pulling the engine today:)

got the engine out! It was a chore by myself, as always. I will start my investigation tomorrow on a possible internal cracked block
here are some pics

That must have been a tight squeeze getting that out with the back seat still in the boat.

Nice you were able to use a cherry picker to get it put. Keep us updated!

more pics, I'm calling it a day!...and yes, it was a tight squeeze getting that engine out, but once I got it turned sideways, it was no problem
I have found that blowed out plug, still keeping my fingers crossed that the block is not cracked internally. I will keep moving forward...wonder if I can pop that plug back it, so I can do that pressure test on the cooling system

That was kinda risky using the oil pressure sender as a hoist point, I wouldn't have trusted that but I guess it worked. Also looks like one of your starter bolts is hanging out of the block. For the freeze plug I would get a new one and tap it in with some pipe sealant. Looks like they use brass plugs for marine environment.

good eye, that chain is just hanging there, not attached to that oil pressure sending bolt

I know better than that lol

I'm envious that its nice enough to work outdoors where your at. Looks like your project is progressing nicely. Looks like you have the skills and equipment to get the job done.

it was sunny outside yesterday, but cold. I can say that I enjoyed every minute of working on this project
My skill level always improves with great, correct, advice for folks that are willing to give it. I have been wrenching for a long time, but, "if your not willing to learn from someone else who has BTDT, then all you know how to do is hold a wrench...."
I do have a lot of equipment, and tools, to get most jobs completed that do for customers, however the tools that are needed for working on this engine, are outrageous in price. I will be asking a lot of questions about these so called " Special tools"

just as some expected, rear core plug aka " Frost, Freeze Plug" was pushed out the rear of the engine block, looks like it is in good shape. I may re install temporarily just so I pressure test the block cooling passages
opinions appreciated

Jerry · « **Reply #93 on:** February 16, 2014, 11:23:59 AM »

They make an expandable frost plug you put in and tighten.

update!

I did some more troubleshooting today...

The core plug looked really good ( will purchase a new one), but I cleaned the edge of the brass core plug aka "freeze plug" with my buffer, and cleaned up the rust that was around inside rim of the core hole in the block.

I then re-installed the core plug back into the core hole in the block,( *****just temporary, so I can air pressure test the block*****) using some gasket sealer on the edge of the freeze plug.

I then setup to air pressure test the cooling passages in the block...with oil pan drain plug removed

I hooked up my hoses, clamps, pressure gauge, ect, induced 20psi into the cooling system. I immediately saw the pressure gauge start to drop by lb , "Oh crap!!! maybe I had an internal cracked block", I really said a few choice words, other than " Oh Crap" .

I then got my bottle of soapy water, re- pressurized the system again to 20psi, and started spraying all my hose connections that had clamps. as the pressure was dropping I located some major leaks around the hoses, so I tightened up the clamps some more.

I got all the clamps tightened, sprayed soapy water on them again, no more bubbles

I induced 20psi again into the cooling system......it held pressure for 2+hours, maybe even longer. I did not unhook the air until I got up all my stuff that I had strolled all over the place today. The last thing I put up was that air hose probably about 35 more minutes later

so IMO I feel like my block does not have a crack...that is IMO on the block only

my next test will be a cylinder leak down compression test

I would appreciate opinions good or bad, they all help

That bearing definitely needs replacing. Looks like more than just water in those bellows, like gear oil too. Your upper yoke seal looks like it may be leaking. I've replaced a lot of those but sometimes you have to replace the short yoke between the 1st U-joint cross and pinion drive gear. The reason being is a slight groove gets worn in the face of the yoke where the seal rides on it, and once a groove is formed it will continue to leak even with a new seal in the carrier assembly.

just thinking about the water in the u-joint bellows
after examining all that I could see of the bellows, they have no dry rot, no holes, clamps are tight but not over tightened., in the correct position per the FSM. I feel like the water I found in the bellows, may have come from inside the boat, is this possible? I was thinking maybe, because of that leaking rear freeze plug, and possible leaking intake manifold
here are the pics again
I can also say that the nuts on the alpha one gen 2 were not even torqued, just finger tight, and the gasket was on the back of the drive, not on the gimble housing, hope this makes sense...any thoughts on this?

Rich_V174SS · « **Reply #96 on:** February 16, 2014, 08:53:41 PM »

For water to enter the bellows from in the boat half the engine would need to be underwater. It's not possible for water to transfer from the engine through the transom assembly, there's just too much if a space to traverse. Are you sure that's all water in the bellows? I still say that's gear oil from the drive. Test it by pouring some into a cup of water. If it floats on top it's oil, if it blends then it's water. Also, if it was water there would be more rust on the U-joints.

Not really. I'm confused by this one.

Hmmmm......

You might have possible things going on. First you obviously had freeze damage because that frost plug popped. You are lucky there. Seems like GM frost plugs usually don't pop and the block cracked. Even though the plug popped it does not mean you don't have any cracks. Could it be that it holds pressure when cold but once the engine warms up the crack opens up. Somehow water got in the oil. If the blocks really not cracked and holds pressure then it has to be a head gasket. Did you pressure test the intake/exhaust manifold yet? If that tests ok, pull head, have flatness checked. Put in head gasket. Put back together and fire it up and see what happens. I wouldn't worry about the milky oil in the bellows just yet. Figure out the engine first.

I agree, i'm not out of the woods yet. I do understand that heat may open a internal engine block crack.
I have not tested the intake yet, that will be this week hopefully
Any suggestions on how to properly do that test?

If it test bad, i will replace it, if it test good, i will do a cylinder compression test, and go from there
Thanks
