No we did not blow Adies engine.
The sub standard head gasket solution (two head gaskets and a non-conformable decompression plate) that was implemented by whoever built the engine, failed catastrophically.
Upon inspection, other internal isses were discovered that would have significantly reduced the engine's life expectancy, even if the sub standard head gasket solution had prevailed.
As with all situations where there may be a suspicion over the quality of our work, I recommended that Adie obtain an independant Engineers report. He did that, and I guess it's up to him whether he wants to share that with you but I can tell you that there was no fault found with our work.
That's correct. The head gasket failure was the original symptom and cause of the failure.
Upon engine strip down and inspection it was discovered that the piston skirts had seized in the bores and that there was a significant amount of dirt and debris inside the engine. Aparantly the engine had previously experienced a recent oil pump failure so I guess it is possible that the engine was not cleaned properly at the time of the build or subsequently after the oil pump failure (this is purely a logical speculation based on the discoverable evidence, and is no way intended to be pejoritive towards the engine builder).
Of crucial significance is the fact that there was no damage to the piston crowns. If there was damage to the piston crowns this could have meant that our tuning proceedures were not correct and possibly the cause of the engine failure. A classic symptom of incorrectly calibrated fuel and/or ignition is what is known as "detonation marks". Detonation marks are demonstrated by clear and obvious severe erotion damage to the piston crowns and cylinder head. Adies pistons had no detonation damage whatsover as confirmed by the independant Engineer.
The reason Adie had to change the pistons was due to the scuff marks left by the partial seizures, and not related in way shape or form to any tuning work that we had carried out.
The head gasket failed during road testing, therefore no dyno data was being captured at that point. Chanjit was offered the hard copy of his calibration report.
I am hopeful that you and your chums have a better understanding of the situation now, and now realise that you have been completely wrong for a long time which has resulted in a high degree of toxicity for LOC and TDI.
I don't expect an apology, but I will request that you try to avoid jumping to conclusions in future. All you need to do is ask to find the correct answers.
All the best :)
The hard copy being some hand written notes.
