It amazes me just how many different ways there are to do the same job. ou: :laugh: I've heard stories of people using many different lubricants while assembling an engine with, "no problems." Examples include, lubriplate, engine oil, moly grease, vaseline, ATF, WD-40, EOS, and STP. I do NOT claim to be any sort of engine building expert. I try my best to do things right to the best of my knowledge. I learned so much from this site. With my current 455 build I dipped the pistons, enough to cover the wrist pin, in engine oil and installed them into the cylinders. I turned the engine by hand many times in the 2 months before I actually started it. I noticed the cylinder walls were very dry just from the rings doing their job as I turned the engine so I used WD-40 to keep them from rusting and to lubricate. Dry assembly bothers me. I'd guess any excess oil drained away long before I started the engine for break in. I wonder how much it matters what you use. Upon start-up, I'm pretty sure, there is oil is spraying all over the cylinder walls below the piston washing away whatever was put there and above the piston there's air/fuel mixture followed by an explosion and flames. I just want my Buick to stay running strong for many years to come. ray: Here's the instructions from my rings...
I will go with the reccomendation Buick says. lube with engine oil. That is what will keep the engine and the rings alive any way.
As long as you are using the bore& hone procedure, as well as the ring material used when your Buick manual was written, that will work fine.
I have a 2 gal can of 30 wt non detergent that I have had for years to wipe down the cylinder walls during assembly. No failures yet. I got the can of oil from my Dad about 30 years ago he was through building engines:beers2: Bob H.
Hi Dave, Reher-Morrison has used WD40 for many years a light dusting of it. I hand rub ATF into the cylinder walls then put a very light coat ATF on rings and a very light coat of 30W on the skirt. Reher-Morrison also mentioned that if the engine is going to sit around for awhile before start up not to use WD40 because it dry's up. Chris
I phoned and asked the boy's at Reher-Morrison today what they use just for kicks. They aren't using WD40 anymore, instead they have gone to light coat of 30w on the cylinder walls and a penetrating spray from Valvoline on the rings. Different strokes for different folks but to me assembly lube would be a big no no. I like my method that I've been using for a very long time, 0-2% leak #'s. Chris
