Cooking oil on engine parts

[maldotcom2]

Is it ok to use canola oil to protect engine parts pre-assembly? Will the cooking oil react badly with engine oil? I ask because i want to use aerosole canola due to ease of use.

Yes it will.

Oils aint oils.

Use a pre assembly lube. The LAST thing you want to do is introduce contaminants that will break down under adverse conditions, into a system that has it's highest frictional wear.

Ideally you dont even use assembly lube, you soak in the oil your going to run it with.

There are no shortcuts in preperation for a rebuild.

Yea not to mention cooking oil will run off all the parts before assembly anyway, use a decent lube/grease to protect.

I see. Well what if i diluted some engine oil with petrol or something and then spray it? Or is it definitely a brush job?

Or you could just use proper lube/grease. I think you will find petrol may eat it away.

I dont think assembly grease would be suitable, i'm after something to do the entire heads, not just the machined surfaces. I probably will use assembly grease on the internals though. I guess i'll just brush them with engine oil. Cheers guys.

Give them a spray with WD40.

Depends what your cooking really...

[maldotcom2]

WD 40 really? Damn i just spent 2 hours with a brush. Ahwell good to know for future reference.

although past the time of need...

why not a lanolin based spray it will coat for years but will be disolved by oil & petrol later.. Fo assebly I would use Nulon assembly lube but for heads combution chambers, galleries etc something lke lanox.

cheers

DON"T use WD40.
DON'T use Lanolin.
DON'T dilute oil with petrol.

WD40 WIll burn and carbonise heavily at very low temperatures - read 300 degrees - Way below combustion temps. This means that you will add by products and carbon deposits to a CLEAN NEW OIL in a TIGHT un broken in Engine. The carbon will sit on the piston rings and could mark the bores, or contribute to an uneven breaking in process. In addition, the crap that WD40 breaks down into - may cause your oil to break down as well - in your nice tight new engine, causing it to wear rapidly or unexpectedly.

Lanolin is a good protectant, but again breaks down at much lower temperatures than oils, and breaks down into compounds you don't want contaminating your oil.

Diluting oil with petrol will directly cause the oil to break down. This broken oil will contaminate your un broken oil.

Think of it like this. Your making a cake. You have to grease the cake tin to bake it. Do you greas it with olive oil ? Engine Oil ? Canola Oil ? Lanolin ? or the butter that is already used in the recipe.

They all will work, but only butter will leave it tasting as it did before, aome will leave the food unfit to eat, and some will make it taste funny...

Use the butter - Engine oil.

Actually i always used olive oil for my cake trays. I get your point though. Cheers.

Definitely dont use WD40!!!

use molybond... its comes in a pressure pack can, its a dry lube... ideal for running in parts
