weird noise in the engine..... PLEASE HELP!!
hey guys ive been hearing a really weird noise in the engine lately. it never used to do that. me and my mate (who is a mechanic) replaced the water pump last week. but in the end, we couldnt finish the job because we need a rattle gun and he doesnt have it on him. but before that, while we were trying to get to the water pump, he was spinning this big bolt and it made the cams turn. after doing that, he accidentally jumped that timing making the timing to be a bit off. so we did not start the car at all and seeing that we needed a rattle gun to take off that big bolt, my car had to be towed to his workplace. so my car was left at his workplace for the next few days. since he had to do other jobs as well, my car couldnt be done in time. so his boss, fixed the timing and got the timing right again. my mate finally worked on my car and changed the water pump and started putting stuff together and thats when i arrived at his workshop. we started the car up and it started to make this weird noise. it sounded like the engine was dry. was making thing tractory noise. but we left the car running for like 5 mins or so and the noise disappeared. but when i got to my gfs place, i was parked on a slope and it started making the same noise again. so i decided to just leave it. finally i went home and park the car on the driveway and my driveway is also on a slope and it made the same noise again. after that i decided to let the engine cool down, and started the car up and park it in the garage where its flat and the noise was still there but not as loud i guess.
so if anyone out there knows what it could be, please let me know. i am just really worried about this. :(
