[Healeys] FW: Oil again

Tue Jun 23 22:25:36 MDT 2015

Hi Bill. .012 is a long way out! Make sure you don't end up with pistons
coming up above deck height. If you already have a rear main seal
conversion, check firstly that the rear engine plate is flat, they are quite
thin on the 100. Also you will see when you get the rear plate gasket, the
gasket may have 2 extra holes across the bottom that appear to not be
needed. Some blocks had 2 extra holes across the bottom to hold the rear
engine plate. The addition of these extra holes and bolts can help seal the
engine plate and stop leaks that can appear to be rear main leaks but
aren't. Also when fitting the new head gasket it's worth using a little (
very little ) sealer on the gasket down the spark plug side as the water
galleries are very close to the edge of the head, so often you will get a
very slight water weep from the gasket.

Cheers

Aw that's nothing. My car has always leaked oil profusely even though I
thought I had covered all the bases the last time I rebuilt it. Lip seals on
both ends of the crankshaft, careful fitting and Hylomar on all of the
exterior gaskets and the rear main bearing block. It still wouldn't hold oil
(or a head gasket). Now it is down again (broken pistons on #1 and #2) so
I'm doing a total rebuild. The first item of business is machine work on the
block and the machinist said (roughly) that the top of the block resembled a
ski jump, one corner was 0.012" higher than the other. I guess because of
that I couldn't get the gasket to seal around the oil passage and all the
oil was running out of the head gasket and down both sides of the engine,
not to mention contaminating the coolant system. Looks like some select
vendors will be separating me from more of my money...

Ya know oil doesn't stay in my car very long anyway to worry about.
Seriously,  I found the problem m The back of the valve cover was flat, plus
the gasket had slid forward

Greg, I don't think the brand matters much. They all have to meet the API
specification. I think all the rest is marketing.

Thank you Bill, although it doesn't tell me which brand to pick, your clear
explanation of the oil codes and changes in formulation give a very good
background for someone trying to muddle through the oil choice issues
classic car drivers face these days, and understand why oil
choice/availability had become a significant issue.

I see I'm late to the party on this topic. I was up in the Rocky Mountains
participating in the Glenwood Springs Rallye when it started and frankly I
wish I still were. However, at the risk of being called ignorant,
uninformed, commie pinko or whatever I have a little information that may be
of help in sorting out the oil confusion.  

Engine oil comes in generations as defined by the additive packages which
are blended in to tailor them for specific purposes. These generations can
be traced by the API codes which are located on the container. 

The API code is two letters found on the label. The first letter is either a
C, which denotes the oil is intended for use in a compression ignition
engine, or an S which denotes it is intended for use in a spark ignition
engine.

The second letter denotes the type of use intended and follows the
development of the internal combustion engine from the most primitive (A) to
the most sophisticated (I think they are at O Now). protective amounts of
zinc were dropped from the additive package at SM. Any oil before that, or
say from SD through SL, still contains zinc.

It may be true that zinc is not necessary for engines after the camshaft
break-in, but I prefer to be cautious on that score so I look for oil that
is SL or earlier. I'll let the more informed and adventurous members conduct
that experiment...

Some heavy duty oils such as Chevron Delo or Rotella are rated for both
compression ignition and for spark ignition service and will show both a C
and an S rating. In some cases those oils will still have an SM or later
rating.

The one oil type I have found that is reliably rated below SM is four stroke
motorcycle oil because motorcycles don't have catalysts. Typically it is
rated SF or SG. Since the oil has no way of knowing it is being run in an
automotive engine and my Healey doesn't know the oil it's spewing is meant
for a motorcycle I have been running Castrol 4T in 20W-50 grade quite
happily.

As for the controversy part, if we start banning contentious topics we soon
won't have anything to talk about like most modern college campuses.

We ALWAYS talk about oil and no one seems to have the answer, so we simply
keep talking about it.  

For a change let's talk about politics or religion, two topics which are
susceptible to absolute rectitude. Many or most of us do not have the
correct answers on either and someone here--perhaps an unknown lurker--may
choose to now come forward with his or her enlightenment and reveal it to
us.  

To mix a metaphor, I now listen with a jaundiced eye.
