I recently replaced the head gasket in my 95 civic. Since then ive had a crank but no start issue. I found my TDC by aligning the white mark on my crankshaft with the oil pump pointer. Yet, still no start. Upon opening my distributor the rotor was facing the number 4 plug after attempting to turn motor over. Can somebody please help me with this . Crankshaft pulley was replaced over a year ago by a shop due to bolt having to be drilled out . Im unsure if the camshaft and crank might be off when it comes to lining up for TDC . Im just can't think of what else this could be. And yes, car ran before head replacement.thank you for the help.

 

do you have the cam gear set to tdc as well?

 

My wife accidentally turned it freely with belt off . And the markings are no longer lining up. How can I get the cam back at TDC

 

Well turn it back.

 

Well that is the question. How? Using the three marks? Is there another way like using the rotor

 

cam gears will have markings which will be at 9 o'clock and 3 o'clock (wont be dead straight but lines up with the back on the timing cover) the gears might also have "up" and a arrow on it. The cams may also have a hole in the first cam cap so when you line it up you can put in a pin or skinny bolt or screw driver in so everything is lined up.

Take pictures for us if you have problems

 

how much of a turn? complete revolution?

 

For whatever reason that made me lol. Simple, elegant answer.

OP, as others have said there are timing marks on the crank pully and each cam shaft, there should be timing marks on the cylinder head as well. The timing is very important to get right.

 

Lets ask some clarifying questions here....

Did your wife turn the cam shaft with the timing belt off?

If yes, then you will have to take the timing belt off to reset your mechanical timing and then re-install the timing belt.

Second and probably more importantly, do you know how to set mechanical timing and do a timing belt job?

Thirdly, do you have a Factory Service Manual (helms manual) for your car?

 

ok so the bolt to the cam gear was loose it got retightened . Then the pulley moved . Im thinking the markings are no longer accurate bc of the bolt being retightened ..maybe tighter than before . Im trying to find over means of getting the cam at TDC. Like the keyway for my distributor perhaps . Now with lines at 3 and 9 my distributor end runs up and down yet every distributor I've seen for a 95 civic is side to side. Thank you for your help

 

yes the belt is already off. The crank shaft is at TDC compression stroke . I just need to get my cam timing correct . As I said I think the lines on the cam are giving me a false TDC . Is there ano method. That's what I'm looking for .perhaps the cam lobes? Another method besides using the lines that's what I need.

 

I need another way to verify that my cam timing is correct bc as I said I do believe the lines are giving me a false TDC . Thanks for all your help . And yes this is the 6th time I've had my timing belt off . Im just ready to get it right so I can have my car on the road again. The head gasket replacement wasn't even though it complicated to any degree but this part has been my downfall .

 

Take pictures of the cam gears. And if you have taken the cam gears off they will only go on one way. Don't worry about the distributor leave it out of the equation.

Pictures are worth millions in this situation for us too help you.

 

Cam lobes are downward on cylinder 2 which cylinder one is next in the firing order . The only aspect I'm concerned about with the distributor is the keyway . If it's up and down or side to side bc in that case I think I have it but the lines definitely don't line up.

 

To rotate the cam it's best to rotate the crank 1/4 turn to mid shift the pistons, then you can rotate the cam freely. Once done with cam, rotate the crank back to TDC (sole white mark in sites) to install timing belt.

The D15B7 cam gear has the word Up on it as well as a left and right mark on the edge that should align with the top of the head when in TDC position.

I don't remember off hand but I believe the D16Z6 cam is the same way.

Actually pulling up the FSM. D15B7/D15B8, Up mark and side marks level with top of head. D16Z6, Up mark and bottom mark with bottom pointer. D15Z1, Up mark and side marks use arrows on back timing cover.

 

 

D15B7 by the looks, you have the cam gear 180 out. The UP stamp appears to be at the bottom behind the hose in your picture. It is supposed to be above the level of the head in the "up" position.

Please see my previous post for FSM specific details as well as proper concerns that should be taken when turning cam shaft.

 

No its up..just old and worn that's all

 

Then if those two side marks are level with the top of the head like on the FSM page, then the Cam is TDC.

 

make sure the block is as well before reinstalling the belt

 

Ok here's my update . I was checking for spark and there was none so I looked over my fuses and 15a ecu fuse blown . Replaced the fuse. Now I'm sitting in my car afraid to turn it over in case it is out of time. Hash marks on cam gear are lined up with block. My question is about the cam lobes on exhaust side . They are tilted downwards. What should their appearance and position be when I am TDC cylinder 1?

 

At TDC1, all 4 valves of cylinder 1 should be closed. The rocker arms should be slightly slack.

You're not going to cause any (further) damage now that the ignition works. The valves would have already crashed whether or not the sparks fire.

 

so show us where the cam gear is at now...

 

What made the 15a ECU fuse blow ???

 

Haven't verified mechanical timing but he wants to jump into ignition....this is going to be glorious.
