A pretty good video. Thank you for posting it! It sure would help the forum if more people shared like this. :thumbsup:
Going to the large time and financial expense of an engine rebuild, it might be better to replace the pistons with the new, updated Toyota pistons that address the problem they had with the first design, instead of reusing the old pistons. The part number for the redesigned pistons is Toyota part # 13101-22142. If rebuilding one of these engines, verify that art number is correct at your local Toyota dealerships Parts Department. Installing all new bearings is also a very good preventative maintenance measure, as is installing a new water pump. Engine rebuilds cost a lot of money and for a professional automotive technician to perform the work, the price we can expect to pay is over well over $2,000. It's a very labor intensive job.
I was very surprised that the gentleman in the video didn't use protective gloves on his hands before handling engine parts coated with used motor oil. Aside from sulfuric acid in an automotive battery, used motor oil is the most toxic fluid in an auto center and is loaded with carcinogens, (cancer causing). Working with heavy engine parts, I was also surprised to see open-toe sandals being worn. That's just asking for a broken toe or foot from an engine part or tool, etc., falling onto their foot.
I am very surprised the gentleman in the video didn't use an engine assembly lube when rebuilding the engine. Tearing an engine down and rebuilding it, all the motor oil is removed from metal-to-metal wear surfaces and there is no film of lubrication between those parts anymore. Also, the engine oiling system has no pressure in it, as all the motor oil has been removed from the many passages inside the engine. So after the rebuild when starting the engine for the first time there will be very accelerated wear, as all the bearing surfaces inside the engine, i.e. the crankshaft bearings and the crankshaft, the camshaft bearings and the camshaft, etc., have virtually zero lubrication and damaging metal-to-metal wear will occur. This is a completely dry start and is very bad for an engine. For this reason, when rebuilding an engine, an engine assembly lube, (and not just motor oil), should always be used. An engine assembly lube has special anti-wear additives to prevent that damaging metal-to-metal wear.

Here is a video on YoUTube.com by Peter Finn regarding the 1998-2002 Toyota Corolla engines and the typical oil consumption problem they have. English is clearly his second language, so you have to listen carefully sometimes to understand what he is saying, but his videos are very good. Note that Peter is wearing protective rubber gloves on his hands to avoid getting cancer from used motor oil.
In this video, Peter shows us what happens with the piston rings becoming sludged up and stuck, preventing the piston rings from moving because of using comparatively lower performing conventional petroleum oils and are no longer able to provide a proper seal between the rings and the cylinder wall. This allows oil to get passed the piston rings up into the combustion chamber where it is then burned and sent out into the exhaust. Using a high quality synthetic oil like AMSOIL can help to alleviate this problem these engines have as AMSOIL synthetic motor oils are very resistant to the high temperatures found in the piston and ring area, preventing the formation of sludge, allowing the piston rings to stay sludge-free and able to move and provide a proper seal, not allowing oil up into the combustion chambers to be burned and sent out into the exhaust.
The oil consumption problem that arises with these engines is because the temperatures of the piston and ring area are too high for conventional petroleum oils to withstand because of only two oil holes per side in the pistons, which consequently doesn't allow enough oil to that area to cool it, allowing temperatures to increase too much for the petroleum oil, breaking the oil down, causing sludge, varnish and gum to form, which then causes the piston rings to stick. It is interesting to note that since then, all Toyota's now come with synthetic oil installed in the engines right from the factory assembly lines and Toyota recommends all subsequent oil changes be completed with a synthetic oil. Consequently, the engine oil problems Toyota was having have greatly decreased.
