4AGE oil sump - 5 quarts are better then 4........

[oldeskewltoy]

One of the problems with our hardy little engine(Toyota "A" engines) is they often blow up when they spend too much time about 6k rpm. Part of the reason is when they spend much time up there... the oil pump pumps almost all of the oil out of the pan to lubricate the engine.


The oil then takes its time flowing back to the pan, and the whole process is repeated.

Now if our little engines weren't bad enough with that, they also tend to push some oil up and out of the engine(breather hole-catch can).

Combine the two - and things can go BOOM rather quickly.


One way of stopping this is by adding volume. With more oil in the pan, there is less chance of the pump emptying the pan of oil.

extra sump oil pans are not new... here is one that sells for over $200 in Japan, and this one also requires a collector(extra cost) be fitted





Let me introduce to you my most recent project - A few months back I was asking for old oil pans from folks because I had a few ideas.....















What is new is the design. Each side of the Winged Wonder/Bat Pan pan holds 2 cups(473ml) of oil, 4 cups = 1 quart(.946 liters). Each side is heavily sloped so that oil will always feed the center sump. What is special about this design is the overly simple way of minimizing the oil loss from evacuating the center sump during cornering.... in EITHER direction.


This is the 1st prototype. A few issues have already been noted, for example the drainplug will be moved to one of the rear corners of the main sump, this will allow more complete drainage.

Quote:any pictures of it installed,

Well, now that you mention it........
