Hi,
I'm currently in the market for mazda 6, I've been reading up on quite a few cases of cylinder head crack, at first I thought it was only for 2.5T's , however there's people saying they have head cracks (in different spots than 2.5T's I believe) on 2.5NA's too. Some say it's because of cylinder deactivation, others say it's a defect from a factory for over-torquing exhaust manifold bolts and so on.
I'll be buying it from US and importing it to europe (it's cheaper that way + I get lower milage car). Therefore if any issue arises with cylinder head crack, I for sure won't be able to ask mazda for help.
I'm looking specifically for 2.5NA (Since for 2.5T 2018-2021 is TSB for cylinder head crack and 2021 has another TSB for valve stems, ugh...), so I'm wondering if anyone knows, which year would be the best to buy, are those cracked heads on 2.5NA frequent or unicorn cases, perhaps mazda fixed it for 2.5NA something for 2021 year as well? (Like they did with 2.5T in that TSB).
Basically should I be worried or just grab any 2.5NA? if no, which year (2018-2021) is best for 6's?
Thank you!
