they were the stock bolts, they did not come with washers and I looked online and it looks like none do.
they were the stock bolts from the looks of it, 10mm nut. 23mm length sounds right.
The left side front bolt was the culprit. I saw the hole it put into the wire loom, there are two connectors that plug in, then wrap backwards towards the front, it was right at that bend, it some how pinched the loom against the side in there and punched through.
It obviously grounded/shorted a wire, I'm thinking an injector and it was stuck open.
I'm not gonna sleep tonight
just praying I didn't damage anything. thinking it was a fouled plug I drove it like that for about 1000 yards. stalling every time I came to idle.
It feels normal again and is no longer blowing any smoke, so hopefully I dodged a major issue. I just put in fresh 10/40 mobile 1 oil too, not sure if I should dump it, like I said I smell some fuel in the case from the fill cap, but it could just be from dripping from the header gasket area and getting on everything.
I'll take pics this weekend for shits, before I repair it. Gonna get some liquid electrical tape.
