Found the noise in my engine

Ya, I probably get too involved for most folks believings, after all how the hell can you with so many miles between. Well believe me, it's possible with technology. I've worked all but first hand on his projects and he has mine. We watch through video and listen from.... Sucks though, throwing wrenches through the screen. No worries of being knocked out from all the cursing and fighting. But, internet regularly goes down. lol Yes, very good friends if I can say so myself. A project like this and the way it turned out was very taxing, it's a relief to spill the facts to say the least. We are all lucky Mick has someone to help post, he'd otherwise be on some other project we would not be aware. Are we really ready for the Australians interpretation of the hole mess? I'd really like to see his future work so it still could be a good thing to be involved.
Way more Micks out there, someone just needs to convince them to post. hehe.
And yes, we like superchargers.
Has it been that long?
Thanks Chris.

I've read this entire thread and the links, all I can say is damn, if you didn't have bad luck you wouldn't have any at all. I have a few questions. First though I have to salute both Mick and Mika in Finland for doing what they do and being patent enough to wait and pay the sky high prices they have to pay to build their dmax's.
The builder if I'm not mistaken is considered one of the best in the country when it comes to building dmax engines isn't that correct? He built Nasty Girl's engine, and also the Mormon Missile correct? While I don't know that much about what the original spec were suppose to be, I can't believe the compression ratios were even close to what was called for right from the get go. I'm assuming this was not the builders first dmax engine build? Has there been others who have had the same problem? I know when I had my two engines built the builder didn't warranty them, but not because if his build, because what we were going to do to them pushing them to the limit. When we thought we had a problem with the one engine from the get go he was Johnny on the spot trying to help. Turns out we had a defective injector cup, so no biggie.
The builder at a minimum should totally reimburse the cost of the build and what it cost to ship to Mick and replace any parts that can't be reused. Could be the entire engine by the looks of it.

So wait, you post for mick??
Sounded like that but no, just help. He'd be banned if he told it like it is. Don't read more into it, We work together for hours a day.

X2. Hats off to these guys, Lennart, and all the others doing these builds overseas and trying new stuff!!:coolspot:
I doubt a refund will happen but a definite attempt to make it better would be what I would expect at the very least. No doubt frustrating. Simon's truck drove us both up the wall and we only had to ship stuff back across the border into the US. I couldn't imagine shipping it to the otherside of the planet!!
The 11.01 Pass made it all worthwhile though!

Think I'd puck! Sorry to be seeing this. If not for seeing with ones own eyes, a mess up that bad from such a reputable builder would be hard to believe. Amazing.
No Pat, I was just saying Mick would say what comes natural and may break a few rules. That's all. Maybe I should be more clear. Sorry folks.
Thank you for clarifying that Chris. :hug: I actually originated from New Zealand where they call me Mike but in Aust they call it Mick
I try not to get too emotional over Money and Material Posessions. Life and Family are where its at. All these other things are only a part of our live. Obviously we have had problems with this engine right from day No 1 and at this stage there has been no positive response about the issues from the engine builder and I cant speak for him. I wrote it off quite a while ago. And as I always like to say when I can - Nobody died. :thumb: All I am doing at this stage is trying to identify the problems and probably learn something out of it. Im not out to Crucify the builder, just doing a factual report on it. I welcome his input and any explanations at any time.
Mike on the other hand is alot more indepth about these things and as he has been an integral part in my projects for more than 2 years now it has a bearing on how he feels about it. He probably is more concerned about it than me and thats because he has put untold hours into it as well as me. No doubt you can all tell he's a bit more emotional about things than me and he's also alot more capable in the technological areas than me (computer tech particularly) and can spend more time on these sites without getting bored than me. But he has turned into a valued friend and I am qiuite happy that he has spent the time that I cant, explaing things and posting pics etc. He knows as much about whats happening with my projects as me. Between us we have tried literally hundreds of combinations with our experimenting, particularly in the supercharging arena. We have some pretty exciting stuff we have learned recently that we are itching to put into practice once we have an engine to put it into. Some of these things fly in the face of theory. Im focusing more on that as time moves on rather than getting too negative on this other one. Truth is sometimes failures like this wear us down a bit but a point comes when you have to turn it around and get up and go again..............But I do appreciate all the support that we have had here on this site and I thank you all and hopefully we can offer more in the future than we have in the past. :thumb:

Look at the first picture, shows how much the piston was contacting the head at idle. Over time, 2000 miles, the knocking got worse. Wrist pin wear and connecting rod wear from thousands of small bangs. As you know, with rpm, connecting rods stretch slightly from the obvious. Also, with such a small original contact, and the piston being able to slap from bore to piston clearance, nothing was noticed on installation. Mick did not install the engine by himself, Heath, heathgu on this board help in installation. Between the two of them had there been too much effort required, one of them would have known. Will know more when the rod bearings and crank are checked as well as wrist pin bore. Just gross measurements with a caliper so far.

Not sure if you're being sarcastic, or just don't know about engines, but for those readers who really don't know:
- Aluminum expands with heat. Quite a bit as far as metals go. Just because something is AOK at room temperature doesn't mean it's AOK at operating temps.
- Pistons rock in their bores. Grab one and check it out. It's a good amount.
- Due to the circular function of a crankshaft rotation, you actually can rotate an engine on a stand that has a small interference. You have incredible leverage available when approaching TDC; this is how some tools work to magnify effort.
That would not be the only Dmax engine that has banged pistons against the head when running, yet was OK on the engine stand. Ask around.
I was thinking that it probably turned just fine before firing and getting warm. Compression had to be way out of wack however.
