Steve's Nova Site is an automotive enthusiast website dedicated to the 1962 - 1979 Chevrolet Nova, Chevy II and Acadian automobiles. We work together to preserve, restore, drive, show, race and provide fellowship for these classic cars. This is one of the best places to find information about parts, rebuilding, restoration and racing. This website is not affiliated with GM, General Motors or Chevrolet in any capacity.
It also appears that from Page 258 (below) the vent tube is not supported at all with a bracket mounted at the Carb stud. I think this confirms that the correct routing for the vent tube is through the bracket (Part #3877445) mounted at the thermostat housing and through the bracket (Part #3877445) mounted by the Valve cover hold down bolt. Thanks for everyone's input!

Hey guys, in our efforts to make our cars correct, let's remember we're dealing with the 60's where the only consistent thing was inconsistency. Not all things that appear in assembly manuals necessarily happened, and many that did got changed over the course of the production year. Brackets and fasteners that appear in these books may have been quite different in reality, or may have changed as the year progressed. There are L79s that didn't have the PCV bracket on the thermostat housing, but as we've now learned, some did. There were things that were different on Canadian built cars and even different from plant-to-plant in the U.S. I'm from the school of 'anything was possible' and I don't adhere to 'my car has this, so any that don't are incorrect.' Yes, all 1966 L79s had chrome dual snorkle air cleaners and most have 3245 carbs underneath, but in the mid 80's an L79 guru had an original with a 3806. I guess what I'm saying is, we shouldn't get too caught up in 'absolute correctness,' because what was correct on one car may have been different on another.............but still correct.

Yes, all 1966 L79s had chrome dual snorkle air cleaners and most have 3245 carbs underneath, but in the mid 80's an L79 guru had an original with a 3806.
In Tom Migut's article on the '66 L79 written for the May 1985 issue of Nova Times (Volume 4 Number 5), he states that the correct carb is the 3806 - and makes no mention of the 3245. There are only two photos of the carb in the article and neither provides much detail. The vent tube for the rear barrels does appear to be different, though. While the article is reasonably accurate, it's apparent that he didn't have access to an assembly manual for reference.
The article also shows the PCV valve turned the 'normal' way. There is no bracket on the water outlet, but there is a small bracket that appears to attach to (or near) the passenger side front carb stud. It is similar to the one in Jerry's photo, but not exactly like it.
We tend to forget, too, that these cars weren't as reliable as todays vehicles. Lots of original parts were swapped out within the first year. A 2 or 3 year old car could have all kinds of parts that weren't original.

Add to that the prevalence of owners swapping out parts themselves or altering the cars even when they were still relatively new. And the great interchangeability of parts. I know with Oldsmobile back in this period the wagons had better carbs, exhaust manifolds and sometimes heads. A simple swap and now you have legit factory parts, added with little to no modification and everything looks as it should. A scenario that could easily fool people into thinking everything was bone stock.
this setup was out of my buddies L-79 66 nova ss, car had been apart since
1974 has 3806 carb. this motor is in my 63 hardtop when I purchased it was
in boxes. this my effort to bring it back to it's former glory
Guys;
Nice pictures of the engine posted. Can I get an AC Number on the PCV
Valve and info on the hose that is correct for the 66 L-79's?
Thanks
Ken Joseph
I am not here to pick apart anyones car but have been working on my car for three years now. I have asked many questions and received very good guidance from many very knowledgeable L79 experts on this site but the following is incorrect
"In Tom Migut's article on the '66 L79 written for the May 1985 issue of Nova Times (Volume 4 Number 5), he states that the correct carb is the 3806 - and makes no mention of the 3245. There are only two photos of the carb in the article and neither provides much detail"
The correct Carb for the L79 is the 3245 also, the PCV routing as shown in the assembly manual and from the original brackets I have "can be correct" as shown in prior pictures with hose bracket mounted to the thermostate housing. The pictures provided in the last post should not be used as production correct L79 reference from information I have received.

Tom, there is every indication that some 1966 L79s came with a 3806 carb. Chevy by the Numbers notes this carb may have been used in Chevy IIs. In addition to Tom Migut's article, I've heard of one other that had a 3806. I don't know how it can be proven 100% that these carbs were factory installed, but because it was the 60's, we also can't say 100% they weren't.

Bob, my point exactly about the PCV routing, I take it as correct to rout it through the bracket on the thermostate housing. Infact, look at Barrett Jackson Lot 954, a documented 1966 L79 Nova SS engine pic that has what I believe to be the correct hose routing. About the carb? that is a quote from NovaJoe..........I dont have enough info to debate that, but I agree, 60's
