no oil to push rods

[henry1357]

Hi everyone
i have just purchased a sea ray 220 with the engine completely in dismantled.

the engine is a 6.2 mpi v8 mercruiser 2004

i have managed to get it back together and running apart from the fact there is no oil coming out of any of the push rods.

i have only fired up the engine for about ten seconds and shut it off strait away.

do i need to run it for longer to get the oil up or is there something wrong

thanks in advance

henry

Ayuh,.... Did ya Clean out the centers of all the push-rods,..??

The lifters push the oil up through 'em,...
'n Ya, it'll probably take longer than that,...

Primin' the oil system would Help,...

Thanks for reply

No didn't clean them, rookie mistake, prime the pump with a home made tool and pump is definitely pumping oil (checked it with filter off).

there is no oil coming from any pushrod or lifter, could it be anything else apart from blocked pushrods because surly at least one would be clear

regards

Ayuh,.... The push-rods won't show oil from primin',...
It's the action of the lifter, that lifts the oil,....

Put a mechanical gauge into the oil sender hole and make sure absolutely positively there is oil pressure. Never assume something that important. The engine was dismantled... why? Any machine work done? New parts? Cam bearings? Rod bearings, crank bearings? I have seen fellas install cam bearings so the oil holes dont line up and wrecked that motor pretty quick.

Re: no oil to push rods

If the lifters are adjusted incorrectly:too loose,they won't pump either.

Re: no oil to push rods

To prime the engine using the oil pump, you need to insert a dist body in the hole. just spinning the pump shaft will not push oil to the lifter gallery.
"i have managed to get it back together and running apart from the fact there is no oil coming out of any of the push rods."
Can you elaborate on how much was apart and how much you put together, and what your experiance level is putting a motor together.

Re: no oil to push rods

hi guys

right here we go, my mechanical knowledge is limited but i am pretty confident with engines and am not afraid to ask if i don't know.

i found the boat on advertised online stating engine need work, boat is 2004 sea ray select 220 in very good condition.

after talking to the owner he told me that he lost forward and backward movement coming in to dock and put it in the marine mechanics for a diagnosis (which turned out to be spun coupler), they also told him that the boat needs another service as well (same mechanics had serviced it 1 month before) then he gets another phone call telling him they have stripped down his engine as they found swarf in the oil pan (small amount) at this point he told them to stop work as he didn't want to spend any more money on the boat.

I paid 7500 for the boat with the view that it needs a new long block but after inspecting all the engine components they all looked in very good condition so decided to spend a couple of days putting it back together and see what happens.

As for how far it was stripped down, the cam bearings were in and the heads were complete, the rest was in pieces, pistons and big ends were numbered, push rods and lifter were not.

once i got it back together i primed the oil pump with a home made tool and fired it up, engine started instantly.

sorry for long winded post

thanks in advance

Re: no oil to push rods

Is it possible that something is wrong with distributor, not turning the oil pump?

 

[henry1357]

Re: no oil to push rods

no the distributor is in good order

Re: no oil to push rods

Grub is most likely right, the lifters need adjustment. You only had it running 10 seconds or so, which is not enough time. Fill the oil filter with oil, Prime it by hand until you see oil pressure on the mechanical gauge. Then start and idle. The bottom end will have oil and eventually you'll start seeing oil up top. You may want to use deflector clips on the rockers, I've seen oil go squirting out and ruining interiors, hitting mechanic in the eye causing him to exclaim "Dagnabadingdong!" and drop his socket wrench on the balancer which then ricochets up and out of the boat and goes through the windshield on the wifey's brand stinkin new $60,000 Lexus bouncing off the dash and careening itself through the rear window shattering it and causing an electrical short in the back wiper making it flip flop back and forth ineffectively. You decide to attach a little American flag to the wiper arm while crying and wondering if the insurance company is gonna say it's two separate incidents and your 1000.00 deductible applies to each one separately.

Re: no oil to push rods

Did your priming tool use a dist body or just a rod to spin the oil pump?

 

[henry1357]

Re: no oil to push rods

lol walt will try that

@bt doctur i just used a rod in a battery drill

 

[Bt Doctur]

Re: no oil to push rods

Thats why, a dist must be inserted, thats what directs the oil to the lifter gallery .
Without a body, you can look in the hole and see the oil just spashing around.

You're not going to be getting oil to the top end if the dist. isn't in the engine. The oil comes up the back side of the engine from the filter and goes to two places, the left bank of lifters and to the dist. where it then goes to the right bank of lifters. Without the dist. (that is what the rounded cavity in the bearing surface is for) you won't be getting any pressure and definitely no oil to the right side.
This is true of all of the SBC engines and I think that the BBC engines are done the same way. The only variation is the first year of the V8 where the oil also went through the back of the cam which means that they need to have some work done on a standard cam.

Re: no oil to push rods

the diet was in the engine when i ran it (only about 10-15 seconds) shut it down because i didn't see oil at rockers

Re: no oil to push rods

Let me re-phrase it:
When you do a rebuild and pre oil the motor thru the oil pump using a old dist body with the gear machined off, it may take 10-20 minutes of priming until you see oil coming out of all the pushrods. Once all rods are showing oil, and you have turned the crankshaft a few times to eliminate all air pockets ,then you install the dist and fire the motor.
