Looking for the part numbers for correct '68 L-79 chrome valve covers. Also looking for the smog pump part numbers, same vehicle. Any help would be appreciated.
Thanks,
Mike

Re: '68 L79 Valve covers
Valve covers: 3923226. AIR pump: 7806686 -
Re: '68 L79 Valve covers
Mike and George-----
Yes, however these numbers will NOT be found on the the parts, themselves. They will be found ONLY on the box which a SERVICE part is supplied in. Stamped steel valve covers rarely, if ever, have part numbers on them. AIR pumps rarely, if ever, have the assembly part number on them (although they may have part numbers for the various components of the pump).
Also, all examples of the GM #7806686 AIR pump are NOT the same. All PRODUCTION and early SERVICE have a "whitish" centrifugal filter ("fan"). Later SERVICE have a differently configured and black centrifugal filter.In Appreciation of John HinckleyComment

Re: '68 L79 Valve covers
Mike,
Get ready to pay plenty if you find the parts.
I have the same motor in my 68 coupe and the valve covers cost me $250.00 each from a vendor that we all have heard of and I still need the original smog pump which was quoted at $1700.00 by another well known vendor. Ouch! Haven't bought the smog setup yet and kicking myself for throwing it away in the 70's when I bought the car.

Re: '68 L79 Valve covers
Kurt did you throw away all the mounting brackets or just the air injection pump?Comment

Re: '68 L79 Valve covers
Thanks guys for the info. Is there a way to tell the difference between repo and original valve covers? Isn't there supposed to be an "O" or something stamped into the flange area? Also, would these part numbers be the same for all L-79 motors whether they were installed in a Vette or Nova or Chevelle?
Thanks again,
MikeComment

They're the same for all L-79 regardless of chassis installation but ONLY for the 1968 model year. They're also the same for 1968 Z-28 Camaro.In Appreciation of John HinckleyComment

Re: '68 L79 Valve covers
Mine have one enlogated "o" in the center of the lip (area that bolts to the head). G.Comment

Jim,
I only have the cast iron bracket that mounts on the right side/top of engine next to the A/C compressor. Everything else got tossed in 1972.

Re: Another little known fact...
...the production '68 L-79 valve covers are not the same as "new ones in the box". Production ones did have that "elongated" "O" on it's side on the upper flange, but they also DO NOT have the "lip cut-outs" for possible aluminum intake runners. Service replacement & NOS ones will have this, while ORIGINAL PRODUCTION valve covers will NOT. Most judges don't even know this.Comment

Re: Another little known fact...
Hey Paul,
Well you ruined my weekend. (Just kidding)
I just took my valve covers out of the box that I purchased in 1997 for $250.00 each and they have no elongated "O" anywhere and they do have the cutouts along one of the flanges so I guess Paragon screwed me big time. They assured me they were selling me the correct original L79 valve covers. $500.00 screw job, buyer beware. At least they're pretty. Live and learn, I guess.

Re: Another little known fact...
Kurt, those are still very, very good valve covers-probably the closest you can get to being "original" without being original. Remember, many, if not most service replacement parts/NOS parts were slightly different than the production line pieces they replaced. Now, 'bout that finned balancer.....
...not to ruin your weekend any further, I got those EXACT valve covers you got at a local swap meet for twenty(yes, $20)for both from a seventy year old man who forgot what they fit. Of course I played dumb & said they'd look nice on my '71 307ci Nova!!!Comment

Re: Another little known fact...
Funny thing about that finned balancer.
Have you been looking in my checkbook?
I bought one for $300.00 and the guy at the machine shop that assembled the motor had never seen one before. I have it on my motor now and have the old non-finned as a "spare", like I might live long enough to ever need a spare.
They get to much for some of these parts but I gues my stupidity comes at a price since I removed the original parts and "customized" the car before i knew better. Learning about NCRS was a costly education, believe me. Now I don't ever throw anything away again.
