Re: Engine seized 2 miles after rebuild
I had he same problem as couple of the other guys mentioned. The starter jammed into the flywheel and locked the motor up. I thought the same thing as you, the motor had seized. Just unbolted the starter and pulled it out a little and it released. For some reason I don't know why it happen a couple of times and then stoped.
Does anyone out there know why this hppens? |

Re: Engine seized 2 miles after rebuild
Sounds like ring gap, or lack of.

Re: Engine seized 2 miles after rebuild
I now know why I don't run a filter in May.

Re: Engine seized 2 miles after rebuild
Let me take a guess too.
Try and turn the engine backwards. If it's a standard shift, put it in 2nd and push the car backwards. Maybe with a little luck, you have a nut, or something that was dropped into the engine while assembling. Let us know what you find. best of luck |

Re: Engine seized 2 miles after rebuild
Check the date, guys, this problem was diagnosed and fixed over a year ago!
Ran without a filter after the plug fitted for 95% filtration. Mart. |

Good luck finding out what it is, and let us know what you find as you disassemble. Bob |

Re: Engine seized 2 miles after rebuild
This is the biggest fear we builders have. We try to check everything but every once in a while you miss something. The 294 won't be run until late February, and I wonder if I forgot anything. Last year a carb screw came loose and broke a piston in a test engine. Instant bang, but we keep going. Hope it's something simple, take care.

Re: Engine seized 2 miles after rebuild
I stopped using silicone caulking on my gaskets on my Harley motors years ago just for that reason... It clogged a oil port ...good by stroker motor......

Re: Engine seized 2 miles after rebuild
EVERYONE, look at the date of the posts. This is an old June 2011 thread. Start at the beginning and you'll get the whole story.

Re: Engine seized 2 miles after rebuild
I remember this post well but don't recall a final report from Merc Cruzer saying that he got this engine repaired and back on the road.

Re: Engine seized 2 miles after rebuild
JM35 Sedan:
As it turns out, I had drilled the passage to put in a full flow oil filter system and then forgot to put a plug in it since I did not use the system. Failed to put that on my check list during assembly. Bottom line I was not getting oil to the rod bearings. When the symptoms started I did shut the motor off and towed the car home (two blocks) and then pulled the pan. That resulted in pulling the engine out again and tearing it down again. The bottom line is the bearings did exactly what they were supposed to do, (not my first engine but it was my first flathead) only damage was to the bearings. I had the crank polished and re-cleaned the block. New set of bearings and I was good to go. It has been great and has all the power it should after a full rebuild...oil pressure 60 lbs. If this post is still helping after over a year then it was well worth the learning experience for me. The bottom two pictures were taken with the engine still in the car. To my 53' Merc, I say...thanks for the education (which will never end), all in all the tuition was very reasonable....and my love of driving it will only end when I do. Originally Posted by Carbroke How can you bore it .60 over and reuse the original pistons? Supposed to buy over-sized pistons to match. Not sure why it siezed, because you haven't said what actually siezed yet. But I know you need to put bigger pistons back in. In my case I used a new block and had it bored to match the 60 over pistons from the old block. Last edited by Merc Cruzer; 01-05-2013 at 11:25 AM. |

Re: Engine seized 2 miles after rebuild
I second that. Put it in second or third gear and rock the car.

Re: Engine seized 2 miles after rebuild
Merc Cruzer, thanks for the followup. I'm glad to hear that all ended well and you are enjoying the ride. Reading your original post may have prevented me from doing the same thing with a freshly built 59 series 284 cid engine. I did the 95% FF system and was planning to plug off those rear ports for initial start up.

Re: Engine seized 2 miles after rebuild
While I understand almost all that has been said in this thread except the part about the plug or connection that has a 1/16 hole drilled in it, where does this plug or connection go? Thanks Jim

Re: Engine seized 2 miles after rebuild
This has been a very good thread.
I will add a half a picture of the fitting used by the Canadians that acted to block the other way while it was being used, and allow normal flow internally through the block when no external fittings (cooler, filter etc) was not connected. This is the one Barlea referred to. I will show also a picture of the circuit diagram showing a cooler, a bypass valve, and a filter, from a Canadian Ford (Bren)Carrier. One confusing aspect of this thread is about the two types of filtering systems used on these fords. The original canister type is a bypass system that bleeds off about 5 to 10 percent of the oil, to filter it, and return it directly to the sump. These filter elements were a very fine filtering media that removed very fine particles. They had a large surface area, and the oil supply to then was limited by the restrictor. They could stay in service for a long time. The rest of the oil being used to lube the engine before its return to the sump. The full flow systems (95 or 100 percent.-two variations) used a modern type filter where all the pumped oil is sent through the filter, then goes on to lube the engine before returning to the pump. The variation between the two full flow systems is this. In the 95% system the oil going to the rear main is not filtered before it goes there. In the 100% system it is. The 100% system requires much modification. The 95% system requires very little, and what you need to keep in mind is that it(the oil) is already pretty clean as there is a 95% chance it went through the filter before it was picked up by the pump, this time around. |

Re: Engine seized 2 miles after rebuild
The Ford Canada full-flow system was tested in quite a few locations including the North African desert, Sicily, Italy, France, Holland and Germany for about five years in the 40s before it was offered as an option on civilian cars and trucks until '51. Some of the testing was probably under even more severe conditions than us codgers can dish out to the flathead. Never heard of a problem caused by the filtration system so it could very well be worth it. ..B.
