Hey guys, I have a low mileage L67 that I need to lube and
re-assemble but I have no idea where to start. Does anyone
have some documentation on the process of rebuilding an L67
and what to lube?

Hi Kawana
So you want to build an L67,I've built many motors
From the lawn mower up to Top fule.The first thing
You will need is a Budget$$.There are 3 basic choices
You have in a build,this will all so help set the cost.
----first build is a stock R/R build and most of the parts
Will be at your local auto parts place.most guys can do
This at home in there garage with the basic tools.
      With some beer an help from your buddy's
----the next build will be some performance parts
      More beer an more help from you no who!
Added to it like-cam-valve-upgraded bearings head work done,will
Help the motor breath,an fuel sys,like injectors an Reg,not overboard
But you will notice a bit more power then a stock motor..
----Well the last build will require some expensive precision tools
A shop,time,pick up truck to move your motor around from place to
place,did I mention lots an lots of $ because those shop guys don,t
move real fast,things take forever to get done an cost a fortune$.
I hope this may help you out and others here might post somthing
All so.good luck on your build.

I'm not looking to do any performance upgrades just yet.
I
bought the engine in its torn down state, I just want to
get it put back together in its stock configuration. I've
never assembled an engine before, so its gunna be a
learning experience. Thankfully It's stored at my work,
which is a fabrication shop, so there is no shortage of
tools. I just have no idea where to start, or what I need
to lube, with what kind of lube etc. I want it to be as
fresh as possible, so I'd like to replace all gaskets and
what not.

It's also a very low mileage motor (20,000k) so no
machining should need to be done.

kawana;

This is the engine I sold you?

First thing you want to do is get the engine up on an engine stand so you can turn it over etc. and have it at easy working level. Worthwhile purchase if you don't already have one.

I always check the bearings on all engines I work on to confirm there are no hidden surprises.  This is a low mileage engine but it is always a worthwhile effort to confirm.

Squirt some regular oil on top of the pistons in each cylinder around the piston edge so it soaks down along the piston sides.  let it sit for a couple hours.

Turn the engine over on the stand and squirt some oil the same way up the sleeves and along the piston skirts .  Let sit again for a bit.  This helps with turning the engine over and moving the crank etc. for the rest of the process.

Engine should still be upside down on the stand so pull the bearing caps off the crankshaft.  Careful when pulling the caps off to not scratch the bearings.  Take a good look at the crankshaft and bearings to see if there are any scrapes or discolouration on either.  If all is good, get some plastigauge from a parts store and follow the instructions to place the plastigauge in between the crankshaft and bearing and tighten the bearing caps again.  Take caps off again and measure the plastigauge material.  There will be a gauge on one side of the plastigauge packaging.  Do this for each bearing.

If the bearings are in tolerance, you are clear on bearings. 

I will post again later as I have to go out for a  bit.

Yes Linlor this is the same engine. I'm just about to get
started on the tear down. I still need to pick up a gasket
kit and some new bolts for the heads for starters.

Thanks for the write up, I'll be sure to do that. What are
the torque specs for the bearing caps?

i would suggest a Haynes manual for a car with that motor. there will be a rebuild section there with all the specs. it will get you rolling and most, if not all the info you need will be in there.
