Engine Replacement

[CLS447]

I try to get as much time on this project as I can right now.

I am replacing the Souza engine that had the compression problem with a bottom end assembled by RAM PERFORMANCE.

The new "bottom end" has the extra case pins,extra oiling, RAM's cam,& the forged pistons.

Everything else gets moved over to this new block....oil pump,water pump,RAM heads,intake & carb.

Break her in & try again !

A few snags....I have to tap the crank bolt holes to refit the redrive.

9mm x 1 to 3/8 x 24 .

Lots of other little details to do also like powder coating the oil pan and new bellhousing & all the other parts that had not yet been finished.

Looks like another busy winter ! Here are some pics...

Chris: I am sure it will be as sweet running as the rest of the machine looks.

Keep the rebuild pics coming.

Chris. Call me this weekend. I would like to see a powder coat demo.

[Harry_S.]

Nice clean shop you have there, Chris.

Is it brand new,or, don't you do your work in there?! :D :boink: :wacko:

Just jealous.


Cheers :)

Howdy Chris,

Just put the *#$@^% engine together and go fly. Tell Char I said "Hey":D

[CLS447]

Harry, don't be fooled by those pics. I will step back a little on the next shots.

Paul, Shar says HI ! We are trying to get it back together & remember this is not an enclosed machine. IT IS COLD OUT !

[CLS447]

Tim, we would sure love to see that !

Here are some pics.

1. the new powder coat shop

2. bellhousing being baked

3. sloppy shop

4. new engine with bellhousing on

The crank has been retapped to 3/8-24 and flywheel reinstalled.

The water pump & oil pump have been reinstalled.

Motor mount rails have been lightened up and polished.

The water return port on top of the block has been opened and tapped 1/8 inch pipe.

The oil pan has been powder coated and ready for reinstallation.

We will now reinstall the block to the gyro and then bolt up the heads and intake.

More pics to follow....

Beautiful engine Chris

We await your pics.

[CLS447]

Thanks Thom !

We just got our N# cards & looks like we might get a visit from this country's best DAR in the near future !

We took our EAA data plates for engraving yesterday.

Now I need to get the repairman's certificate course done.

We hope to do that at Mentone, if they get one together.

These are the first pics that we downsized & posted. We did them with them with the free Picaso program......Thanks Udi !

Hey Chris, the engine looks great! How soon before test runs? Your doing a great job and I can't wait to see you again.

I thought Tom Milton was doing your inspection?:D LOL Just kidding, I couldn't resist.

Chris, the new engine looks great, nice work! Those pistons look like coffee cans - you should get some good power now. Let me know if you find out any more about the repairmans course. Mark

[CLS447]

Thanks guys ! I will keep this thread going as we progress.

Screw, I can't wait to run her up again ! This weekend should prove to be very progressive, I hope !

Once the motor hits those mounts, things will move quickly. Basic reassembly.

Wish us luck!

Looking great!

[CLS447]

Tim, I will have some pictures concerning your nosewheel very soon.... so hang in there !

[dragonflyerthom]

I like that redrive .

i Want A Ride!!!!!

Lookin great, makes me want to go to work on mine. I'm getting a very slight oil leak from my pan after 75hrs. and used standard silicone sealant, what did you use?

Lookin great, makes me want to go to work on mine. I'm getting a very slight oil leak from my pan after 75hrs. and used standard silicone sealant, what did you use?

My EJ-22 gave me some oil leaks from the pan until I cleaned it off very good, checked the flatness of the pan on a known flat surface then used Yamabond to seal it.

When you put the Yamabond on DONT torque down the screw/bolts. Just barely seat them. Then after 48 hours give them an extra 1/4 turn.


The pan has to match up with the engine exactly. You might consider (after cleaning it ) using some dye or ink on the engine placing the pan on then removing it (no sealer) and seeing if there are any points not making contact as shown by no stain on the pan.

That was the only way I could get mine to stop leaking.

If the leak is very slight I would try degreasing it, dry then run a bead of Yamabond around the outside lip of the pan.

Parke & Tim, Ron at RAM performance told me to use "the right stuff" from Permatex.

You can see the can in the one pic. The 7.5 oz can was close to $20 at Pep Boys.

I had a leak before with the cork gasket , so I redid it & it still leaked. He told me to make sure that I got it on the bolt threads also because that is where they tend to leak.

I got my fingers crossed ! I hate oil leaks !

[StanFoster]

Chris: Cant wait to see that motor pushing you throught the air.

Looking good.

Stan

[CLS447]

Stan...., it needs to push Shar & me through the air !

I'm praying !

I still want to try longer blades to see if that helps with the power. Just gotta be sure they spin fast enough.

Also I want to give an IVO a spin !

Everyone keep their eyes open for a nice low mileage EJ25 SOHC with ECU & harness at a good price, just in case !

[Parke Hoover]

Tim & Chris thanks for the info.

[LARRYEBOYER]

Chris! You did all you can do now the new Subie has its job to do and I think you will be happy!!!And you and Shar will look good doing it!!!Don't forget the second annual Rotor and homebuild Aerofest at Mifflin County airport the second week of August 2007.If it defies gravity, it is welcome. Park, Steve, Chris? Ben, Paul Barrett,and me plus ++++++Lots of homebuilts. camping at the airport and the overflow on my 14 acres near the airport. Who is comming??

[CLS447]

Sounds good to us, Larry !

The more the merrier !

[LARRYEBOYER]

Chris. I want this to become the event you don't ever want to miss in the north east. Benson Days, Mentone, Rotors over Carolina, and The NorthEast Aerofest at Mifflin County!!!The first 3 you fly over flat ground. The last is flight over and between the Appalation Mountains.Beauty beyond description.
