Ford 8N Sleeve installation

OK, I know that somebody out there knows the answer to this cause I know I am not the only one who has ever replaced the sleeves in an 8N.
This engine had the .090 sleeves and the were worn beyond 20 thousands, so I pulled them.
Built a sleeve puller from some scrap I had laying around and pulled the sleeves from my 8N. Sleeves were real tight and took a while to get them all out. After each one I saw that the cylinder was wet with oil, maybe, and smelled like burnt oil.
I wonder if whoever installed them the last time coated them with oil before installing them??
My question is,
1) should I use and oil on the liners before installing?
AND
2) is it necessary to use Loctite on the sleeves, even if they are a real tight fit?
Thanks to all for any advice.

No need for adhesive if the sleeves have adequate (.0005/.0015) interference. As with most press fits you can oil the sleeves to facilitate assembly.

Ok, good. I will try some oil as the sleeves are tight and I don't know the clearance yet but my neighbor, a machinist will measure for me now that I know what to look for.
Thanks again.
 
I've never tried it on sleeves but I had to install a press on interference fit bearing a couple months back. I bought 5 lbs of dry ice at my local
welding supply store and covered the shaft with it for bout 10 minutes. The bearing fell on it right in place.

Or alternatively use a bearing heater. If the wife don't catch you a poor man's version that works great for open bearings is the french fryer :roll:

I guess you haven't taken many engines apart, all sorts of strange smells get released when you take things apart, even as simple as pulling the main bearing caps releases smells of hot oil and combustion products that have sneaked down deep into the workings of the engine. NOTHING to worry about.
