Thanks Paul, i'm kinda satisfied with your explanations on the piston and valve. Again back to the cylinder head, was it possible to have one upper side to be damaged? (Refer to my case), As you described, "When this kind of situation occurs it may be in one, two, three or four of the cylinders. The head that I showed was an extreme situation, thus why I saved it. More typical is one or two cylinders that get damaged and usually the valves only bend not snap. It was so extrodinary it was worth documenting. "
So, i'm just curious on how the badly piston can cause the one side cylinder head damaged. I assumed that it must damage all rounded in the cylinder head face. But it won't, right? THAT'S question didn't really answer and I wanted to have the wider opinion among your colleagues.
YES, techs are paid on labor but telling you the truth, in Malaysia this don't really applied to most of the techs. They tends to mark up the prices and then be able to get their own profits out of it. Not to give bad interpretation of Malaysian techs but they are most likely to do that.
I suspect they change my cylinder head with another car because during that time there was one case that has similar situation and it might happened.
The truth is, I did filed the case to the consumer court and will be hearing on the coming 1st October. I want to win this case and had them pay for me. Unfortunately, as an expert you are not on my side and I have to be ready to face any consequences.
The motivation he had to do that is for the profits margin.
The curiosity of his sincerity would be these
1. He did asked me that time, was it me really know about an engine? My answer was definitely, I don't know anything about that.
2. I asked him to show me where was the damage, he refused to do that until I towed it back without any repairs.
3. I asked him why I can have the pics that he captured at the first stage of opening the engine. He said, that pics was for company goods and it was confidential.
4. I asked him how he tested the cylinder head? Any report or techical expalantion? He didn't really show his professional attitude where he just mentioned that the other workshop had an agreement with that the cylinder was faulted.
5. He took a week to revealed the cylinder head problem. In facts the quotation was too shocked. RM10,000.00 about U.S2940.00 to repair the whole engine. It was unbelieveable here in Malaysia.
My question to you:
Between cylinder head and piston, which one on the top of its configuration? If the cylinder head on the top, the cylinder head must be opened and clearly reveals the damages right?
BUT in my situation, at the first day he showed to me the piston, why he didn't shows the cylinder head? He said that he had to test the cylinder head first, if he was very sincere, he must show to me the damaged area then I can trusted him. It didn't really happened that time, after 2 days he just mentioned cylinder head fault but didn't show the damages. I suspected him hiding something. I'm not satisfied then I towed it to the other workshop and they revealed to me damaged cylinder head. How should I trust him?
Paul, I need some other opinions on this matter. Thank you. I appreciate it.
