so today i got a knock... i need input. slight knock at start up, knock not under load,non at idle, and getting on it. i just had my oil changed and the valves adjusted bout 4k ago. from what i have watched on youtube, it sounds maby like a timing chain? not sure tho. its not a tick its a knock. i have 109k on the car and im the 3ed owner the owner b4 me, lets just say he liked vtec but took realy good care of the car(i know him) so not sure stressin out bout it, i also have a BS ticket to pay and dont need car problems right now. any imput would be great thanks.

 

Without actually hearing the knock or ticking sound in person, its really hard to make the right suggestions, have you already try searching the "under the hood" threads?

Whenever this question comes up, the usual suggestions are:

1. Maybe it was bad gas, so drive it real easy, don't vtec, and when you're at about 1/2 tank of gas left, try adding like a gallon of race gas, or few bottles of octane boosters in your tank and see if the knock goes away.

2. You mentioned you had a recent valve adjustment. It could be that something was torque to spec, so maybe a valve ticking sound. The timing chain sound is nothing like a knock as you said, it will be hard to mistaken the two.

 

Yeah, its really hard to diagnose the problem without actually hearing it.

How long did it last for?

Did it sound like a bottem end rod knock?

It might be the start of your tensioner going out. Mine is and its not the average "ticking" sound you'd hear come from the head. Its loud, almost like a diesel engine

 

Tensioner noise is very easy to discern though....very fast paced "chatter". My tensioner has been a chronic problem. It's very easy to pull and rewind, reinstall and you're good to go...for a while.

 

from what 2 of my good car buddys said, my number 3 cly. is knocking. they think i just spun i rob bearing. buts its still doin it

 

does anyone know any good places to buy internal parts and get the quick? for a decent price???

 

You need to have a professional look at your car. That way you can be sure on what is going on. Don't spend money or time looking for parts you may not need.

 

yea its the rod bearing. i took it i after i got off work to the only car shop i trust down here. so im hoping its not to damaged

 

so after talkin to the shop owner where my car is, we came to the conclusion that its goin to have to have a new crank and bearing, maby a few miner things. we found the problem

the bearing flatened out and was losing oil pressure. you can see it there. would a oil cooler help ya think?

 

no an oil cooler wouldn't be the solution for this problem. Solution to this problem would be making sure your oil is full, don't over rev. on down shifts, and make sure you have correct oil pressure. And of course whom ever is assembling the engine must do it correctly in order to insure that pore clearances are not a cause for engine failure.
