how should i go about starting my car after sitting.the starter went bad and i couldn't get one until now.i'm putting it in right now & i'm gonna change the oil but i wanted to start it first in case i flood.should i dump some atf or marvel mystery oil in the carb or plug holes?if so how much?

 

well, when I did the engine swap into the race car, the engine was sitting inside the cabin of the car for a while all plugged up, and before I installed it we put some two-cycle oil in the intake, rotated it, put some more in, and kept doing that till I was pretty sure we got all rotor faces. Then, once per day for a week we cranked it by hand to get that stuff moving and hopefully lube it up.

 

Yes, definitely stick some ATF in the engine. Pour some down the barrels of the carb, and slowly turn the engine over by hand. I let mine sit for a long time, and didn't do this. BAD mistake. One of the apex seals had locked up, rusted or carbon, anyway $2200.00 later I have a new engine. I think the ATF would have been cheaper.
just my opinion,

how far should you be able to turn a motor over by hand? And what do you turn by the flywheel?

 

Turn it one full rotation. No more no less. Three times.

Use the belts. Just give a good yank. Engine should turn, although it will be a good workout.

 

It just stops. after that one good turn?? if does that is good i hav been worried i scrapped my motor. becuase it would not turn more than one time.

Might be carbon locked.. Try turning the other way.

Or it could be compression and you're not strong enough. (Not raggin on ya. I had to do this too.) Pull the lower spark plugs out.

 

it turns both ways with fairly good easy and i can check the compression and it is good just turn so many times before it stopped. i was juts wodnering if it is supposed to stop may find out tonight cause i should be starting her up tonight.

 

No it is not supposed to stop. Find out what is lodging it stopped or you will break something when you start it.

BTW when I was in my REAL ****-retentve moods, when I'd do an oil change, I'd stuff the trans in 4th gear and turn the engine over by hand with the driveshaft. You'd be amazed how much oil is trapped up in the rotors, and comes out when you rotate by hand! Too bad it doesn't also work to get all the oil out of the cooler. 3k miles and the oil is dark black, change it with fresh oil, run it till warm, and the oil is dark again. Gotta change it 2 or 3 times to get it clear.

 

so it should not stop spinning i was turning by the fly wheel. And it turned for a while then stopped whill go abck for a while and then will stop agian this is while the motor was out. And now it is in the motor. we had started before we pulled it. could the air pump, alternator, or water pump lock because the motor ran before we pulled it. I will have to post some pics of my major renovations i did to this motor. needless to say i found a way to fix the bad thing that happend and it made it much more interesting.

I usually just pull the coils and crank it a few times. Never had all 4 wheels in the air during an oil change.

 

it's carbon locked then... remove the spark plugs and exhaust manifold if they're not already off (if they're easy enough to get to... headers - totally easy) and just flood the thing with ATF, work it back and forth carefully, let it soak, work it some more, etc. There should not be a point where it stops.

For comparison, with the spark plugs IN, I would easily rotate the engine with my index finger and thumb pressing on the alternator fan, and this was with slightly loose belts too. Our engines simply have no worthwhile compression unless they're running, which is why you should always set the handbrake - the cars WILL easily roll even if left in gear.

 

can i just soak it down with atf through the intake. I mean like a quart thorugh the intake. Would that work i just got the damn thing in and it will be baitch to take back out so can i just pour it in intake and plug holes and move it back and forth?? dan

 

for gods sake leave it in!! allyou have to do is get a small funnel and a bit of rubber hose. Pull the lower plugs out, atach the hose to the funnel, insert the hose into the plug holes and pour! As for the exhaust manifold, lift upthe front passengers side of the car and squirm under there with a wrench. it can and will come off if you are a bit persistant. then use the funnel and hose gizzmo again.


Personally I use a RC car Nitro bottle to add ATF to my car. It is a bottle with a metal spout about 6 inches long that fits perfectly in a 3 foot length of Fuel line. it works great and I have nevver had to pull my engine out to do this.

Just my .02

Don't turn it after it stops, that is the whole reason I need another 12A. Mine didn't carbon lock though, it hydrolocked. Always clean your engine with the spark plugs in.

 

ok put lots of atf in yesterday went out this morning it it just glided right over nice and smooth. So everything should be good i hope if not i will be pissed because i did some much work. I will post picks tonight.

dan

 

what is the difference between carbon and hydro lock??

EM

 

i was wondering what this is two?? ^^^^^^^


dan
but mine runs so i have no problems.

 

hydro lock - aka hydraluic lock - aka hydraulicking - the engine gets full of water or gasoline or some other liquid that can't be compressed. since it can't be compressed, the engine can't turn. if this happens with the engine running (like, say, going through a deep puddle with a low-mounted air inlet) it results in a few big engine pieces turned into lots of little engine pieces. if you're lucky enough that this happens with the engine off, just pull the spark plugs and crank the engine and stay away from the streams of fluid! cars with blown head gaskets/coolant o-rings will often hydrolock after shut off... we had a 2.5l chrysler that was BOUNCING coolant off of the 30' high roof in the shop when we cranked it with plugs out - the streams are powerful and dangerous!

carbon lock is when a chunk of carbon breaks off (usually after shutting the engine down before it's fully warmed up) with the engine off and wedges itself between a seal and a housing... usually between the apex seal and against the housing by one of the spark plug holes. you fix this by soaking with penetrating oil, ATF or MMO are good too, and carefully work the engine backwards and forwards until it can move freely.

 

Hydro lock is when it is full of liquid. This is what happens when a really low mounted intake gets in too deep a puddle. It sucks it up and since liquids do not compress - it locks up the motor. Can really mess things up.
I was interested in the low compression statement. When I first got my R1 I had it roll on me on a very slight grade - I noticed and stopped it., before I rolled into a nother car. I had thought it strange, but thought I had had a beer and messed up - maybe it was the car's fault!

OK,...

i think I have hydro lock, key word think, how would i definitively troubleshoot to see if this is the problem..

have already had the plugs pulled and the mech had to turn the crank and he is still alive! and he didnt mention water.or any other liquid... however the car did sit at his shop for two days prior ro him checking it?

UGH!
