I was driving my cr-v and it just quit. When you turn the key it spins like the timing chain is broken. I pulled the valve cover off and the chain looks ok and seems tight. (not stretched) I am perplexed. Any ideas? Was going to get a compression tester and check the compression tomorrow. Not sure that’s going to tell me anything. Wonder if the chain skipped or something. Rob><>

Hello there, sorry you’re having issues. Wondering if you could answer a few things just for a more general feel of what your CR-V is doing.
How many miles are on the engine?
Does the engine crank normally when you turn the key? As in does it sounds like it normally does when you attempted to start the car in the past, besides the no start issue?
Did it do anything out of the usual before the stall?
When you turn the key to the run position, just before actually starting the engine, does the immobi light (the green key) turn off or stay on?
How long was it since your last oil change, and how much oil is or was in the vehicle during the time of the stall? Do you generally keep a healthy oil change schedule?
Again, just attempting to get a better idea of the conditions that were or are taking place.
Hope to hear back from you soon.
There are about 220,000 on the engine. We change the oil about every 5k miles to avoid Vtec issues. No it does not sound normal when you crank it. My first impression was oh the timing chain broke. I stopped behind another car at a stop sign and it just died. When i tried to restart it it sounded like the timing chain broke. It made no other noises. The green key comes on and then goes out. It was due for an oil change and was maybe 1.5 quarts down. It had been making a sound like the heat shield on the cat was vibrating at certain RPMs but, I thought is was the heat shield… Rob><>

Confirm that the heat shield is in fact not rattling. Just give the exhaust a friendly palm slap or two, and see if it rattles. Based on that rattle at certain RPMs what I have seen before in 2.4l engines is this. At certain engine speeds the engine loses oil pressure due to low level, incorrect viscosity, or mechanical failure. Due to the chain being tensioned by the oil system, when it loses pressure the chain is loose. This will cause an intermittent rattle that will go away once oil pressure resumes, and may or may not be accompanied by a low oil pressure light. The chain can stretch, or skip time.
Since you’ve already had the valve cover off to look at the chain I would take a look at the cams to make sure they’re still in time. You will find a punch mark on each cam, and they should be in the same place on each respective cam.
I pulled the valve cover off and sure enough and it looks about 15 degrees out of time. I ordered a new timing chain kit with new guides and a new tensioner. Any advice on swapping out the chain? I’ve done a timing belt before but not a chain. How tough is it to get the crank pulley off? Thanks for the help… Rob><>
