Digging in "big time" into my Hyundai this week

[Mainia]

2018 Hyundai Kona 1.6T AWD tuner car ( look at my signature link below) 76,000 HARD miles. Hyundai put in mechanical lifters in the 1.6T JUST because they are CHEAP, they say performance engine HA HA. GTI and Golf R have hydraulic lifters. Enough said. They spec to check at 60,000 some have seen a need to adjust at this point too. I also want to stick in some ARP head studs and dump the OEM head bolts that are known to stretch. One for one replacement, to keep the head gasket seal, I hope. I also want to replace the high pressure fuel pump roller cam as a preventative maintenance issue. I have seen a couple rollers go bad in industrial equipment that is in my head. Cams must come out for all of these R&R. If so I will also be changing the timing chain/guides /tensioner since it is of course, CHEAP and not that robust, because I am this far.

ALL OEM parts from an online Hyundai discount parts from a known USA Hyundai dealership. Avg 20% off. I even bought a front chain cover $112 to reduce a chance of seeing Mr Murphy, worth the piece of mind. First thing is to document valve lash cold, then once the cams are out mic the cups with a new Brown & Sharpe mic as the laser etching specs are not suppose to be used because of cup wear. Once I have the new cup specs needed it is off hopefully on Monday/Tuesday to the local dealer for a next day delivery order, for all new correct speced lifter cups. Fun Fun!!!!

The 3.3 gdi also comes with mechanical lifters. Never was too happy about that.

Waiting on parts. Some valves at low limit, so I shooting for mid speced spread. 12 out 16 are getting new mechanical cups. Also going with new cam phasers too, some wear on sprockets. Should take 2-3 days for parts, lets see if my next day air fee of $170 is worth it. They most likely wont have all the parts thoughso hence 2-3 days vs 1 week.

Wow ! For a 2018 with low miles? Wow $??? I thought Hyundai's were supposed to be low maintenance, unlike the German cars?
Most of them don't need all this kinda work because if the engine goes poof, they will replace them for free.

Impressive work and ambition, but dang, what sort of tune are we talking about here to require such drastic preventative measures?

They won't replace mine. I voided that warranty long ago. ( see the parts list in my signature link, they saw all that stuff when I had them put my cryoed clutch in) The only warranty I received was a $2,500 dual clutch actuator that they screwed up after the clutch install, by leaving the adj. plugs open in Minnesota winter/spring slushy roads. Can you imagine trying to fight that one if the warranty was not there. The order writer slipped up telling me about the adj. plugs were flipped open. You know Hyundai's are high maintenance, one of the top cars out there jamming rings. Hyundai spec to check the valves at 60,000 mile.

First off, do you get my comment on the mechanical lifters? I was saying Hyundai said it was a performance engine, is why they used the high maintenance mechanical lifters, which I laugh at, as it is not. YET a Golf R actually is somewhat one and they have zero issues putting in hydraulic lifters. Hyundai being cheapskates is all that is. I paid $8 per lifter cup my price. Hydraulic lifter......what $50-100 ea??? They start seeing burnt valves at 100,000 to 140,000 miles. I am doing it now that I am working and have the money that I won't have it like I do now. Of course it's a Hyundai, as long as the engine Gods hold it together. The timing chain is the size of a bicycle chain. Is it stretched ??? ( I am going out to compare old and new) ............ 4.5mm stretched, not bad. Cam phasers, did they need to be replaced for the average person NO. For $220 for both OEM phaser, both chain guides total $24, timing chain $49 heck yeah. I forgot to add too, it doesn't hurt to get a new oil pump "for a Hyundai" that comes in the cam chain cover.

A good half of all the Hyundai/Kia tanked engines I think are complete lack of maintenance, as they replaced engines for oil use, when it is just a jammed ring issue if caught early. I just can't believe my engine is still around to do this after a massive LSPI event when new, then add the thrashing and Stage 2 tune. I want to track it, at BIR, but I already blow up a car up there at a Porsche Club Invitational in my early years and took a first place in my slot, when I had 2 cars up there. The Hyundai would not make it. Surly not setup with bad cooling of engine/engine oil cooling.
