A bit of an interesting couple of days past, but here goes.
The pictures for Curious Chris' 12,000 mile head with FOD (foreign object damage). You have already seen most of these Chris. I know you are putting this on me, but the cylinder head tells the story.
This picture shows a dent in the center of the initial damage. The intake valve was sheared off in a single piece, which then shattered into several smaller pieces. The deep dent could not be caused by the valve material itself and it also had a cylindrical shape. The subsequent damage of pieces of valve seat striking the cylinder head and valve show much less denting as the FOD. There are many other impacts that you can judge are the FOD making it's dents before exiting. No object was noted or found upon disassembly.
The shape and size of the FOD are clearly visible, as shown in the following pics.
These two pictures show the depth of the impact and the distance of a single piece broken off of the valve's seat area.
This last picture shows the FOD damage on the intake valve near the 2:30 position. The impact crossed both the valve and the bottom of the cylinder head. I don't know what the foreign object is, but I believe it is not any VW part or piece.
So, Chris, to finish this story, I was told I 'made a bad cylinder head' and you wanted something of value in exchange for it; a turbo as I remember. In warranty disputes, I always have done the same thing. I send a pre-paid UPS shipping label and examine the part. I don't recall the exact date I sent the label, but it was months before the cylinder head was returned. I admit, same as with Bryan, I have been swamped, but when you prompted me, I got the cylinder heads, the original one, that had valve leakage, and this one, which was destroyed, and did my analysis.
I did find the original head had a valve that was spinning out of round. I vacuum test heads, so I don't know If I missed it or not. I will not debate that, but then Nick showed up over a year ago, about 2 weeks after my wreck and picked up this replacement head. I am guessing it was about the third week of October, 2017. Then, I believe it was about 7/2018, I got the report the cylinder head destroyed itself and you wanted compensation. I made the label and then started waiting for stuff to show up. The cylinder head showed up in November, 2018.
If I had not seen the cylinder head, which you seemingly thought was not needed to be sent, I would not have found the FOD damage. All claims for warranty must follow protocol. I have the right to inspect the damaged item before determining validity of the claim. In this case, I find abuse by foreign object.
But I am sure you still want to lay the blame on me.
In all of the cylinder heads I have made, and people know, it's thousands, I have few failures. Admittedly, there have been some. Overall, people also know we back our product, but do not cover abuse.
Sorry, Chris. I would have liked to work with you, but I will not accept your claim. I am not, nor have I ever blamed (Nick, Greengeeker) for the cause of this damage. I have no way of knowing how the damage occurred,
It is not reasonable, as you claim, that a foreign body stuck in the head from the time I built it, only to fall out after at least 6 months and 12,000 miles.
