Why would a camshaft appear to have the part number ground off ? This is an intake cam. Blue color added to the grind. Not really visible in this photo, but I can still barely read the letter "A" at one end of the blue area. (Everyone knows I have a bastardized ignition system by now, so I might as well expose some more findings.) Thanks, H Image Unavailable, Please Login
Interesting. I have a Euro 308 motor (I don't know the year, as the car was destroyed) It has no emission parts, it doesn't even have the exhaust ports machined for air fittings and the intake manifolds have none of the weird little plumbing on them. It had a single distributor. When I pulled the cams I found the same thing as you. The intake cam for "front" head (with the distrib drive) has no part number, only a machined spot and a blue paint stripe. My other cams part numbers are S109438 S109440 A108989 I don't know if that helps you at all.
I suspect you have a reground cam there with a different profile. Some folks doing a regrind like that will take off the part # such that a subsequent owner isn't led to believe they have a stock cam when in fact they have a custom grind. I'm just guessing but perhaps the blue coating is designed to seal up the ground area.
Glad to hear I am not the only one with a weird and unknown camshaft. Not sure why your three other cams are all different numbers. You'd expect that two of them should have had the same PN. Maybe I'm wrong. I'm not at home this week, but I could have sworn that I had the same PN on my two exhaust cams. (?) Maybe the blue color signifies one particular shop who did this kind of work, kind of their "trade mark" ? H
I bought a set of euro cams for my US '78 GTS. The part numbers are the same as above with the addition of A108892 (for your missing one). I was concerned exactly what these cams were, but it sounds like they are definitely euro (early carbed) cams.
