I posted in other forum but got no real responses.

I finally got my motor back together and in the car, and when I go to try to start it, all it does is crank.

I checked:
-spark = good
-fuel delivery = good
-main relay = good
-grounds = good
-distributer = ok i guess but im still gettin spark. Installed correctly.
-CEL = none
-Fuses = good

I pulled the plugs, and they are covered in fuel.

Compression test = 120, 120, 120, 130 !!!!!!!!!!!!!!!!!!!!!!

WTF, im stuck. I have nothing else to check. The motor is new, head just resurfaced, new head gasket, ect ect. ARP studs torqued to 80 lbs.

How in the hell can my compression be so low and so consistant? What am I missing?

Thanks

BTW, I pulled an all nighter searching archives and found nothing that matches my case.


This is a golden eagle b18c with 10:1 compression pistons.

 

Sounds like you either put the cams in wrong or your injectors are spraying so much fuel that the cylinders are washed down with fuel. Check your valve timing and your coolant sensor connection. Coolant sensor has a lot of authority(fuel wise) when cranking. Those compression figures are very low. Crank motor with plugs out and squirt a litle motor oil into each cylinder to help rings regain their seal. You really should check for spark with an adjustable spark tester as this tests the coils ability to produce a spark that can jump a 1/2 inch gap at the plug wire. Also check ignition timing and make sure the screw didn't fall out of the rotor inside distributor. Good luck....3gdude

 

Thanks.

How can I put cams in wrong? You mean mixing the intake and exhaust up? It seems like there is only 1 way they will fit.

The injectors are stock, and worked the last time I started the car (month ago)

I cant check ignition timing until I can actually start the car to warm it up. The distributer screws are in tight too.

Thanks for the help so far.

 

Aren't B18's supposed to 10.6:1 stock? so the pistons youre using are Low Compression?

Maybe those figures are correct.

 

my motor is a gsr motor. stock compression is 10:1. Type R is 10.6.

No the numbers are not normal. stock gsr compression should see around 200.

If your intake cam was retarded, you would have la ower 'effective' compression ratio, that is, the compression ratio measured from the time the intake valve is closed. Having the cog off 1 tooth retarded would cause a pretty significant amount of effective compression to be lost and the engine may not start. I've learned this from changing timing belts and having the engine either not start or lack power after I'm done. The apprentice years suck. I think rechecking cam timing would be pretty quick and easy and is something you should look into.

 

Yea I keep trying to do the timing, but its so frustrating on an integra. No room to work I will continue tommoorw.

BTW, would this cause my spark plugs to get soaked in fuel with the retardation of the cam or skipping a tooth?

 

Have you cchecked your dist.? It could be 180 deg. backwards... just a guess

 

checked all that.

 

Yeah, its a bitch but you can do it with the proper tools. Your plugs could be soaked with fuel because if there is no fire in the combustion chamber the fuel is going to drop-out onto the cooler parts in the engine. And since the engine is not starting there is no fire.

 

are you getting spark at every plug? make sure wires are in correct order on your distributor... keep posting we'll figure it out.

 

yes I have spark, I have mentioned all this in the first post

BTW, I noticed that 2 of the sparks are orange, and 2 of the sparks are blue. Does this make a diffrence?

 

sure does

 

what difference does it make? what color are the sparks supposed to be? How do I fix it? The distro looked fine....I think.

 

valve adjustment?

did that 3 times

 

is your compression gauge good then? did you use a headgasket?

something obviously isn't right.

 

sparks are suppose to be blue.

 

ok so it should be a distributer problem then? That still does not explain the 120 psi compression across the board.

 

Distributor is probably indexed wrong and your cams are probably off a tooth or more. TDC your motor and try reinstalling everything again properly according to the manual. Did you even use the haynes manual or anything? I'm guessing you just ripped everything off and then just bolted everyrhing back on figuring as long as nothing moves it's all good? If you can't figure it out, it's best to send it to a professional. You can end up doing more harm than good by playing around (bent valves if the cams weren't properly setup)
Good luck

ive lined up to tdc at least 5 times already, distributer is done right. And ive done everything according to the my helms manual. There is only 1 way to install cams too so i dont think i messed that up.

 

i know this is a long shot but ive seen this work/happen before when engines sit to long..try this,remove each spark plug and put like a teaspoon of oil in each cylinder then button it up and try to restart it...you see honda's have low tension rings and when they sit too long sometimes they do that(low compression)

 

cool ill give it a shot

 

How do you figure there's only one way to install cams?? If theres say 30 teeth on each cam gear than theres 30 ways to install the cam. I can tell you this, my prelude motor has holes in the cams that line up with corresponding holes in the cam caps at TDC. They are in the caps that are closest to the timing belt. I still think your valve timing is off. Like I told you in my previous post, you should check spark at the plug wire with an adjustable spark tester not a spark plug. You need to know that the spark can jump a 1/2 inch gap.....3gdude
