SOURCE: timing chain broke

Hello,Bad Luck with timing chain failure,
Sorry to bear bad news but as far as I know Gm engines are NOT safe i.e. the valve miss pistons. It sometimes isn't too severe if very low rev's i.e. tickover, usually 2 or 3 exhuaust and same inlet. Let's hope no seats.
Cheer's!

SOURCE: When i set the timing on my 92 gmc 350 it sputters and backfires. Knew timing chain and cam.

yes a worn cam can cause it but it sounds more like timing off about 5 to 10 degrees

I have 2000 ls , took eng apart and found cam chain broke. and wonder what cause it to break clean? nothing is bang up.should i place cam chain and that be it or there more to it?


Very rare that a chain breaks. I'd replace the chain and before closing it up, turn the engine by hand and see if anything is binding or frozen in the valvetrain. Also look carefully at the valve springs to make sure that no valves have bent. (if bent, most times the spring will not return to normal height)

I have a 98 dodge intrepid 2.7L and i had a guy come over to help me replace the water pump and timing chain. after we took the timing chain off and replaced the water pump i noticed that he rotated the...


if he just turned the cams over by hand then i doubt that he damaged anything as if a valve was open when the piston came to top dead center then it would have stopped moving.the noise isn`t uncommon because the valves springs will make some noise as they are compressed and the rockers will make some noise as they move against the cam lobe and and the valves will make some noise as the valve spring forces the valve shut.if when you aligned the cam marks and they didn`t hit the pistons and stopped you from moving the cams and all timing marks are aligned then you should be okay to start the motor.

We took the head off an found that the valves are hitting the pistons on my 1997 chevy cavalier 2.2


Only way that can happen is if the timing belt/chain has failed and the cam and crank are no longer in phase with each other.

I need a diagram of timing chain replacement Thank You


During most engine rebuilds, a completely new timing assembly should be installed. If wear exists on any component, replacement of the entire assembly is necessary. Wear in the chain, gears, or sprockets means a timing lag, which results in poor engine performance.
The timing chain or belt is generally installed with the gears in their correct positions. Before installing a new chain, soak it in oil.
OHC (Overhead Cam) Engines
Some OHC engines use a chain drive; others use a belt drive. Removing the cover on some OHC engines that have timing chains is more difficult, because the cover often fits between the oil pan and the cylinder head. There are special procedures for replacing cam timing components in these engines.
Before a chain repair job, perform a leakage test on non-freewheeling engines to check for bent valves, so that an accurate repair estimate can be made.
OHV (Overhead Valve) Pushrod Engines
On many OHV pushrod engines, the crankshaft sprocket is installed on the crankshaft nose and the crankshaft is rotated to position piston #1 at TDC. At this point, a mark stamped onto the crankshaft sprocket is pointing directly upward (toward the camshaft).
The camshaft sprocket is then temporarily bolted to the cam and used to rotate the cam until a mark stamped on the cam sprocket is pointing directly downward (toward the crankshaft). The sprocket is then removed from the cam (without allowing the cam to rotate).
The timing chain is looped over the cam gear, the mark on the cam gear is positioned directly downward, and the chain is looped around the crankshaft sprocket. When the cam sprocket is attached to the cam, the timing marks on the crank and cam sprockets should be pointing toward one another. NOTE THIS IS FOR 2WD 4.0

Need timing marks for a 1996 pontiac grand am se 2.4 DOHC


YOU WILL SEE A HOLE IN THE CAM GEAR THAT A 3/8 BOLT WILL FIT INTO. PUT A BOLT INTO THE HOLES OF BOTH CAM GEARS. THEN LINE UP THE CRANK PULLEY KEYWAY AT ABOUT 12 O'CLOCK WITH THE MARK ON THE ENGINE BLOCK.

MAKE SURE TO COMPRESS THE CHAIN TENSIONER AND RELEASE IT WHEN THE CHAIN IS IN POSITION.

My 4.7 2002 dodge 1500 will not start


i purchased a new timing chain set and the cam pickup was bad on the new cam gear and we had a no start problem. i took the valve covers back off put the old gear on the cam and it started. BUT be careful if u do that you have to wedge the timing chains apart before you remove that gear so the hyd adjusters do not over expand. 4.7 dodge engines **** BIg they made them trying to save gas but the parts and repair over-ride any gas saving i got.
