Can any one tell me if a 1963 fuel injection motor is suppose to have an oil slinger. I am having a problem with oil leaks at the front seal( i believe )at higher rpms and seems to be a fair amount of oil . Any input on this thanks Steve

The last year that an oil slinger was used on a Corvette engine was 1958. That piece, GM #3704116, was discontinued from SERVICE in July, 1962.In Appreciation of John Hinckley -
Re: oil slinger
found an original 63 service manuel and one of the last steps in the book say to install slinger before installing timing cover . the opinions seem to be all over the place the corvette parts manuel shows this part but the chevy parts book does not . what gives ? i think it should be installed this motor has a pretty good leak with a new seal steveComment

I think that the reference to the slinger in the manual is an anachronism. These slip into factory service manuals from time-to-time. I don't think that any 1963 Corvette ever used a slinger. I don't know of any place you could buy one, anyway.
As far as the leak goes, there could be a whole bunch of reasons for that. The most common is a worn balancer snout (where the seal contacts). Did you check this surface for wear and install a repair sleeve if wear was evident?
Another problem if you did install a repair sleeve is the possibility of installing it "cocked". This CAN happen if you aren't real careful. Also, the sleeve should be installed with LockTite.
Another problem can be a seal improperly installed in the cover. You can distort the seal or distort the cover if this is not done extremely carefully. Failure to get the seal in PERFECTLY will result in a leak.
So, there are PLENTY of things that can cause a front seal leak. The lack of a slinger is WAY down the bottom of the list, if it's even on the list, at all. Believe me, there were LOTS of small block Chevrolets built that never had a slinger. The VAST majority never did.In Appreciation of John HinckleyComment

I agree with Joe, but...
if you really want to install an oil slinger to satisfy yourself that Joe's right (it's not the absense of the slinger that wasn't used after 58-59 that's the cause of your timing cover leak), the part's available in reproduction from Paragon as a 2-piece kit (slinger, 4859 and spacer, 797) for $15.Comment

Re: I agree with Joe, but...
Seems like I remember the slinger was to lube the metal timing chain cam gear. When they went to nylon teeth, the slinger was deleted. Or am I wrong?Comment

Re: I agree with Joe, but...
Seems I've heard that also, but after pulling out several metal chain and gear sets, and even Chevy having the metal gear and chain in some trucks, it could be that engineering discovered the slingers simply were not needed.
And that time could simply have coincided with when nylon gears came out.Comment

I believe that the oil slinger was deleted after 1958 but, I suppose it's possible that it was still around for part of 1959. The first year for the use of the nylon camshaft sprocket on a small block was 1967. When I get around to it, I'll do a post on the "history of Chevrolet V-8 timing sets". I've got several other "promised posts" to get to first, though.In Appreciation of John HinckleyComment

Well, I was taking a shot in the dark.
But I actually thought the nylon tooth sprocket came out well before then but now that you mention it.................................
I still don't think the lack of a slinger has anything to do with this guy's oil leak.Comment
