Cracked intake tube

[tfunk88]

Sooooo found that the bank 2 “rubber boot” as BMW calls it…or the intake tube, as I call it…cracked where it mounts to the turbo on my 50i. Which is letting some air in post MAF and filters. I’ve ordered both bank 1 and bank 2 replacement tubes from FCP Euro. How bad is it to drive the car until they come in Wednesday? No engine light but when I pull codes I’m getting stored “bank 2 lean” codes. Have been driving it like this for a bit already, just discovered the crack. 🤦‍♂️

Considering that allot of us are driving around with these things cracked and don't even know it. Probably not a good idea, but ...

Did you try some JB weld? Re the //M Sub.

Interesting…I may try that on the replacement tubes to keep them from breaking in the future

Nah, nah. Try JB weld up the current cracked one. Just to seal it up so your not sucking unfiltered/metered air.

I’ve got it rigged up so that it’s tight for now, and I’m going to try not to drive it until I replace the tubes. I like doing car work, but I’m not pulling all that stuff out twice…I’m lazy lol

Replacement tubes were only $120 and come with a lifetime warranty, so I’m def going that route.
