Removing the Head

After all of the work so far, my biggest sense of accomplishment came when I removed the cylinder head off the block. This was going to prove to be the most difficult of the pieces to get off so far.  After I removed the valve cover gasket, I began to break loose each of the 12 head bolts on the cylinder head with a hand ratchet. It was very difficult to get each of the bolts off and I bashed my hands and knuckes more than once on the engine once a bolt broke free.  I probably should have worn gloves.
   After the head bolts were removed, I needed to remove the distributor cap and rotor before I could get to the timing chain and finaly remove the head.
   The allan bolts on the distributor rotor started to strip and I was worried that I wouldn't be able to get them out but I finaly got them loose and was able to remove it.
    The bolts will need to be replaced when I put it back together.

The Right Tools

Throughout the project, there have been challenges.  Most of all of the problems I have faced, have had to do with lack of special tools.  I have had a basic set of tools to use, but there have been many other tools I would have liked to have had.  I especially wanted to have an impact drill.  This would be really helpful in removing bolts that are really tight.  These tools have a lot of torque and can assist when a regular drill doesn't work.  Most of these are made to be used with an air compressor, but I want one that is electric so that it is more easily portable.  The best one I was able to find is from Craftsmen.  For auto use, you need a 3/8" size driver not a 1/4" 

When I ran into trouble along the way of dismantling this engine I was lucky enough to be able to  borrow tools from Nate who is my good friend and professional mechanic.  With his tools, what had seemed like an impossible task previously, now was easy.

The best thing I borrowed was a breaker bar, it is a long ratchet that gives you extra leverage and makes easy to remove hard seized bolts.  This was a manual way to remove the bolts that I would have liked to have had the impact drill for.  Breaker bars are readily available at auto supply stores or home hardware stores.  They cost about a quarter to ten percent of what a good electric impact drill does.
This was the breaker bar I used.

Valve Cover and Progress Update

Dismantling the  engine has come along great.  I have the intake manifold off, along with the starter and the thermostat. It is really important that I keep track of each piece or bolt I take off of the engine so that when the time comes to put it back together I can do that.  I am documenting and putting all of the parts and bolts for each part into a plastic bag with notes so that i will be able to put everything back together and know where everything goes.

The next thing I have to do to take apart the engine is to remove the cylinder head. To start I need to remove the valve cover to get to the head bolts. The valve cover is very easy to remove it doesn't take any specialized tools just a ratchet and a socket set. Once the valve cover is removed you can see into the cylinder head and the engine looks very bare and exposed.

The Oil Change

I decided before I do much more work on the engine I should drain the oil. This was something I needed to do and it didn't sound like a hard task, I had changed oil countless times but this time was a little different. The engine wasn't in a car so it wasn't off the ground and to empty the oil of the engine you need to remove the oil drain plug on the underside of the engine and once the plug is removed you need the engine to be off the ground so you can catch the oil in a bucket. This is where it got interesting, I was by myself and had to lift the 500 pound beast off the ground. I used the engine hoist to lift the engine and then i used a milk crate and two 2x4's to support the transmission and keep the engine stable so all the oil would drain. I had to pick up the transmission by myself without the help of the engine hoist and kick the milk crate under.

The first thing I set off to do when I got the engine home and finally out of the car was to separate the transmission and the engine so that I could put the engine on the stand and have a easy place to work on it. That was the first problem I ran into.  It turns out that the bolts used to hold the transmission on to the rest of the engine were an obscure shape called a torx head.  This is a common shape on auto bolts, instead of a regular hex shaped bolt, this is a star shape. 

Because once again, I didn't have the right tools I couldn't remove the transmission.  I wanted to start here so I could get the engine up on the stand, but I decided to get started on the engine instead.  In order to properly rebuild this engine I would have to remove all the parts so until I was able to get the Torx wrenches I thought I would get started.

The first part of the engine I decided to remove was the intake manifold. The intake manifold was held on by 12 bolts on six on the top and six on the bottom. The bolts on top were very easy to remove and were pretty easy to break loose with a ratchet and a 10mm socket. The bottoms were harder to remove because of limited clearance and visibility.  I couldn't use a ratchet and instead I had to use a wrench to loosen all of the bolts. Once the bolts were removed the intake manifold lifted right off.

I carefully labeled all of the bolts and set to the side.

The Engine Arrives

Once I got the engine lift and the engine stand to the garage I was using, I was ready to get the engine out of the truck and into the garage.  However - there was still a problem.  Nothing about this was looking easy.  The problem was, was that there was a two foot gap between the garage door and the back of the truck where the engine was.

     The engine lift I had borrowed wouldn't roll on the gravel with the weight of the engine on it but it also didn't have a long enough arm to reach from the smooth concrete floor of the garage.  I had to figure out how to span the bumpy distance, so I layed a piece of plywood to help bridge the gap between the truck and the garage.  Once I had this temporary solution I was able to get the engine out of the truck and onto the engine lift.  While I was lifting the 500lb engine and gently pulling it back into the garage, one of the wheels of the engine lift came off the plywood and the engine almost fell over. Luckily my friend Robert was able to stabilize it and save it from falling over.  I was then able to lower the engine back on to the ground so we could reposition the lift and make sure we didn't have the same problem again. Once repositioned we got the engine into the garage with no other problems.

 The engine was set on a piece of plywood and cardboard on the floor.  I wouldn't be able to put it up onto the engine stand until I was able to remove the transmission.

Removing the starter and thermostat

After the intake manifold was removed and set off to the side the next thing I needed to remove was the thermostat and the starter. They were very straight forward to remove both coming off with only a few normal 10mm bolts. The starter was in pretty bad shape, it had a chunk of metal missing and was dented.

Both of these pieces went to the side and again the bolts were bagged and carefully labeled.

Setting Up the Garage

Before I brought the engine into its new home, I needed to set up the garage. I was lucky to have found a large garage space that I could use that was close to my house, but it was not outfitted with anything other than some rusty garden tools and a few cobwebs.  I needed proper tools in order to make this possible.

The first things I tracked down to use were an engine lift and an engine stand to make the project easier. The engine lift would allow me to lift the engine out of the truck and get the 500lbs beast off the ground once it was out of the truck.  Once I had it in the garage and the transmission was removed (the first step), the engine was lifted back up and put on the engine stand to make it easier to work on. I borrowed the lift and stand from a friend who owns a local auto shop I actually pushed the engine stand and  lift 5 blocks to my friends garage where I would be working.  I should have brought a bottle of WD40 with me.  The lift made a horrible noise as we pushed it.

If I hadn't had a friend to borrow these tools from I would have had to rent them or buy them.  They are easily available and range in price from $100 - $400.

Riping its Heart Out

The madness began on September 25, 2014, I had found a perfect engine in a wrecked car and we arranged to remove it from the donor car that day. The donor car was a 1994 BMW 535i.  This is a fast engine that is one of the best BMW has made.  With some minor modifications, it can be made to fit into my 318is and will give it even more power than it already has.

To get the engine out of the car, we started by taking off the front grill and removing all of the engine mounts and transmission mounts.   at this point the engine was not completely free it was still connected to the driveshaft but we considered that unimportant becuase we had the power of a tow truck to remove it.
     Now your probably are wondering why we have and why we would use a tow truck to take an engine out of the car... well earlier a crazy ex criminal showed up in his tow truck and said he would take it out so why wouldn't you take up the crazy ex criminal on an offer like that. The engine came out on out second try and actually broke the differential when it came out, we were expecting the driveshaft to break not the differential.
    Once the engine was out it was loaded into our truck and drove it home to Queen Anne where I had found a spot in a friends garage to work on it.
