Re: 305 v6 GMC motor
Hi Dan from Houston. I just bought a 63 gmc with one of these engines and it has a lot of oil in the air filter. Everything I'm reading is saying its the PVC valve. Are you saying it's under the valve cover on the 305 V6?
Thanks Rob |

Re: 305 v6 GMC motor
thanks for the response. the tag in the cab says 305E Engine w/ Certified net H.P. 142 at 3800 R.P.M. I'm pretty sure my PCV is clogged but any help is much appreciated.

Re: 305 v6 GMC motor
Yes those GMC V6 engines are real pulling working engines. that are slow turning and have heavy pistons rods etc. The big problem is they like to consume gas. Ive owned several and in a two ton truck about 4 MPG in a Pk about 7MPG. Remember they where manufactured in the sixties when gas was cheap.If its my daily driver I prefer 250 inline six. if its something that is being worked and need to pull heavy loads I would prefer a 292 inline 6. To me there like a 348 or 409 . Cool looking engines but not very practical and parts are super expensive.
