Engine Oil flushing concentrate

I have used several types, when I had an older 3.2 lt Jackaroo with a sticky tappet, can't say it was ever sucessful though

I have also read somewhere that with the modern engines it should not need a flush put through them

But I think if your confortable with it why not.

There is a house in New Orleans they call the rising sun ,, oops wrong question ,, thing is this forum has a magic search function ,and believe it or not you will find your answer about flushing engines only runs to 4784 answers , no bleedin wonder u are confused if u still cant use it .

Good quality flushing agents are effective in specific circumstances, they should not be used on a whime. What they do is dissolve baked on carbon, sometimes, said carbon is helping an old motor maintain compression or sealing up a worn valve guide. On the other hand, sometimes it is causing a valve to stick or stopping an oil ring from doing it's job.

On a modern motor (tight tolerences) it is almost a waste of time, far more effective to use good oil and change it regularly.

Bang this as much as you feel, but a few years ago had to replace broken valve stem seals on my '76 diesel L/R.
Compressed the valve springs (piston at tdc) replaced the seals but the sludge accumulated on the head was horrendous.
So with a bit of lateral thinking, and reckoning I could't damage the old girl that much I got a tin of the degreasing spray stuff ($2) from Crazies.
Mixed the can full with about 1/2l. of oil and whacked it in the engine. Went for about 50k. run, came home, drained the oil and B/hell it came out like bitumen.
Filled with new oil and couple of weeks later took the rocker cover off to check the valves.
There was not a skerrick of sludge left where it had been thick, in fact clean as the rocker area of my Disco.
Since then the oil has been cleaner for a longer period, and no adverse effects.
I have to think that the CEM stuff is only a strong solvent, but at a price.
Anyone following this advice is I can have no responsibility for any problems pertaining. It worked on my old L/R, that is all I can say.
