Here is my answer to the grommet problem if you can weld, and don't want to order and wait on a dsl00143. Go to the hardware store and find a 3/4" carbon steel pipe coupler that fits snuggly in the grommet. Then cut off the small end of the pedestal that goes into the grommet cut the coupler the same length and weld it on where you cut off the other piec,e and you can use a n/a CDR grommet with a factory/ats turbo for less than $2.

 

Update no blow by getting by the grommet nice tight seal

 

theres a doorman part that works for the turbo drain grommet. at any parts store for like $3-4. i dont remember the part number tho. i think its for some random car engine and just happens to work.

 

When me and the guy at the store were looking nothing in store had a big enough OD. And the catalog did not have measurements just pictures.
