I travel for work so I haven't been home to tear the engine down. I will be going through this engine throughly. I also need to replace at least two pistons. The one in the pic and then cylinder 1 had a part of the ring land jump over and put three good pops into that pistons. Thanks for the...

Why would 6800 rpm cause that? Are you running a hydraulic roller in your 418?

I am starting to think it was from two weeks before I stopped driving the car. I used a bit more fuel than I had thought and ran out of gas pulling into a gas station. I heard it dying so I killed it but it didn't sound good. Once I filled it ran fine. I have a feeling what I felt was...

My compression ratio was 10.9:1, I was running 94 octane fuel, and the pistons are probe.

I thought detonation but all the pistons look great with no detonation pitting. I will have some investigating to do for sure about why this happened. I was only at 6000 km on this engine.

So I finally decided to see what the hell mess was in my engine. Pulled everything out and pulled off the heads. Found a couple problems. Cylinder six blew a head gasket and cylinder four had a broken piston. The cylinder with that had the broken piston has markings but the head is...

May the force by with you.

I don't think cheapness was the thing that never made me replace it. Just inexperience. That was my first engine build by myself. I am just happy that my crank, heads, and rods are in good shape.

I know....I just don't want to admit it. When I was building the engine I didn't think I would have valve clearance issues but when I the heads on and turned it over by hand I found I didn't have enought clearance. So I had to pull it apart to have the pistons machined. I think I should have...

I still have to find the root cause to this. My friend, who owns an engine shop, said the thing that can make those spiral locks pop out is detonation. I want to make sure something like a spiral lock doesn't crater my second build.

It sucks. But....I like to take a bad situation and make it great. I had a second phase for my build which I was planning for 2013 but I will bump it up now to be done in 2012. Next phase: custom sheetmetal intake with an air to water intercooler, 4L whipple charger, Dart block, and dish...

So at the drag strip I noticed smoke out the back. Ran fine so I thought head gasket but when I pulled the plug to do a compression test the plug was hit. My spiral lock had let go. So my wrist pin was rubbing on my cylinder wall. Not huge damage but the block is no good. I will be...

true dat

It is never an easy out when it is in aluminum. Just get it done by a shop. Live and learn, we have all been down that road before or at least I have. In the future make sure it is clean then use some lubricant. Cheers

If I where you I would pull the plenum off. and use a drill press to drill the bolt out. Since it is aluminum I assume it is to seized to do much else. Drill it to a size that you can tap a bolt size up. Then you may have to drill the other hole to fit the bigger bolt through. That is what I...

The burnout is part of the breakin process for the build. It was the responsible thing to do. :D

Thought you guys may enjoy this video. Did a burnout on a secondary highway close to my acreage. Cheers YouTube - Lucas' Burnout.mp4

Very nice. That turbo looks like it is half the distance in the pic because it is so large. lol I am sure you know already, but very nice power plant you have there.

Do you have a link to a picture of your engine bay?

What did you use as your attempt, and what was its shortfall?
