You definately have catastrophic engine damage on your hands. These are not interferance motors, so you can rule out valves causing this problem. If you can only rotate the motor so far one way and another, then you probably threw a connecting rod. Go look in your haynes manual to see what that is.

A little background on how this car was running before would help. Did it ever run? Or did you get the car like this?

damn negative negative.

Well it COULD be a seize but not necessarily. For all we know hes got the car in gear with the parking break on. Think of the little things "i hate hacks". You gotta remember everyone in here inst a master toyo tech. Fighting compression shouldnt be that difficult. But ya never know, if hes not that strong, a compression stroke could be hard to fight.

I dont see were he said it was a 5spd or a auto, sounds to me that someone ran it out of oil and the engine seized, there isnt any holes in the block so if it throw a rod then it was done at low rpms, if it a five speed it wont turn over and push it off, get it rolling and pop it into gear, but then again it kind of sounds like its a auto.

And probly if the engine is seized it might just be cheaper to find a lowmilage engine to put in it then rebuilding that one to get it to work.

how can you find out if a rod was trown through the engine, and it is a manual transmission

suprabahamut · 05-26-2007, 11:23 PM

I looked at the starter today how can you find out if it is stuck do you have to remove the transmission

I threw a rod in my 7MGE at like 2000 revs. Half went through the no. 5 wall, the other have went down into the oil pan (punctured it) then up into the no. 6 and went through that pistons' wall. Afterwards, it would still crank over with the starter (and actually fire too). It eventually stopped starting (after obvious massive oil leak), but I could still hand crank it with a breaker bar; it just got difficult every now and then. One of these days I should take a pic of that no. 5 piston and post it up here; it's pretty sick looking.

A thrown rod doesn't always come out the side of the block. See if the pistons are all moving, even just a little and make sure there's nothing in the cylinders. The starter being seized is a definite possibility, same for a jammed clutch (if it died in a VERY bad way

) and a seized transmission.

Pulling the starter is the best way I can think of. As for the clutch, there's an inspection plate on the bell housing you can pull off to take a look inside. I presume the transmission's not the issue as I assume you had it out of gear when it was towed?

cre how do you tell if the pistons are moving can you look into the spark plug holes

I have the same problem as this guy exept heres the difference, my car was running fine other than i know my head gasket was starting to go but it wasnt overheating or anything i drove my car on my lunch brake a few days ago and then i parked it and i tried starting i after work and it njust clunks so we pulled it into the shop and watched the flywheel as i tried starting it and it will only move about an inch, i also tried turnign the crank by hand and could only move it about an inch , remember the car was running FINE when i parked it and only sat for a couple of hours, what could this be?

Your headgasket blew and the cylinder filled up with coolant as it cooled. Take the plugs out and I bet the car will turn over...
