from the oil filler tube! I know the engine is mechanically
healthy, as I rebuilt it.

I have a pcv installed in the topof the block. (not the valley pan). the road draft tube has been eliminated.(blocked off). I understand, the

oil filler tube also acts as a fresh air intake. but, something I'm not doing right, because there is too much blow by thru the filler tube, thus fumes are getting into car..

I know all you guys are extremely sharp! so, I'm sure
someone has a fix.

thanks!!
Can you show a photo of the PCV SYSTEM install?

If she is pumping fumes out of the filler cap, it is either non-functional and/or has extreme blow-by.

It so warmed my heart to see her face melt in sweet appreciation ...

‘Somewhere I haven’t been in a long time!’ she said.

So I suggested, ‘How about the kitchen?’

And that’s when the fight started ....
