back again Honda tech lol...

once again ive been searching and searching and searching for 2 days now and can not find anything to help me out, on here or anywhere on the internet.

fixed my coolant leak I was having. car drove fine for a day. went to sart it to warm up the other morning and the car ran real rough. I turned the car off and started it again and it was still the same. left the car there for the day and just took the wifes car. now I go to use my car again the next day and it started up fine but started to make a noise I knew wasn't right and its hard to explain with out a video which I do not have. I had just turned the car and the noise started about 3 mins after I started it. I was listening to the noise and accidently touched my headers and they were boiling hot ( not cherry red hot but HOTTT) I burnt my hand on them. the car wasn't even up to operating temp.

I have a check engine light on, I check the codes I'm getting and its for a code 41. I know what the code means but I don't have any o2 sensors hooked up. that's just how I got the car a few weeks ago.

what would make my headers get really hot before its at operating temp?

could my timing belt and water pump be going? could it have jumped time?

im lost and I have no idea what to do. I don't have a ton of money to drop into the car and would like to try to pin point the problem so im only fixing one or 2 things.

any help is greatfully appreciated.

 

Your "operating temperature" is measured in coolant temperatures. Your exhaust temperature is measured roughly in terms of "hot" and "engine turned off". Your lack of O2 sensors is negatively affecting your engine's ability to run, and might be increasing your EGTs, but ANY exhaust manifold will be hot after 3 minutes of running.

 

I can see them being warm but not hot to the point where I literally have blisters on my hand. im from new York and its 32 degrees outside.

 

get the o2 sensor and check back. Lets clear all cel lights first. I know you think it could be a waste of money to get it and it might not solve the issue but that would be the route I go first.

 

I don't think its a waste of money, it just having the money to do buy it you know. I'm laid off from work right now and Christmas is right around the corner. but ill see what I can do.

do you know if this car calls for 2 o2 sensors or one? when I had the car on the lift I seen one in the collector of the header but I didn't see one anywhere else

 

It's a 94, it has one exhaust manifold (not multiple "headers), therefor OBD1, therefor only 1 sensor.

 

Hands are not a substitute for a thermometer, how many degrees is "hot to the touch"?

 

if you read my first post it says " I ACCIDENTLY TOUCHED THE HEADER".... not one did I say my hands were used as a thermometer

 

If you were to pour gasoline around inside your garage and ignite it would the temperature outside your garage have anything to do with how hot or how quickly your garage becomes hot?



It's holy f@ucking **** that hurt degrees!





eH.

 

I think its best you try to provide a video to hear how this car runs....

 

Don't post again until you clear all the codes. Fix all known deficiencies and then see if the problem remains. It's useless to look for any solutions until then.

 

If your header is actually abnormally hot, which is currently unclear based on the info you provided, then NOT having the O2 sensor connected is making the engine run rich and contributing to the problem.

 

And for added info, exhaust gas is in the range of 1200 degrees. How long do you think it takes for metal to get to skin blistering temperatures with 1200 degree gas hitting it? If you think it's more than 3 minutes, I think you need to rethink that through.

I know my little wimpy D15B7 with a stainless steel header gets blistering hot within about a minute, maybe less.

You got a bunch of other issues to fix first. Then maybe you need to scan with an IR gun to register your header temps.

 

On the contrary you said exactly that when you said that you touched your header and thought there was a problem with the engine...

Correct me if I'm wrong but, you have stated you think there is a problem with your car because you said the headers are hot?

Get the correct diagnostic equipment like others have stated and maybe people can have more constructive input for ya bud!

 

I've been using an infrared temperature gun, have I been doing this wrong all along?

 

Stop worrying about the header temp. They get hot very fast.

So no more about it.

On to the actual problems...
