in the video i'm adjusting the distributor and the TPS sensor to change the tone of the noise. If I had a light and voltmeter those would be set and i wouldnt be tinkering with them.. but since I don't and theyre not set they are great for changing the tone.

note. b18c1 swap into EH3.

possibilities,...

pinging.. since i have a LOT of 87 octane.. with a bottle of 108 octane booster. I think tomarrow would be a good day to buy some premium and pour it in.

knocking? I sure hope not... it is louder from under the car??

My uncle thinks its some exhaust leak... since i have no gasket on the 2 peice stock manifold seam and the manifold/cat isn't very tight...

or maybe something is just flapping...

or the valves.. oh god no not the valves!


someone help me =[ =[


note: it wasnt allways like this.. this started today. I don't even drive the car, its still on jackstands, I was messing with my throttle bodies (had strange TPS codes) and then the noise started)

 

it's not a knock that's for sure

 

it could be a leak. lol at first I though you were cranking away on the engine until I realized that the engine is already running. definitely sounds like the sound is coming from that back of the engine. You got a leak somewhere or something is rubbing againste something. I'm quite sure. I recommend you get the intake manifold gasket fixed and cat converter tighten up first. otherwise you will be running in circles trying to find the problem.
