Newby Question:

If I need to "flush" my engine. Am I actually looking for something called "engine flush," or is that a generic term?

 

It is a generic term. There are products formulated for just this process, like the one made by Gunk. But others will achieve good results by draining 3-4 quarts of engine oil, add the same amount of automatic transmission fluid back into the engine ---and let it IDLE for 20-30 minutes before draining the entire amount, and fitting a new oil filter and engine oil. An excellent additive for petroleum engine oil is Rislone. You add the entire quart at a oil change (normal capacity of a Rover V-8 is 6.5 quarts --so use 5.5 quarts and the one quart of Rislone). This keeps things in tip-top shape.

P.S. When I say run the engine at idle for the 20-30 minutes, I mean just that. Do not drive the vehicle with the ATF in the engine, as it is not a lubricant meant for heavy loading of bearing surfaces.

I just had the 45K service done at the dealer, so I'll have to wait about 3K miles to do it. Thanks a ton. I like your site, it's very helpful.

 

I never heard of putting the trans fluid in the engine. It won't harm it? How does risoline differ from seafoam??

 

Pasted in below is ad copy from Rislone and Seafoam. Read --- and form your own conclusions.

Rislone Engine Treatment® is a high quality lubricating oil combined with protective engine additives and unique engine cleaning additives. Its multi-grade formula allows the oil to flow freely and provides protection over a broader temperature range. Rislone's high quality base oil has penetrating characteristics that help it carry the solvents and dispersants into the valve seats, piston rings and bearing surfaces more effectively and easily than motor oil alone.[align=center]



Rislone Engine Treatment gradually dissolves and removes harmful deposits of varnish, sludge and gum from the internal metal parts without plugging oil passages. These deposits form within engines and can alter tolerances, stick valves and rings, cause noisy valves and lifters, and plug oil screens and oil passages. Regular use of Rislone engine Treatment, with oil and filter changes at the proper intervals, will keep such deposits to a minimum.
Here’s why you can depend on Rislone engine Treatment: When added to the crankcase oil, Rislone Engine Treatment will normally raise and even compression in the cylinders by freeing sticking valves, lifters and rings so that they seal better, thus improving smoothness and power. It reduces friction and wear, especially at start-up time, and maintains normal oil viscosity at engine operating temperatures. Rislone Engine Treatment helps keep engines clean for peak performance. Available in one-quart size and our 15-ounce, add-anytime formula.[/align][align=center]



Restores lost power in the average engine.
In the average engine, there is a gradual decline in power as deposits accumulate and miles and operating time build up. Quality of oil used, frequency of oil change, frequency and quality of tune-up, type of driving and the driver’s operating habits all influence how little or how much power is lost. Rislone Engine Treatment will help restore lost power in the average engine however, it will not add power to a new engine or an engine in perfect condition.[/align]

How Many Mechanics Use SEA FOAM
In Tune-Up of 4 Cycle Gasoline Carbureted or Fuel Injected Engines
Autos, Trucks, and Tractors
[ol]
With engine warm, slowly pour 1/3 to 1/2 pint through carburetor or throttle body throat. (If vehicle is port injected slowly pour SEA FOAM through direct manifold vacuum line that will feed all cylinders, possible sources are P.C.V. valve or brake booster line.) This will pull SEA FOAM down on top of the pistons and to the back of the intake valves to dissolve carbon. Turn ignition off. Restart engine after 5 minutes. If severe carbon build up is apparent, use more Sea Foam as previously directed. Make sure exhaust is well ventilated when using Sea Foam in these various ways as fumes will be extreme for a short time.
Pour 1/3 to 1/2 pint into oil crank case to clean rings, lifters, dirty parts and remove moisture.
Pour 1/3 to 1 full pint into fuel tank to clean injectors, carburetor jets, fuel lines and remove moisture.
Immediate Results: Smoother idle, increased R.P.M.'s better throttle response and improved performance. See label on can for detailed results for use in each area. [/ol]

One pint treats 8-25 gallons of fuel (average 1 ounce per gallon).

In Injector Cleaning Machines

Add a 50/50 blend of fuel and SEA FOAM into injector cleaning machine. Run directly through the fuel rails to clean injectors fast. Add SEA FOAM to your fuel tank to clean injectors as you drive.

 

Ive got a buddy who detailed cars for dealerships in Detroit before joining the Army, he told me about this trick as well. Works on Fords, possible it will work on a Rover.

 

It did a fantastic job! I'd recommend it to anyone.

 

You don't need to mix w/ engine oil, you can fill the crankcase w/ 6 quarts of ATF and run as instructed. IDLE, NO DRIVING. I run it for 10 minutes, shut it off for 5 then run again for 10. Make sure to change the oil filter before and after doing the flush. Also, dropping the oil pan to make sure the pickup tube isn't clogged is a good idea. Someone on this forum recently had knocking and low oil pressure due to a clogged pickup tube.
