Oil in intercooler - stuffed turbo?

So I chucked it all back together and swapped out the afm, went for a quick drive and I noticed as i pulled in back home that I DO have a flashing CEL, if only I could read it..

the oil is coming from the breather pipes in your turbo intake. It is quite normal to see some oil in your intercooler and it will become excessive if the oil level in the sump is too high or your bores or turbo are worn. Per other comments this is not related to the cel.

On your ECU a flashing cel is specific to a misfire code. Usually a faulty coil pack or plug will trigger this . I have seen faulty injectors also trigger a flashing cel. The ecu will assume a misfire if the injector drops out of sync with the crank sensor. On one car this was caused by a connector plug on an injector not being pushed fully home after a rebuild. The stored code on the ecu will isolate this for you once you gain access. Drop me a pm if you need any help. Cheers .Alistair

OBD2 scanner came in the mail today, so just finished checking out the codes. Said there was 4 old ones and one new one, "p0500, p1518, p1590, p0136 and finally p0350." Assuming p0350 is the newest one, this makes a lot of sense. P0350 - Ignition Coil Primary/Secondary Circuit Malfunction. What should I be checking to remedy this CEL, perhaps one or more were duds? they came off a 2001 V7 with 115ks on the clock. I may not be the greatest DIYer but they all felt in place correctly etc.

How much oil is inside the big plug on the driver\'s side strut tower?

Just a wild option but it could be the whole failed-avcs-sensor-oil-in-the-ECU thing.

AVCS Heads are 03+ aren\'t they? BL/V8?

P0350 - Either Plug/Coil Fault.

Check the condition of your Plugs, Gaps etc.

Then test Spark at all 4 Cylinders, weak or dis-coloured Spark could mean a fried Coil Pack

No, V7 STI has (intake?) AVCS.

I basically only swapped the coil packs, no cleaning or anything, should I try cleaning the connections on the coil packs first? What should i clean them with if so. I also have my 3 old coil packs that worked fine and the 1 stuffed one I could try fix the situation with.

Jdm had avcs at v7 sti

Contact Cleaner, but it probably wont help. Check your Spark as above, then start swapping in known working Coil Packs.

In the first instance, given there are historical codes stored for multiple sensors and P0350 has now appeared (which in my experience is usually the code the ECU throws when it cannot attribute a misfire condition to a specific coil pack), I would recommend you check your engine harness earths (specifically the harness earthing bolt to the top of the passenger side inlet manifold) before you start swapping coil packs around.

I\'d be checking that main loom plug... you are around there anyways, the avcs sensors are known to leak, forcing oil up inside the loom, some guys have had it forced right back to the ecu. 5 second job to check

[Skatieguy]

Swapped over the 2 passenger side coils, found a bit of oil on the front left.. connector? missfire/cel issues gone, so will swap them back over again tomorrow. Will know in a few days whether the cars actually using oil or not. Also this huge cable tie, does that need to be replaced after checking the plug?

[Rosssub]

If your going to put the suspect Coils back in, do it one at a time to work out which ones bad. Your Cam/Rocker Covers aren\'t leaking are they?

Have a read through this link regarding the AVCS/Oil in Loom Plugs etc:

Opened the main loom plug today and did not see any oil in there, so hopefully all good. Seems that one of the new coils are also faulty, swapped some around (again) to get rid of more misfire issues (same as what it\'s had for 2 years), not the new bad, CEL one. So just a matter of time before I know if it\'s good or not now.

[Rosssub]

Time for a new set of Coil Packs. Swapping in second handers will never end...

[Skatieguy]

See how we go, right now I\'m just happy to have it finally running how it should\'ve been since the rebuild. (pretty much right when I bought it.) I feel like I owe you guys a beer after all these dumb questions
