[Mg-mmm] J2 oil filter

[Bob Grunau]

Howdy Bob,
Yes the old wire mesh would be redundant. And CLEAN oil reaching the
bearings. I think it is OK to make the engines last longer by suppling
filtered oil. Shoot, would you drink a beer with sand in it??
As for the concours guys, hmmmmm. how many of us have 100 point cars?? We
like to DRIVE 'em. So what does it matter that the 1/8" BSP connection has
been changed to a 1/4" NPT??

What address should I send the oil filter adapter to ??  :-)

Now if spring would ever arrive here in Ontario, I might get the PA out.

J2 now has starter filtered oil pressure, so maybe an engine start soon and
that will encourage further work on the car.
Best regards, Bob Grunau

	You mean I'll have to abandon my MICRO(the one with quarter inch
holes due to corrosion that resides, or  should I say sags in my
crankcase) filter I now have?  I won't have to change oil as often,
then.   I have a sad feeling whenever we alter the looks, both
technically and artistically, of our original vintage cars to make
them last longer. but I'm sure it is more and more necessary as time
moves on.   Some 'do goody' Concours 'Inspecty' will look and say, Oh!
Oh! that's a 1/8th fitting where it isn't supposed to be.
