Vaccum Leak at Inlets?

I'm doing a carb overhaul soon, I have a small vaccum leak, and it is time to do the carbs. But, on cylinder 1, the rubber inlet seems to have small tears in it, do you think I should replace it, or is it just normal for old plastic/rubber.

It also seems to be leaking a tiny bit of oil from the inlet.

Thanks for Any help,

Cracks in intake boots 30 yrs old are fairly common, and there are threads dealing with sealing them. I've seen liquid insulation and liquid gasket suggested as well as using a piece of inner tube to wrap it with. I'm sure someone will post those threads.

My leak was not the the small cracks, but the intake boot gasket. I have no idea why a gasket would go bad, but mine did and when I removed the intake boot about 1/4 of the gasket was gone.

Not sure what to think about the intake boots leaking oil.

 

I had a similar issue as far as leaky gasket. In the end I removed the bolts, chased the threads, made new gasket, replaced bolts,tightened it down and still did not work...


Take 2- added gasket maker/sealer/what ever that black crap was in a very fine bead around the mating surfaces before final assembly, tighten it down, let it cure and BAM! No more leaky gasket..

Symptoms prior to investigation were vaccum leak symptoms.. Problem was isolated using engine start spray with a red tube attachment and spraying a little here a little there until I found the sort that made the engine rev up.
