Coolant magically missing. Can't find a leak

[ScottyDsntKnow]

Lol, epic fail for recommending the $137 "PI" intake on Rockauto. That is the Dorman. Have fun with the Dorman "PI" intake... roofles.





















The CORRECT one is the $215 OEM FORD unit on LRS/AM. And metal crossover or not they all leak. Happens right under the metal crossover where the tstat goes. That piece of plastic is thin and warps, I know, I just replaced one that was like that.

This is what it looked like when pulled:





What the new one looked like:



This is also why I recommend NEVER buying one secondhand as a replacement or for a PI swap. Ppl think "metal crossover=good forever". Nope.


OP, if you did take bad advice and got the Dorman intake, return it. If you already put it on the car... you have another NPI intake.

someone on here (may have been you, scotty) did a write up on the differences between the doorman unit and the ford unit. I was stunned at the differences.
