Help a family diy guy out please

I'd be surprised if it didn't repeat itself (with the caveat, I hope it was a fluke!) As far as freezes go, the intake would be the cheapest and easiest fix (shouldn't have to pull the motor. Just pull off all the connections, hoses, linkage, remove carburetor and then remove the intake. Is it MPI or Throttle body injected? A real quick on ebay gives me a 4.3L intake (marine application) for $295.00. Add gaskets and RTV and you're back in business...make sure that's where you leak/crack is before buying anything...if it's the block...local rebuilder short block...if it heads, junk yard...

The dipstick will show if it is looking like Mocha again. If it looks good after the running, check the oil level. Later, wait till the engine has cooled down, then recheck the oil level. It is possible it isn't leaking while the engine is warm, but once it cools down and parts contract it might slowly leak. Then I would suspect a gasket.

There is another possible explanation, the shop that did the winterizing... You said you spoke to the tech that did the work. Was he the only one who worked on the task of the winterizing? Some shops like to put an antifreeze into the hoses and water jackets after draining the water. Maybe someone dumped the antifreeze into the crankcase instead of the cooling system. I know it sounds like a longshot, but unless a leak is found...

What about the riser/exhaust manifold gaskets? They are one of the weakest point and often responsible for water ingestion.

There is no connection to the crankcase with exhaust, well if there is crack in the head. I'm not 100% sure but I don't believe that year of engine has a heat riser passage in the heads or intake manifold.

That's a possibility but you would only get a little bit of water in the crankcase from when you shut down the motor. Normally, not enough to cause a milkshake where it spews out enough to cover the intake manifold

Well as we all thought after running it for about 15 minutes on the lake right back to milky crap spewing out found out it spewing out of the valve cover breather hose which then squirts all over the intake it was still running real good this time so now I'm leaning towards an intake crack so I guess my next step is I'm going to try and figure out how to pressurize this cooling system can somebody point me in the right direction for the tool that I need to pressurize this

I did a compression test last night and all 6 cyls at 120 solid

You may also have a serious crack inside the exhaust manifold. Remove the drains and see if lot of water comes out.

 

[bruceb58]

A crack in the exhaust will not put enough water into the crankcase to cause that much oil to spew out. It will also only leak after the engine is shut down.

Compression tests will only show you have a problem with a head gasket. Your problem is way beyond what would be caused by that.

You will have to get a little creative to pressurize the coolant passage. Will involve getting some pipe fittings to block off all the water hoses and a way to plumb in a schraeder valve and a pressure gauge. You will want to pressurize to 15 PSI.

ok I have a good mechanic now and he removed the intake and bam 4 huge cracks. he says the block is ok and that after a new intake it will be ok. he said autozone has an edelbrook intake that I can use but he says best thing to do would be buy a new Volvo intake from e bay. have anybody used a autozone intake before?

 

[bruceb58]

The edelbrock is likely aluminum.

The Edelbrock Performer Vortec V6 is a nice manifold. It is aluminium, however the current manifold might be too. The Edelbrock is a 4 barrel manifold and you would need an adapter to mount the Holley 2 barrel. If you do all your boating in freshwater, you don't have to worry about the Aluminium. No matter which manifold you get, do it ASAP, as you need to get the Mocha out, and fresh oil in.


Pics of the cracks please

​pics please...so, if it's the intake, you can only blame your lack of knowledge on the intake drains...luckily, the cheapest of the fixes! As I've learned and lived, stupidity is pro-rated!

Ive,tried several times to upload pix. It keeps telling me some type of error or another. Did the linked pix from page one work?

 

[Four winn probs]

And I didn't winterize this boat. A shop did but they didn't drain the intake. I will after all this tho. Ware can I buy this fog stuff to spray in the carb when winterize?

Ayuh,..... Lotsa questions bein' asked, 'n no answers for 'em,......

Is the motor carbed,..?? 2bbl. or 4bbl,..??
Efi,..??

Do ya boat in saltwater, We don't know where you are,....

Post yer pictures at a photo hostin' site, like photobucket, 'n then link 'em back to this thread,.....

2 bbl carb 1999 vertec v6. Fresh water only. Pretty sure she will be up an running by tomara. I found a nice used intake local for 125. It's not cracked but the block I pulled it off of was cracked all to hell. I dropped off the new intake this morning and he sent pix of the gaskets he bought around noon so I bet hell be done today

Does this linked pic of my boat and captain work

Ayuh,..... Yer younger than I woulda thought,.....

If ya click the image button in the post editor, 'n paste that link into the bubble that comes up,....
You'll post the picture in the thread,....

Or, put a

at the end, the picture will post,.....
