Extended Storage question

[LEEJANDZ]

I was flipping through the restoration manual for my 79 L-82 and I came across this.

In the event vehicles are to be stored for an extended period beyond 30 days, the following items are suggested.
1...
2. Start and run engine until completely warm.
Drain engine oil and replace filter element, refil with fresh oil.
If the vehicle is equipped with A/C...

A. After the oil has been replaced, remove air cleaner AND POUR 1/2 - 1 PINT OF 10W OR LIGHTER OIL INTO CARB AIR INTAKE WITH ENGINE RUNNING.
POUR SLOWLY AT FIRST, THEN RAPIDLY USING LAST QUARTER TO STALL ENGINE.
Replace air cleaner.

I have never heard of this before.
Can anyone shed some light on this situation?

:confused :confused :confused

That is pretty wild.

No doubt that would leave a nice coat of oil inside everything. For just 30 days, I think it is a bit of overkill.

What if you were to do store the car over the winter?

I still dont understand the logic in this process.
Can you explain it to me?

Why dump oil into your carb while its running?

dumping oil into the carb is an oldtime trick for car care....going WAY back.

In fact, you can also dump a blend of water and auto trans fluid in the carb to clean carbon deposits out of the combustion chambers.

This method will soak the cylinder walls down, lubricate the valve stems, and leave a wet sticky coat of oil residue. This will help slow down, or prevent rust from building up inside.

Many people will pull the spark plugs, use a tube and funnel to put oil in the cylinders, or just use a spray lube.

If done right...it is a wonderful thing. If done wrong, you can do some serious damage to your engine----ie, the liquid does not compress and you bend a rod/valve.

I guess this is not a common practice here in sunny Southern California.

Is this something that should be done regularly?
Should I try the water/ATF to clean out my combustion chambers.

Only under supervision from a qualified mechanic...or just an old timer that has done it before.

What is better, go to your local Chevy dealer and look for a can of GM top engine cleaner. It is a specialized blend of chemicals made to be dumped in the intake while the engine is running. It will do wonders for cleaning out the combustion chamber. You will be amazed at it, or the atf/water method at the amount of black crud that blows out the pipes.

I poured a can of GM Top Engine Cleaner down my carb last weekend. Make sure you do it in a well ventilated area(not in your garage). Your neighbors might not like you for a while afterwards,that stuff stinks to high heaven when you blow it out the exhaust.. That stuff works very,very well like Chris said.

So this is something I can do here at home.
Was there a noticable difference before and after?

Top Engine Cleaner

It cleans the carbon deposits out of the combustion chamber. I use it once a year. My motors pretty clean so I don't notice a big difference,but if your motor has alot of carbon deposits it would make a difference. Give it a try,the GM# 1050002 is what you're looking for.

What is the MSRP?
And can you only get it at a dealer or at my local auto parts store?

$5.30. I have never seen this at an auto parts store. Any GM dealer should have it. It's a good yearly maintenence item.
