So I need to do my timing chain is it difficult?? And what timing chain kit should I spend my money in did some research and they all varied from 120$ to 200$ just don't want to end up with some junk anyone with greater experience???

 

Don't think the 1999 2.7 use a belt

I haven't done mine so I cannot provide much info on the process.

 

why do you need to do it? they usually last as long as the motor does.

 

My 2rz (3rz's 5 lug little bro) has 263k on the original timing set

this.

as I understand it, you don't need to worry about the chain. Belt - different story.

 

I've never seen a timing chain that needed replacement even when I rebuilt the engine. If the chain is worn out the rest of the engine must not be far behind.

 

When chains of yore stretched the sounds from the front of the motor changed. L6 Chevys, AMCs, Datsuns and V8 Pontiacs and a V6 Mustang I've had all come to mind. But the newest of those was an '86.

And the rest of the engine in all those was just fine. Chains were considered a wear item, but since the motors were non interferance, and running issues occured before complete breakdown, it was not considered a PM/service item.

I can't recall of hearing of an issue with a more modern chain set up. I'm sure there is a deflection spec on it. I'd try to find that and determine status before digging in.

 

Its making a horrible sound at idle bought it like that..... thought it could use the timing chain and a valve adjustment

 

I wouldn't worry about it, more hassle than it's worth. Timing chains last the life of the engine, at least they're supposed to. If not you got bigger problems to worry about.

 

horrible noise is probably more likely to be coming from the water pump or power steering pump or belts
