What happens if the timing chain is off a tooth?
You’ll either be way high or way low if your timing chain is off a tooth. You should be around 170 PSI with that combo. Distributor being off a tooth won’t make any difference, it’ll just cause the distributor to be pointing in a funny direction when the timing is set properly.
When to stop a car if the timing marks don’t line up?
If you turn the crankshaft by hand in the direction of normal engine rotation and the rotor doesn’t move, suspect a completely broken drive. If the rotor moves, however, turn the crankshaft carefully until the timing marks line up at the block. If you encounter hard, sudden resistance, stop immediately.
Are there different timing marks on 06 3.6?
Also, there are two designs for the 3.6 cam chains and the timing marks and diagrams for the secondary chains is slightly different. I’m going to assume that you know this and have the correct timing marks for your engine.
What are the symptoms of timing belt jumped a tooth or two?
Symptoms of a timing belt that has jumped/skipped a few teeth: One Tooth: It will idle like normal and the exhaust will sound fine but cruise and WOT the car will feel like you’ve got no power and in most cases will hesitate and misfire. Two Teeth: It will sound like somethings “knocking” which is likely the pistons kissing the valves.

How to explain timing belt jumped a tooth or two?
Not sure if you’ve got a camera or a camera phone handy but you trying to explain what you saw with your timing marks is a bit confusing. Just take two pictures, one of your cam gears and one of your crank pulley and where its line up to TDC. It should only take 6 turns or less to get everything to line up like it should.
How does a cam off a tooth work?
Somehow when you lined up the dots on the timing set you was off one. When I built my engine the #1 piston was all the way up, the timing marks on the balancer were lined up, the lifters for cylinder 1 were all the way down, and the dots lined up on the timing chain.
Can a cam off a tooth be opened before TDC?
Unless you have odd cam timing or a major split in duration and lift, the 2 valves should be pretty close in the amount they are open at TDC. If the exhaust valve closes before TDC the cam is way advanced, if the intake valve doesn’t start to open until after TDC the cam is way retarded.
What are the symptoms of 1 tooth off on cam timing?
Symptoms of Being 1-Tooth Off on Cam Timing 1 #1 jonboyb. We were having some discussions around the shop regarding what… 2 #2 Whiplash. On some engines the engine won’t run. Some engines will run if off a tooth. 3 #3 TainterRacing. Interests: Have a ???? 4 #4 jonboyb. Just put the crank to TDC and make sure the cam dowel is…
Can a cam off a tooth be wrong?
Doesn’t mean the dowel pin hole is in the right place on the timing gear (should be just slightly past the 3:00 position- about 3:15- when you’re dot-to-dot) or that the cam is ground properly to spec. Yes, this is pretty rare stuff to be wrong, but it does happen. I had a timing chain set years back with the dot on the top gear off by 1 tooth.

What causes a distributor to be off a tooth?
Distributor being off a tooth won’t make any difference, it’ll just cause the distributor to be pointing in a funny direction when the timing is set properly. Another possibility is if your timing marks are not true to TDC (possible mismatch between the dampener timing mark and the timing tab). Nov 15, 2009 #5

Why are there marks on the timing chain?
Observations like this can be used to gauge cam chain wear and to determine when the chain should be replaced. Every engine will have specific marks designed into components to aid in the timing of the engine. These marks can also be used to get an idea of the condition the timing chain is in.
How many teeth does a cam gear have?
IMHO, it is a sorry way to compensate for the WRONG cam. A typical double roller timing chain set for a small block Chevy has 44 teeth on the cam gear and they cover 720* of crankshaft rotation (two rotations of the crank). Do the division and that’s about 16 crankshaft degrees per tooth.
When to replace the cam chain on a Moto?
When I set the plunger with the old chain installed the ninth tooth was engaged on the plunger. Observations like this can be used to gauge cam chain wear and to determine when the chain should be replaced. Every engine will have specific marks designed into components to aid in the timing of the engine.
