Oil Foam

This may be a stupid questions but I have a smal amount of foam inside
the oil cap on my 2005 Toyota Tundra. Is this normal? The truck is
running great but when I had the oil changed I was told it could be a
problem.

I just looked at the oil cap of my 2005 Tundra and I have the same thing.
I'm taking it to the dealer tomorrow for a fuel pump issue and I'll ask them
about it and post what they tell me.

The fuel pump problem was posted by me on 3/21 and I got the following
response:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Could it be TSB EG043-05 9/28/2005 - Toyota 2003, 2004, 2005 4Runner &
2004, 2005 Highlander and Sienna & 2005 Seqouia, Tacoma and Tundra. Some
customers may experience a "no start" condition and/or M.I.L. "ON" with
DTCs P0300, P0171, and P0174 after the vehicle has cold soaked in
sub-freezing ambient air temperatures. To correct this condition a new
fuel pump sub-tank assembly is now available. Follow the repair procedure
to replace the fuel pump sub-tank assembly."

Foaming oil is often an indication that antifreeze in leaking into the oil
system; possibly through a bad head gasket. Get it checked.

I spoke to the dealer today and they said their parts manager has a 2005
Tundra also and saw the same foam. He immediately thought "Head Gasket".
They said it's nothing to worry about and it went away after his 3rd oil
change.
I just did my second oil change on my 2005 Tundra, I wiped the foam out of
the cap last night and it hasn't returned yet.

Be very sure that the oil was not over filled.This could cause it to
foam.
Good Luck....

Are you suggesting that some mechanics might be confusing quarts with
gallons, especially if they work at those instant oil change places? How
could that be? :-) :-)

From what I've read the strange oil near the inlet and cap is a common
issue with this engine. Also, from what I've read, it seems to happen
more in the winter, especially if the engine is used frequently for short
trips. I guess water has a tendency to condense there?

Actually this foaming around filler cap and crankcase vents is common on
most engines. Usually, unless there is a large amount of foam it's not
indicative of a problem.
