Re: more from tashasdaddy

will do. i think i'm going to attempt to pressure test exhaust manifolds. and make sure nothing is in Y pipe.

Re: more from tashasdaddy

I wouldn't worry about trying to pressure check them, just fill them from the bottom and see if water gets into the exhaust portion. If it does, they are leaking. But even if they were leaking severly, with the engine running, the exhaust would push most of the water out the exhaust, not into the crankcase and start overflowing the oil.<br />There is a major leak somewhere, and it's not the exhaust, unless there is one cylinder with no compression and a hole in the piston.

Re: more from tashasdaddy

my God, i might be figuring out something on my on. thats exactly what is was going to do 1st. i may not be hopeless yet.

Re: more from tashasdaddy

I've seen the no compression/bad cylinder combo/bad manifold riser first hand ......You will get plenty of water in your oil pan QUICK!...Do the compression test....JK

Re: more from tashasdaddy

i think i'm to a rebuild. retested cooling system with water to be sure. no leak down at 18lbs. while i had water to it i reconnected exhaust hoses and ran water thru the manifolds. used long bolts to support mainfold (old batwing) no leak. now i can't get to turn over. harmonic pull moves about 1/2" with each bump of the starter i have pulled plugs to relieve compression.

Re: more from tashasdaddy

You need to pressure test the cooling system with AIR, not water!<br />Are you saying you can't turn the engine over with the plugs out??? Is there water in the cylinders?<br />Did you ever pump out all that milky oil? OR is the crankcase still clear full?

Re: more from tashasdaddy

i've gotten a lot out not all. just found out this engine was submerged. they left the plug in the boat and it filled up over the engine. now i know why i got it for free. at least it was fresh water. i don't know how long it was submerged. i found out from a friend of a friend.

Re: more from tashasdaddy

Do a compression test.<br /><br />Just because the engine was submerged does not totally condem it. <br /><br />Also if your pressure testing it properly and it holds air pressure it will hold water. <br /><br />

harmonic pull moves about 1/2" with each bump of the starter

If the head gaskets are'nt blown, trying to start the motor with water in cylinders is a good way to blow them out.<br /><br />

tashasdaddy <br />Member # 67942 posted December 26, 2005 01:25 PM<br /> <br />tried it again dry, started 1st try. then we water, repumped oil stick, same thin skim milk. it runs to good . where is the water coming from. didn't find water in #5, could it be a head gasket on starboard ,as that is the side shooing the water 3 times as much as port. or do i have a crack head or block. it runs too good . what is the best to clean this goo?, can't see what i'm working on. bilge is the pits, thank god i have a stepped bilge. <br />

If the engine has a head gasket problem it wont run to good <br /><br />Do the compression test.

Re: more from tashasdaddy

can't now, until i get it to turn over freely. plugs are out. can't turn manually, starter turn main pully 1/2". i don't want to burn the starter up also.

Re: more from tashasdaddy

pay for my gas, find me a cheap hotel close by, i can pay for that, and i'll come up saturday am and give you hand. <br /><br />i know about as much as you do but i have my motor apart and am waiting on funds to come in for the manifolds..........<br /><br />if i didn't drive a 19' 4x4 i wouldn't ask for the gas.............

 

[tashasdaddy]

Re: more from tashasdaddy

dan i don't know where i'm going with this right now. i'm like you waiting on funds. i have a budget for toys that i have to live with. i have to slowly get the idea across that i my have to pull this engine and rebuild it in the garage, where her car goes. fat chance.

 

[shelikesit]

Re: more from tashasdaddy

yeah i don't know where i'm going with it either, i wont put toy parts on credit cards so the internet is going to have to buy my manifolds, which it will. <br />i have the heads off and am slowly cleaning the goo that i can get to from the top....... i heard DonS say something about diesel fuel and that's what i'm using, spraying it and sucking it out..........<br /><br />plus i had the time so i offered

 

[tashasdaddy]

Re: more from tashasdaddy

appreciate the offer. found FORMULA 88 at lowes yesterday. it does a pretty good job. spray on let sit hose off. don't drop the socket into the bilge, nasty, did it 3 times today, like sticking your hand in s---. i imagine.

telescoping magnets, 3.99, orange handles, counter @ autozone............. <br /><br />i sailed abroad for 5 years on the JFK about 20 years ago, after a few times in some areas, you can put your hands in anything

Re: more from tashasdaddy

Can you turn the engine by hand? Also try turning it backwards then forwards. What position is the outdrive in? Down, I hope.<br />If you have to. take the belt off and use a strap wrench to turn the engine.<br />I've seen bad connections, bad starters, broken starters, etc. causing the starter not to crank the engine.<br />Most of the time with hydrolocks people keep hitting the starter trying to get it to crank and end up breaking the nose off the starter. Then when you try to crank the engine the starter binds and won't turn anything. Nothing wrong with the engine, just the starter.

Re: more from tashasdaddy

it is locked up good. plugs out. tried turning by hand, with strap wrench, drill holes in a 3' long steel angle bolted to harminic balancer. wiil not move either way.

Re: more from tashasdaddy

Too Much water, for too long a time. <br />You also had a "Good running engine" with a NON leaking cooling system that is filling the crankcase with water. Sorry, but those things can't fit together. Your free boat is now getting very expensive.

 

[tashasdaddy]

Re: more from tashasdaddy

don, am i correct in thinking i am going to have to pull the engine, and do a rebuild or by a reman. if this is the case it won't hurt me to wait for a couple of months. it's got about 3 qts of diesel fuel in it and the rest of the crud. i think i know when to bite the bullet.

 

[shelikesit]

Re: more from tashasdaddy

have you pulled the heads off to at least see if those gaskets have long gaps in them???? sorry i didn't see that anywhere. that's where my water problem was...........<br /><br /> http://forums.iboats.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=24;t=015147;p=#000015 <br /><br />i should by all means pull my motor, but it would only to be to clean that crud from the pan. overall outlook is that it can breakdown with oil changes. much easier to do a couple suckouts first than yanking that motor out. i think i don't want to see my transom right now. i think it'll open more worms.<br /><br />we use shrimp and whatever they catch for bait down here, don't need no more worms right now

Re: more from tashasdaddy

am i correct in thinking i am going to have to pull the engine,

It's no good the way it is, and only pulling the heads is a waste of time. You also need to see what the main and rod bearings look like. And you can't do that with the engine in the boat.<br /><br />

do a rebuild or by a reman.

That depends on what the block, crank, heads, cam, etc. looks like, and a lot to do with your mechanical skills. Rebuilding an engine is not just following steps from a book, but knowing what to look for both in the old parts, and fitting new.<br /><br />

if this is the case it won't hurt me to wait for a couple of months.

Water and steel creates rust. The longer rust exists the worse it is. Your engine may be rebuildable now, but not in a couple of months, or days for that matter.<br /><br />

i think i know when to bite the bullet.

Not really, in all the time it has taken you to "fix" the manifolds on an engine that ran "Fine", it's now locked up...... You might want to restate that as "i think i know when to open my wallet."<br /><br />I have this funny feeling you are starting to understand that being a boat mechanic is not as cut and dry and easy as most boat owners seems to think it is.
