Engine noise!
Engine noise! My car was running good, except for the fact it had a bad lifter. So we replaced the lifters. The ticking went away. While the intake was off we also did the coolant crossover mod and put block offs in the rear. Then put new head gaskets (MLS) in and new head bolts (ARP) in and everything was running great. The next day after driving the car again, finally, I started to hear some noise coming from the motor. It didn't sound like the ticking it used to have when the lifter was bad, but it sounded like a deeper noise coming from down inside the motor. I had a friend listen to it and he said it sounded like the same noise his motor had when he had a bent pushrod. But he didn't have hardened pushrods like I do. If I spun a bearing wouldn't there be metal shavings in the oil? The noise gets louder and faster with RPM's and I'm almost 100% positive that it's not an exhaust leak. What are other things I can look for to help me find out what this noise is? any suggestions?
the noise is there when the motor is cold or hot. Taking the valve covers off and listening didn't reveal anything either. So I am rulling out a bent pushrod or loose rocker arm. I'm worried it's a connecting rod. Is their any other way of knowing if it's a connecting rod without taking the motor out of the car? would there be anything to look for in the oil?
yep. it drives fine and everything. but it is a very noticeable sound coming from the bottom of the engine. the car is still quick, but i know it should be faster. i thought lifters, but the sound is coming from the bottom. and when i shut the engine off i hear a clunking noise from the bottom after it stops. ive done a couple threads on here, but no luck. im about to get the oil changed and see what kind of **** comes out.
