kinda not in the sense like lot ohc engines where valves dip into cylinders, but if your chain has broke pistons will hammer heads damage the pistons and everything

The 2002 Chevrolet Malibu has the 3.1mfi engine which is not an interference engine. It has a timing chain and not a belt. It is an o.v.h. system with two valves per cylinder. I have replaced timing chains and have had the heads checked, with no damage to the valves.

No.

if a 2.2 four-cylinder, remove the starter motor. disconnect the 7x crankshaft position wiring and harness connector. remove crankshaft retaining bolt and withdraw sensor from engine block. replace the "O" ring and lightly lubricate it with new engine oil. installation is reverse of removal. have a good one !!

you must check these.
1- IAC
2- injecters
3-valves cylinder
4-fule pressure
5-coil ignition
6-bult timing

The book time for 4 cylinder is 5.7 hours.The timing chain runs the water pump so this is a big job .If you do this make sure the timing chain is replaced also.

these are hydraulic valves, no adjustment needed, with both valves fully open u back them off until they (rocker arms) are just slightly loose, then tighten them 1/2 turn, follow the firing order of the engine and bring it to top dead center (compression stroke) for each cylinder.

water pump is no big deal ,thermostat that a bigger job there not mush room to work but why the timming chain were i work the owner got a taxi fleet all maliby from 200 to 2003 i never say in my mechanical career or needed to change a timing chain on a malibe those years some of malibu has close to 600,000km change a lot of intake gasket but timing chain never please tell why the shop whant to change the timing chain do you now the shop good thanks pierre

That engine does not have a timing belt, it has a timing chain and therefore much easier to work with as it can only go on a certain way, the primary focus being getting the dots on the timing chain sprockets lined up properly.

I believe, with the engine at Top Dead Center on cylinder #1, the dots will be facing each other. That is to say, the do on the cam sprocket will be facing the dot on the crank sprocket.
