One last tidbit

Before installing the pump cover, I always lubricate the inside of the pump with either liquid hand or laundry soap. It does two things, first, it tends to close small gaps which will increase it's...

The short and "long, long, long answer"

The short answer is yes, the alternator does turn in the same direction as the flywheel. Now for the long answer. Recently, while mocking up an engine for another application I found that, because...

"Dental floss?"

Recently, while doing some work on a friend's boat, I discovered a very creative way to make an "O" ring of sorts. Someone had wrapped about 25' of dental floss around a shift lever shaft that...

Firing order quiz

If you don't already know why the firing order is 1243, do a little research on the "flat crankshaft" and impress your friends on the dock. Almost everyone has made the firing order mistake at least...

PCV?

One element that has a direct affect on the idle capabilities of an A4 is whether or not it has a PCV system. If a relatively healthy A4 has a clean carb and has been set to factory ignition specs,...
