Hey everyone,

I've been a happy Honda owner for about 4 years, yet I keep asking myself why I didn't register to this site before.
Had a slight concern about a problem with my car. It's a '00 Civic and I' m currently running a D16Y7. Lately, it's been showing signs of power lost. Not to long ago, I had an Accord tailing me and I took off. We were going at about 110 and I remember changing to 5th a little late. Didn't check my RPM, so can't tell u if I was redlining. As soon as slowed down, I notice that my car hesitated to get to 60 mph, which I was able to do before on 3rd at 2500rpm. Now, I have to get up to 5000rpm, to get to 55mph. This has been continuing since. However, my oil level stays pretty constant unless I go pass 85mph, so not much burning there. But that loss in power is bugging the hell out of me. Car runs like ****. Transmission needs replacement, I know that for sure, but would that cause any power loss? I am currently leaking some type of oil, yet it doesn't smell like engine oil. Has the same color though. Its possible its tranny oil.

Any replies or suggestions are greatly appreciated. Thank you.

number 1 quit streetracing before you hurt someone!
you said bad compression, have you ran a compression test?

bazoOKA_ TOoth

Not yet, ill be stopping by the shop today for that, but I guess my main question is whether a dying transmission would cause compression/power loss? No signs of smoke, or loss in coolant. Ill be pulling the plugs to check for oil on them. Anything else I should do? Sorry about the racing, I'm in Cali after all. Los Angeles to be exact. Still, get ur point, not acceptable.

Then don't speculate your compression is low then. Sometimes figuring out problems online is hard enough, throw speculation into the mix and its even harder.

98civdx

^ exactly.
my guess would be yes on the tranny
how many miles? have you ever over reved it? possibly damaged internals.

bazoOKA_ TOoth

I've never gone redline. Ever. There is big rattling noise on the inside of the tranny. Similar to the knocking noise of a bad rod bearing. (<---been there before) Im thinking the release bearing is gone cause you can only hear it when let off the clutch. U press it in, the noise goes away. Damaged internals? What do you mean? Engine or Tranny?

Pothole987

that would be engines internals
if anything i would have to guess timing may have jumped a tooth

bazoOKA_ TOoth

I'll need to check timing. Does idle change drastically when rings go bad? Because my idle is good, constant. No change there. Revving the car, needle goes up and back down smoothly. Would rings affect these two things?

D16SiHatch

my old engine setup burned quite a bit of oil and my idle didn't appear to be affected at all. so i'd say no.

bazoOKA_ TOoth

Drove it home and it feels like its choked out. Out of breath. Very laggy. D16Si, wat setup did u have?

98civdx

i siad damaged internals simply due to you saying you shifted a little late, to me that means you may have reved to high, and that can cause major damage.

D16SiHatch

it was an a6/y8. ran fine for a bit but then started burning oil if you even got on the gas at all. checked compression and found cyl 2 at 60psi. figured that might have something to do with it lol. idle'd fine and drove it till i swapped the ls in the car.

bazoOKA_ TOoth

I hoping not. Ill get u an update once I have my mechanic check the compression. About how much will a leak down test cost me and how long is the procedure?

I ran my car from Chicago to Los Angeles when I first bought it from my brother. One of the cylinder was not workin throughout the entire trip. I think it was a bad wire or something. I had trailers flying pass me at about 90mph and I couldn't get pass 80mph. LS is OBD1 right? I would want any swap thats OBD2. B18 maybe.

D16SiHatch

ls was available with obd0, 1, and 2 electronics. you can take an obd2 engine for example and run it with obd0 electronics just fine. so even if you were to find an engine but its not the obd# you want, don't pass up on it necessarily.

bazoOKA_ TOoth

Well at least with the proper harness. Re-pinning any old harness looks like a bitch to do. Its wouldnt be the OBD i'd be worried about. A decent engine is hard to find, especially on a budget. Well worth it though.

UPDATE:

I pulled the plugs and they all seem to have oil from the top portion. The grommets must be bad. But this wouldn't necessarily give me all the power issues i'm having, right?

98civdx

i have no idea what a leak down test will cost, if you cant do it your self talk to some friends or a shop.

bazoOKA_ TOoth

When a TPS goes bad, what is the most noticeable difference in performance? My car will not pass 70mph. I read somewhere that the fuel filter might be causing the problem if it is indeed bad.

On another note, I have Seafoam'd the car about 2 times in the past 10 months. Is it bad? How safe is Seafoaming?

98civdx

a fuel filter could cause it to bog, becasue it wont be getting enough fuel.

seafoam is both bad an good. Its good becuase it will clean out all the crap you dont want in your engine, but, as in the case of my friends gsr the only thing holding it togher was the crap, he needed rings shortly after. It has been known to kill rings very quickly, if you leave it in to long. Personaly i would have never seamfoamed my car 2 times in less then a year, actually i wouldnt have all togher.

bazoOKA_ TOoth

Makes alot of sense. Similar to a knife stuck in someone. If you take it out you might end up doing more dmg than before. I never noticed any bad results after Seafoaming but Ill avoid it cause that chemical (which im sure is part water) is not good in the crankcase. Any input on the TPS being a problem?

98civdx

Any cel's?

bazoOKA_ TOoth

Cant tell u that for sure. Only because my CEL have been on for about 1yr and a half now. O2 Sensor problem. I have a D16Y7 and I had that Catalytic that sits in front of the engine. I swapped out that **** and put in a 3in exhaust. I had to get a MagnaFlow Cat that sits under the engine to replace the one I took off. It worked as a swap in the end but code never came off. I just have to get the right O2 Sensors. Do u happen to know what effects come along with a bad TPS?

bazoOKA_ TOoth

BUMP...What effects would be seen from a bad TPS?
