Press submit too fast.
So while I had the valve cover off. I put in new plugs. The old original plugs were really soil. I read a non working pcv can cause that, ie old pcv due to age. Or should I be looking for other issues. Car drives fine. 15 years old 88k currently |

How do you mean the plugs were soiled? Just black soot? Do you see oil on them? White residue? There are many different symptoms and causes. Also, there are some gaskets around the spark plug tubes under the valve cover. I'd replace those too. If these gaskets dry out and leak you'll have oil around your spark plugs. FYI: Some symptoms of a failed PCV (pulled it off a random page via a quick google search) a rise in the pressure of the internal engine failure of seal/gasket leaking oil from the engine emission of black smoke construction of the sludge under the hood wetness under your hood engine surge frequent lean fire oil discovered in the maf sensor increased oil consumption rate Last edited by belcom; 03-29-2022 at 11:29 AM.. |

All the gasket are now new.. everything went back on today and I ran the car with the scanner on.. no errors. The valve area was pretty clean, no sludge build up on the cover or around the exposed area.
Oily plug.. original @ 88k

But before jumping to conclusions, run the car after the repairs for a few days and then pull the new plugs out and check again for oil deposits. Wouldn't hurt to do a compression test on all cylinders as well for peace of mind. |

Yes, all 6 had same issue. the plug well was dry. Once I get the rtab in, ill drive it around and pull the plug after to check. cleaned the convertible drain.. so much gunk in it. Luckily my motor is already in trunk..
I need to get a compression testor.. never own one.
