Spark advance problem – Datsun

admin — Tue, 21 Feb 2012 00:35:41 +0000

I need a showing of hands from the Z-car owners on the list. How much
total advance does your L-series distributor put in OVER the base timing.
I have an electronic unit that is advancing 30+ degrees over my base
setting!!! The vac should be good for 5-6 and the mechanical should be
good for 10-15. But not on mine. I have a ~11.5 cr so I only need about
30 total. What do you guys have for advanace over base numbers?

Manual trans fluid

admin — Tue, 21 Feb 2012 00:35:20 +0000

I am playing around w/ using synthetic engine oil (0w-30) in my manual
transmission. Realizing that Borg Warner is now reccomending ATF (aka
Dextron III) for the T-5 and T-56, I am wondering if anyone is taking this
as a time to re-evaluate their trans fluid? The reason BW is using
Dextron is due to the syncro rings, and the cold start tollerances of the
bearings and housing. They basically needed somthing that flows at low
temps and doesn’t hurt the paper backed syncros.

Using the 0w-30 will be easier on the sycros, improve shift feel. Plus
engine oil has just as good as EP (extreme pressure) addatives (aka zinc,
and sulphur) as gear lube. Your unit loading of a flat tappet camshaft is
much higher than what you see in a trans anyway. I can’t see any obvious
reason why you wouldn’t want to run a lighter oil. Any comments?

FREE tool for car clubs

admin — Tue, 21 Feb 2012 00:35:00 +0000

Since I announced this a month ago, I’ve GIVEN away thousands of sets
of a tool called Snap-Ups, which makes installing an
engine oil pan and gasket an easy, safe, one-person operation. They’ve
been reviewed and praised by national mags including Popular Hot
Rodding and Skinned Knuckles. They were sold for several years thru
the Eastwood Company catalog at the retail price of $7.95 per set plus
shipping.

Not that many left, so respond NOW if you want some.

I manufactured these myself for several years, until the license to
produce Snap-Ups was purchased by a major gasket manufacturer. They
now package a set of four Snap-Ups with every molded oil pan gasket
they make.

I was left with a supply of the original Snap-Ups. They fit every
known American car. I don’t want to get involved in the effort of
selling them, so I’m willing to give them away!

If your car club is a Not-For-Profit organization, I’ll send you as
many Snap-Up sets as you’d like, to distribute to your members. Some
clubs are using them as a membership promo. Others are putting them in
volunteer ‘goodie bags’ at shows. Still others are distributing them
to members. Your imagination is the limit.

So. . . pass this message on to the head of your car club. E-mail me
the name and address to send to, the name of the club, and a
statement that you are a Not-For-Profit organization. I’ll send you
any quantity you need. Minimum 24, maximum 500, in boxes of 24 units
each. They’ll be shipped UPS Collect, for the freight. (They’re very
light!)

No catches, if you meet the above requirements. What’s in this for
me? Emptying my storage space, helping the hobby, and maybe a
charitable tax deduction. Hurry now; there’s a limited quantity and
the offer ends when they’re gone.
