Charlie_Brown.... I've been following this thread but have avoided a reply due to the fact that I retired before that engine came into existence, coupled with the fact that it is (I believe) a 60° V/6 (Carbs on the side of the powerhead instead of in front) of which I have no working knowledge of.<br /><br />However, in my years of experience, nothing could really be determined one way or the other pertaining to whether a failure took place due to a engine component malfunctioned, operator neglect, or if it was caused by an accidental encounter with a foreign object.<br /><br />**********<br /><br />There would need to be an agreement with the insurance company (in writing) which would stipulate their consent to have the engine torn down in order to determine the extent of the damage and the exact cause of it. You would want a very qualified technician/mechanic (yours, not theirs) to handle the dismantlement of the engine, and you would want percise notes of what is found along with photos of the engine in various states of being dismantled.<br /><br />**********<br /><br />Leave nothing to chance in dealing with a insurance company. Had a house fall in a hole due to (unknown to us) being built on a small landfill. It didn't fall due to a sinkhole. Insurance company said Tough Beans... lost $80,000. Gives you a good idea as to what I think of insurance companies.<br /><br />Now, I understand that fuel is spraying out both sides of the block. Assuming that you've checked and have found that this fuel spray is not being sprayed out from the fuel lines or the carburetors. Frankly, I would find that scenario very unlikely due to the fact that the identical problem exists on both sides of the powerhead.<br /><br />Sooooo this fuel spray would either have to be coming from a cracked powerhead, or the GelSeal at that one particular area suddenly decided to fail for some unknown reason. Of course I'm not there to view it but I'm inclined to go with the cracked block (crankcase) scenario.<br /><br />Now, blocks (easier to type than crankcase) do not crack from the outside inwards unless they are hit with a hard object with a great amount of force, and this would need to be hit in that manner at least twice... not likely.<br /><br />This leaves the scenario that the block in those areas were hit from the inside. Unless a connecting rod was torn loose which could do that damage, I can think of only one other way that scenario could take place, and that would be that the crankshaft broke in that area which would let everything connected to it go off center. The flaw to that thought though is that the engine shouldn't run properly (fire on all six cylinders) after that. But, as far as I'm concerned, my thinking (at the moment) is that something hit the interior of the block in that area due to the shock the engine encountered.<br /><br />Clanton brought up a good point about the exhaust housing being out of line, bent. Unfortunately the only way to check that is to remove and dismantle it completely, then have it setting on a perfectly flat surface. Using a percentage dial indicator, the distance is then to be checked from that flat surface (close to the housing) to the top surface, all the way around that top surface. If it varies by more than 10°, it is not usable and must be replaced.<br /><br />Hopefully, at some portion of this rambling, there has been something worthwhile said. I wish you luck.
