PCV valve smokey? Wee question from Scotland.
I have rebuilt the flathead in my 32 coupe, now 284 inch, compression is 135 each cylinder so not bad. PCV valve fitted and getting a bit smoke out the exhaust under hard accelaration / 5000rpm. I think this means the PCV valve is working with a dump out the inlet manifold. No smoking at idle so new valve seals seem ok. Any advice welcome. Thanks for looking. Dave |
Re: PCV valve smokey? I don't see how the PVC valve could cause the high RPM smoking. It is more likely your rings haven't seated yet.

Re: PCV valve smokey? Thanks, good point.

Re: PCV valve smokey? how did you get a pvc to work at all?

Re: PCV valve smokey? How often do you spin it up to 5,000??

Tis how most of us drive them, like we stole it. If I put a bunch of work building a "hot" flathead, id spend a good portion of my time trying to break it, after all that's what I built it for. Martin. |
Re: PCV valve smokey? Forgot to add,
Tim, how many miles on this engine? Martin. |
Re: PCV valve smokey? Curious as to what color of smoke? White blue or black.?
|
Re: PCV valve smokey? i bet that coupe runs like a raped Ape!...LOL
|
Re: PCV valve smokey? Smoke is grey, engine is a French block so not a lot of miles on it. PCV valve is connected direct to the underside of the inlet manifold.
Thanks for the advice. |
Re: PCV valve smokey? Grey? Oil is Blue mate.
Keep an eye on it. Martin. |
Re: PCV valve smokey? And too much petrol is black.
Gray smoke? Is it using water? |
Re: PCV valve smokey? Will give it a wee blast tomorrow and check, thanks for the advice.

Re: PCV valve smokey? Found the answer, drive the t#ts of it , if / when engine grenades stick in a 327.
I think that's what happened in1955 too. |
Re: PCV valve smokey? No 327s in 1955, not chevy anyway. :)

Re: PCV valve smokey? Living next door to this man, I can vouch for the fact he does drive it hard and he likes using all the numbers on the tach! It was me that noticed the odd puff of smoke as I struggled to keep up with him on our drive back from the Lake District.
It is a great driving car and don't worry Martin, he will not be allowed to put in a ch*vy, or any of these new fangled ohv engines in it, I will weld his toolbox shut. The smoke is a bit of a mystery, perfect compression on all cylinders, no oil water contamination, no odd noises, to be continued. . . . |
Re: PCV valve smokey? Thanks Gordon, don't ask me to weld up my toolbox as the welds will break...........cant get the penetration these days.
