The early years

A project log for Marvin

Our baby boy is all grown up. Perhaps it is time to send him out into the world.

The old engine bay. There are many photos from before this, somewhere else. 

This one was taken at the point I was already planning to remove everything up until the firewall. I wish I had kept that blower. That would have made some of what is to come a bit easier.

The 67hp was actually ok to deal with unless you were fully loaded and/or trying to climb any kind of grade whatsoever. You can also kindly forget about ever towing anything substantial.  Of course the times you were fully loaded were the times you were most likely to be doing said grade climbing. 35 wide open in the slow lane.  You could feel when you were all alone.  It was spry by comparison then.

I really wish I had captured some before and after numbers now. I'm sure Google has collected this information for me on a similar build if I looked hard enough.  Perhaps I will look hard enough some day.

Squirrel.

Anyway, what really did it for me was the eventual consumption and leaking of somewhere around a gallon of oil per hundred miles and the subsequent danger of randomly going up in flames at the end. This also got intolerable once the back window started needing to be cleaned multiple times per fill-up to even be usable.

Leaking that much from so many places could really not be a good sign. When the oil starts to leak from many places at once that engine crank case is operating at positive pressure now.  That is a lot of blow-by to be able to overwhelm that huge black  ~20mm PCV valve above on the lower left. That crankcase should have been perfectly balanced.

It still ran fine and was not really at a loss for power yet as long as it stayed cooler. We started to leak onto the manifold though while on the return trip from Minnesota to Ann Arbor, MI. 

When we returned I asked a friend if I could borrow his garage and I dropped that engine without ever cracking it open. I imagine it's probably still..

Now, perhaps I should formulate a plan.


I do believe the oil leaks, and other excess lubricant never cleaned from most parts along with other protective foreign matter which we will get to later, contributed greatly to the preservation of the body.  It has the original battery trays.... so there is that.
