I've had the head off of my motor for about two months now while sitting in my garage and every other day I spray some wd40 on the cylinder walls to prevent rust from forming.

can any negative effects result from this?


I just want to make sure im not harming the rings or anything in that nature..

you're experience is greatly appreciated!

thanks~

 

it will be ok as long *** you have some kind of oil on the cylinders. I use motor oil and a rag, get the rag oiled and rub it all around the cylinders.

 

sounds good..

should I continue with the wd40 coat every other day or is the oil rag rubdown fine without it?

thanks again

 

oil is a little heaver and clings better.

 

WD40

I use it on the cylinder walls when building an engine, and storing a block. WD40 on the walls, and [oil on the piston skirts when assembling]

for what is worth....

WD40 was developed in San Diego as a chemical to displace water and prevent corrosion. (hence the WD = Water Displacement 40th attempt)

It was even used to prevent rust and corrsion on the Atlas Rockets

check 2000 uses for WD40:

lol

 

i dont think its necessary to spray the walls down every day....once a week should be sufficient as long as its covered and kept in a cool dry place

 

Keep it covered up. it'll attract dirt

 

I got a sleeved block that was not covered until I bought it from a guy. Also, from the looks of it he didn't spray the cylinder walls. Anything I should be worry about? Should I take the pistons out just to inspect them? Plus, there's pieces of dust in there.

 

Just small dust or you talking about dirt particles? if there no rust on the clylinder walls i would put the motor on a stand, turn it upside down, and spray brake cleaner to get any dirt out. Use lint free towel or napkins to wipe down the walls and pistons then once its call clean spray come wd40.

 

wouldn't wipe'n down the cylinder walls do something to the hone marks? But yeah, I'll try using break cleaner....also got some air cans I use to clean the dust out of my computer...might use those too.

 

trans fluid to clean the cylinder walls and keep them fresh

 

well just went outside and checked the block, there is visible rust build up on the cylinder walls...when I bought it, the guy had the block sitting for almost 3yrs w/o doing nothing to it. He had a supra, and wasn't into honda's anymore. Damn, I think I'll have to take it apart and check everything out. I'll post pics tomorrow.

 

IF there rust its better to just take it apart and rehone.

 

here's some pics....






is it okay to use?

 

no it may need new pistons and bore and hone even if it didn't rust its in bad shape and will need at the very least a clean up hone

Time for a teardown and a hone. Maybe a mild bore if the pitting is too deep to be taken care of with the stones.

 

I can't catch any scratches using the fingernail technique. Oh well, its getting tear down.

yeah but take a bore gage to it and see how out of round it is and it also has vertical lines in it. that block needs bored

 

and with boring comes new pistons, so get ready to drop some cream.
