Hey does anyone know if its normal to hear a rattling sound when deaccelerating from Vtec!? As in i go up to 6000rpm but dont shift and let go of accelerator,also sometimes does it when im accelerating up to 5000-6000 is this normal or what ! if not what is that noise! Thanx for any input im kinda new to honda's

i have experienced a rattling noise when hitting vtec and i found it to be a loose heat shield around the catalytic converter. try disconnecting your vtec and hitting the same rpm and see if it still rattles. check your heat shield and see if it is loose.

Probably the heat shield, record it if you want a better answer.

Im asking cuz im going to install a turbo next week but i never payed attention to that noise till now that i was driving with no music on! Thanx Everyone whos posting

if its something internal i doubt it would sound like a rattle lol probably more like a tick or a knock. how many miles is on your motor?

mortificationrock

Well i really dont know i just bought used from some import shop!! I think like 30,000-35,000!!! Motor looked really good from the head i mean nicest one ive seen!! But i mean what do you guys consider rattle and whats knock!!!?? Sorry dude if im confusing but im new to these hondas and just swapped my Vtec engine in and im trying to find out if it aint defective so they can replace it. Also how can u tell if Vtec is engaging or not! Engine specs JDM D15B THANX BRO

creep up in your rpms slowly and watch for it to engage and listen very carefully. sometimes you cant hear it engage but you should be able to feel it if your creep it slowly into higher rpms. a knock would be noticeable if you were sitting still and revved the motor up. if it has only 30k-35k miles you should be good for turbo.

Sorry i know its of topic but seems you are very knowledgeable and might be able to help me with that Second Is it normal for a engine to make a little bit of noise when in idle i mean my saturn doesnt do it so im just wondering!!! My engine currently has I/H/E. Is that just the way hondas are? sorry for the noobness

jonathan13

lol i know some but im not great. i just try to help as much as i can. is your check engine light on? if not then i am not sure why it would waste a lot of gas. if it is on take it to autozone or any other parts store that will check the code for you and see what they say it is. its normal for it to have a little noise when idling but not too much. if your going to turbo you should prolly have your valves adjusted before hand and if your not going to upgrade any internal parts keep the boost at 6lbs or lower
