ARGHHH, I hate when that Happens :( I remember one time cruising around at 5,000 and hearing the GKKK, KKKKGNG, GGGGRRKKK and coming to an Abrupt stop, looked over the side and saw the Bilge Pump pumping out this Red Sh*t...I'm thinking what the heck is that??? Well it's the 2 Gallons of Amsoil Synthetic... Very Sad Feeling :( I Feel Your Pain

PS... That cap does look like it burnt before it let go, Your diagnosis seems spot on....

Well you seem pretty happy with these results lol. Sorry to hear man that's always a bummer.

What were you running for rod bolts?

Doesn't sound like ARP

and rods ?

'H Beams' in of themselves mean nothing to me.

Tough luck, but great attitude!!

Over the years of boating you realize they are time bombs, I am nowhere close to easy on my boat, I am always over 4500 lol so fun! until now...

At least with that window in the oil pan you didn't have to wait until you broke it down before you found out.
Feel your pain.
