercooler and the one on the the pipe which joins the long one in the off side wheel arch mine was doing the same it just needed a new seal which did not cost much at all.

I had a passat before my leon and I used to wash the intercooler through every couple of months loads of sh**t used to come out.

This is fairly typical:

So yes, it's normal for a small quantity of oil to accumulate in the pipes/intercooler, and to seep out around the pipe joints under pressure.

Thanks!

There was a clip that was undone when we had a look with the bumper off. That was re-secured. Never noticed a seal though, just IC end of the pipe going into the pipe, no seal, just a metal clip holding them together. Something missing?

Is it possible to have a look without taking the bumper off, just unfastening and pulling back the wheen liner??

There should be a rubber ring that sits on the outside of the pipe insert (ie the male half ) and seals it into the housing.

Hi there! So you are suggesting that there may not be a leak, just a case of oil being squeezed out under pressure??

Only noticed some had dripped out this morning, car has been stationary on my since Thursday afternoon...

You will always get some oil in the charge pressure and inevitably some will come out of the joints or in some cases just one joint.
It does come out of the intercooler joint on mine and I cant stop it but its not that much so I have left it!.

 

[sssstew]

yes, but at the same time it shouldnt be an amount which will cause a drip....

 

[muddyboots]

Agreed Stew, makes me wonder whether the O-ring is missing or damaged.

Back to this topic again

I cleaned all the exterior of the IC with Gunk about a month ago and underneath around the join. That was roughly a month ago and now there is so much oil, starting to drip once again. In a month the car covers about 1,400 miles.

If it is the O Ring that is damaged / missing, is it simply pulling the IC away from pipework and replacing the O Ring?

Thanks.

 

[sssstew]

yes Kam.

Sorry for bringing back up an old thread....but does anyone know the part number for just the o-ring??

Spoke to Seat this morning and they said it doesn't come seperately...you have to buy the whole pipe & joint?!? Which doesn't sounf right to me....

I shall have a gander on ETKA tonight if no one else finds it before me.

It would be best if you told us what model car and which engine you have, but I've guessed at an Ibiza 2004 with an ASZ engine. Part number for the seal is "3C0 145 117 D" (original part number 6Q0 145 117 has been dropped) for the inlet side and "6Q0 145 117 A" for the outlet side.

Of course if your car is different then the part number may be aswell.

Seals can be purchased seperately, I got some for mine from VW, though I had to wait a couple of days.

Sorry just not been my day today...it's a leon cupra tdi 53 plate so it's the 150 pd engine, has that got the same IC setup as the Ibiza??

Cheers guys....

Righto, ETKA lists the seals for the intercooler as "Part number unknown" but links them to the inlet and outlet pipes, so it could well be that Seat don't supply them as a single part.

However, ETKA for VW lists the same engine (ARL) for the Golf GT TDI and they list the seals seperately as "1J0 145 117 A" for both inlet and outlet on the intercooler connections. Different part numbers for seals further on down the line.

Maybe nip along to a VW dealer and ask them.

 

[glynnd]

Did I not say get them from the vw dealer!

This is in case some of you out there do not know this.
All parts for seat/vw now come direct form TPS (trade parts supply) who effectively are vw. If you can get them from a vw dealer you can get them from TPS. I believe you can buy direct form TPS without a trade account, effectively cutting out the useless Seat dealer (sorry mine really is crap). Just find the TPS outlet nearest to you.
