engine will not rotate - Page 2

How about the starter is stuck out and in a position where it wont spin(there is a sweet spot)

Jjona5 · 05-26-2007, 05:46 PM

Or maybe a spark plug exploded in one of the cylinders and left crap in there...

Though its probably a mechanical failure...

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

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

suprabahamut · 05-27-2007, 01:52 AM

btwilson86 did you have to replace your engine or can you repair it

btwilson86 · 05-27-2007, 02:02 AM

I replaced the engine... JDM import. I figured that it'd be easier than replacing the block... The old one has two baseball sized holes in it (one on each side).
