I have an '68 beetle 1600 air-cooled engin, build into a buja bug. There is an oil leak behind the main pully. What is the problem, and what has to be replaced?

Thank you.

This happens when the O rings to the oil cooler or the oil cooler goes bad you will need to remove the air fan assembly to get to it.

Please let us know if you need anything else to get the problem fixed. Cheers

Hi there,

More than likely this will be push rod tube seals, but check rocker cover gasket as well as this is a quick check and fix.

My bug is leaking oil between the engine and transmisson when running a steady stream. I have replaced the rear main oil seal the gland nut and lock washer & the o-ring in the flywheel but it is still leaking. What am I missing?

Hi there,

you will still have problems if the seal surface was marked or there is excessive end float in the crank shaft.

You can do this in situ you will have to give the engine a good wash down underneath first, with the engine cleaned, it will be easier to see any fresh oil leaks developing.

I have a 1970 vw beetle. 1600 carburated 4 speed, my wife had to have the cute car. After driving it for a while smoke comes out of the engine compartment. When I open the engine compartment it seems to be coming from the right side near the firewall or fan shroud. It's as if someone spilled oil on the motor and it is burning off. There are some oil drips but no major loss of oil that would suggest and oil leak onto the case. Any ideas? The heater seems to be letting in exhaust but I think that must be a problem with the heat exchangers and/ or hoses

Valve cover gaskets or tube seals. Have a shop check it for you. They are pretty simple to repair.

It has to be oil. There is no coolant. I agree with ASEmaster8371. Most likely the valve covers.
