Tips and even scolding are accepted

Hello to all the foreros I want to do the following question, my tsuru had just changed my head but I did not ring it clear several friends and acquaintances they told me that I had to ring it because I did not They were wet from oil or water, everything was in perfect condition, and the truth already put me the doubt, because some say that there is no problem and others that yes and then the truth is already where to pull so that I hope they acclal me the doubt thank you very much

In any case, no others are changing rings, but that must be made before diagnosis.
That if you change will have more compression.
The question is that if the pistons collided with the valves ???
And if so, they must first check the status of the pistons, because they could be resentful, and that can work a problem of greater magnitude in the engine.
But if your mechanic says that it is fine and confused 100% in the diagnosis, you should not worry.
But you should see that of the pistons if they were resentful.
Luck

They left a very mild brand but I left the same when carving a little with the finger to check the carbon or nose as the combustion residues that remain in the pistons are called, and it is a mechanic that they recommended a lot

Yes but sometimes they are resentful. Once I passed a friend who cut the run and the valves collided with the pistons.
Change all the valves but not Czech the pistons, at the same time, the pistons broke inside the cylinder and tube that change engine.
That verification that I told you is to avoid those problems.

What
happens is that it is recommended to ring to take advantage of the unarmed head, but when the valves with the pistons do not happen because the valves are very thin and fold easily, if before the chain was burst, the chain was well, the car was not going to worry, I have changed several heads without weighing and not spent anything.
But the mechanic "yes" has the obligation to give you that option of "Anilla to take advantage of the unarmed" luck and
we are here to serve you
