friend is in need of help please milky milky oil

[bolo78910]

a guy in my marina has been trying to get his boat running one year, and still no dice, tonight i decided i will lend him a hand,.

1979 Searay 29 foot twins 454 engine serial #961959 firing order 18436572.

where do i start, well he claim he got both block rebuild, now he has water in both engines, milky milky oil, he claim he change the power steering cooler because someone told him that why he gets water in the oil, ha, any to make it short he change the risers and manifold on one engine, today i try starting it but it will not catch but it does turn over.

i took out number one spark plug get the engine to top dead center because it was way off,

i re wire the plugs which was also wrong, boy oh boy,

i try cranking it over again no start, i am getting fuel but it seems as if there is no sparks, why i took the wire from the coil put a screwdriver in the wire ground the screwdriver to the block have him crank it over no sparks, . now what.

last it has a close cooling system, which i think all the hose was just wrong , they have the two hose from the thermostat going to the risers, so all the anti freeze was going over board, when it start. they has no block off plate between one risers and manifold, by the way it has the old logstile manifolds.

it also has points and condenser. now guys if all the hoses was rout totally wrong should that cost water to get in the engines, or if the firing order was wrong will that make the engine spins backward,

dons can you post the diagram for the close cooling system for that engine with logstile manifolds thanks.

Re: friend is in need of help please milky milky oil

upps i think i was checking for spark the wrong way, i pull the coil wire from the coil i think i should pull the other end that goec to the distributor>>

 

[oops!]

Re: friend is in need of help please milky milky oil

sorry for the delay! all operators, are currently busy, don s and bond-o will be with you in a moment!....tee hee.

hang in there helps comin!

if i remember correctly, in my old cc system, milky oil meant not good!

if i read you correct, bolth motors have milky oil and dont get fire to the holes?

if you dont get spark, search, motor doesnt start thread. don s posted a perfect trouble shooting guide, compleate with pictures and diagrames!

i can only guess if bolth dont fire, its gotta be a loss before the engines. check the shifters.

and sorry to say.... i think they frooze and the blocks are cracked. thats why the milky oil. i have no experiance with twins, so my 2 cents worth is only worth a half a penny, but i did have a cc and water should not be able to enter the block at for any reason!

best o luck bud!

up date the boat has no out drive it has that transmission looking thing at the back of the engines. thanks so far i will do a search,

Re: friend is in need of help please milky milky oil

To check the spark, pull the coil wire off the distributor cap and hold it next to a good ground about a half an inch. The spark should jump that and be a bright blue.
The sn you listed, isn't a good number. To short.
Assuming you have a 79, Mercruiser 330 motor. Are they straight shaft drive, or are they Vdrive? Is one of the engines counter rotating?
When checking your firing order, don't forget the engines may set in the boat backwards if it's a V drive. When you do the firing order, make sure you have #1 on the proper side of the engine.
Standard rotation firing order is 18436572
Counter rotation engine firing order is 12756348
Does this engine have center rise manifolds and are the manifolds also part of the closed cooling system and have AF in them?
Do these engines have electronic ignition, or points type?

Water in the oil? It does have an oil cooler. You need to pressure test it.
Since it has a closed cooling system, did it have antifreeze in it? If it was just water, it would still freeze.

Re: friend is in need of help please milky milky oil

thanks don s it is a fresh water cool engine, both engine was rebuild by a so call good builder, the novises that he got to put back the engine together dont have a clue about boats they might works on cars , when he show me the engine last week it has one of the head off and was at the mashine shop because one guy told him that why the engine got water in it.

so i told him have the guy install everything back and if he have a prob call me then, so here we are, close cooling systems with seawater pumps heat exchanger, log stile manifolds they have two hose from the thurmostat housing going to both risers, that a no no the side he took of on that side he install a new manifold/risers i notice there was no metal gasket between the risers/manifold, pointed it out he stated that how it sopose to be, i took the old manifold/riser apart just to prove him wrong behold the metal gasket, so that shut him up lol.

it has points /condenser the rear of the engine has something like a transmision, i think it has drive shaft i did not notice.

he claim he put i new oil cooler also. the port engine is the one iam messing with now with firing order 1836572 i wire the plug wires just like my engine don, so what you saying is that the other engine has to be wire with the oposite rotation.??? last what the v drive should look like thanks.

Bolo


YOU really need to take some pictures it will really help people understand what your working on

I'm with Tommays, take some pictures, of the engine, and the transmission.

Re: friend is in need of help please milky milky oil

up date here guys i dont have a digital camera so i cant take any pic , tonight i went back to the boat , and i i stated before i was testing for spark the wrong way, well tonight i did it right and i got good spark , with the guy cranking the engine i got it fired uo and running smooth as ever , i told him to pull the dip stick in the morning to see if the oil is milky.

i told him he needs to change the other risers because the side with the new manifold/riser is running cool while the other side is a little hot, i also cut re route the hoses for the cooling system.

he got a service manual so i just follow the dirgram,

one more engine to go, i told him i will not touch it antil he got some new risers, thats why he got water in the engine in the first place, take a close look at the bad risers it has a big hole inside,.

will keep you guys posted, last at the rear of the transmission thing there long shaft leaving it. on the valve cover it says 330.

Re: friend is in need of help please milky milky oil

maaaan, you buds in a WORRRLD of hurt!!! first of all, who the hell rebuilt those engine? is he sure they were rebuilt? i hate to be the bearer of bad news but it sounds like your friend was taken...

ok, so milky oil... it's one or all of the following: bad head gasket, crack in the block (allowing coolant to seep into the crank case or lifter valley), you have a very bad seal in the joint where the coolant flows out of the cylinder head into the cross over of the intake manifold, OR a combination of all three...

secondly, regarding your exhaust manifolds, it sounds like you have a block-only cooling system, where the engine is FWC, but the exhaust manifolds are still on the raw water side. if the whole system (exhaust manifolds included) are FWC, then the themostat is mounted directly to the heat exchanger, it has to be or the manifolds would overheat. if the thermostat is mounted in it's proper location on the intake manifold, then only the engine is FWC, manifolds are raw-water cooled, meaning the sea water flows into the heat exchanger, then from there flows out into the base of the exhaust manifolds, up into the risers, then out the exhaust.

ok, now onto timing. the best thing to do, is pull out the plug on the no 1 cylinder and put your finger over the hole as your friend cranks the engine, when it comes up on the compression stroke, you'll feel the force of the compression. it may take a couple of revolutions to learn the difference between the compression stroke and the exhaust stroke.
either that or you can take off the valve cover bring the piston up while the intake and exhaust valves are closed (which you can easily see b/c both springs won't be compressed at all). bring the piston up and then you can relocate the distributor to reflect the no 1 cylinder (industry dictates that the rotor be pointing at the no 1 cylinder intake port when the cylinder is at TDC). it should fire.

you sound like your in a world of hurt, if i can be of any assistance, let me know, you can call me if you want, anything to help a fellow boater!

Re: friend is in need of help please milky milky oil

thanks cizzo, i got one engine running so far by doing all the above pull the distributor, get it on tdc ect, so now she is running fine, but ges what i did i route the hoses so now it is manifold an engine block cool, i think that how it was because the old riser/manifold that he took of has the metal plate between the riser and manifold. the new side is running nice and cool but the otherside with the old manifold/riser is running hot, i told him he better change them both or at least change the riser.

so far one engine down, that is the one with the counter roatation wiring, never did one before, i ges i jus wire it conter clock .

that is the engine that got the most water in it. if you see how rusty inside those risers look they got to be the culprit for water getting in the engine,
i told hime if he dosent get at least new risers i am not going to turn a screwdriver on that engine, lol and i meant it.

thanks guys i will post my outcome
