That first video was starting it after 9 hours of sitting, second time it turned over. Got home waited four hours and tried to start and it really did not want to turn over this time, the time when it does start is because I hit the gas. Still likely the timing and tensioners?Likely chains and tensioners caught up with you... most of the first 2 yr production had tensioner - chain rattle at cold start.. a bunch got done warranty,, until Hyundai cut labor on job over 50%,, so we quit looking for them in hopes that only show up as customer took concern to noise.. still see 1 or 2 a yr anymore... seen one where fella would not buy the job,, he ended up trashing the engine when chains finally jumped enough to wreck engine
If you was local, I'd do it for $500 labor,, you buy all the parts and leave on front seat.. But I am hiding...
Have you got enough oil in the engine? Also might have a blocked pickup. There sounds like both timing chain and hydraulic lifter noises. When cranking you can hear a low compression cylinder.
oil level? oil spec? oil age?
sounds like oil is not getting around fast enough
Bought the car in March 2017 with 96070 miles now have 97400. Carfax had previous owner do regular oil changes at dealership. The car dealer I bought it from had an oil change/filter (checked oil when I was first looking to buy it) and new air filter put in. The window decal says next change due 98xxx miles.To add to ^ ,how many miles are on the engine and has it been well taken care of ? Are you using conventional or synthetic? On a cold start,a top tier synthetic oil will get through your engine quicker than mid tier oils and much quicker than conventional and synthetic blends. Consider switching if you are using the latter oils. There is more to oil than just lubrication.
I would be willing to bet the dealership used conventional oil.Good choice going to synthetic on your part. Are you using the High Mileage oil because the valve covers are leaking? Once you replace the valve cover gaskets,you may not need the High Mileage oil. If that is the reason and you like Mobil 1,once the HM oil is used up,consider going to Mobil 1 EP as it is better oil.
I posted and then saw your post on the 5W20 HM oil you have. Their 0W20 HM oil is the best choice between the two in more than a few ways imo.
Just using it because it says it is for cars with over 75000 miles, I was surprised because I think 97000 is low mileage (at least for 11 yr old car). High mileage I think 200k.as above - garage used cheap oil
you should replace with what you have or better still 0w20 and save the 5w for summer
