Hi guys, ( new here, please advise if anything wrong)
I'm in a bit of a pickle with a 2015 Hyundai I40.
Bought this car back in November, loved it until I started hearing a faded ticking noise and after a couple of quotes went with timing chain to be changed ( have on it 260k km). Thinking this is the right thing to do I found a good place to do so and then problems started to raise up.
Little back story, had some hassle before with buying cars and thought this time I would get smarter, when buying it
1. from a garage,
2. with a mechanic that was doing this for the last 30 years. And even though the garage told me they full serviced it, I didn't want to take any chances and full serviced it with the mechanic that I thought he should know better ( he's been doing the company cars where I work for a long time).
Now after the chain was done I heard that the oil was never changed since I bought it because it was full of jelly and that doesn't happen in 15k km that I did with it.
And after the chain was done the ticking noise kinda got out on the surface and now I am in the middle of this mess looking for a feasible way out.
The guys who did the chain, started hearing the noise louder and checked the bearings, and after that was done, they kinda figured it out, probably by excluding everything else, that is the crankshaft, and they know a guy, who knows a guy and prepare to invest more money...
I'm developing some trust issues because I can't find a mechanic I can trust around here.
Thank you for reading my rant,
Would really appreciate any ideas from a more experienced guys.
🙏
At nearly 10 years old and about 161K in real miles with few or no oil changes to the point where the oil is like jelly, the engine is shot. Actually amazing that it runs at all. Many Hyundai engines self-destruct even when maintained, let alone when abused.
If the bottom end of the engine (crank & bearings) is damaged (likely in that scenario) you need to stop putting more money into that engine and either sell the vehicle off as a parts car or mechanic's special, or have a replacement engine installed - then get rid of it while it's still running OK.
If possible please post a youtube video demonstrating the noise and provide a link to it here.
@chucktobias thank you Chuck for your response. The engine was serviced regularly based on the book until 180k km, after they changed the previous owner did a full service with a mechanic that didn't bother to stamp the book, it's pretty common in Ireland from what I'm seeing. To lower my chances of failure after I saw it myself in that garage, went with a mechanic that I thought he knew what he's doing and had a look and left the car with him to do the full service, now the other guys that changed the chain said that he didn't even bothered to change the oil, just filters. And after 2 days when to see what's up and they showed me the bearings that were on this car( I'll attach a picture) and that probably because of one of them is that noise louder, from my understanding when you open up the engine even for a chain change the other problems come at the surface. After the bearings changed, the noise didn't get any better and I could see that those guys didn't have a clue on what's happening, because after they started saying that crankshaft is half a mm smaller but at the same time they didn't show me any metallic remains in the oil that they changed. Now you have the full story. You can probably understand what I'm trying to do here, I want a second opinion before going doing something stupid, some other guys said that the jelly was in the engine because that garage put some chemicals in the oil to make it quieter, others said like you, stop spending money for this engine and get a SH one, I looking for that as well. Thanks again

@craig21 That sounds really bad. I really think it's too late for that engine. Even the maintenance schedule you've filled in for us is way too long to go without oil changes. The best bet will be to try finding a good used engine, with a warranty, that doesn't have too many miles on it. (If the car has an automatic transmission you can bet that has not been maintained either. Even a manual transmission should have had at least a couple of oil changes by now to avoid excess wear.) The trouble is you need to find an honest mechanic that knows what he's doing to perform the engine swap.
