ok i went out to penn state to visit my gf this weekend. its a 6 hr drive. i drive straight there no stops and the min speed was like 65 and max was 90 as i pullin to the parkign lot at a slwo speed i hear this knocking noise. well i know where it was comign form and it was from the engine.

my last car was a 92 taurus and at abotu 119k the same thing happene so we replaced the motor. the knocking noise was consitant.

but in my car wehn i first started it today it didn't do it. abotu 20 mins later it came back.

oil was just changed has about 1000 mile on it w/ a snythic oil. the oil level is at the right amount.

im totally confused on what it could be my motor has 70k on it.

was told it might be the lifters, o a bearing. the car is not runngin sluggish or crappy. but i accualy seems to go a bit quicker. how i have no clue

anybody have any ideas what it could be
