please my people. i have 2.4 camry 2az engine and it has given me a lot of problems since i purchased it from america last year september which is only one year. the problems i am having with the care is camshaft problems. i have chaged it three times and it kept spoiling. it is making this crackling sound and it is very noisy. pls what could be the cause of this? the engine seems to be fine it is just this noise from the camshaft. i was told by a mechanic that the top cylinder is worn out that i need to get another one. but i dnt want to believe that. this car is in good condition except this camshaft. pls anyone with useful imformation should let me know pls.

Go and replace your engine. My candid advice. Don't thank me now but thank me later

thank but are u saying i can't replace only the top?

Why give the engineer and yourself headache. If you do a simple maths and look at how much you have spent, is not just enough to get you another engine? 3 cam shaft sprocket. You would still buy 10 pieces
