SOURCE: Loud engine knocking on 2001 Ford Focus

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.

SOURCE: 2003 Ford Ranger ticking noise, not a ping or

THE ticking noise coming from the engine it just a 1 tick on idle at about each rev of engine,,and does it make any differance to the running of engine ,,Does it get softer when it gets warmer.
As it sounds like a loose tappet and being a oil adjusted tappets this thought of thing does come in now and again. and the best thing to do is to get a small plastic tube 25mm (or 1' ) and 2ft long and put it to your ear and listen at the top of the rocker cover ans see if the noise gets louder in a certen place ,as you will hear it if it is there..
Other wise it could be a Small end on the conrod which the piston is connected to.... lets hope not.
So let me know as soon as poss the answers to all the above. Ron

SOURCE: What causes a loud knocking sound in the engine?

without hearing the knocking noise its difficult to say as it could be a cam follower or a big end ,best advice is to check oil level then ask a mechanic to have a listen and see what he says

05 ford ranger started knocking then blew of radiator hose now it wont start

The knocking (as opposed to pinging) could indicate lack of oil or a bad oil pump. If it was the lack of oil then that, in turn, could cause overheating and a subsequent blown radiator hose. In addition, depending on how long you ran the engiine while it was knocking, you could have driven off a pistion rod cap while the pistion seized up in the cylinder. If the engine won't crank or cranks with some undesirable metal on metal noise you may have an engine job (or a new short block)in your future. My arm wave analysis may be modified by some additional information.

Oil pump

If the oil pump fails and the engine continues to run then there will be catastrophic engine damage and then the engine will seize.(this would be accompanied by loud knocking noises and possibly smoke and in some cases fire in the engine compartment) If this has happened to your engine then yes it can cause the engine not to turn over. but if you parked the vehicle and every thing was fine. then you came to start it later and it wouldn't start then no the oil pump will have nothing to do with this no start issue.
Hope this Helps!
