this is not one of them.





this is a picture of my oil pan from the old 305 I took out last week.



This is the rotating assembly. I removed the 3 & 4 pistons/rods. Well, actually I removed the #3, the #4 kinda fell out considering the other half of the rod was in the oil pan. Number 3 was only twisted and bent a little bit, with a broken piston skirt. Also, the #6 rod snapped in the middle. There are two missing main bolts- I have no clue where the hell they went. There are chunks missing out of the block in the center of it.

I'm still in shock how badly I destroyed a "bulletproof" 305 like this. I believe I have traced my steps back to the week before Christmas 2004. I posted a thread here about my coolant being frozen. I was running a summer mix of 70/30 water to coolant, which was to freeze at 5 degrees. It was easilly -5 that day here in Michigan. I drove about 5 miles to the mall, and on the way I realized that my heater hadn't even gotten warm yet, even though the temp guage was reading about 220. By the time I got to the mall, it was in the red.

My belief is that this heat burned off the addatives in the oil (which was 10w40, and about 1k old) causing it to turn into a disgusting thick sludge. I was going to change my oil later that week, with 5w30 due to the rapid freezing temps that came that season. I wasn't prepared for the chill that we got, and I was originally running 10w40 to slow my rear main seal leak (to no avail). If anyone knows how multiweight oils work, they would understand fully.

So later that day, my engine was making slight knocking noises and I quickly dismissed it as a loose rocker arm. I also noted my oil pressure acting funny, going up and down sporatically. Magically adding an extra two quarts of oil solved that guage problem, but the noise was still there. I tightened all of my rockers about 1/8 of a turn on the passenger side (because that's where the noise was coming from). Nothing really helped. The noise increased in intensity for two more weeks.

I was driving to work, January 7th, about 2:45pm. Highway, I-94 westbound into Ann Arbor. Fast lane, 80mph, 2000 rpm... BAM!!! car shuts off and I coast to the right shoulder and immediately start laughing. Car won't even attempt to turn over. I call my dad, get a tow truck, and take it home.

Long story short, a picture will tell you a thousand words.

As bad as that sucks, I've really got nothing else to do than laugh pretty hard... that's one beat up 305!

I was going to kid you about the 2 missing main bolts thinking you took them out, but when you said they were missing my face goes " " lol.


I had a similar experience with my "bulletproof 305"... My first tune-up I had changed plugs/wires/cap/rotor/O2 sensor, and while I did the O2 sensor my friend put the plugs in... well, I saw him with the spark plug gapper, and so I assumed he was gapping them, right? Well, we get it all buttoned up, I start it up, it's pinging like mad, we cant figure out what's wrong...

I ended up calling my uncle, he comes over, starts the car and revs it to about 4k in park with it pinging the whole time, and says "it's a broken flexplate" and left. I pulled the flexplate cover, flexplate was fully intact, uncle's a dumbass (like I expected)... so next morning I went out and got new spark plugs and did them myself... come to find out, my friend had just made sure that the gap was the same on all the plugs, not actually gapping them to spec...

so... the revving consistently to 4k by my uncle in park with mad pingage loosened the bearing clearance enough.

Then about 2 months later my starter crapped out on me, the whole solenoid cracked in half, when I got it started again the car ran like horse crap. I didnt know why, figured a vacuum line was loose or something, figured I'd fix it later... then about a month later I was driving a car full of my friends down, we stopped at a place, went back into the car, I started it up and oil pressure light just stayed lit up.



What I figure is that the engine had a "minor sieze up" (if there's a such thing) which caused the starter to crank so hard that it broke the solenoid, but that was just a temporary fix to the motor problems... the rough running was the knock sensor going crazy, then the oil light staying on was the car saying "enough abuse!!!!!"



Arent those 305's just so pretty when they're TOASTED? lol

without broken 305s, people would not have hopped up 350s
speaking of siezed, my #6 piston WON'T BUDGE! The wrist pin is siezed up otherwise I would have removed it. I have yet to try the BFH on it, but haha at that.



AND SERIOUSLY WHERE THE HELL DID THOSE TWO MAIN BOLTS GO??? I didn't really notice they were gone until I was browsing the pics. I didn't remove them, and if I did I don't see why I would.

That particular main cap looks permanently attached.....nevermind....haha I am tired and saw wrong.

Engine looks like it could go another 100,000 miles

I have pics like that when I blew up my 383 back in 2001. I had a lot more parts sitting in the bottom though. 2 of the cylinders didn't have pistons in them. I also had some lifters and pushrods in the bottom.

that engine could still probably rape mine....

you still have more working cylinders then both my cars put together

STOP PLAYING NASCAR TILL 6 IN THE MORNING

my old 305 had similar damage to it, good work token LOL

holy crap!

I hope thats not what the inside of my oil pan looks like, allthough im expecting simliar results. 2nd sbc that ive fried in my history of owning 3 cars >.<

Im currently in the process of ripping out the motor, im lazy and its taking some time.
