I have a spun rod bearing do I have to rebuild my engine?

I want to know if I have to rebuild my engine or can I just get away with replacing the bearings and machining the crank? I have a 2003 Celica and I went less than a mile while it was knocking.

what modifications do you recommend if any in rebuilding this engine?

will69gt asked:


2.7L V6 from a Dodge Intrepid 2000 model. I have researched and am aware of this very flawed engine. Yet, still, I am rebuilding this engine. This car was given to me and is in very nice shape, besides the engine needing repair, due to rod spin. I have already removed the engine, tore all apart, block is in machine shop, gonna get a crank kit, 6 rods and piston set, all gaskets and seals, so most likely a master kit. After I get all that done and back, I will be putting the engine back together at my leisure, and take the 2 heads to machine shop for valve job and check. What modifications any has to make this a good engine is appreciated. I do see the oil drains in the 2 heads are very minimal and poor, along with the exhaust ports, catalaytic convertor, all this overcooking the oil. Any particualur type of oil should be used in this engine, or my newly rebuilt engine? Best plugs, and all other best parts?

Does anyone know the steps to rebuilding a bottom end/block? 92 Mazda B2200?

Friday, October 9th, 2009
Chris V asked:


So…My bottom end Is going to hell in my 92 Mazda B2200. This Is not the first Mazda that I’ve had do this to me and I’m sure It won’t be the last.
My trustworthy (expensive) mechanic friend says that It Is “Piston Slap” and that I only have a certain amount of time until my block cracks.

What I would like to know from my viewer’s on here….Is how to rebuild the bottom end.
I know how to the pull the motor and take It apart(with help).

What DO I need to get machined?
What parts (besides gaskets) Do I need to purchase?
Should I do anything aftermarket like a better crank,crankshaft, and so on?
Does the crank and/or crankshaft need to be machine while that Is out?
I have an idea of what I will be doing….Just need a little help getting It all sorted out.
Thanks everyone soooo much for taking the time out to read this.

I have a 350 engine I am rebuilding w/ little/no money- need advice?

Sunday, September 20th, 2009
Steve asked:


I am breaking the motor down completely, and do not anticipate to have any machine work done, except have the cam and crank inspected. I plan to hone cylinders, new rings, possibly new pistons, all bearings, gaskets… not sure what I need to do w/ the heads w/out sending them to the machine shop…
Can someone please send me some pointers in breaking this motor down, and putting it all back together, w/out getting any machine work done?? Thanks!

can you help me guesstimate the cost of rebuilding my 4.3l?

machine rebuilding
Nad _ asked:


Ok my 89 chevy 4.3l is pretty well worn. I’d like to pull it, rejuvenate it and drop it back in. No mods or upgrades, just a standard rebuild on a stock engine.

My plan is:
complete gasket set
all new bearings and rings
new oil pump
new sensors

reuse:
cam
crank
rods
pistons
timing gears / chain
valves
maybe reuse valve springs

and take the heads to a machine shop and have them redo the valve guides and seats.

Assuming my internal parts are fine and I don’t need any machine work other than the heads, can someone give me a ballpark? Would I be saving anything rebuilding myself or should I just use the motor as a core deposit?

Is there anything I am forgetting here?
