About engine heads being changed, I felt it it's necessary for folks here to know if it is true.
Before sharing stuff, let me make an amendment to what I said. Engine head changes have been observed in both AT and MT variants, not just ATs.
Secondly, I made an assumption that many owners would be aware of this. Apparently they aren't. And that is the reason, I feel it's better they are made aware.
This post is not to put people into panic mode, or start a campaign against or malign Tata. It's to make owners aware that such an issue can crop up in any Hexa. Why I say any? Because Tata has no answer as to why it happens. And we would like to know why it happens. And maybe assured that it would be resolved by Tata if it crops up after the warranty is up.
One of the reasons this issue probably hasn't come out in the open is Hexa's low sales figures. Most of the head changes are done quietly with no debates. Hell, one uninformed owner reported this change, photos of invoice in tow, where TASS replaced the head under the guise of 'service campaign'

My last post was shared on Hexa's telegram group by a fellow owner and a discussion was sparked. We wanted to know if this issue is common and what is the cause.
Only a couple hundred members are active in this group. So the numbers I report are from those, not the whole odd 26,000 Hexas sold. Issues are reported in 2017 & 2018 year models. No known issues yet in 2019 makes.
For reasons unknown to us owners and even TASS, a leak is observed between the engine head and exhaust manifold. This is accompanied by a decrease in oil levels and overheating. In some cases, I guess changing the gasket does the job. But most of the owners who reported have undergone an engine head change. Now as it usually is with Tata, the job is done smoothly or with some hiccups for owners under warranty.
1. Currently I am aware of 11 owners, whose Hexas have undergone engine head changes. You can make it 12 by adding BHPian jalsa777's Hexa to it.
2. 1 gasket change. I guess this is done if the issue is found early and head change can be avoided.
3. 2+ owners are now reporting leaks. But nothing further can be concurred unless the lockdown is lifted and TASS opens up.

Here's how it looks
This post is to inform Hexa owners on and off the forum, that this issue exists, and so they won't find themselves on unfamiliar grounds if they face it. The reason I say 'exists' is because there's zero clarification from Tata and hence, it can crop up in any Hexa.
Some owners would find no leak, just a greasy residue in the same location. No need to panic, just clean the area and check after a couple hundred kms are clocked to be safe. Here's a pic from a 2017 XT with 50k on the ODO.
