Hello

To my dismay when attempting another go at the throttle body clean, i found a large crack in the air intake pipe just before the throttle valve (see pic).

Is there a proper way to fix this without having to replace the whole damn thing? Please help i am very sad

 

Find a flexible coupler that fits over the raised ridge on the "Y" part and will also clamp over the throttle body. That's your only option to replacement.

 

Looks like you found the cause of your rough idle.

If you can't find a silicone/rubber coupler as mentioned above, take the cracked part off, clean it out, and wrap some silicone tape around it. Probably won't be air tight but should last while you order a coupler. You'll have to take it off anyway to measure the diameters.

 

*Update*

got some epoxy putty and silicon tape. The crack is much worse than I thought half of pipe connecting to the throttle body fell off once I loosened the belt holding it. Used epoxy putty to 'patch' it in place, then wrapped it as best I could with the silicon tape which set in a minute, then retightened the belt.

No vibration when idling!!! I hope that three weeks of intermittent driving with the broken pipe did not do irreversible damage to the engine through sucking dust into the cylinders

 

Was your check engine light on? With a crack that big you should have been getting a lean or MAF code.

 

nop, nothing came on except that minor rough idle

 

Them maf sensors are a swine to get out

 

I actually had my MAF cleaner handy but could not find the sensors anywhere. I suspect they are right above the filters which would mean i have to remove the wheels and liners?

 

You fixed like I would have also, I would have probably just slapped high temp duct tape on there.

If it is running well and not giving any errors why would you feel the need to clean the MAF's?

 

Be CAREFUL with that! If you get some hardened broken chunks later on due to heat and vibration, they can get into the intake stream and cause some damage!
