please help,Crazy engine rattle!(long)

Hey guys, 97 lude,h22,140k it started a while ago and keeps getting worse..i will try to explain..... if im driveing and i just start to push the throttle just a little but kinda fast i get this quick little engine rattle, almost sounds like something in the bottom end is loose and rattleing, if i drive up a hill and hold my foot steady it will rattle so i press the gas harder it goes away and as i eas off the gas it will rattle but only for acouple seconds..im really lost here and im really anal with my car,i know its not exhast or the exhast sheild and ive tryed lookin for enything that woul make that noise and nothin. Just did a valve set,fuel filter, spark plugs and the damb thing only has a cold air intake....WTF and the compression is 185psi each cylinder.And im spart with hondas its all i will and have ever owned......Please help..Thanks

Um i had vibrating and it was my header pipe had busted lose in side the header caseing you might wanna try taking off the header and take a look. And correct me if im wrong but I thought compression was at 200 psi in ludes.

Hey man thanks for the reply i will look into it when i get a chance....I checked the service manual and it said 185psi and mabye thats wrong cuz i got 190psi so im not sure, thanks again.

u can always take her to the shop if that doesnt work oh yea and be sure to have gaskets.

Do you have a new header. My DC-S header rattles like crazy. It's the flex pipe.

Hey good call, i never really thought about the flex pipe but its a little more high piched almost like a nut in a coffe can.......thanks guys

My flex pipe problem (DC-S) made noise between 2500 & 3000 RPM. I made sure it was the flex pipe by wrapping the flex real tight with header wrap. Noise went away. DC gave me a new part.

On a car with your mileage I'd worry about the timeing belt tensioner. They're a known to be a potential problem on h22s.

i checked the bearing, its fine and i jsut did a T belt replacement, my A/C bearing is screwd but it really seems it only under certien loads like mostly up hill or,its a auto and if i put it in park and hold the brake and mash the throtle really fast it wil amke the noise....eny idea? youhave to MASH the throttle though uther wise it wont make that noise,thanks guys for your input.

Just a thought, my 93 had a strange vibration when the throttle was lifted. Turned out to be coming from inside the catylitic converter, and it was tought to find.
