Checked out a beetle the other day, engine sounded nice when cold but had abit of a rumble when warm, sounded a bit like the generator??
Would this be more likely the generator or main/big end bearings.
I know the easiest way is to remove the fan belt but I had no tools.
Are bigends a problem on them?
It had atwin port so i presume 1600. Year is 1970.
Cheers

Hurry up and wait

It had a twin port so i presume 1600. Year is 1970.

Generator bearings are cheap to replace...

I haven't heard of big end problems...
but naturally it depends on who put the engine together etc

could be a 1300 twin port but 1600 twin ports are more common..
or could be a 1500 with twin port heads...??

cheers

gen bearings are loud when buggered and easy to replace.
