Ok i was told it was a 96 prelude but it turns out its a 92. It has 127k miles and its an automatic. I hear a slight knocking sound coming from what i think are the valves. What's the cost of getting the valves all redone? And what is the most possible reason for the noise???

old gas is one possible cause for knocking and rough running

15 year old hard abused 127k sell it and get something else if it needs valves it needs amotor and brakes and struts and exhaust and... and...and

Sounds like there could be sludge in the engine, especially if u haven't been doing regular oil changes and maintenance.

If it a slight knocking it is probably NOT a blown engine. It could be valves. It also could be a head gasket, or a oil pump leak. If your oil pump is not working right, it will not filter the oil to all of the part of the car and knocking will occur. A oil pump could cost as much as $ 1,000 or more depending on where you go. Find out if your exhast pipe is dripping water-if it is, you may need a rebuilt motor. Before you decide to get a rebuild motor, you need to find out what other condition your car is in. It is a 92 so it is over 10 years old.

i would suspect that you have noisy lifters you may find it's real noisy when you first start the car and then quietens down after a few moments caused by irregular servicing and or old age it's probably not worth fixing but could be improved with an aftermarket additive for noisy lifters [hydraulic valve lifters] plus regular oil changes.

i'd say get another car. don't trust those used cars beleive me i had too many episodes with used cars

It'll be the valves. Go to a local shop and ask how much it'd be to get them re-adjusted.
