Hi, Anyone from Sac, CA that knows a good place to get an engine rebuilt? I'm thinking it might be better to just get my H23 rebuilt then go with a JDM h22 for smogging reasons. (I've heard that if you have a JDM engine, your car won't pass smog whether it be test only or not. Is this true?) I did a compression test a week ago and got some really low readings out of the first cylinder. The results were 120, 210, 195, 190 (cylinder 1-->4), plus it blows black smoke out of my exhaust with I punch the gas. I get a burnt rubber smell and have this nasty black dust covering my bumper so I'm not sure what is wrong with the car. I've lost a lot of low end torque but it still picks up on the free way. Any ideas or suggestions?

 

Just probably have to get new valve seats or valve in the one cylinder...

 

yea i get ALOT of black smoke when i punch the gas too, but i think alot of cars out there does it, i would def think imma running way too rich, but i have being told otherwise, so if anyone are SURE about this, please let me know also, if i cover my muffler with my hands.. you will see alot of black dots, soon your hand wil be black. BTW if you gonna change the valve, change them ALL, i THINK honda recommand car owners to change them every 15000, but thats bs lolz, but it will show improvements if you do change them all once a while

 

if ur gonna spend more than 1500 to rebuild ur engine.. just do swap...

 

no matter what a rebuild will be expensive. i can understand your situation with the jdm motor. see what you can do to have it smogged. i'm sure people in cali have with jdm motors.

if not, a usdm h22a might be a nice option. longblocks can be had for $1500 with very decent mileage.

i know most import shops and regular shops would charge an easy $2000 for a rebuild using stock parts. and this is mostly for seals, gaskets, bearings. anything extra usually costs more. the labor is very expensive.

 

black smoke= running rich
blue smoke= burning oil
white smoke= burning coolant

Pretaining to the low-end hesitation, try adjusting your valves and timing.

 

how did you do the compression test?

 

Are the h23's slower than the h22's? I read somewhere they were but i dont remember how much slower, or lower in horsepower i mean, thanks
