Lexus/Toyota have a machine that flushes all of the lubrication system. It is fitted to the vehicle by a hose and adaptor placed at the sump plug hole. A second adaptor is placed in place of the oil filter, again with hose. When connected up and running it flushes the system with fluid, then gas, and then oil. It was devised primarily for their hybrid ...

You need to drain the oil (let it drain as completely as possible) and put new oil inane run the engine. If you see it come back as a "chocolate milk" looking mixture, you need to change the oil again. This may take several tries (two or three) to get it all out. You need to change the filter with each attempt as well. The reason this is important is because ...

The Vauxhall Astra gearbox oil does not have a quoted service life. If the oil is drained in to a clean container, and the oil itself has'nt been contaminated then it will be OK to re-use. There are several transmissions on the Astra Range and several have to have their own particular spec of gearbox oil. Vauxhall also recommend changing the trans drain and ...

After changing Diesel oil in an engine it will always look blackish and never a golden colour after only a very! short period of time. This is because the old oil residue left when the oil is changed will always retain a certain amount of contamination and cause the discolouration. You will never remove all of the old oil even if the oil is hot when removed. ...

Have you ever opened up an engine that is using oil, in other words, oil blow-by past the rings. The piston with the oil consumption is clean where as those burning correctly have a layer of carbon on top of the piston. Now that is ordinary engine oil that has removed the carbon. Therefore I fail to see how a very diluted mixture of two stroke oil will ...

The cylinder head on an engine gets very hot. The seals on the cam cover gasket and spark plug tubes can and do deteriorate and leak onto the cylinder head exterior. One other point to watch for is the hoses for the PCV valve. If they have gone 'soggy' or otherwise blocked they will leak oil onto the head. A blocked PCV hose will also cause oil leaks on the ...

There should never be oil on the plug, neither on the "inside part" nor the "outside part". If oil is on the "inside part" of the plug, then the problem is likely a head gasket, valve stem seals, or worn rings. If oil is on the "outside part" then the problem is likely the valve cover gasket, which you mention that you have replaced. Oil under the valve ...

If you are suggesting there was oil inside the head where the valves/cam(s) are located, this would be perfectly normal. If you are saying the oil puddles are outside of the valve/cam area, this isn't normal, but should be taken care of by you putting a new valve cover gasket on the engine. I would say, clean up the entire work area, complete the replacement ...

To add a little bit to Paulster2's answer the upper and lower Explosive Limits of Gasoline is 7.6% and 1.4% respectively. This means that a concentration outside of those limits will either be to rich or lean to burn. And since Gasoline's Flash point is -45 °F (-43 °C) it's pretty much always putting off vapors, which would push any air out of the tank. It's ...

I pulled this from the talk side of Wikipedia page on electric fuel pumps, which I think explains it pretty well: I am an auto mechanic who also has a chemistry background. The reason electric, tank- mounted fuel pumps do not cause explosions is that the concentration of fuel vapors is too high to allow an explosive mixture. The volatile (which in this ...

If you checked your oil level and discovered it was low, then topped it off correctly, you'll have caused your engine absolutely no damage. It does seem as though you have other issues with the oil leakage. You'll need to take this to a shop to get the oil leak itself sorted out. Depending on the amount of oil being lost through the leak, you can drive it ...

It shouldn't have caused any damage, as long as there is still plenty of oil left in the engine. To remove it you will need to use some kind of degreaser - you can buy proper engine degreaser at many automotive suppliers. It is probably worth getting the engine bay properly steam cleaned however, as you'll never be able to get into all the little holes and ...

You may have over-filled the oil reservoir, which is dangerous but not necessarily guaranteed to cause problems. As long as the excess oil has somewhere to go, in your case leaking out somewhere, You can still drive it to a workshop and have them take a look. Just drive carefully and don't let the revs go too high, i.e. stay under 3000RPM as much as possible ...

Think I might be stupid. Should have checked around more. Checked around online, as I had before, but this time found a yahoo answer I had not seen before. "'98-'03 ML320 which would make it a gasoline engine and it uses 8 L or 8.5 quarts. ". Looks like I far underestimated how much oil this beast uses. Guess I'll oil it up some more and hope for the best.
