Blew It The F**K UP!!!

IIRC this block was bored .030" over right? I am very interested to find out what happened in there, hoping that the same fate doesn't await mine because of the rebuild. I went out and started it today for the first time this month, still starts up great but my $15 starter is not disengaging. I'm interested in seeing more pics as they become available.

No it was stock bore

Shitty, shitty deal Dave :( I hope you fix it, trust me in that you'll regret it if you don't...

Dave,

Sorry about the misfortune, at least nobody was hurt.

I hope you decide to keep it, and rebuild it.

Dave I'm sorry bout the Cutty....but what are we looking at in the pic? I have no clue lol :icon_rolleyes:

Pic is where the starter should be, you can see the flywheel in the hole with the teeth.

that silver circle is a wrist pin that goes through the center of the piston on the connnecting rod.........as you can see there in no piston attatched at this time.

Hijack away......not much left for me to add to this

change the title to

BUY KENNYS MOTORS OR THIS WILL HAPPEN!!!!!

hahahahah
Hey now, I said IBmoredestruction..... :icon_razz:
A.K.A I'm waiting to see how bad it looks inside, poor little engine :( When these things blow up, they really seem to blow up, they don't just bend a valve or anything, they like nuke pistons, throw rods, etc. etc, Wrist pin sticking out the Oil-Pan.....damn..... :icon_eek: The cousin's 383 just blew up, all it did was burnt a piston/broke a piston skirt, these little guys like make interesting artifacts when they go :laugh:

The Ticking Timebomb finally reached 0 I guess :icon_neutral:

And I thought I was the master of distruction.

I consider this little engine pretty strong. I have melted two or three pistons and bent a rod pretty bad, wiped out two cams and it never
came apart.

Dave's was defiantly not old age. Sounds like something was put topgether wrong or something in the machine work wasn't done to size. He defiantly lost a rod, but what caused it?

I had a crank ground which was ground so off center that i didn't use it (oil groves on each side were ground into with the back side near stock) and bought a reground that was perfect. This is not the eaiest crank to gorind. It has to be centered perfectly and what ever is taken off the journal should be removed from the oil relief grove on each side of the crank journal.

No telling what caused the distruction but I am sure Dave will let us know.

Can't wait Dave.

I had my bottom end done by a local friends shop here in town and he is gonna take a look also and see the cause.

thats the only thing i never did on the engine myself was the bottom.....so im not blaming myself yet

sleeperred90tgp · October 23, 2006, 07:48:27 PM

Yea don't blame yourself yet. I think your plenty mechanical to put an engine together. (did you plastigauge a couple of places?)Don't know if you had your crank ground but thats a critical area. If you had the rods resized thats another critical area. If the rods were put on backwards doesn't make alot of difference unless the pistons got turned around and as long as you put the arrow to the front, don't think that would have been a problem.

Invasion1 · October 23, 2006, 07:53:01 PM

No Jud i got the bottom end all assembled and all i did was put the oil pan on and put the heads on......the place where my friend works has done a few engines for me in the past.

350 chevy for my old 1980 Pickup
3.1 which was the original engine in the 1992 CS when it broke a head bolt and flooded the oil with coolant.
and several small engine motor work that requires machine shop equiptment.

we will see when i get that block out and open the pan

I would first go with a broken timing chain or something that caused a valve to hang/stay shut and the boom didn't have anywhere to go, or a spun bearing so no oil and it went boom boom....

i had a timing chain break on my Turbo 3.1 and all that happend was 3 of the valves just slightly nicked the piston tops. replaced the timing chain set and still runs great to this day.

i drove the STE around for a week without an exhaust cam lobe.. imagine forcing the exhaust gases out the intake valve against 9ish psi. i doubt that scenario would've caused his boomage.

Invasion1 · October 23, 2006, 09:16:40 PM

Well in the meantime im car shopping, i needed a new winter beater to replace the 1990 CS that died last spring.

dunno what im gonna get though.

z284pwr · October 23, 2006, 10:01:44 PM

Apparently everyone has had different experiences there too, last timing chain failure I saw took at all the valves, and the engine could be turn over by hand by spining the alternator fan........

What price range you looking for Dave? To bad you can't just drive you new snow cruiser as your winter "beater" :laugh:
