Q PCV Valve

[Ken]

So my friend just picked up a neglected 91 Integra (after my recommendation) with almost 200k miles for $850, It’s obvious that the car was used as a daily beater for the last 100k miles, but my buddy wants to freshen her up a bit and get some practice wrenching on Honda’s, while going over the engine bay we discovered that someone, at some point removed the PCV valve and just plugged up the hose leading to the intake manifold and then (not even kidding) shoved a cotton ball in the place of the grommet for the PCV valve which was soaked in oil.

Now we’re going to fab an oil catch can tomorrow but wanted to know what harm this might have done, we read that not having it hooked up to a vacuum source will eventually start blowing seals and causing leaks, but other than a bit if power steering fluid theres no leaks after sitting for a few hours.

Also, do we need to buy another PCV valve for our home made catch can?

Thanks for reading!

Its best to restore the pcv system. As long as the hole that housed the pcv is open
you won’t over pressurize.
