CEL Solved?


Recommended Posts

Well I had asked elsewhere on my CEL P1128 code and my problem might be: oil separator bellows hose. This hose has been a problem in the 996 as well. The hose will deteriorate from the heat and oil and allow air to enter the intake system.

Do any of our experts here know where this hose is located? Can anyone supply a picture for this non-tech person? I got lots of duct tape! Okay, I'll replace it but would need our experts help. Anyone know where it is? P1128 is cyl 1-3 if that helps.

THANKS!

I don't know where the oil seperator bellows hose is but, I just cleared the same P1128 code on my 2000.

It was the oil fill tube. The section between the bulkhead of the engine compartment and trunk to the hard tube mounted on top of the engine. There is a TSB on this and it appears to be a common problem. I discovered this (I read about it on this site) after changing the plugs and cleaning the throttle body (I cleaned the throttle body thinking the problem might have been the IAC as it turns out the Egas cars donot have an IAC) didn't clear the CEL.

The give away that there might be a hole in the tube is a build up of oil on top of the engine below the tube.

A $28 part from the dealer. It took me about an hour to replace.

Good Luck

Thanks but do you have the TSB number? I couldn't find it listed here. I see the part you mentioned but want to be sure of the TSB. Regards!

I don't think the hose in that TSB is the same one that keoni is referring to. There is an accordian-style hose that is connected to the bottom of the oil separator. It is only a couple of inches long at most. It has been known to crack and cause problems.

When you buy an oil separator, it comes with a new hose. I don't think the dealer sells the hose separately. I bought the oil separator for about $125 (can't remember the exact number).

I don't have a picture handy, but the oil separator is located slightly to the passenger side of the center of the car, mounted vertically. It is accessible from the top and from the bottom. The hose in question is on the bottom, sticking out to the side.

The oil separator has been redesigned 3 times (so there are four different versions out there). I would make sure to get the latest one.

Point well taken, Thanks for the information!
