You can be off by 3 teeth before the valves and pistons make out with each other. Timing belt tensioner makes a knocking noise too. If your valves were bent AT ALL you would have a misfire on that exact cylinder and check engine light would be flashing literally. Good way to tell a rod knock is too connect a 22mm socket to your breaker bar and rock the main pulley back and forth you'll hear a knock from the extra clearance in the rod crank connection, personally I remove the oil pan and push the rods with my finger they'll be sloppy loose feeling. You'll know.😎

Nice!! Thank man!

So glad I found this video. Thank you! I JUST got the sound today and timing jumped, making my pistons touch the valves

@@williamhamilton3359 of course it’ll fix it. If your pistons are hitting your valves you either have sticky/stuck valves, a warped cylinder, or bad timing.

***Assuming you're crankshaft was perfectly lined up as well, this is totally normal*** When setting the timing on many DOHC Subaru engines the marks will be perfectly lined up until you pull the pin for the hydraulic tensor. After tenion is applied it will move one cam roughly "1/2 tooth out of alignment". This is TOTALLY NORMAL. I've heard explanations such as "it allows room for new belts to stretch". Not sure if that's entirely true, but any Subaru Technician who knows what they're doing will tell you that this is all normal.

As many comments have stated as well, many Subaru engines allow for the belt to slip 3 teeth before you begin to make contact between the valves and the pistons.

The guy mentioning that above is correct from what I've also have heard, there is a video explaining exactly what he's saying.

My 15sti jumped timing 3 days ago as I drove, maybe 3 or 5 teeth and little to say I'm getting my engine pulled bc the engine is shot. Going to assess the damage and see if I should rebuild or buy a new one... (I bought the car 6 months ago and I'm still paying her so I have to keep her or my credit with hate me)

i think you have to be at least 2-3 teeth off for the valves to make contact with each other

I’m having the same noise and issue with my Subaru Outback Did fixing this get rid of the noise??

Bet ur making me get my hopes up

What does it sound like?

Any update?

We’re the valves ok?

Ah so the knocking sound on my 2.7tdi v6 maybe timing jumped, enough for it to still run, as cylinder 1 not closing on time and fuel pressure is maxed because of this? And not crank failure? Worth a shot!! Costs nothing to check it over

did you bend the valves?

How does it sound

First of all make sure your crank is TDC lol

Did the timing job fix your issue?

I second that request, how is it running? I got an 04 rex that won't start. Checked timing and it's off as well. Wondering if it's worth doing timing, or if I should just get a new JDM long block.

Great video thanks. Subscribed. I av a bugeye. I changing the timing belt pulleys and water pump. I turned the crank so the mark lines up with oil fuse. I noticed when this is lined up I get the double Marks on top cam lined up with top mark at 12 o'clock n singles point down. Basically it all lined up but they the wrong way around. So I turned crank again one more revolution n it still all lines up but they wrong...so 3pm postion marks are now 9pm but double Marks are not facing eachother instead rather point 12 o clock. What will happen if I just remove belt n line up marks properly? Engine had no issues before so I'm confused to stick to this timing or do it properly. I appreciate u vant advise without seeing but any general advice what would be an issue with turning the cams to how they should be putting on a new belt n pulleys? Thank u
