I'm in Houston Texas, went to a shop that's been in business for over 30 years.
They tell me I need a PCV Valve and O2 sensors...
There asking thousands of dollars for this repair.
I've had old used cars in the past and I've changed a PCV Valve before and it only cost me, idk 20 or 30 bucks.
? Can I do the pcv Valve myself?
What do I need?
Are the O2 sensors difficult? What tools do I need?
Also the same shop replaced my gas tank along with the gas pump and sending unit.
Please help Scottie 🙏
P. S. I regret not buying a Toyota or Honda 🥵😂
Yes and no it is difficult.
From my POV, actually changing the O2 sensor itself or the PCV valve itself is fairly trivial.
With that said, there are two things that make this trivial task exponentially difficult.
1) Location, location, location. Where is the component located? Is it hidden under a bunch of other components? Or is it relatively accessible? The deeper it is, and the my components you need to remove just for access, the more difficult and more expensive it will be.
2) It’s stuck on. Oftentimes the component is stuck on, either too tightly or because of age/wear/tear. If you’ve never removed something stuck before, it may be difficult. But if you know the tricks to get something stuck off, it won’t be too hard.
I don’t know the layout of your cars engine and components. From the two cars I’ve had to do work on, the PCV valve was HARD because it was hidden behind a bunch of stuff. The O2 sensor was medium, because it was easy to get to, but hard to remove. (I actually had to go to a shop, but now know some tricks to get it loose.)
