[Healeys] FW: Oil again

Tue Jun 23 21:02:47 MDT 2015

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.
