hi guys,
im getting back my freshly machined block early next week that has been acid bathed,bore and honed and decked ready to fit new engine parts.
i have ordered a engine cover bag for the block,but cause i wont be installing crank,pistons,rods for a while i wanted to ask you what can i spread/rub on block on decks and cylinder bores so they dont rust up ??
can i use grease or vasoline may be??
or engine oil or installtion lube may be??
is there a specilised product for this job ??
i guess it would be good if this product doesnt run of the metal easy and is easy enough to clean when time comes to install parts
any ideas please guys??
thanks
shae

Ive used LPS heavy duty Rust Inhibitor. ..I've got a block in my shed for about a year and it still looks good..It's kinda waxy when it dries but comes right off with that orange degreaser stuff(any brand)...You can get it at Napa I think...

WD-40 has worked for me on a block that is over 3 years old. No rust at all.

Cheap solution that works just as well in my trials.

Bad Karma

Same I've used, and we have had blocks sit for well over a year this way with no signs of rust.

Waz-Up Shae...Havent you got that thing built yet What are ya waitin for ..

Spraying light oil on it should be fine. However if its stored near the ocean (sea air) I would apply something a little heavier like cosmoline

jsup

Go to the local marine store and ask for the storage oil.

This stuff is made for the outside of blocks and burns off when the motor is run. It's very sticky.

comp

have brushed on STP

I just use regular old oil and bag it up good.

jsup

Forgot to mention it comes in a aerosol.

I use WD-40 on my blocks. In fact, that's exactly what it was designed for. "Water Displacement" formula 40 was designed specifically to keep moisture off of metal. Always worked well for me, cleans off easily with alcohol for painting later, and I kinda like the smell .

jhammons01

Well WD-40 is a solvent so it would not be my first choice.

Not to mention WD-40 attracts dust and then falls off.

An Engine builder from VW in Wolfsberg years ago showed me what He called "assembly lube" I saw it again from a completely different source when I was tinkering with RX-7s.

Assembly Lube is a 50/50 mixture of Marvels Mystery Oil and STP oil treatment. You get an old style oil can....the one that has a spout and thumb trigger.......and you mix them in there and squirt a healthy amount on surfaces that may rust and especially surfaces that have parts that contact each other.

My .02 for what it is worth

In addition to your oil...

Toss in several of these guys...

wrap it up with this...

And you'll be using the same solution that GM uses when they make and ship engines.

JLeatherman

50/50 mix of Valvoline 10w-30 and STP is what I use for assembly lube. I coat the bearing surfaces, pistons, cam, etc during assembly. For the outside of the block, however, I think it would be pretty difficult to clean off for paint. STP is some pretty sticky stuff...

jhammons01

and further thinking, wouldn't now be the time one would/should be applying engine paint to the external areas of the Block?

Masking any mating surfaces as well as any holes.....then blasting it with a high temp engine paint would be my first choice for preserving the outside areas of the block.
