This raises a lot of questions. Good luck to the owner. I just wonder IF there is a “shady” mechanic that maybe put the steel wool in that line?

The mechanics that replaced the previous 4 engines should be ashamed for ripping this guy off.

I bet the first engine had blow by and was spitting oil out the vent line so some dummy put steel wool in the line to “baffle” the oil passing through it (dumb). Then the oil vapor hardened in the wool over time causing the complete obstruction. Just a wild guess but crazy enough to be true. 🤯

Who would spend so much money on one car to replace 4 engines? Are they all was for free?

dave should post a video saying sorry for giving the tech attitude - it wasn't deserved and in the end the tech was right and the shop owner was wrong in multiple ways - I'm currently dealing with a shop owner with an attitude also - 99.9% of the time most tech's are right

Dylan definitely humbled Dave here. In a different video, Dave thought it was blowby, but Dylan was right.

I had that same problem with a truck I bought. They couldn’t figure it out. Tape clogged up the vent line. It also pushed the rear main seal out, so check for leaks on the seals.
