Headgasket - Well this does not look good Return to Directory

I knew my vehicle was plagued with the headgasket issue due to the model year, and it was only a matter of time. I have been monitoring it closely for years and no mechanics could determine any headgasket leaks, however it was clear to me that I kept having to fill my coolant (very minor fills). I tried to run the 4R around 3k miles each change, and sent my past 4 Oil changes to Blackstone to get tested and just got the latest results.
They are suggesting I do not run the vehicle much longer on these gaskets, however the only sign I have had for years is a very slow loss of coolant, no overheats, no smoke in exhaust etc. For reference I am right about to hit 180k miles (about 300 to go).

I saw a post on this form HERE, that said to go for the engine overhaul kit vs the headgasket kit as it covers all top-end gaskets and is not much more.


The concern I have, is if I were to replace this all myself, what the odds would be of having a warped head or something else go wrong along the way.

However, If I do decide to go to a shop and pay $$$, would a Toyota dealership be ideal due to their warranties?

Looking for some guidance/experience on this.
I am unsure what the costs are for these today, as everything is inflated so anything helps!
