i have a stock d16z6 with an apexi turbo kit. it died one day on the freeway. i got it to start again and again on the way home. it was making some funny noises like metal on metal. we decide to pull the motor and found out that cylinder 1 piston had a crack in it and 4 had bad rings. put in a new block and head. i bought oem honda headgasket and used the copperspray for alittle extra insurance. i had arp headstuds before and reused them. tourqued them three step 15, 30, then to 70. finished with the swap and now car wont crank. u can hear the starter whine but no cranking going on. timing belt moves along with block and head. thought it may have been starter so installed another but same thing. changed distributor and same thing. checked for spark with a screwdriver in plug wire, touching frame. all plugwires spark. sparkplugs are wet so fuel is not an issue. plugs are gapped at 34 for FI. did a compression test and nothing. a big fat 0!!! any ideas? i have run out of ideas and am really frustrated!! even swapped the old head back on and the same thing!! help me PLEASE !!!

 

either your head cylinder is warped (most likely not) or your cam is 180 degress over. did you put the piston rings back in? haha. maybe your cam timing.

 

well like you said, its most likely not my head cus i used a different head. i even put the old one back on to see if it amde any difference and it didnt. the cam cant be 180 degrees over cus the crank pulley mark is on the single white mark and "UP" on the camgear, is on top. there is a line on the camgear thats supposed to line up to the pointer on the cover and it does. any more ideas??

 

so if I understand you right it cranks but doesn't fire? Check your grounds. I loose or unconnected ground might be the problem.

 

well it doesnt crank. it turns but doesnt crank. the only thing you can hear is the starter whining. all you hear is zzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzzz. doesnt crank at all. from what i understand, you need 3 things for the car to start. spark, fuel, and compression. i have spark and fuel but no compression.

Have you done a leakdown test? Where's it leaking?

so you can turn the engine over by hand (turning the crank bolt), but when you turn it over with the starter it doesnt do anything?

 

i dont know how to do a leakdown test. whats needed?

 

yes you can turn it by hand. the only thing it does when you turn the key is make a buzzing/whining noise from the starter. the crank rotates but it just wont crank.

You have ZERO compression in all 4 cylinders? What do you mean by you can hear the starter whine but no cranking, but then you say the timing belt is moving? Is the timing belt actually cycling when the starter is turning the motor over? Are you doing the compression test right? You actually need fuel, spark, compression, and timing for the motor to run. Is your timing belt on correctly and setup properly? How much slack is in the belt? We need more info.

 

yup, a big fat 0. it sounds as though the starter is working cus the timing belt moves too. so that must mean that the crank moves too but it doesnt crank. you know how it sounds like when you start the car? well it doesnt do that. all it does is make a whining/buzzing sound from the starter, not a clicking sound. and yes you can turn the crank by hand.

for timing, i lined up the crank pulley with the single white mark using the pointer on the cover and that little tab that sticks out with the v-cut in it. for the head, i made sure the camgear was up and lined it using the line on the camgear and the pointer on the head, the one that looks like this /.

the dizzy cant be off 180 degrees cus it can only go in one way. you probably could put it in the other way but you would have to force it in by tightening the bolts. dizzy went in smooth with no problems. and it cant be the igniter cus we changed dizzy too.

i am using rc 440's with hondata. i even used the afc hack with a a stock ecu thinking the hondata might be the problem but same thing.

anyone else???

 

so the starter is turning the crank, but the car won't turn over. Your compression gauge, are you sure it's working? I bought a faulty one before and gave me 0 reading.

 

its like branks new. it was my friends and he used it maybe 5 times so far. we even stuck a rollled up tissue in one of the sparkplug tube, not all the way down, and it didnt even shoot out.

 

you're getting 0 reading on all 4 cylinders or just on cylinder 1? I had all 4 give me no compression, and my intake cam was off timing several teeth. I would check that, but it is possible your gauge isn't working.

 

oops, scratch that, i forgot you only have one cam.

 

yeah 0 in all four

 

if its 0 in all four, you have some timing problems, or you totally fucked up that headgasket. are you sure you put it to the first tdc, and not the second? that would totally cause this to happen.

 

the headgasket is brand new oem honda ($60). i used the copper gasketspray for extra protection.

whats the first, second tdc? my crank pulley actually has five marks. 3 marks together then 2 together.
they look like this when you look from the side of the car (...lll............ll...). i lined it up with the second line of the pair.

 

Ok the best way to dbl check tdc is to remove #1 spark plug(the one closest to the cam gear) and put a long handle screwdriver in the hole. Turn the motor over by hand with the 17mm bolt at the crank pulley. When the screw driver reaches its highest point you will have tdc. At this point the white mark on the crank pulley should line up with the v and line on the timing belt cover. The cam gear should say Up and be at the top. There should be a 2 lines 45 degrees on either side of the Up. You use these to help line up the cam gear to the head. I hope this makes sense. Let us know.

 

i would agree with the camtiming issue soudns like the valves arent closing to allow compression to build. By the way you headgasket will eventually leak with that copper spray that stuff is a honda head gaskets worst nightmare

 

hmmm....maybe i shouldnt have used the copperspray. but the timing is right on the spot. if i cant find out the problem by this weekend, then im gonna take the headgasket out and put in a new one without the copperspray. any more ideas?

 

remove the spark plugs and drop a little of fresh oil into the spark plug holes, reinstall spark plugs and try to start it

 

yeah ima try that tomorrow. someone from another board already suggested that and sounded good to me. i just took a short videoclip of the problem but have to find someone to upload for me. just keep and eye out for the link

 

possible bent valves? to tight on the valve lash and it's keeping some valves open resulting in no compression?

you said the head was new? or used? was it re-built? might need a valve job or re-surfacing?


dunno......sounds kinda weird.......

 

why dont you try push starting it just to see if it runs, check all fuses before you do this.
