Question
hello, Todd maybe you remember me about the overheating aztek, well the problem was : we change the both head gasket's, and cut 1/4 in. in each head bolts, then we fix the overheating problem, now when I'm driving the engine make's some noises, it start when i increase the speed, it sound like viper rattlesnake, what can i do for fix it?

Answer
Hi Mario:

yes I do remeber you not may people from MExico ask questions. Noises are hard to pin point. does it make noise all the time or do you have be driving it down the road. If the noise is there only driving it down the road then I would suspect possably a front wheel bearing. If the noise is there all the time. the it may be some internal engine noise possibly damaged from the head gasket issue it had? with out hearing it it's hard to say what indeed it could be.
good luck :-)
