Partial Flow Oil Change

[Roscomacaw]

Rek,

The way you describe your oil pressure, I seriously doubt there's need to clean that relief valve. It's a bit of a pain to do and with your oil change schedule, I don't think you have to worry about it getting gummed up.

Miscreant at large.

Thanks for the advice. I'll forego the relief valve for now. As the oil, I plan to use Shell Rotella 15W-40. I used 20W-40 last time, but I think it's thicker than necessary and seems a little sluggish when cold (in S. FLA that means 55 degrees F.)

BTW, I have a friend with a 53 Coupe, that has a full flow 289 out of a 64, and it started knocking. He thought the worst...but it turned out that the spring in the relief valve was not correct, or not set correctly, causing the oil pressure to drop too low. Just working the spring cured the problem. We have a former Stude dealer mechanic in our SDC chapter, who has been a huge help to diagniosing problems. He helped me with my starter, which turned out to be a ground wire problem (my starter was fine).

On the subject of lubrication; The damage done to a motor from inadequate lubrication, is for the most part easily avoidable.
Most of the heat and friction damage done to a motor will be in the first few minutes on startup.
The best of the best is an Electric auxilary oil pump, these pumps prime the system before starting and can be pressure regulated, they also get the oil to where it is most needed, at the critical start up
time.
If you want an engine to outlast any other,,,then consider installing one.
I only use a single grade oil,,30wt or 40wt in my Motors, I change my filter every second oil change,,and my oil is crystal clean.
I have never had a failure due to lack of oil, or oil pressure.

My Hawk, with it's mechanical fuel pump, usually takes 4 or 5 attempts at cranking before it starts, if its been a few days. The oil pressure needle usually kicks up during each attempt, so in a round about way, I think I'm getting some lubrication before it starts.

In the HD truck world, there is a gizmo that bolts onto the backside of a 40mt (Delco solenoid mount) starter. It is a small gearoter pump. When the key is turned on it activates te motor, but not the solenoud that engages the starter drive gear (Bendix). This prelubes the oil system. Never have seen one scaled down for passenger cars...yet.

There is another system out there called 'Accusump'. It is a quart sized hydraulic 'accumulator' that gets charged with engine oil from an operating engine and a solenoid closes it off and saves the pressurized quart of oil. When you turn the key to crank, the solenoid opens and a quart of pressurized oil is injected into the oil gassages. Not very expensive. In most speed shop catalogs.

You learn something new every day...
Calvin Lowell (Oldcarfart@aol.com) is an Amsoil distributor, and he pointed me out to the AMS-oiler, a pre-oiler......
Just what we were talking about...
More info here, and it is available at a Stude friendly price from good ol' Calvin!

Hope the info helps.
