To op - sorry to see this.

************************************************** *******

So was this just a coincidence or did the engine hydrolock/backfire from excess fuel?

Mine hydrolocked from methanol accumulation in the cold side pipes to throttlebody, but sounded exactly the same on startup when it knocked a rod thru the side of the block (#8).

I didn't continue to try to start it however, creating more carnage. But, still ruined the cam. Heads are ok.

I'm not exactly sure how to check for hrydrolock, to definitively tell if that is what it is...

I will say, that if it was coincidence. It would have to be equal to getting struck by lightning. This thing ran fantastic, until I swapped fuel rails. And only idled for close to 20 seconds.

I know what it feels like, though.

A $26.50 pressure check valve would have stopped mine from hydrolocking.

I think it was running fine as you say, but had a piston that was on borrowed time(cracked, etc.) for whatever reason.

Yeah. It was running great. Had a small drip from the fuel rail on the pressure valve. That's it. 36,000 miles.....

Anybody know what someone will pay for a '10 SS with 36,xxx and no engine? It's a 2SS RS, auto. I am considering selling it for what I still owe and starting over. But, I will lose ALL the equity put in (about the price of a stroker long block). What would you do?

Make the decision that it will be a keeper or NOT. That's what I decided with my 98 Z28 - owned since new and now twenty years old. Yes I recently hydrolocked the stock engine too and replaced it with a TSP LQ9 built for boost long block.

Losing all of your equity is the same dollar wise as a new crate engine or good low mile used engine with some cash left over. That said - equity and cash aren't the same.

Equity turns into cash, however, when you trade or upgrade and then lose it with taxes, insurance, payments, or by drawing down a savings account. It my town, it costs $400 just to walk in and buy a car - stealerdealership fee.

Ultimately, it's your decision. There are pros and cons whatever you do.
