1917 Buick D45 Engine need of help.


Recommended Posts

Hi there all.,

Haven't even finish my 24 touring car...and this came to me from a friend of a friend ..

After many years in the garage, now it's my time to tinker with this project,

Looks like they want it to build a stroker engine and fit it with new technology bearings and crankshaft but was never finish.

There's a new crank been build from scratch..and i can see today after getting the second load of parts that in one of the crank case they were making big modifications to accommodate new modern bearings.

Will post those later ..

But i just going to get things going fast on this ..will need some help to get gaskets to put the engine together and also a new set of pistons and rings for what looks to be a 16 to 1920? Engine blocks that some are clean and cut to 3 3/8+.60 over to 3.453 final . That's one block ..and some others are hone and looks to be smaller diameter.

I haven't gone through any parts yet ..but i know i don't have those parts ..

I do have 3 set of pistones with rods and all ..so I will check on those first.

This car build was started by a guy name Stanley Jones from simi valley CA. And then was sold to the next owner in 98 and was garage till now.

Hi Morgan..

It looks to be a dual voltage car .. its a 6v and 12 volts.

it has a few modern relays and new wiring done.

let's see if anybody can identified another mod they did to this car from studding the pictures..?

What a menagerie of parts!  I see at least three crankcases (cannot see enough to tell what years) and five cylinder blocks.  Three of the blocks are 1918 and up.  The parts alone are worth more than the car.  I simply cannot even begin to imagine trying to put that car together using what is in the photos.  It would take at least two experienced Buick persons a few days to go through everything and get things sorted out so that it could be determined just what is there.  I get tired just looking at that mess.

Hi there. Back from a full day of sorting parts out just for the engine part of it ..

All the blocks are super clean inside and most of them are hone. 6 of them

One it's  .60 oversized.

One crankcase was modified to fit the modern crank witch it's not finish. the crank size  looks to be Chevy 2 inch bearings.

one other crankshaft was drilled for lubrication.. very well done job.!

Rods they are two size..

A large babit diameter and a small one..the small ones fit a standard small size crankshaft..

What a job ..and now we have to see if we can fit a 24 crank in to the highly modified crankcase and grind it to fit.

At least I think I can put two engines together for sure..maybe three.. will keep working on it next week.

Anybody can help me on identify the year of each engine numbers.?

Thanks..!

Cheers.

Apolo.

One more technical question..

I can see two types of oil pans..

One withe oil tube that runs on one side ( inside) with a line coming out on the center of pan.

On other all closed with no holes or line inside.

Second question.

It's the tolerance for the cast pistons bigger than the aluminum ones .?

Trying to figure out if the pistons i have are usable for one block at least.

I would say aluminium pistons need more clearance in (cast iron) cylinder bore than cast iron ones.  Cast iron pistons expand with (theoretically) the same rate with cast iron block, while aluminium pistons expand lot more thus require more clearance...

Today's job was to find a way to use an oil pump to this crankcase..

Lot of work when into this one..!

there's any way to know by the casting numbers the year of crankshaft.?

and there's anybody try to put an  high volume oil pump  on one of this engines.?IMG20230313185211.jpg.6f370100b7f9e0a1ea8ed264d54d405f.jpgIMG20230313185229.jpg.fd4081a1ae500922a86676ed10a8758b.jpgIMG20230313183129.jpg.e3267b395fcff511af34e33b4fbbc445.jpgIMG20230313183129.jpg.e3267b395fcff511af34e33b4fbbc445.jpgIMG20230313183341.jpg.4f410546aed594aa9cbc796d39ba890b.jpgIMG20230313183349.jpg.3b4347e32704737716b469b0d294b22c.jpg

On the D-Series engines and later models also, the oil pumps were driven from the back end of the camshaft.  Why would anyone want to dinker around with the oil pump on one of these engines?  Things worked rather well the way Mr. Marr designed them - why go messing with it now.

If it were mine, I would keep it simple. 

 

I would use the original crankshaft, remove the three of the four main bearing caps that are not original and replace them with the original caps. Get the crankshaft cleaned up and have the bearings rebabbited.  Dig out the original oil pump and install it as original.

 

There is no reason to try to re-engineer these engines.  They went hundreds of thousands of miles on the original design worry free.

 

If you go back to all original and you need a part, it is easier to find an original than try to find a part for a franken-car with what ever the dimensions. 

 

Just my opinion and what I practice. 

 

The one thing that I do change on my vehicles that is not original is to install aluminum pistons instead of the original cast iron pistons.  Less reciprocating mass which should have less stress and wear on the bearings.

I think you have two types of engine here; "smaller" one that is "D" of 1917 and "bigger" that is likely "E" for 1918 as determined above by engine #. I would think the later is overall longer due to bigger bore, so crankcase, crankshaft and block are longer and simply does not interchange with the earlier type and (I guess) also do not fit into earlier chassis.

 

The 1917 D block also has water pump entry between #3 and #4 cylinder, while later has the entry between #2 an #3 cylinder. Also I believe that 1917 block has all 12 valve nests the same size and in line arrangement, while the later has one set of valves bigger (not sure if this inlet or exhaust from top of my head) and "zig-zag" arrangement due to this size difference. 

 

And yes, I would also go as much original as possible as Larry suggests, you have great selection of parts to start with, so why to re-invent the wheel 🙂

Thanks pepcak..

I do know i have 2 different types of engines here .

Now you made a good comment about water inlet witch i did not notice that ..thanks..

Yes I know guys .. I'll try to keep it as much as original as posible ..BUT. I don't know what this previous owners where trying to do here ..and that's what I like to find out..

This pictures I'm sharing it's just to show what I'm going through here ..it doesn't mean I'm gonna use this ..but since I have enough parts to make 3 engines..i like to finish also what they started here. 

I'm a guy that it's fascinated by all this mechanical convertions people do on this old cars.. specially at the level this Stanley Jones guy did it..

That crankcase you see with bearing cups made new ..has a line bore done to fit the new crank shaft they where making .

So that crankcase it Destin to be finish that way.

Now the 1918 crankcase will be the one that i will do as stock for the car.

BUT...i only have the large crank to fit on that one (large crank) And it's drill to suit a high volume oil pump .. so since I don't have any other large crank i want it to do that ..

But we where thinking that in order to pressurize the crankshaft i will have to plug all the holes in the rods...and then again i don't know how we can do that without damaging the babit.

So looks like the cheapest, fastest solution will be to use the crank as is and that's all. 

UNLESS...i can use the set up it's on the car and be done with it.

I have to clean all the engine parts first and then i will get an accurate readings of rads . mains and crankshafts..

I dunno. It would be fun to see what a Buick motor would be like with a couterbalanced crank and aluminum pistons. 😁 Nicely balanced it should be a performer. Of course, I'm spending your money. If the rods are machined out for shells the hole wouldn't matter.

If you have the money, there is nothing wrong with a properly done counterbalanced crank - even with the original splash oiling.

The counterbalance will make evrything easier on the engine.

A well done pressure oiling system would be a challenge but can be done. I have seen it done on an early Thomas Flyer.

Obviously, leaving original is fine and cheaper.  You get to choose, just like everything else.
