Thread: Oil Pan..please help!

Tweet

NEVER NEVER NEVER sand blast the inside of a oil pan.. never.. if it has any oil baffles in it. still do not like when guys blast a pan with out baffles there still the metal pad in the pan for the oil plug were fine sand can get under and come out .Sand is the last thing you want in a engines .... you get in there with soap and water with a 3 mm red pad or wire wheel on a hand drill till clean . just like cleaning a fry pan blow dry with air a hot tank will clean out a pan and some rust but that has abit to do with what soap was used in it if you do not wash the hot soap off by hot i mean caustic it will what they call.. bloom out ..and make fluzz white stuff on parts not wash good when out of the tank

The part about blasting is that the media raises tiny, almost microscopic cavities for no better word. These little cavities capture and hold the blasting media. This captured media is released once the engine gets hot and the oil will then circulate those nice sharp little chisels, beginning with the oil pump, then directly from there to those nice pretty cam and crank bearings. Once they get done there, then it's on to cam lobes, cylinder walls, rocker pivots......you get the picture now about media blasting oil covered parts

Might even try oven cleaner followed by a hot water and soap wash (I like Tide) along with the 3M pads Pat recommended - just make sure you wear goggles and rubber gloves.

I've seldom seen anything come out of a "hot tank" that did not have residue on it, and had to be scrubbed with a brush or pads and soapy water. All the tank does is take away all of the loose dirt and loosen the crusty stuff so's it can be scrubbed off. After you wash it and have it nice and clean and shiny like new, lightly oil the inside, and the pan rail, and get some paint on the outside pretty quick so it wont flash rust on you.

i have a 250 gallon hot tank i know what they can do with good soap. but your state may not let some stuff to be sold in that state EPA ? well mine with a good soap. i still can buy but could be fazed out any time is a zep soap. vat stripper . will eat rust most all of it .on rust the stronger the soap the more it will eat till it will turn a block blue .mild charge it will make it clean like new metal and like i said its very caustic can only be used on iron or steel . there many soaps out there after getting the wrong soap they said to me . i will love it... Nope . they pump there stuff out. it was very safe it was no more then simple green . vat stripper will bloom more on casting then tin if not wash with clean water and blow dry it will not rust very fast .but when blown clean i crc parts

Mix two parts water with one part molasses, fill the pan and leave it for a few days or a week would be better, rinse out with hot water and blow it dry with compressed air, it will be bran new, and the rust won`t come back before you install, a lot of restorers use this its also green waste safe. ( PS you might have to deal with ants tho)

well just brush the molasses strait on the pan and let all the ants eat it clean they may eat the the old gaskets too
