when i first turn the car on no noise then it warms up and it statrs ticking the ticking increases in speed with accelerator. what usually happens when you bend a valve or does this sound like a whole different problem.

where is it coming from?

 

[maz3da]

the top of the engine but i heard no ythis forum that people have had a problem with s flapper valve in the intake manifold i am rally hoping that is all it is.

I'll put my money on its your injectors. The injectors are REALLY loud in this car and they do tick faster as RPMS increase.

When my dad's jeep threw a rod, all I heard was a similar ticking noise, that I thought was just "The exhaust coming loose, I'll get it looked at on Saturday". Brought it in on saturday, and we ended up paying 8,000 dollars for a rebuilt engine. Not trying to scare you, but I'd get it looked at.

How many cylinders did the jeep have? I can't imagine throwing a rod on a 4 cylinder car and having the car continue to run. I know when I did it I punched holes in the block, lost oil pressure, and the car just wouldn't start. Of course it would depend on the type of failure and how catastrophic it is. Regardless, I wouldn't categorize a tick as a thrown rod, that would be a tap or a knock.

It was a '99 Jeep Grand Cherokee Limited with the V8 4.7. It didn't run very long after we threw the rod (maybe a grand total of 40-45 miles), but it did last.

Yea i just picture a car with 88% of its cylinders running slightly better than a car with 75% of its cylinders firing.

I'm having a very similar problem. I think it is the Acc. Belt Tensioner Assy bearing going out. You can easily confirm this by putting a long rod on it and put it to your ear and listen. Compare it to other places on the engine.
