knocking or ticking?

IF its knocking..good by motor. If its ticking, could be a stuck lifter on its way out. Try running some marvel mystery oil right before your next oil change. That stuff help unclog ports and oil passages.

it felts like something is shaking a little.. you could really feel it when u start the car n when u turn the car off... n this start to happen after a oil change... i used to use greddy blue syn. but i could not get them anymore so i change to mobile one syn. on my last oil change.. could that be the reason..

is it a noise or just a vibration? if its a vibration check your timing and spark plugs. If its a noise then you may need a rebuild.

man.. NEVER put marvel mystery oil in your motor! if anything, run a little bit of ATF in you oil to clean it out, but i have a feeling theres no syrum that will help you. if you hold the throttle at about 3500 rpm or so, do you hear it?

^ marvel mystery is just about the same as ATF. Ive never had a problem with it.

no as soon as i tap on the gas it stop n comes back once of twice when im at a stop. you could feel a little vibration on the gas padel

remove the valve cover, and take off the plate thats above the timing chain. reinstall valve cover. make sure your oil level is good. see if that fixes it.

i wouls say rod knock off the bat, too, but it usually doesnt go away with gas, it will come back at a certain RPM. ****, it could be anything including the alternator. ive had those knock before when the bearings go out.

what's your temp gauge read. if it hot enough and you forgot to connect the knock sensor your car will do that.

iv'e used atf and that mystery oil with no success when it comes to sticky lifters mobile 1 is what's worked for me.
