What is wrong if there was a clicking noise that got worse when accelerating and after three months the engine stalled and a loud banging was heard when trying to restart and the engine seized?

Answer 1

Probably the timing chain began to wear out and finally broke. Happened to another car of mine with similar engine. Its possible the main bearings or the rod bearings gave out and locked it up. You'll have to drop the oil pan and see if they turned. If they did its time for a new engine or atleast a rebuild. Its also possible the timing chain broke and the piston and valves clashed, for that the head has to come off. I have a 98 tracker. My engine started making a clicking sound. My dad has worked on alot of vehicals in his lifetime. He thought it was the timining belt breaking cause the sound was coming from there. I ordered the belt in, and he took the vehical apart to replace, just to find out that the belt was okay. But I got him to replace it. I phoned around including chev and they informed me to take it in and have it checked. I live 4 hours away to the nearest place I can have it checked. I wind up taking a day off so I can take it in, I filled it up with gas and I left. On the way over there my vehical kept on losing power and dipping to 50km/h and so fourth, the engine sounded okay but it kept on doing that. A normal ride that took 4 hours took 5.5 hours with a few minutes stop in between. when it came to going up a hill, it lost power, going up at 20km/h. Well I finally made it there. The service person told me that there was a few possibilities why this would happen and I told them to do whatever they have to do to make it run properly again, they even though it might have been the catalylic converter and they were ready to make a bypass by putting in a straight pipe to the muffler, they assured me it wouldn't damage the vehical. But anyway an hour and half later, they phoned me back and told me my vehical was ready. I came to the garage and they told me that all the problem I was having turned out to be the timing and so I paid for their service and went my way. The vehical was running ok. On the way back, my vehical seemed to have more power than usual and my rpms were normal, I thought that was probably what I was having a problem with. Well after 2.5 hours of driving home, my engined just went dead. I cranked it and it cranked okay. It was minus 30 degrees celcius, I was prepared but I was there for 3 hours and luckily I was prepared by grabbing winter clothing. Well i phoned home and my dad picked me up. I got it towed to the nearest town and I went home. Three days later, the temperature was back up to plus 3 degrees and I thought my vehical had froze because it was too cold. But we towed it back to my town. I checked everything, including the gas filter and pump and distributer cab to see if there were sparks. Everything checked out. My dad removed the spark plug and put a metal thing inside to see if my valves were working and sure enough it wasn't moving. He took my front end of the engine apart cause he thought the belt was broken, it wasn't. He checked the crankshaft and here a tiny little metal pin like thing he calls a key was worn out and no longer moving the engine. He got another of this pin thingy and he replaced it along with a cement mixing compound. He put everything back together and I never had a problem. Overall, check to see if the engine is cranking properly, if not check the timing belt and if it is okay, check that pin thingy, it is located on the crankshaft pully thingy.. I know it was a long story, but I just thought I'd let you know what I went through. If you would like to contact me, you may email me at rdjanvier@sasktel.net
