[Vwdiesel] oil squirters

[lbaird119 at aol.com]

  I did the modification to the Dasher, which has an oil temp gauge.  The way I was able to 
determine that they "worked" was I noticed that the oil temp would start to rise, under load, 
on a piece of road where it didn't before.  It was obviously picking up more heat.  How well it 
did or how necessary it is, I really don't know but there's my "scientific proof."  :-)

Really, if you get oil anywhere near the bore and it splashes on the
rankshaft, under 2000rpm-ish you get a bit of windage, but it should fling
ust as much in the vicinity of the piston as anything, and accomplish what
ou're after because of all the air whooshing around in there.  At rpm, I
on't think piston cooling jets do so much squirting a jet of oil at the
iston underside as act as an aerosol to get droplets of oil in the air- a
urbulent suspension that eventually gets splattered onto the piston as the
ir on the piston underside pumps back and forth from bore to bore.  Having
ooked at the bottoms of td pistons, they don't look very directly cooled,
iston cooling jets or no. They look very blue, baked, coked oil, but not
verly cooled to any great extent...  Not to say the piston cooling jets do
OTHING, probably carry more heat away from the piston skirt than the
nderside of the piston.

 Depends...
 If you have a newer block, with bosses for the squirters then I suppose
ou could.  It'd involve facing, drilling, probably reaming and then
rilling and  tapping the mounting bolt holes.  If the bosses aren't there,
here isn't enough meat to do it.  I'd intended to do just that but there
asn't enough material to install any so I did something that works just as
ell but requires a bigger oil pump.  
 I drilled angled  holes from 4 of the main bearing saddles.  I aimed for
he middle of the piston when it was about mid travel.  I drilled most of
he way with about a 1/8" or slightly larger, bit. 
hen I finished the last 3/8" of the hole with the same size as the oil
quirters have.  Don't remember what that is now.  I tested them with a
arden hose while washing out all of any metal filings.  I was quite happy
ith the results.  If they didn't work then all I had to do was not drill
il access holes in the bearing shell, that would provide oil to the
squirters."

an oil squirters be installed on a NA block if the corresponding space on
e NA block is faced off to allow for the squirters to be installed like hey
re on the turbo block?
