I have a 1996 Buick Regal Custom with a 3800 Series II engine.
It seems that a connecting rod bearing is busted and the engine is making a knocking sound.

Can the engine be removed from the top or do I have to drop the engine and tranny from the bottom.

Appreciate any help.

Oh yes, it can definitely be removed from the top! :)

when you start the process let me know and I'd be glad to talk you through it. 8)

I've been down that road many times. :Wink:

I am thinking of replacing the crankshaft only on this engine. What other parts do I need to replace since I will have the engine removed.

You will need all the main and rod bearings, as far as the rods go, it really depends on what you find when you get in there.
If it is a rod bearing that's making noise you should be able to determine which one it is before you get into it. With it running you can unplug one injector at a time and listen for the change in sound. The one that causes the most drastic change in the knocking noise is usually the failed bearing :wink:

I have managed to take the engine out and I am dismanteling it.

I got the pushrods mixed up and a couple of them fell on the floor while I was removing the heads.

Is it ok to reuse these or should I replace them.

Sorry it took me so long to reply, I was out of town for a couple of days. :Wink:

the push rods are all the same length on this engine. As long as they aren't bent you should be ok. :)

Thanks for your reply Xowey.

BTW the engine is rebuilt and back in the car. It is working fine. I am pleased so far. The 500 KM oil change just came up, so I will have a look at the oil coming out of the engine.

I have a question though. The temperature guage stabilizes at the second mark when the car is moving however as soon as I stop the temperature rises to the third mark and then falls back when I start moving again. The guage has 4 marks before it gets into the red. I changed the thermostat and the fans seem to be working fine, the coolant level is fine also. I was wondering if this is normal.

Any ideas.

Oh yea, that's normal with the a/c off, the fans only run above a certain engine temperature (about 225 f) :wink:
with the a/c on they come on with a/c pressure activation
is it more stabalized with the a/c on?
