Almost as soon as I started my engine up a couple months ago it had a slight tick that sounded like it was in the bottom end. I had 60# of oil pressure and it ran like a champ, so after as much external diagnosis I could do, I assumed it was a pal nut or rod just touching the oil pan since I used the old style 232 pan when I rebuilt the motor. I figured if that is what it is it will not get any worse and maybe even wear itself down enough to stop.
NOPE. I have been driving it and driving it hard for close about a month and a half now, everyday. I have ran 3 tanks of gas thru it and I have a 22 gal tank. I would say maybe close to 1000 miles since I got it together.
Friday night I was on my way home from Temecula {20+ miles away} and doing about 60+ on the freeway { it is running so well I have even started driving it on the freeway when I have to} and all of a sudden this really bad clatter starts up. I thought it sounded like sheetmetal clattering. I looked at everything I could see in the dark and could not determine what it was. I limped it home and it seemed to run fine other than the clatter.
Warren came over monday and we ran it around the block and even he could not get a fix on what it was. He thought maybe front trans bearing, but it did it even when the clutch was disengaged, so i didn't think that was it. Warren convinced me to try and pull the pan while the motor was in the truck and take a look.....here we are today.
I finally had the time to pull the pan today, what a pain, and I see a piece of what looks like sheet metal sticking out fron between the #1 rod and the front counterweight of the crank...not sheet metal. There was NO bearing left on the rod cap, it was pounded into a paper thin sheet of metal and squeezed out of the rod.
It looks like it cooked the crank as well. There is a LARGE ridge between the #1& #2 rod and it feels like it is worn too far to have turned.
Anyone happen to have a good 289 crank and 2 rods?
What could have caused this?
I was VERY meticulous at cleaning out every galley and oil port in the crank and the block {or at least I THOUGHT I did} and I was very thorough at measuring everything and once they measure in spec I even plastigauged all of the bearing to make once last check that everything was good.
It all checked out GREAT. I was very happy.
I am worried now that if I do a crank and new rods and bearings that it could happen again if there is a clog in a galley somewhere I could not find....HELP.
Thanks in advance
