Why Me?

[1990clipse]

Ive been slowly replacing my clutch over the past couple days and i finally got to put the transmission back in today. That all went smooth however, after mounting the trans I tried to turn the crank pulley (clockwise) and it went almost a full circle then it comes to a stop. it kind of feels like a bent valve is catching the piston but the car was running fine before i took out the trans. Im stumped on what could cause my crank to stop at that point instead of spinning freely. I took the trans, clutch and even the flywheel back off, and it still stops. Any suggestions?

The crank does not spin as freely as you think. When I did it to replace my lifters, it took a bit of muscling to turn it because of the cam lobes depressing the valves.

 

[1990clipse]

When i say that it stops i mean that it is colliding with something. I turned on it last week and it was tight but i could "muscle it around. now it is so hard that it scares me to put any more pressure on it. im pretty sure that if i was to crank on it, it would stop the starter from turning the flywheel.

check that your timing is aligned.

 

[92AWDHX40]

Yes make sure your timing marks line up, spin it a few times to make sure they all are in time.

 

[1990clipse]

marks are lined up right but i cant turn it a full revolution in either direction. i know that im not supposed to turn it counter clockwise but if i turn it clockwise until it stops then turn it counter clockwise it goes all the way back around and stops at the same position.

That sound's crazy. Everything's off including flywheel and it's still doing it?
Can you here it hit anything if so where it's coming from?

 

[1990clipse]

Whenever it comes to a stop you cant really hear anything, but it is a dead stop. when i say "dead stop" i mean that it does not get progressively tight until it does not turn, it just stops as if the pistons are colliding with something. i don't understand why it would interfere now after it was working fine the last time i ran it. do you think that i could have bent the valves just by turning the crank counter clockwise by hand?

Take all of the spark plugs out and then turn the crank by hand and see if that works.

 

[Butterfinger]

I highly doubt it if it ran before it should be fine now but I wouldnt start it till you got it solved.
No offence but this is probalby going to be one of those easy right in front of you thing's.
If you can't see anything start with the valve cover, than the oil pan, shine a light down your sparkplug hole's hope fully it,s visible


And why should you not turn it over counter clockwise?

did u remember to bolt up the starter? i had the same thing happen to me on my 2g. and it was cause i forgot to bolt on the starter , so the starter would get stuck on the flywheel

 

[1990clipse]

Ive always been told turning you crank counter clockwise is not a good thing to do. Is that not true?

The starter is not on so there is nothing to stop the flywheel.

 

[Butterfinger]

I don't know that's why I asked, just does'nt make sence to me.
But it leave's me curious.

The reason, I think, that some people say not to turn the engine over backwards is because they think that the timing belt could slip. I don't know if that could really happen or not, but I think that is what some people believe. Definitely take your spark plugs out and see, at least then it will turn very easily the rest of the way.

That's what I always assumed.

The tensioner system is designed in it's location for a reason. By turning the engine in the opposite direction of rotation you're preloading the belt on the opposide side- being the side of the tensioner. Now the belt would be loose on the side opposite the tensioner, giving the possibility of slipping at the crank.

Although with the plugs removed this wouldn't really matter as there's no compression.

 

[ontario AWD]

Maybe try taking your car out of gear?

 

[1990clipse]

Transmission is off.

 

[ontario AWD]

Just check your timing mark's,if there still on make sure the tranny spins freely.What would happen if one were to put a clutch disk on backwards?

 

[Butterfinger]

Just a dumb thought are there any alignment pin's in the end of the crank for the flywheel that could have got pushed through or any thing between the crank and block.

 

[1990clipse]

the transmission is off. no flywheel, no clutch, no pressure plate, no starter, just motor.

 

[ontario AWD]

Well for sure recheck your timing.

 

[GSeX02]

i feel your pain, i got my 95 and the turbo keeps giving me problems

 

[the_mork]

About what position is it in as it relates to TDC?

 

[1990clipse]

Now that I have Daylight and some free time im going to pull the spark plugs and recheck the timing. keep your fingers crossed!

Look man you wanna know if its a valve take the head off not a hard job get some new head bolts and gasket . It sounds like a valve to me and if you take the head off you will know for sure it's only about 70-100 bucks and a hour or two to do. then you will know for sure what it is.
