We changed the timing chains and the guides. Now the car wont start? We are thinking it's not in time. I have gas and a little spark. When I am trying to turn it over it turns slow. Do you know if the left cam should have play in it? Any ideas

Yes it does sound like you got the timing wrong and the camshaft I would double check the marks and then goes from there.

Here are some diagrams that will help you see if you are off or not?

Please let us know if you need anything else to get the problem fixed.

Cheers, Ken

My owners manual provides no information on the manufacturer's suggested time to replace my car's timing chain. After what number of miles of operation do you suggest that I should replace the timing chain in my car?

Your vehicle uses a timing chain, chains don't have a specific interval to replace them. Chains are supposed to last as long as the engine.

Replaced timing gears/chains. Car runs good above 1000 rpm. Idles rough when braking or sitting in drive/reverse, smooths out a little in neutral. Also replaced plugs.

Noises problem
2000 Nissan Altima 4 cyl Front Wheel Drive Automatic 102300 miles

I have a dull roar coming from the engine, I can't pinpoint it but saw on consumer reports about lower timing chain guides are a common issue with the Altima. They also mention a broken BTV valve bracket. What is a BTV valve and where do I find it. T-chain guide is probably a big job and I may not tangle with it. Like to work on 'em but know my limitations. Any help about the location of BTV valve and what I can expect if I try to fix the t-chain guide would be helpful. Thanks. Kevin.

Remove the valve cover and look for the broken bracket. I dont know for sure but I remember having one of these altimas with a 4 cyl making noise like it was a timing chain and I removed valve cover and found something broken or loose and I removed it and that fixed it. I know it doesnt sound too professional but I just cant remember exactly what it was but I remember it was a easy fix after removing valve cover. Hope this helps
