So yesterday i had my car on jack stands getting ready to do my 1x3 tranny drain and refill and 3rd/4th pressure switches.. when i went to unbolt the fill bolt i noticed my intake tube had a huge tear in it (where the tube connects to the throttle body). It explains so much because for the past month i had the engine code P0172 come on and off, my acceleration felt like it had a delay, and i was getting the crappiest mpg... I checked all vacuum lines and sensors but i never thought to check the intake tube..

I probably drove anywhere from 800 to possibly 1000 miles like this. Im wondering if there could be any serious damage done to the engine? Is there anything i should do like change the oil and filter? any kind of engine treatment fluids i should use? Just thinking about all that unfiltered air being sucked into the engine makes me a bit worried... i went to the dealership and picked up a new one to replace right away so everything feels back to normal and theres no more CEL on anymore

 

Changing the oil is probably the only thing you can do. If there's anything big that got sucked in, the oil filter would have caught it. Can't do much about anything now but I wouldn't lose sleep over it.

 

Pretty sure nothing that goes into the intake can end up in the oil pan, so it won't be caught by the oil filter. The only connection between the intake and oil area is the tube for vapor coming from the oil into the intake and I think there's a one-way valve on it. My intake has the same crack, there are generic ones on ebay for $20 to $30.
