No, a clogged PCV will cause seals to leak due to crankcase over pressurization.

The inter cooler collects water vapor and oil fumes. If the leak is at a flex joint, replace the flex joint as they get old and porous. Make sure the clamps are tight.

The older versions of the T5 engine had a weep hole to let the oil/water mix drip out. This usually resulted in the liquid dripping on the splash pan and running down the pan to the driver's side before dripping on the ground.

Because this only happens under boost, I drilled a 1 inch hole in the splash pan directly under the weep hole. This allowed the fumes and liquid to drip directly on the road rather than collect on the splash pan and leave spots on my concrete garage floor.

Some Brickboarders suggested taping an absorbent cloth (doggie diaper) to the splash pan and replacing it every other month or so. That is more work than drilling a hole.

Keeping it running is better than buying new
