Loud knocking noise in motor..

I have a 93 tercel with the 1.5 12 valve motor. I just bought the car yesterday with 106,000 miles on it. It ran perfect until i had driven about 100 miles and I started to hear a loud knocking in the motor. It does it all the time when I give it gas but when I let off it stops. The cars performance doesnt seem to be affected. I checked the oil and it is full. What could be causing this?

Doesnt anyone have any ideas?
you should take it back cause most likely the engine it ready to go
slow down a minute, I wouldnt go that far......

I have a '92 with the same problem (i think)

Not really a LOUD KNOCKING, so much as a loose rattle type pinging thing.

happens over, say 2300 2400 rpms.

MY mechanic said it was the valves not to worry, I told him i was worried, so he fixed it, sure, lasted great for a day or two, then it came back.

I havnt gotten the chance to go see him again.
Maybe ill do so today, ill get back to ya

This isn't a pinging noise, it is a loud, very obvious knocking that seems to be coming from the top of the motor. I called the dealer today and he is coming to look at it.

How much can I get the exact same motor and transmission for from say a junkyard? And how much would a mechanic generally charge to swap the engines? Thanks for the help.
For the price a mechanic would charge to swap the engine, you could put a j-spec engine in there and pay the same installation. If your interested, give Back Yard Productions a holla and ask for Trevor, he'll take care of you. Any loud knocking is not good, rod, pistions..etc. Never good.

my paseo started knocking it was a main bearing knocking is bottom end can also be a rod bearing. best to just pull the motor and get a j-spec 5efhe and drop that in.
Why does everyone want me to put a j-spec motor in? Whats the point?? Its a tercel!
Which makes it the best, unexpecting sleeper around with a kick ass pounds per horsepower ratio.
5efhe or 4e-fte ? I guess 5efhe would be less trouble... it all depends on what you where planning to do with your Tercel. And ignore people telling you it's just a Tercel, there just as ignorant as the ones who say it's just an old corolla from the 80's.

People who dont know shit about : weight ratio, balance, camber, torque, peek, air restriction and can only say if a car is cool by how much horsepower it's got.
oh, i dont plan on doing anything to it at all. to me its just a car to get from one place to another.

doesnt doing all those mods screw up your gas mileage and everything, thats the whole reason i bought a tercel is because its supposed to get 35+ mpg.
