I have been advised my timing chain needs to be replaced. 100,000 miles seems to be pretty short for such an extensive repair. Is this typical? How does one determine it needs to be replaced?

Hi,

I have a feeling the person that told you that is thinking it is a timing belt. A chain doesn't normally go bad at this mileage or need to be serviced.

Often times, a worn timing chain will make noise, set different diagnostic trouble codes indicating timing issues between the crankshaft and camshafts, and a few other things.

With that being said, if there are no problems with the vehicle, chances are there are no problems with the chain. However, if you want to replace it, here are the directions for removal and replacement. All attached pics correlate with these directions.

A similar question was asked on your site it almost answers my question but not quite. I am doing an engine swap the new engine had a hole in the rear timing case cover XML add a week to the build had to swap it out with the blown engine's rear timing case cover once the new one was installed and I got the cam chains on. I had to rotate the crank over by hand to land on the compression stroke and find TDC, but it will not allow me to rotate a full 360 because the piston sounds like it is hitting the valve on the front middle cylinder the answer to. The other question said to install the main timing chain in order to turn it over, but I need to get the TDC in order to install the chain to turn it over I only turned it over by hand so I know the valve is not damaged. I am able to get to TDC if I could figure out why the engine will not turn a full rotation. Any information would be appreciated.

You will have to remove the cams and start from scratch again. Get the bottom end set up first using the timing marks on the crankshaft gear and then re-time the cams to their timing marks.

The car is old, but only has 35k miles on it and I am the original owner and have taken care of it. But I am worried because of the age of the car, but I also know that it has super low mileage. So is an old timing chain still a good timing chain when there is such low mileage. There is no rust and again the car has been very well taken care of.

I believe you have a timing chain so that is okay. If you have a timing belt it needs replacement as it deteriorates over time. Other things that go bad are fuel, brake fluid, auto transmission fluid and even oil. Fuel is especially unstable and turns to varnish quickly and causes fuekl sytem problems. Also check the intake tract to make sure nothing has nested there as mice and squirls are notorious for finding there way into intakes and even exhausts.

You have a timing chain for sure. I wouldnt worry about that. What size engine is in this? If its a 3.5, there is a water pipe that goes to your oil filter adaptor, they like to rot, and go un noticed until its to late. I would bring this to your local trust worthy mechanic, and have an inspection done. Im sure you wont find anything to crazy wrong with it. These are good cars.

Hey guys. I am loving your site. I was wondering though how I get my timing chain and the tension-er off? Because my car rattles from it so bad you can hear it about two blocks away, but I cant afford the shops quoted $1,500.00. I just need to know how do I properly open up the cover? How do I spot the tension-er? How do I remove the chain itself? How do I remove the tension-er, and is there anything else I have to remove or disconnect?

Okay, here you go I will do my best to do this over the internet and include pictures. Disconnect battery. Drain the oil and release the fuel system pressure. Remove the lower covers and then remove the right front wheel and engine side cover. Drain coolant and remove the radiator. Now remove the intake air duct and tubes label and disconnect the electrical connections hoses and cables needed. Remove the EGR tubes and the ignition coils and remove supports to the intake manifold. Get to and remove the intake manifold. Now remove the valve covers leaving hoses attached and remove the A/C compressor and alternator bracket and idler pulley bracket. Remove camshaft position senor and bell housing front cover.
