The air thing is done by many people to get more oil out of the valve train and ducts. While it does actually work on many engines (Mini would be included), it also leaves the engine dryer for the startup (although on the Mini you are pouring onto the valve train anyway, and you really end up flooding it with the new oil.

In the end it is probably one of those things that won't hurt, but won't really help. One of those sleeping dogs that I leave alone.

 

I think it is to blow all the sand and crap out along with all the gaskeets and seals. Makes it easier to dismantle the engine for the rebuild. (...a waste of good air IMHO.)

I'm still trying to figure out how one would "Flush the inside of the engine with pressurized air." I can't find the fitting on the engine to do that. It sort of reminds me of the hillbilly advice to mix a handful of sand in the first oil in a newly rebuilt engine to help mate the parts. Don't rev it though...

I like TurboDaves advice.

thanks sir richard, im gonna try that AutoRx engine cleaner on my next oil change.

It is actually customary here for many people to do something like that, to varying degrees. One guy even told me the secret to a long engine life was to fill the crankcase with laundry detergent and water after the first diesel rinse. That way he is able to get 50,000 km out of en engine before a repair.

Diesel is very thin, does not lubricate much, eats seals. Your cheap oil will have about 20% circulating in it. The good oil will then have 20% of 20%  (4% diesel).

If you have enough sludge to dislodge that way, it can get stuck in the passages and clog them. I've seen that a lot.

Oil drains should be done with the oil as hot as possible (without burning yourself). IFF you have a deposit or sludge problem, add a bottle of AutoRx for a it's cleaning and rinse cycles. It will slowly clean it up over a few thousand miles using group V synthetic oil in it's formulation as a solvent. I like to use my version of it ebout every 50,000 miles. Do not use their "maintenance dose".

And never buy cheap oil unless you have too much money. Cheap oil is the most expensive thing you can buy.

 

Birds custard powder, or Ambrosia Devon Custard - I don't really mind what the lying little twat puts on his car and photographs.

Until he does, he has zero cedibility.

really? sir alex is calling me jello and pudding??  awwww so sweet, now i wanna put a  flower in my ear and twinkle my eyes.??

Does custard powder really count:

Bird's Custard Powder is made and served in millions of homes where proper custard is at the heart of a good pud. Add a spoonful to Bird's Custard Powder to pancake mix to give pancakes a delicious creamy custardy flavor. Bird's is the original custard brand, established in 1837 and loved by generations ever since.

I guess so when calling custard...seems sort of like Jello pudding, but that should work in this case.

Oh and Bird's is available at select Walmart stores.

Not sure that applies in this case.. 

Malcolm, although I respect your heritage, I won't be uttering " Long like the King ".

God save the queen, yes.

I believe he is King Numpty.

Custard x 3.

I too, call custard.

If you ever get a better grasp of the enguish language, you might begin to enjoy sarcasm as much as others do. And no, I didn't misspell English. Numpty Or is that Sir Numpty ?

i googled custard and yes it meant eggs and milk together making a nice delicious british pudding.  now maybe he meant bustard and just mis-typed the word. hmm,  but  C and B is separated by V on the keyboard , oh maybe he has huge fingers and typing on his cellphone, lol

im referring to Sir Alex

Alex stop it ! You're making me hungry ! Vanilla? Chocolate? Lemon? Ahh, of wait, you meant.....my appetite has gone off.

Custard.

Poetry !
