hello

so i replaced the head gasket and now the car just cranks.

i'm pretty sure it is the timing. while i was taking everything off to change the headgasket i was able to slide off the timing belt. the way i put it back on was, i made sure it was on TDC on the pistons and then made sure the cams were TDC. I left 1 of the cams on and with the other cam i tilted it and slid the timing belt back on while everything was on tDC.

everything is plugged in 100% positive.

what can be the problem?

 

Double check your timing again. Check your fuses. Check for spark and fuel.

 

i do have fuel and spark

 

My money is one your timing, I would check that first.

 

if u think its the timing then turn the crank pulley so that the white line lines up with the line on the plastic cover then take off your valve cover and see if the came are pointing in the same correct direction

 

it probably the timing belt that happen to me

 

You have installed the distributor incorrectly. It can easily turn 180 degrees when it is out of the car. Try taking out the distributor to check that first.

 

Although it is definitely possible to have the ignition off by 180 degrees on some engines, its not going to happen with a Honda distributor simply because of the way it bolts/clips on... but good thinking

I'm going with your valve timing is off. The way you described how you dealt with your timing seems a little strange to me. You generally want to first line up the marks before removing it, then use a paint pen to mark spots on the crank pulley and cam gears for reference, then loosen your belt tensioner and re-lock it in full-loose position. The paint pen marks will make it easy to see if you have the timing off or not when you go to put the T-belt back on.

At this stage, I would go ahead and line up the crank pulley with the mark and then see where the cam gears line up (arrows on sides should be pointing straight up when mark on pulley is lined up with mark on t-belt cover [or if you have the timing belt cover off, there is also a mark on the engine block itself right under the Yamada logo]). Even if these do line up, use a 19mm deep socket to spin the engine counter clockwise several times around until your cam gear arrows point straight up. Once they are, check the crank pulley again to make sure everything is good.

This last step is to see if you have tensions in the right or wrong places on the belt.

Changing the timing belt is pretty technical, but its one of those things that if you're careful about it isn't hard to do at all. Another note is that you must keep an eye on both cam gears simultaneously while putting the belt on. If one budges even a little you're going to run into issues.

Sorry for the long post, good luck to you

 

Have you checked your firing order? That could also be the culprit. When I swapped my first motor four or five years ago my cousin got the order wrong. I never double checked it and we couldn't get the thing to start for like a week. However, if that checks out, I'd bet the timing is off.

 

I agree that your timing is probably off...you either didn't remove the timing belt correctly, or didn't replace it correctly.

 

Timing for sure, does your TDC on the COMPRESSION stroke line up with the "up" on the cams? because if its the other way, youre giving spark to the EXHAUST stroke. Your crank may need to be turned another 180 degrees i believe. Hope that helps?

 

Hey, I'm with everyone else. Sounds like a timing issue. Thought this might help. It's from alldata.
Picture 1
1.Position the crankshaft and the camshaft pulleys as shown before installing the timing belt.
A.Set the crankshaft so that the No.1 piston is at top dead center (TDC). Align the groove on the teeth side of the timing belt drive pulley to the ("arrow mark") pointer on the oil pump.
B.Align the TDC marks on intake and exhaust pulleys.
NOTE: To set the camshafts at TDC position for No. 1 piston, align the holes in the camshafts with the holes in No. 1 camshaft holders and insert 5.0 mm pin punches in the holes.
Picture 2
2.Install the timing belt tightly in the sequence shown.
(1) Timing belt drive pulley (crankshaft)
(2) Adjusting pulley
(3) Water pump pulley
(4) Exhaust camshaft pulley
(5) Intake camshaft pulley
Picture 3
3.Loosen and retighten the adjusting bolt to tension the belt.
4.Remove the pin punches.
Picture 4
5.Rotate the crankshaft about 4 or 6 turns counterclockwise so that the belt positions on the pulleys.
6.Adjust the timing belt tension.

7.Check the crankshaft pulley and the camshaft pulleys at TDC.
8.If a camshaft pulley is not positioned at TDC, remove the timing belt and adjust the positioning, then reinstall the timing belt. NOTE: After installation, adjust the tension of each belt.

Hope that helps a little. Let me know if you need anything else 1

 

very helpful avidyn

so i'm going to change the timing belt for the first time,

please correct me if i am wrong

- remove valve cover
- set to tdc
- remove/loosen crank pulley bolt
- remove the driver side engine mount, loosen the power steering pump, loosen ac+alternator belts.
- remove timing belt cover
- loosen tensioner

and it should slide right off? am i forgetting any steps?

 

You can tell when someone has never actually done the work on a Honda.


My bet is that you are a few teeth off on your timing. When I'm doing a belt I always put a mark on the gear/cam/belt teeth. Then when you reinstall the new one you just count the teeth between the new belt and the gears and you know it's right.

 

Yeah, that sounds right. Just make sure once you get the new belt on to rotate the crank a few times around to tension the belt. Then double check your timing on the cams again.

 

Whats nice about the LS is it has the 2 5mm holes in the cams and cam caps that sets your cams to the correct position. One other important thing is to turn the cams 3 teeth counterclockwise before you tighten the tensioner. After to do a couple rotations with the crank first though.

this is one of the most overlooked and important steps. the marks have to be right with the belt tight. sometimes this is a tooth different than how it appears when you're throwing it together loose
