Here is a Engine afastcar bought off ebay from www-45thparallel-net Ludedude
It really starts here http://pilotodyssey.com/PO/viewtopic.php?t=2832

The Engine was suppose to only had about 20 hrs use on a complete rebuild, looking at the oil and grime covering the outside it looks more like 200 hrs.

Gasket sealer running out all around the base of the cylinder.

I guess the lack of gasket sealer is why it was leaking here.

Its hard to see in the pictures but the end of the crank shaft where the clutch goes on is all buggered up it looks like someone took a sanding disc and tried to sand down the tapered area of the crankshaft.

First thing you see when you remove the side case is METAL everywhere

ALL the teeth are missing from the gear on the crankshaft that drives the balancer.

Looks like someone tried to remove the nut that holds the gear on with a chisel or some other type of CAVEMAN tools, this really has stupid written all over it, I bet if the socket required to remove this nut was "Billet" or made from "Carbon Fiber" the guy trying to remove that nut would own one...

You have to ask yourself when your beating on bearings that hard "is this good for the bearings?"

Busy little moron he was all the arrows are pointing to chisel marks on the nut

doesnt look like he even unstaked the nut? that's a left handed nut also, yes?
I hope he didnt pay top dollar for the motor (( Internal Combustion Engine ? )). What do the cases look like?

Since this Engine was supposedly ported by ATV Racing before removing the head I decided to check the squish clearance since the Engine still turned over and the piston was not seized or all beat up.

I stuck the normal length of .125 diameter solder into the spark plug hole and rolled it over so it could be crushed between the piston and head, it made no contact, so I checked it again in 4 different locations, no contact, I even measured the solder diameter just to make sure yup .125 diameter, nothing else left to do but remove the head gasket, I removed the gasket, the gasket is a Cometic and measures .045 thick, I reinstall the head and run the solder test again this time I feel it crush the solder, I remove the solder and measure the thickness where its crushed and it reads .110 yeah I measure it again then try the crush test again in 4 different locations .110 so the as found squish clearance was .155 or about .100 TOO MUCH Looking close at the head I can see it has been machined before at this point I have to assume they repaired damage to the dome and squish area by removing material but they never removed any material from the gasket surface.

With the head off a first glance at the cylinder I can see it is no where close to being round you can see the wear pattern it is not even close to being round.

Their is a deep wear groove where the ring end gaps are.

Looks like someone beat on the end of the crankshaft for some reason, this was no accident it was hit hard several times.

Next I removed the cylinder, the cylinder nuts were WAY over torqued I suggest the guy that torqued them go buy a new torque wrench!

The gasket is blown out right behind the exhaust this might account for the whole Engine with "20 hrs since a rebuild" being covered with oil, one would think with this much GAS and OIL leaking out the Engine and no doubt spraying on the pipe if the guy driving the Pilot didnt see the oil on the Engine he would smell something when he shut off the Engine.

If the Engine only has 20 hs on it the gasket was leaking since it was first started.

The piston as found, plenty of oil...

Oil removed.

Their is some marks on the rod I am not sure what they are at this point.

It only gets better.

Before splitting the cases I checked the crank run out, on the clutch side the crank shaft is so buggered up where someone touched it up with a power sander or grinder I could not find a place smooth enough to take a accurate reading so I went to the mag side and setup the indicator where the flywheel rides it was .023 run out, you can see the crank wobble by eye!

Chicken before the egg?

Was the crankshaft bent or twisted before it was assembled in the Engine and the wobble is what tore up the gears then the flywheel and stator?

OR

Did something on the flywheel fail then the metal got between the balancer gears and twisted or bent the crankshaft?

The ID of the cylinder bore is 3.226 the largest OD of the piston is 3.216 giving you a whopping .010 piston to cylinder clearance or .005 MORE than wiseco guy recommends, I am not sure who set the piston to cylinder clearance for this Engine all I can tell you is they missed it by a mile!

Well doesn't look good so far........... can it be fixed? good thing I didn't just slap a stator and gears in it and try to run it LOL. I have mixed feelings about Ebay I get allot of good deals on there, when I don't its always a dishonest seller. I realize some people's interpretation of good shape and running are different and its part of buying 20 year old parts. I just hope Hoser can work his magic It's good to have places like this with honest people sharing Ideals and helping out one another.........

I am sorry but it does not get any better, I don't like to add insult to injury but this needs to be said in hopes others in the future don't suffer the same as you....

Over the years myself and others have went to great lengths and took all kinds of flack to warn the general Pilot Odyssey community about this guy...

I see we have failed...

This whole pile I have on my bench really reminds me of the used Pilot CV boots that were sold on Ebay by one of his buddies, I hope others can now see what a POS the mutt really is, IMO ALL those that think the guy is ok or considers him a friend should be PASSING THE HAT and sending you the money so you can recoup some of your losses but I am sure all they will have to offer is more kind words about him and why not they didnt get screwed by him...


Its a shame, pitiful we have someone willing to dump their JUNK on ebay on another brother Pilot Odyssey owner, I am embarrassed to even know the guy, they can play dumb all they want but the pictures don't LIE.

I will do anything I can to help save this mess and to help you turn this around into something positive.

Afastcar, what is the link to the ebay auction for that motor (( Internal Combustion Engine ? ))?
What a mess

Here is a picture of the head, I would say this has been machined at least once the green arrows point to deep damage that was not completely removed, not a big deal it just shows history is all, the blue arrows is some of the machine marks, the red arrow points to the uneven surface, this head can be easily saved I need to really tighten up that squish clearance.

The balancer is toast!

See the missing tooth? Green arrow.

The bearing is bad also.... more on that later.

The red arrows point to the oil pickup hole that carries oil to the balancer bearings, this will be modified or hoser enhanced before I am done.

Usually once you remove the retainers that hold the balancer in place you can just slide the balancer out, this one wont come out so I went to the other side of the cases and removed the bearing holder cover and discovered the bearing is stuck on the end of the shaft so the balancer wont clear the cases.

Look at the end of the shaft someone has been beating on it in the past, is their any part of this Engine they have not used a hammer on? They should change their nickname to "hammer" or "BFH" it seems to be their favorite tool, FYI if you need a hammer to assemble or disassemble a Pilot Engine your doing something WRONG!!!!!!

I counted at least 9 blows with the hammer, think that's hard on the bearings? Maybe that's why both bearings are BAD ...

The bearing on the balancer has been spinning in the cases, see the red arrow above it the bearing is smaller than below it, I will have to measure the case to see if its worn out to much to be reused again.

Its hard to see in the pic but the inner race of the bearing is discolored in one area like it was hot at one time or another, it needs replaced after having all that metal run through it .
