I'm Jordan, I have a 1995 Honda Civic with a D15, It's fairly stock with the acception of some no-name short ram and some whatever exhaust headers. I just got it a few days ago and I was wondering if you guys could help me solve whatever is wrong with it.
It is smoking a lot (burning oil, blueish smoke not white coolant smoke) and I'm pretty sure that is due to piston rings. It feels like I'm losing power after about 4K RPM and it actually hits a rev limiter at 5.5K. I have a check engine light on, code 7, (Throttle position sensor). Could that be why it's limiting? I know a little bit about hondas from fixing up my last car which was a POS DA9.

I'm pretty sure I have two issues going on. I think I'm losing top end power because of the lost compression from the rings. But is it supposed to be rev limiting at 5ish? Shouldn't it rev limit on the redline?

Any help is greatly appreciated!

 

Hmmm. First of all, which model car do you have. It's probably a d15b you have in there, which is a vtec motor. The rev limiter in that car is 7400 rpms, and the vtec comes in at 5,000 rpms. It sounds to me like your vtec isn't engaging which would be why it's SLOOOW as *****. Perhaps your vtec solenoid isn't engaging.

Hondas typically blow oil (moreso the older ones). Especially in vtec. But if your vtec isn't engaging it could be blowing it more than it should be in the higher rpm's.

 

It is (I think) an LX. I just checked and your right it has a D15B in it. Could someone direct me to how to check my vtec solenoid? Wow, I didn't know I had vtec hah.

 

What are the first 6 digits of the vin number? that will tell us model you have, and will help us figure out what we are working with.

 

it can also be a non-vtec d15b.. or a 2-stage vtec d15b

 

The first six digits are 2HG EJ1 and the engine says D15B8..

 

thats a cx motor

 

Yeah I just looked that up. So if it's not a vtec, why is it limiting itself to 5.5K?

 

thats the redline on that motor, well the ecu which is a P05

 

Well, first you should do a compression test. That will tell us if you got one cylinder leaking or more. And since you know you have the d15b8, we know you dont have vtec.

 

Uh ya guy.. thats a 70hp motor that redlines at 4500 rpms. your probably killing the damn thing lol.

 

yea do a compression test on all cylinders. and man just find a swap even an ls motor is nice. thats torque up the ***. how much did you get it for. before i buy a car. i usually do a compression test. i then redline to look for smoke out of the exhaust thats how i know that the motor is till nice and listen to any knocking at 3k rpms. smell the oil to see if it smells burnt that way you know the motor isn't beat on or not. my best option if your burnig oil or leaking or need replacing here and there. just swap the ls is cheap and pretty nice.

 

Yeah, the rest of the car is in great condition so I think it's pretty worth it to do the swap.

I only bought the car for 2k

 

dude those motors are meant for effieciency..thats probably why you are maxing out at 4500 rpm lol get a d16z6 or go B series..

 

So I decided to go B-series. Probably LS/V or just LS for now, it depends on my money situation. Thanks for your help, I'm sure I'll have plenty of help on here.
