88 Mustang 4cyl knock

My 88 Mustang 4 cylinder engine knocks when it is cold. When the engine warms up completely is seems to be running fine. I just purchased it and supposedly has 53k miles total. The sales man said that his mechanic said that it was carboned up and would run better if driven.

I have changed the oil and put some additives to the oil and gasoline to loosen valves, lifters and injectors etc.

Any suggestions.

Possible main bearings and it probably has 153k (at least).

Possible oil pressure issues.

Back to the guy that sold it to you and demand an oil pressure check with a reliable gauge. If it fails that test, make them eat the repair or give the car back getting your $$ back.

Actually, it's 15 bucks for the full check and that is an excellent idea .

Although cars with a lot of mileage DON'T necessarily mean they are bad

Depends on the owner, of course, Joe. My Toy truck with 160k miles runs just fine, but I've seen lots of vehicles with half that that were worth about $1.25/100lb for the scrap value.

unless you get written warranty the car is sold as is so you are stuck with the problems.

Not necessarily. Depends on the state and the laws.

Right, just because a vehicle is sold "as is" does not give the salesman license to misrepresent either the mileage on the vehicle or its material condition.

My first step would be to get the Carfax report.

If the actual mileage is misrepresented, go to the dealer and ask for your money back. If they refuse, contact the authorities for action.

That being said, if the mileage is right, go back to the dealer anyhow and talk to them and explain the issue and ask what can be done.

Depending on your state's laws and the situation, a court may be sympathetic to your cause and give you a remedy. Might take a while to straighten out...try to reason/deal with the seller in the best way you can first.
