OHH NO!! White Smoke and Metallic Sounds!

Well. The verdict is still at large...

I did a compression test without any plugs in the engine block on the passenger side of the boat all test came back btw 130 and 135.

Then pulled the head... and I found water in my cylinders. Check out the pics of the engine here:

The head gasket and exhaust manifold gasket seem to be intacked and in good order.

The drain plug on the drivers side is not in?
The PO had the boat in a garage all winter.

I have been running the boat for several weeks w o issues... changed the plugs wires, and now this...

Another anomaly is the bell-housing gasket is leaking a little.

Taking the head to the machine shop in the AM.

Any ideas?


Cheers for learning the fun way.

Do you have both of your rubber exhaust flaps still on?

dont overlook the intake as being the problem too!!! look underneath where the thermostat is housed, they will crack in the area, it is very thin there

And I saw that...LOL. It almost looks like a rust line, but I hope not. He'll let us know.

Eric, I forgot about the underside of the thermo housing; that was cracked on my 79...along with 2 heads and a block.

remember what daddy said, keep playin with that thing and you'll go blind, i think this applies here

Good eye Chris...and I do need new glasses!

well since you have it off all ready you might has well get a new cam and buy my tricked out heads, exhaust manifolds and chrome intake to dress that motor up and give it some punch.

I also don't see why it was taken it apart at this point. Compression was good, it was time to test remove and pressure test the exhaust manifolds.

I was driving home today and thought to myself that my post sure was out of character for myself and I hoped you wouldn't take it bad! Don't worry Eric, I've got my own wife, 2 kids (in college) and of coarse the bills too!

I'm heading up north for the weekend to get all the boats going. (I'm trying to beat CQ to get them in and running) I certainly hope I don't join the spring time problem group here and end up having to ask for help!

Jamie, Yes, as long as you have gone this far, put water in the manifolds and see if you can spot a leak. A block off plate can also be made to cap the open ports. Then you can pressurize the water which is a better test method.

Wake, sounds like the PO probably overheated the engine (from running out of the water:) and slapped it back together to make a hot weekend. It's happened before.
The head was probably warped when all that happened and he didn't have it resurfaced.
Make sure you have a good tourque wrench and tourque to specs, don't go by this but I think it's 60, 90, and 112 ft/lbs. Make sure the threads are clean and a drop or two of oill on the threads will help give you good torque numbers. Do it in the correct pattern from the inside out. Make sure all your gasket sealing surfaces are clean, clean, clean. You can install the outer two bolts with the exhaust manifold then drop the gasket in. A little spray of the copper coat gasket sealer in the aersol can wouldn't hurt either. I use the grey permatex gasket maker to seal the cork and where it meets the intake manifold gaskets. It really helps to have two people lower it straight down. Hope this helps and good luck!

Checked the exhaust manifold w a water test   no water getting into exhaust.

The head gaskets on the boat were cheap automotive kind. valves had not been done at all.

The compression test had everything from 120 to 148.

Thanks guys!

Not in my experience but if the cylinder (or in this case water passage)next to it is already full of water? I have also not hydrolocked an engine from a blown head gasket either. But I would think both scenarios are a lot more possible with a warped head caused head gasket failure than the standard blowout between the cylinders failure. Its all still a bit fishy though I would definitly be looking for maniford (both intake and exhaust) cracks very carefully.
