If the bearing(s) seize, you will ventilate the side of the block with a rod or two. Better to park the car now and rebuild...instead of hunting a new block because yours exploded.
Complete removal, dissassembly, cleaning, etc. In other words, an overhaul. Don't take this wrong, but just from your posts I believe this is beyond your current skill level.
do i have to rebuild the whole thing or can i simply replace the bearings somehow? How do i isolate which bearing is bad? cmon' i reallyneed some help here guys.
There may be in your area an adult education auto mechanics class. Maybe become friends with a local mechanic that will show you how things work and has the experience and tools for a rebuild. To remove the main and rod bearings, you must remove and completely disassemble the engine. You might as well complete the rebuild with new pistons/rings, gaskets, timing chain, camshaft, etc. You have to take it all apart anyway...
Well you will get that oil leak fixed while your at it I bet Did ya know it was leaking allot or the typical leak you just didn't check the oil for 6 months?
Dude, don't beat yourself up over this. We've all been there, me included. I did the same thing, only to the engine in my GSX Prototype. Don't think I wasn't pissed off? I was, but rebuilt the engine better and stronger than before with the help of a friendly local mechanic that took me under his wing. Life's lessons... I just have probably 30 years experience on you. You'll survive, I promise.:beers2:
Brad, I am assuming the same..... KE6BOU here... Nice night here before the rain tomorrow. Time to run the GS.. Thanks
Yea, we're suppose to get a chance of snow Tuesday, love Ohio weather. BTW, fix your VIN in your signature...you're missing 1 digit. 73 de KG8S
im meeting up with a fellow 340-er tomorrow to see if he can give me some advice. is the dissassebly and assembly the same as a 350 sbc? i know the parts and specs are different. but im thinking i can take it out and apart then to a machine shop to have the heads re-done and the honing then i can put it back together???
I starved my engine of oil when I ran it on a chassis dyno last year just before the BPG nats. We were in a hurry, and it was about to rain. We had to push out a couple $50k Cobras out of the garage to run my car. This was after a long drive to Cincinnati from St. Louis...so there was some oil consumption to be expected, but my head wasn't in the right place that morning. The shop guy revved it to 5500 rpm, and it spun 2 bearings. Later, I found out I only had about 3 quarts of oil in the pan. It got sucked dry. It ate my crank and destroyed the oil pump pocket with bearing material.
The basics are the same but you're right on about clearances and such. A Buick should NOT be set up clearance wise by a person with only SBC experience. Clearances will be much too loose.
i have the specs in a factory shop manual but im sure itll still be too confussing. thanks again guys looks like im not driving her. since it ony happened last week im praying the damage is not that bad
if i did decide to drive it or someone had to borrow my daily car. what risks am i running? worst case scenarios?
Best case scenario is you'll only ruin the crank. More than likely you will seize a rod bearing and the rod will break, thus putting a rather large hole in the side of the engine. Don't do it.
You can take it apart with little problem over stuck or frozen bolts. Just be careful to mark where everything went, tape n mark every part what it is and where it came out of, make drawings, bag some, push bolts into cardboard to keep location or order. Over detail that part so anyone could put every part, bolt, nut, screw or what ever right back where it came from. Get pro to semi pro help for assembly, gonna need some proper tools and knowledge on it.
