1999 Daewoo Matiz engine knocking very loud after i change the Oil

SOURCE: Loud ticking/knocking/rattling sound when I start/accelerate

hi is it miss-firing as it sounds like a knocking noise can be anything but if you can feel it on the accelerater pedal then the noise sounds like its on the inlet valve side which would transfere the noise up the throttle body where the accelerater is located it could be something as simple as a tappet come loose to a burned valve you need to have a look do a compression test and take the rocker cover off see if theres anything come loose yates210456

A loud low knock? And it sounds like a disel now, sounds like one of your rod bearings is going bad. Basically, unless you want to put a new motor in it or have the one in it rebuilt, the only thing you can do is drive it till it blows. Sorry to be the one to give you bad news like this, but your motor is old. Parts are worn out. You either have to freshen it up or let it die.

you might try and change the pcv valve, my car hand a similar problem in the summer and i never changed it. the pressure blew my cam seal and i was leaking oil like crazy. i dont know if it will fix it but they are cheap. i would give it a try.

sounds like a lifter my ford f150 does the same thing when its cold but then quits when it gets warm or it could be a weak oil pump. (just some thoughts)

Take our oil pan off from under your car and there should be 4 to 5 covers over a rod bearing. wiggle each one of them and find out which one is loose. take that cover off of the one that is wiggling and get the rod bearing out. order a new one from auto zone and replace it. The knocking in your motor can end up where you will need a whole new motor. so get it done before its to late.
