Thanks for this, I did a head gasket on a K24A4 and couldn't quite get the timing marks lined up right for some reason. It's probably a slightly stretched chain, not nearly this bad.
I would be interested in hearing what you think about the BG products. They always give away the own and screwdriver with magnet and stickers but how actually good is the product to help clean a used but new to the customer neglected engine.. oil and gas cleaners..
I just put new valves in a k24 head on a 2012 Acura tsx today. A previous mechanic had somehow bent the valves while trying to find out why it was running poorly. I timed and assembled it, set the tensioner with all slack taken out of the chain and everything looked fine. Installed the timing cover and motor mounts etc., when I went to tighten the crankshaft pulley bolt the mother$^#%^ jumped time. I'm thankful it did it then because had it jumped turning it over with the starter it probably would have bent the valves again. What kind of crap timing chain is Honda using? I have had several different cars with chain driven cams with far more miles and probably less maintenance and more abuse that never developed any cam timing issues. My Toyota Previa has a 2.4 with 248,xxx miles. Sounds like a good running diesel engine from the clackety clack sound of the worn down teeth of the gears but the chain, I'm sure has plenty of wear, is still holding up fine.
I’ve got this engine and with regular oil changes this problem won’t happen. The K24 engine is one of the very very best. Like all engines, they need planned maintenance.
True, but I also heard that you have to check your oil level regularly! If it drops too far, your chain goes stretched... Mine Accord eats around 1L of oil / 4000km... And my trusty and rusty '98 Civic eats 1L / 1000km, so that's that. At least it won't get seized I guess :)
I have been less than impressed with this engine. It was widely used, but oftentimes in vehicles far to large for it's meagre output. For instance in the CRVs with AWD, it could not effectively operate due to the driveline losses and the vehicle weight. It also has a tendency to burn oil for some people due to sticking valve rings. It was extremely maintenance dependent, and requires a lot more intensive maintenance than most people ever do. Normally I trust the maintenance minder on the Hondas, but not on this engine. It should be roughly halved, so changes somewhere at 40% oil life remaining or sooner.
