I had the engine light come on today. When looking in the engine bay I noticed the feed tube from the oil filler pipe to the rubber accordian tube in front of the throttle body ( I think it is called a bellows tube?) was broken. it is broken at the throttle body end. The plastic elbow comming out of the rubber has snapped. Can anyone tell me if this plastic piece comming out of the accordian tube is a seperate part to the accordian tube or the whole thing is one unit as it looks like one piece to me.? If someone has a parts diagram could they check this for me please and let me know what this part is called and part number if any thanks.

Also pulled out the filter in the Revi intake and noticed it was very oily. So checked the dipstick as I had the car serviced a month back as I was too busy to do the oil change myself and noticed that the car is still showing full and I have done a 300k's since so expected it to be lower. I think the Mazda dealership had overfulled. Could this cause oil in the filter? Not sure if I am dealing with two seperate issues or one?

 

Two seperate issues, the oil in the intake is actually 'normal' in that they all do that if you drive hard.

The bellows leak is much more serious, if air gets in there it will weaken the mixture (the sensor is up front) and can (and will) cause damage. Get it fixed pronto, at least seal it so no air gets in.

 

I just noticed that two if the three black plastic fittings on the bellows have holes in them on my car, so I too will be looking to replace them. For now I have taped them up with electrical tape as a temporary fix.

 

Thanks Stealth, Thought it was two issues. Not driving the car at all untill I can get it fixed. It has snapped right of at the plastic elbow. I can't work out if I can just replace the elbow or I need a whole new bellows tube?

 

Pretty sure they sell the little plastic elbows cheap at the dealer, I broke one myself.

 

Thats good news, it seemed a bit crazy to have to replace the whole bellows unit but nothing would surprise me with car part. It just didn't wan't to come out easy and I didn't want to force it. I am guessing you have to turn it in one direction then it comes out. thanks heaps
