Here is the question you need to answer to answer that question: If you put "X" amount of money (maybe $5000 for a jasper motor or $2000 for a used one maybe); can you take that same amount of money and buy a different car that is in the same condition as what you have? IF the car has relatively few problems, you may be better to bite the bullet and put in a reman engine. However if you haven't done maintenance as you should have, have thin tires, thin brakes, weak suspension parts etc, then maybe you shouldn't drop a motor into it. Keep in mind that moving into another car has potential pitfalls-even new ones. A used car may be a time bomb like you already own. Wasting money on a new one is a foolish expense and when you have problems (even under warranty) the dealer may not take care of the problems in a timely fashion or in a civil manner. Especially now that new car are having record recall problems and the dealers are under pressure to refute claims.
It is not good for the engine if it is the original setup from the 1970's. Lead is needed for lubrication to the valves. A reconditioned engine can use unleaded fuel if the intake and exhaust valves and the seats are replaced.
It should be done every 6 years or 90,000 miles... so it should have been replaced 2 times already hopefully... if in doubt have it replaced... if that little belt rips you will Destroy valves and pistons... basically total engine detonation...
no
Yes it can bend valves, when the piston makes contact with an open valve if the belt breaks. It can also destroy the piston and crack a head. The 1996 Civic engine is an Interference Engine and as such will self destruct if the belt breaks. The belt should be replaced at 90,000 miles under normal conditions and 60,000 under severe conditions. It should also be replaced at 10 years regardless of mileage.
First things first. What year, make, model, engine, and mileage? When were the spark plugs last replaced? Short answer: Yes. They should be replaced as part of the major engine overhaul your car needs. There should never be any oil on the spark plugs. A little carbon buildup, perhaps, but no oil. That indicates a serious engine proble such as worn out piston rings, worn out valves and guides, or a worn out turbocharger seal.
No they should not be bent.If your timing belt (or chain) was not installed correctly,(valve train out of time)this will cause bent valves,as they can hit the pistons.A major overheat can also bend valves.
No actual life expectancy, when it needs replaced, replace it.
The idle control valve is not a maintenance part - use until you have a reason to replace. You'll know that when you have a engine trouble code that mentions it as having failed - or other symptoms.
Cylinder head where valves are-usually. Valves themselves, no. Antifreeze passes around the engine in special chambers known as galleries. It cools the metalwork of the engine and does not (or should not) enter any part of the combustion, or intake system.
Valves will clatter if the engine is overheating.Valves will clatter if the engine is overheating.
It is almost a sure thing that you have internal engine damage. This engine is an interference engine and when the belt breaks the pistons will make contact with the valves. You will have to remove the head and find out how much damage was done. The cam belt should have been replaced every 90,000 miles.
I had the same problem. I was driving down the road and all of a sudden the engine quit. It turned out to be the timing belt had broken in mine, timing belts should be replaced every xx,xxx miles or 5 years whichever is sooner, since this is called a zero clearance engine (no indents in the pistons for valves) it also bent 6 valves.
