It is very little mileage for an adjustment and more on top of a crankshaft ... also you bought it, therefore, therefore the damage comes from an earlier treatment, but if it is a trailblazer, which should have a engine for much more mileage than you hard ...

Anyway, the decision is yours, but if it were my case ... step ..

I just changed rings and metals of my silverado, just because I was running oil for several seals, take advantage of getting engine and maintaining it, without any rectification on top, the truck has 430 thousand kms and I have it from 60 thousand

Well, my situation, my mechanic told me that this failure was because I do not pump oil for dirt probably by cochambre accumulation (I do not know if I explain) that accumulates due to lack of maintenance, in short
you thank you very much your timeempo and I will take into account your advice
thanks again Miguel Brito Ruiz

Hello friend regarding your doubt as you mention, work perfectly well only that you should tell your mechanic to verify the oil pump to make sure that it is not scratch or otherwise replace it if everything is fine, arm it that to that measure works well and you must be nest to the oil changes so that the same does not happen to you again

The rectifications of crankshaft and expired are common, they are well made and the vehicles agunatn a lot more than kilometers just be careful with the oil issue, if I am perfect I recommend you to keep it you will have no problems, the crankshafts can even be filled to give factory measures is not the end of the world. I have restored some old vehicles of which there are no longer spare parts and I have made that type of repair and all good.
