Why in the hell would you drill a hole in your intercooler? You're now venting out un measured air and causing a vacuum leak.

The air hasn't been metered at that point...Not a vacuum leak but a boost leak. Luckily for the fools who do this,  the car meters the air via the MAP sensor for primary fueling...It's the only reason this mod works without throwing things out of whack.....No holes in my pressurized system though.

That's right I forgot, I'm so used to tuning my ancient MAF cars. :)

Anything wrong with drilling a hole in the inter-cooler and thread a bolt in there, then remove it every two months on a dry day drive for 20 miles then screw the bolt back in.

Any thoughts would be appreciated!

Drilling a hole through a part in the intake track is nuts.  You'll never properly remove all the metal shavings.

I would just invest in a good suction type air compressor and have her suck it out while the front drivers side is elevated,had mine performed at the dealer for free,found roughly half an inch of oil and h20 mixture inside.  Z    https://www.youtube.com/watch?v=urMO7Z5d02k

Now that I have some miles on this, the car is definitely more enjoyable. No acceleration issues and it feels much better.

Still going strong with this mod. Plugs are staying nice and clean, power is back, and gas mileage is up.

93cobra, is the car still running strong with the weep hole? Any issues?

I've seen this "fix" mentioned a lot on the F150 forums in the past. SMH

It's easy to occasionally vacuum out or back flush the CAC, so I will never be drilling my intercooler.

About 3 weeks ago It began, the dreaded sputtering after a long day at the beach last thing i want is car problems,
check engine light was flashing & then it became solid, the next day the sputter was gone and so was the CE indicator.
a week later the sputtering began again with flashing CE, changed plugs to Autolight iridium plugs, I ordered 6 Accel coils thru Jegs but had to send them back because those had 3 pins our clips have 2 pins I
sent them back and purchased Motorcraft from Ford dealer, after installing sputtering continued, after i did some reading and watching some videos in went ahead,  drilled a 1/16 hole to the bottom of the intercooler,
a large amount of thick oil drained out, I drove around the block 5 times, parked and left it Idleing for 10 minutes, this morning I started  my car sputtering gone , it is smoother then ever before.
I read that quite a few of you guys are against that drilling but just wanted to let you all know it help me, CE light still on tho do i need to get it flashed at dealer? any suggestions?
oh, ill post pictures asap.

Can you add your vehicle information? (year/model/mods/possibly mileage)

Depending on the codes present, they may just need to be cleared out, other may need further investigation.

The CE light usually stays illuminated with any code that is set. Most likely a clearing of codes will remove it.

As for the drilling, glad it helped you, though I bet cleaning the intercooler out without drilling would have achieved the same result.

Only time will tell if that was a bad thing to do, thanks for your inputs
I'll attempt to install a drain plug to the PTU.
And good write ups for that job?

There are writeups for the 6F50 PTU, but not the 6F55.  AFAIK, you'd be the first to install a drain plug on this PTU.  IDK if the 13+ Perf Pkg PTU can be used as a guide as to where to install the drain plug.
