Hook up pcv for L79 look problems
Permalink  
 

I thought I had checked everything, guess not.  Evidently the throttle plate for a 66 holly L79 has one little difference.  That being the pcv fitting is for about 3/8” ID hose  The oil fill tube pcv is for about 1/2”, so no hose will fit.    I wonder if it is possible to put something over the throttle plate fitting or inside the hose that makes up the difference?  Any thoughts?

Look up the correct pcv hose for that and it should match the throttle plate size on that end. I'm sure they were a pre-formed hose. NOT sure if they are reproduced.

Well as usual I ordered the wrong part, a pcv for a 66 327 Pontiac.  How did I do that, bad eyes. i bought a nos unit from eBay and it fits.  No preformed hose until they put  the pcv in the drivers valve cover.

Looks like there may be a clip on the carb but maybe not. Probably showed up when they put the pcv in the valve cover
