can't take the slack out of a stretched chained if you already replaced just the tensioner

did you also look at the other timing chain guides?!? they're plastic covered as well & will eventually wear out in time

Hi there, the following information are for a 2004 Grand Am 2.2L, I hope it helps:

Look for some Youtube videos on this repair. If I remember correctly the links on this chain have different color metal for the spots that the cam tooth goes against. When each side is in the proper tooth the right and left colored links will be on the cam mark and the crank mark should be on the timing TDC mark. Sounds like the slack you describe is wrong and a tooth is off because the tensioner is allowing slack.. You need to slip a tooth one way or the other until the tensioner has room to be in a neutral position.

If all cogs and bearings are fine and that the chain tension is at specification then it should not be possible for the chain to ever jump a tooth. The amount of movement required by the chain to jump a tooth is considerable. I have only ever seen this as a result of an oversight when re-installing the chain after doing upper cylinder head work such as gasket replacement. Some models of vehicles with V6 engines that integrate the timing belt with driving the coolant pump can sometimes jump a tooth if the pump bearing fails. I would again check the chain tension once the timing chain is re-installed, even without tools you should be looking for a chain that is obviously taught. Not piano wire taught as this will lead to early failure but certainly one without any slackness or rattle. I have little experience of bike engines but the principles are the same

Check your owner's manual for the recommended mileage for replacing your timing chain. Replacement for a Nissan Maxima is 60,000 miles.2 Locate the timing chain. Replace it if the automatic chain adjuster (also known as the tensioner) is damaged or worn.3 Release the pressure in the fuel system, drain the cooling system and disengage the negative battery cable. 4 Undo the upper radiator hose, engine drive belts, power steering pulley and pump with bracket, air duct, passenger front wheel and engine side and undercovers, front exhaust pipe, cylinder head front mounting bracket and head cover, rocker cover, distributor and distributor cap and spark plugs.5 Take off the intake manifold support and move the No. 1 piston at "Top Dead Center" (TDC) of the compression stroke.6 Disconnect the cylinder head front cover, water pump pulley, thermostat housing, upper and lower tensioner and slack side timing chain guide, idler sprocket bolt, camshaft sprocket bolts, sprockets, mounting caps and camshafts. 7 Disengage the cylinder head with the manifolds, idler sprocket shaft, upper timing chain, center crossmember, oil pan and strainer assembly, crankshaft pulley, engine front mount and bracket and the front timing cover. Remove the oil seal and unfasten the timing chain cover, idler and crankshaft sprockets and the oil pump drive spacer. 8 Unfasten the timing chain guide. install Your Timing Chain 1 Grease the oil seal lip with engine oil and place it in the front cover. Verify that the No. 1 piston is at "Top Dead Center" (TDC) of the compression stroke. 2 Reconnect the crankshaft sprocket (marks should point toward the engine's front), oil pump drive spacer and timing chain guide and the lower timing chain. Line up all mating marks.3 Hook up the crankshaft sprocket and pulley, lower timing chain, front cover assembly, engine mount and front mounting bracket, oil strainer and pan assembly and center crossmember.4 Reattach the upper timing chain, idler sprocket (to the back side), cylinder head assembly, idler sprocket bolt and exhaust and intake camshafts. Place the intake camshaft knock pin at 9 o'clock and the exhaust pin at noon. Connect the camshaft bearing caps and distributor brackets and secure all mounting bolts.5 Eliminate any old material from the pan and cylinder block mounting surfaces. Rub on a 3.5 to 4.5mm bead of liquid gasket over the oil pan and cylinder block.6 Attach the upper timing chain to the idler sprockets and secure the cylinder head bolts.7 Refill the cooling system. Hook up the negative battery cable and any other disconnected items. Start the engine and look for leaks.

2.7L V6 engine? OK. is the chain broken or the tensioner not taking up
the slack? chain ok, just replace the tensioner, right side of engine, below
front of cylinder head. if it is the chain that broken, take it to a repair shop,
this will be and expensive fix, bent valves.
GOOD LUCK, RDJRP.

Need more info such as engine size.
