Heres the deal....I put this motor together and it broke. Yes, It sucks and I'm not happy about it, but don't judge me. I gave it a shot and it failed. I plan on taking it apart and learning from my mistakes, if it was due to my mistake.....and of course this website is about helping people, so hopefully someone else can learn from this as well.

But lets have some fun with it. I will give you the basic facts that I know, but you have to guess what the cause was....and what the damage is inside.

Here is what happened:

I launched the boat, drove up river and back down at about 3k. Upon turning to go back up river I rolled into the throttle and got about 3/4 throttle and it made a ton of noise. I immediately pulled the kill switch. Upon immediate inspection, the bilge was full of oil. (14 quarts of royal purple )

Stuff I can see wrong so far:

• The oil pan has a bullet hole it the front center of the pan
• I found the oil pump shaft up in front of my feet near the front bulkhead. The end of it bent in a near 90 degree angle.
• The pan has a dent on the right side near #5
• #5 doesnt pump air at all out of the spark plug hole - didnt bother checking any other cylinders.

So what do you guys think happened? Winner gets a whopping bag of nothing. I broke a motor, why should you profit from it?  I will be pulling the motor apart tomorrow (Tuesday) and will be posting info/pics as I pull it apart.

Here some pics.....

Hole in the front of the pan where the oil pump shaft shot out

Dent in oil pan near #5


Remember, we're just trying to have fun here. 

We're the rod bolts tight?  #5 might of came loose and slapped the rod around.  And broke it sending it all over the bottom.  I've see that same thing happen and that's what we found what happen.  It's just a guess but won't know for sure until you drop the pan.

The motor was built to spec with correct tolerances and torque specs.

The above statement doesn't mean I'm saying a professional motor builder, just stating I did it according to what was expected.


One last fact I forgot to add....

The motor still turns over via starter and doesnt make any noise.

Brad no matter what happened u did a great job on the motor looks great and sounds badass we learn from our misshaps even know it cost u an oil pan I'm positive u will over come and just be glad it didn't go through the boat. P.s. very cool weekend had a blast. Thanks

I hope you drained that oil and bilge water into a bucket and sucked at least 12 quarts off the top, run it through a coffee filter, and save it for the next
Motor.  It's still good.  I used to strain chunks of piston out of my perfectly good barely used redline race oil in my old race car.

Does your pickup have a non-screened hole in the middle of it like some?  I didn't see any twist in the shaft when I saw it on Sat. Night, indicating that it probably fell out somehow and got hung up with the #5 rod to make that nice little 90 degree bend, rather than something having locked up the pump...or maybe both...the pump
Locked up, arp shaft is stronger than Chinese melling pump, pump broke and #5 bent, broke itself, and fired the shaft at your foot as a reminder to build a Chevy next time or buy an outboard.

I'm not sure how fords are assembled, but I bet you'll find the oil pump (or at least parts of it) sitting at the bottom of the pan, or at least the drive receptical broken.

JACK

just saw a ford oil pump do that too-snapped between pump and bolt flange

well, not sure what failed first and took out the other between the oil pump and the #5 rod....but its a mess.

broken rod
broken piston
broken rod bolt
broken oil pump
broken oil pump pickup
smashed up oil pan - again.
both valves on #5 slightly bent

block looks ok
crank is going to need to be turned

So new piston/rod, rebalance, new oil pump, pickup, repair pan (again), have the heads reworked....and I'll be good to go.

If I had the parts and resources and unlimited amount of cash.....i could make Idaho.....ya right, fukk racing. 

There's your problem, your oil pump and distributor are on the wrong side of the block

Damn, that is a helluva mess. Still no clues as to what started everything?

Well at least it happened in Parker instead of driving all the way to Burley to break it. Sucks regardless....

....the oldest joke of all time at the worst time possible.  dont be a jackass.

Gotta have a sense of man, that pans still sitting in my garage if ya need it
