Sure there might be more issues. Not likely on an NOS short block, but it's possible. Who cares whether it's easy for them or not. You can't leave it that way. It has to be fixed either way. That is the most likely cause. Even if there are other reasons, the intake has to come off anyway, don't you think? BTW, I don't believe he plugged the PCV hole and checked the oil consumption. I think he just wrote that. Sounds to me like he is getting all this second hand and he is not sure of anything.
Speak up young man. BTW, emoticons are there so there are no misinterpretations. What's with the gun?
i was just following the train of people that were screwing with you lol. i think everyone agrees, but they are seeing how many times they can get you to explain what a pcv system does and helps with
So Larry are you going to go around the country talking everyone with 1966 and earlier cars to retrofit PCV valves so they can suck oil fumes back into their engines? A noble cause for the environment, I suppose......:Brow: :bla: One advantage of breathers is that you can see if you have blowby/ring seal problem you can tell easily since it'll be smokin out the breathers. A PCV hides it. Like messin with ya Larry......
No, because those engines were designed differently, with no PCV. An engine that was designed to run with a PCV has a carburetor calibrated to run with the PCV. About 25% of the air used during idle runs through the PCV.. Again, this is a street car. All engines have some blowby. When they get that worn, even the PCV cannot keep up, and the oil ends up in the air cleaner. Last year at Yardley's barbecue, I helped Joe with his street car. His Holley had no provision for a PCV. He was running breathers, and they were both spilling oil all over his engine compartment, getting on the exhaust and smoking. We hooked into his power brake hose (not the ideal), and ran the PCV from there. His problems stopped on the way home. Now I know why Doug loves to call you CHOCK HEAD:laugh: :laugh: :bla:
No, the carburetor is meant to run with the PCV. The idle air passages, and bleeds are calibrated for what you call a vacuum leak. I'd like to see you drive your so called street drag car that far. I'll believe that when I see it.
I actually run a vacuum leak. A stock PCV hose with PCV valve going to a filter....not to the crankcase getting fumes. Nice clean air. Helps the streetability with my Dominator. Actually when I drove up to Etown I had my 925 Themoquad on there with Tomlinson-ported B4B. With 285/70-15 BFG's and 3.73 gears, it was a nice cruise at 65 in the right lane of the NJ Turnpike. I still had the stock tank back then so had better range that the fuel cell I have now. Where were you? Back home playing with your PCV? :laugh:
So you do run a PCV, just not drawing from the crankcase. That's interesting. I thought you had no blowby, so how much cleaner is outside air than your crankcase? What year did you drive down? I never play with my PCV. I can always get a pretty little thing to do that.:Brow: :laugh:
Outside air is more consistant than sucking any fumes that I may have. Makes my car more consistant at the track...... Geez Larry, my memory isn't that good but I had the Stage 2 heads ported by AMP in 2001 so maybe 2002? Here's a timeslip from Cecil with the motor that's still in it....from 2003 after more porting and 4.10 gears, Wildcat and 1050 Dominator. 9.96 132
Bought my GS in 1999. So you did back to back testing of crankcase air and outside air, and there was a difference in your time slip?
What happened to my tread?!:laugh: If I wasn't clear about what we are going to do now, then I'm sorry and will try to explain it better. 1) Gonna test drive the car for 200 miles as it is now (2 breathers in the valve covers and a blocked off PCV hole). And will report back when we have driven that amount of miles, and share the info what we found out. Greetz Robert
OK Robert. I know Bruce feels differently, but I feel that not running a PCV will result in crankcase pressure. That can create oil leaks. I'm not clear on whether you are just pulling the PCV valve out of the intake, and blocking the intake hole, or in addition, you are plugging the hose to the carburetor also. Plugging the hose will make the engine idle slower. The carburetor is calibrated to have that air. Up to 25% of the air used by the engine at idle runs through the PCV.
