So, after having my trans/diff rebuilt at Shep the shop that has my car reinstalled the motor and trans. Went to start and all it does is click, swapped a well known good battery and had the same result.

Put a wrench on the crank and the motor wouldn't budge, the wheels (while up on lift) turn freely. You can shift through each gear without issue.

The shop pulled the motor back out and put a wrench on the crank and it STILL won't budge. The car has only sat for 3 months with a recent oil change (just prior to diff grenading). They took the starter completly off, same result.

The motor is completely stock and was never pulled apart. What are the chances of a motor "seizing up" from just sitting there? Any other thoughts? Suggestions? The motor has 25K miles...

It sat full of used oil, or new?

 

[Jkapinos]

Why was the motor out of the car?

I changed the oil about 2-3 weeks prior to diff grenading...

Easier then dropping the subframe if you have a lift and cherry picker.

sounds like the drivetrain is fine but your motor isn't. Maybe the diff grenading harmed the motor somehow?

The motor was running fine when I DROVE it up to the tow truck... So I don't think the diff did anything.

 

[kelvar13]

yeah thats a doozy. the crank not moving freely is concerning. That tells me something isn't right. Was the motor stored indoors for the 3 months the car was out of commission? You may want to consider pulling the head to check the cylinders.. not sure what else to reccomend.

Car was outside. Motor was inside shop with all holes plugged up.

 

[lallen3]

That tells me something isn't right.

Uh, yeah.





Stock?, did they try pulling the plugs and cranking it by hand?

Maybe trying to put some penetrating oil in the cylinders and see if that loosens anything up.

Pretty much this is all you can do. Seems like it just needs to free itself up. I doubt you'd have any mivec/valve contact issues.

 

[spikester603]

Ive never heard of an engine siezing from being just sat there?

Have you tried rocking the car back and forward whilst in 1st gear? it will take two people to do this as the evo's a fatty, you should hear a click/clunk as the flywheel turns the crank a notch.

Dont wanna cause any more dammage but you could try bump starting the car?

 

[lallen3]

They need to get a breaker bar and a socket and spin it clockwise. It'll budge. It has to.

 

[Stock?]

Uh, yeah.

I don't know that they pulled the plugs but they definitely tried cranking it by hand with a wrench.

I suggested this today to them. Waiting for results...

Yeah. If the penetrating oil doesn't work im going to tell them to get the biggest wrench/breaker bar they can find and force it. If it breaks a piston then I have to rebuilt it anyway...

Neither have I... Its almost impossible as there isn't much moisture in the motor...

This is the first thing I had them try. They said it didn't budge at all.

Why clockwise? It shouldn't matter should it?

 

[lallen3]

Mivec is meant to be driven in one direction only. You *can* go backwards, but with the mivec actuators working against camshaft resistance, they may move enough to get close to a piston. Maybe even touch it, I'm not sure- but why risk it?

 

[Yxd68]

Personally, I wouldn't bother with penetrating oil in the cylinders - unless it's been sitting under water for those three months. Probably do more damage by using penetrating oil.

Take the gearbox off the block and see if it will rotate then. Since that's something that has changed since it last ran.

 

[lallen3]

He already mentioned the motor has been removed for this purpose..

 

[kakashi]

But is the transmission still attached to it?

 

[lallen3]

Dunno, but if the trans/clutch install is botched, then this would explain things.
