I have to give you credit for being persistent ;-) but I think you may be putting the head down on the block before you make sure the cams are in the right spot. Check the pics I've attached, make sure all of these marks are as indicated before the head gets near the block. Any movement of the cams or crank after the head is bolted down should only be very minor in order to get the belt on in the correct spot. Make sure you compress the grenade tensioner in a vice and put the pin in before you try and put the belt on. With the belt on correctly and all it's slack at the tensioner roller, then pull the pin.i cant seem to get the timing correct on my 1.8L - b96ac6a.jpg53c84f7.jpg

Loking for illustration off chana star valve timing marks urgent and does if bent valves if putted valve timing incorrectly


Hi there
Well if you done the motor and you havent timed it correctly then you will get a knocking noise and dependens on the motor then yes it could bend the push rods or tight tappets or out of timing the valves can bend,hole in pistons bent rockergear etc.
But depends on the motor if you time it with number 1 piston is TDC number 1 and last valves rocking [depending on how many cylinders you have 4 /6/ etc and set distributor firing No 1

Have a 95 pathfinder v6. Was running fine and needed waterpump. My buddy is a mechanic and said he wanted to change the timing belt at the same time. He disturbed the motor by manually moving cams and...


You must remove the timing belt and reset all positions carefully taking care to not bend valves when turning engine. It is already possible you may have bent valves

I have just changed the timing belt on a 2001 Acura TL and now the engine turns over but will not start.


did you follow all steps in the FSM on this? if not, why not.
id never crank any interference motor over, with out checking
the timing 3 times, or 4th after sober, or after Cell phone died.
stop , take a break, or a nap , then check timing one more time.
and sparks out, roll crank by hand, no hit? and the 4 cycles.
of OTTO cycle, are looking good, per valve action viewed.
Intake, compr. fire stroke, exhaust, repeat? good a actions?
This last step is covered in all ASE classes on topic.
never just crank it. DOHC engines, or any that are known or suspected as being interference. (i do a leak down test, im so paranoid ($3000 new engines...make me that way)
its your motor. so....


what engine, there are many? world wide.......
Acura DATA?
Engine Interference Replace belt?
1.6(d16a1) Yes N/A
1.7(b17) Yes 90,000
1.8 (b18 all) Yes 90,000
2.2 & 2.3 (f22 and f23) Yes 90,000
2.5 (5 cyl.) (g25)Yes 90,000
2.5 (V-6) (c25)Yes 90,000
2.7 (C27) Yes 90,000
3.0 (J30) Yes 90,000
3.2 (C32) Yes 90,000
3.2 (SLX) (J32)No 90,000
3.5 (C35) Yes 90,000
3.5 (SLX) (J35)No 90,000

end data:


Let guess what happened? and what the right path is.
Interference motors.. (no context to your post so.....)
1: engine died.? did it? a KEY POINT THAT !
2: if find my belt , Tbelt all funky.
3: i put in a new one. (i time it 3 times, sober, no cell phones on ear)
4: i roll engine, by hand ,seems ok. ? yes.
5: i do a leak down test, on each cylinder at it's TDC fire points.
it passes, so i crank it.
it fails, oops, valves bent (stop , dont pass go or collect $200)

not doing this, in the correct order invites total destruction.
Unlimited,.....................................
google that , DOHC went boom.

Step by step instructions on timing belt installation 2000 hyundai accent


Right, so you have two TDC's-the exhaust stroke and the compression stroke Top Dead Center-and both occurr when the crank hits the zero mark on the timing scale.
Always set timing with the number one cylinder at TDC on the compression stroke. How do you know which is which? If you have a distributor, the rotor will be pointing to number one cylinder tower, when at TDC of the compression stroke. If you are on the exhaust stroke's TDC, the rotor will be pointing just opposite of number one .
If you don't have a distributor, look at the valves for cylinder one under the valve cover. If at TDC of compression stroke, both valves will be closed. At TDC of exhaust stroke, the exhaust valve will be open.
You can also find the compression stroke on number one by pulling out the spark plug for number one, and either put a wrench or socket on the crank pulley and turn it clockwise, or use the starter and bump the engine over in short bumps. Put your finger or thumb over the spark plug hole and feel for the pressure to build up. As soon as you feel pressure on your finger, (if turning by hand, pressure will be slight, but you can feel it) you are on the compression stroke. Stop bumping the starter and turn the crank on around by hand until the zero mark lines up on the timing scale-TDC of compression stroke! The exhaust stroke will have no pressure build-up as the piston comes to top-because the exhaust valve is open. On the compression stroke, both valves are closed as the piston travels up the cylinder.

Replaced the timing belt on a 1990 VW Golf and now it won't start but it will turn over


Most likely the timing is way off. The engine will start when it is in time and when it is 180 degrees out of time. The timing marks on the cam and the crank will line up correctly once when it is #1 TDC and once when it is 180 degrees out of time. The problem happens when you have the Crank at #1 TDC as it should be and the cam is set incorrectly in most cases. If both valves on the head for the #1 are not closed with the intake open and the exhaust closed for the next cylinder in the firing order your cam is not set correctly even though the timing mark appears to be correct. If the previous timing belt broke while the engine was running odds are every valve will need to be replaced because they are bent. VW did not use a no contact engine in this year model which would have locked the valves in the closed position if the belt broke. If this in fact the case you can verify this by doing a compression check on the cylinders. If you have 0 compression on any cylinders you have bent valves. You can also attach an air compressor to a compression check hose and apply air pressure to each cylinder, if you don't get pressure in the cylinder the valves are either bent or not closing properly.

Timing belt broke on car 1995 volvo 960 trying to retime. want to know is number one cylender up or down when retiming


The #1 piston must be at the top (Top Dead Center or TDC). Having said that it is still possible to get it wrong because the crankshaft turns twice to every 1 turn of the camshaft. Watch your valves as you turn the engine. The correct TDC occurs when the intake valve closes as you near the top and as you go past the exhaust valve starts to open. If the reverse is happening then your car will not start.
If you have an interference engine the timing must be done separately, the block with #1 at the top and the head with the valves opening in the right sequence before you place the head on the block. Otherwise you run a substansial risk of bending a valve or 2. If you already have the head on the car and discover the timing is wrong, remove the head before you try to correct it. A call to the dealer will confirm or deny the fact of whether it is interference or not. You should also send the head to a local rebuilder if it is to be checked for bent valves, before you put it back together. If you don't it will run like **** if it starts.
Hope this helps.

Step by step instructions on checking for bent valves and setting timing before installing timing belts for a 1993 Honda Accord LX


check the valve clearance. If you have valves with excessive clearance, then they are bent. the cam gear will have 2 flat marks that line up with the surface that the valve cover lays on, (9 and 3 o clock) and the "UP" sign at 12 o clock. the flywheel will be marked with a white line for TDC. be sure the balancer gear is lined up correctly.

How do I set the Balance Belt & Cam Timing Belt on a Mitshubishi 4g63 16v 2.0l sohc engine please?


tdc @ 1cyl. cam shaft has triangle stamp mark on face of the gear.both valves for # 1 should be closed in compression stroke and triangle should be pointing at left side top of head(9 o'clock) on the silent shaft and oil pump pulleys both marks must align with each other , use a metal rule for a straight edge.it would be wise to purchase a haynes manuel for your vehicle.this manuel gives you illustrations and step procedures to align all components on your g63b engine ....chris
