Engine seized 2 miles after rebuild

So he mis-spoke about .60 and .060, he had it done right. Get off the nitpicking and try to help.

If it stopped that fast I would look 3 places before I got too excited.

Pull the radiator cap, is the water way down? Might have a bad gasket or a crack that is putting water in the cylinders and locking it up. Plugs is a good place to check too like others suggested.

Check the starter. It may be bound up.

Pull the distributor. Check the gear. You might have something broke in the timing gears.

Good luck,

Drain oil first Look for chips ,Also make sure it wasnt the trans that went,Seems fishy after 2 miles,I usually get 750 to 1000 then They blow up.I ve only had one ,,,It was a 76 sbc ,Cam snapped in half,Unless you over revved it ,It seems fishy .....As other guys have said pull plugs and disconnect trans........And drain oil look for coolant....And or metal chips .

 

WOW.
First things first. If the engine is siezed, take it out of the car and pull the thing apart. Something is clearly wrong, and this forum is not the place to diagnose it. Just because we know it has been bored and honed to .060" over stock does not mean it has the proper piston to wall clearance for your pistons. Many things can sieze an engine quickly and this could be one of them.
Do yourself a favor and take the thing apart before taking too much advice from an internet thread. I have been in the performance engine business for quite some time and this is not the place to learn...

 

I had a wrist pin sieze up inside a piston,it was pressed on dry.Try pulling the pan and un hooking rods one at a time to see if the crank will turn

 

Last time I saw one that did that it was due to a blocked main oil passage....

Since you got two miles, enough time for the ass lube to go away, I suspect an oil issue this time too....

And, after reading the ".060 over" part twice, I got it.... I guess some folks didn't...

 

"I have been in the performance engine business for quite some time and this is not the place to learn... "

JUST WOW ^^^^^^^^^^^^^^^^^^^^^^ Pretty ignorant remark don't you think!

 

Sorry for the typo .60 should be .060

 

This is a great place to learn but for the original poster i believe its autopsy time.

 

" Pretty ignorant remark don't you think! "

Now why would that be Brigrat...? A little friendly advice to our friend with a broken engine. There is clearly not enough info for any of us to diagnose the real problem. He needs to take it apart before it costs him anymore time and money, dont you think?<!-- / message --><!-- sig -->

 

I didn't see anywhere in Merc cruzer 1st post that asked what happened, he only asked what his next move should be before ....... "I pull the engine"

 

rag in the oil pan??

 

It's pretty clear he meant .060

 

I am sure your intentions are good BUT JMO he needs to do simple little testing first, it may indeed be more involved but it cost nothing to check a few simple things first ...........................

 

You built it or a shop put it together? Hard to say what went, but a main bearing is a possible.

But here is my bet, you broke the timing chain. Let us know what happened and good luck.

 

Gee, I guess I should say sorry. The third post started out... "nope, pull it. sucks, been there."

Maybe this is better advice...lube the cylinders with penetrating oil, let sit over night, hook up neighbors tractor, put it in gear, and drag it around the block until it frees up...good luck.

 

[and this is not the place to learn....] You're joking right? There are extremely knowledgeable pro's here.......back to the OP...I'd pull the pan first.....

 

A couple months ago I had a flatty in the shop for a rewire, the first time I tried to start it the starter gear bound up in the flywheel and everything froze up. I was thinking the worse till I checked the starter engagement and after installing a healthy 12V battery al is well again. Simple things first..........................

 

There's been alot of talk in favor of break in additives brecause of the zinc being removed from oil which causes very early lifter, cam lobe failure, couldn't have cause this to happen so fast...

 

I'd loosen up the convertor and try and spin it before pulling it. Its gotta come off anyway and will make sure its a motor prob.

man sux that this is no place to learn,, I guess all the stuff I have gotten from this site should just be forgotten cause its all bullshit. Damn, thats a shame.

It really sux that many of us spend so much time teaching others a trick or 2, since thats all bullshit too.

If you are such a high and mighty engine guru, why not invest some of your vast wealth of knowledge with us. We are all here to learn and so far the only thing you've taught us is that you can stick your foot pretty far down your throat and not choke to death.

 

This may be one of the BEST places to learn!

 

ahhhhhh, those were the days indeed!

 

First things I'd check, pull the plugs and see what things look like. If you don't see anything there, pull the starter and make sure it's not locked in. After that it's about time to pull the engine.
And I've got to agree that you really need to sift to the info posted and figure out what makes sense and what doesn't.

Could have broken a starter but you can also break a starter if you hydraulic the engine.

 

I would pull the spark plugs as suggested, but ultimately it will lead to the engine coming out. If you don't have an engine stand to dissect it on, pulling the plugs in the car might be a benefit.

 

I did pull the plugs and nothing. I drained the oil and nothing in the oil. My next step is to drop the steering linkage and pull the pan and that will tell me where I am going next. I failed to mention this is a 1953 Mercury Flathead.

 

I'm done your not listning................................

 

Uhh, its a flathead

 

Man , I learn good stuff on here all the time ! Lots of good information and people that take time to help others . I hope it's something simple , I've had to pull out brand new engines and it doesn't feel good . It's worth checking all the simple stuff first just in case . It takes a smart man to realize he doesn't know it all and a not very smart one to think that he does .

 

CHECK THE STARTER as previously stated.....I'd bet some money [not much though] that the drive jammed..For an engine to stall from a bad bearing without making "any" noise? Take the starter out, might save you lots of needless tear down work..

 

disconnect the flywheel from the torque converter that way you know if it is engine or if the torque converter shelled out. I have seen this alot with them torque converters
