AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Somebody went to the Golden Arches, bought seven quarts of chocolate milkshake, and dumped it into my crankcase......again. (heavy sigh)

This is after a new motor, heads shaved, block deck shaved, thousands of $$$$ invested.....what more can I do??? I can't stand it anymore.

There are plenty of threads on this site about milkshake oil with postings from some pretty damn smart guys. I appreciate all of them. This is a great website.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

did you replace manifolds?????

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Could you be experiencing reversion? What are your cam specs? Whose exhaust are you running?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Intake manifold install problem?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Is it slightly contaminated or is it MR.Softee?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

thats where i'd look first. hey what happended to the ask JC thread?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Jassman got it poofed.Start a new one :D

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Oil-cooler?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Oil pressure is greater than water pressure

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Not when the engine's off....

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

could be many things he did say to much as to what he tested or replaced prior to running boat we can all throw things against the wall and see what sticks but it better if he just gives us alittle more info!!!!! :rolleyes: :rolleyes: :rolleyes:

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

You will notice a drop in oil level.It wont batter the oil bad.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Guys -

Thanks for the feedback.

I'm running a Whipplecharger/intercooler setup and a stock 502 cam. Since my last oil change I noticed a little sludge in the valve covers and wrote it off as normal condensation. It was after the last run that things got ugly.

I am running IMCO powerflow exhaust. I pulled the risers and didn't see any water in the exhaust. The riser gaskets looked OK.

The oil is contaminated enough to change the color and slightly thicken it. Kind of like a completely melted smoothie. I didn't notice a rise in the level but it is hard to tell.

I didn't want to pull the intake because it is such a PITA with the Whipple but it sounds like I may need to. I need to rig up something to allow me to pressure test my oil cooler too.

Another piece of info: Last time I had the intercooler off, I noticed that about half of my intake bolts were not torqued to spec. I retightened them. Maybe I screwed something up.

Is there a way to get all of that crap out of my motor other than changing the oil 6 times?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Sounds like an intake gasket leak

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

I use diesel fuel to thin-out the sludge and pump it out.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

I do the same thing. I'll put in half oil, and half diesel, then run it for a couple minutes. It will cut all the emulsified oil that's all over the engine.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Have to agree with jc sounds like intake check around the water cross over in the manifold where it meets the heads

and if you add diesel or kerosene to the oil as ed said it will work wonders

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Had a buddy last year that had a bad section of exhaust hose. When it got running the inside of the hose flapped down and acted as a check valve causing water to back up-check your hoses carefully. If not, it's likely the int gasket.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

I had problems getting the intake to seal also on a B&M blower intake at 1st that would dump water into the oil a qt at a time in less than a couple minutes. I used to just do the torque sequece 3 times until at the final setting. Problem was, after each round, the 1st bolt was hardly finger tight because I now had pulled the intake down tighter. learned to keep on going around the torque sequence until the 1st bolt was still at the final torque once the last one was torqed. Wasn't uncommon to make close to 10 rounds. The factory intake was never a problem. Got me why the difference.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

what kind of water pressure are you running?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Panther -

About 23 psi @ WOT which is probably near the upper limit of where I want to be.

All -

Assuming I will need to pull the intake manifold and replace the gasket, does anyone have a recommendation on the best BBC (502) intake gasket (brand, p/n)?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

either merc or felpro W/ aviation permatex

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

1274 Fel-pro

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Check the intake bolts 1st before you do anything to either confirm or eliminate the intake not tight allowing water to blow past the intake gaskets. While I was chasing down my problem, the gaskets always looked good with no signs of leakage. I probably could have just tighten the bolts down and been good to go, then replace the gaskets once the problem was found.

Are your water passages corroded on the intake gasket surface on the intake?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

What is the end gap at the front and rear of the intake manifold, ck both sides with a feeler gage to make sure you have clearance and the intake is fitted correctly.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Try pressurizing the system ? It will eliminate reversion possibility. Last spring a friend of mine put 2 brand new intakes without checking the gap around the water passages. When I removed the int manifold it was clear to see the gasket had more crush on the the top than the bottom. The other side was just fine.
Had a problem a few years back & replaced the risers with Sierra's. Turned out it was the design of the piece of S**T aftermarlet risers. Replaced with merc's & solved the problem.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Oil temp? how are you venting the valve covers?

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

What intake are you using ? Also intercoolers are known to leak. I like the Cometic gaskets. But the felpro 1275's work well for me. What temp. is the motor running at, this could be a dead giveaway to the problem. BBB

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Heads shaved, block deck shaved? You may have incorrect geometry causing poor intake to head sealing. I've seen this happen before.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Thanks for the part numbers.

I'm running the Whipple supplied intake manifold. The setup uses a crossover so my water temps rarely get over 100°F when I am running.

Oil temps spend most of their time warming up to 180°F, then peak at 190-200 for short bursts when I finally get to open it up. My valve covers are vented with a single small breather over the starboard cylinders, and a PCV valve on the port side.
Is there a chance that this is condensation? The oil was pretty crappy. How many boat trips in colder weather does it take to turn oil into chocolate milk?

It sounds like I may eventually have to pull the intake and have a look. In the meantime, I will probably figure out a way to pressure test the block. Anybody done this before? What do I need?

As I mentioned before, I did find a few loose bolts on the intake the last time I had the intercooler off. Unfortunately, some of the intake bolts on the Whipple setup are actually in the plenum area so you have to remove the intercooler to get to them. I'll still check the torque on them before taking them out.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Interesting...I've never heard of that trick. Are you guys sure that won't take away too much lubrication to the bearings? I've been there and it's definately a mess to clean!

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Grog,

there will be a lot of different opinions out here. If the oil doesn't see 212F and you have poor crankcase ventilation you may have condensation problems.

I personally like to see 140F water and 220F oil.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Very possibly, condensation. How much does the level rise on the dip stick ? If alot it's not condensation. Any good machine shop could pressure test. Some mobile marine mechanics also have pressure testing equipt. Was the block sleeved ? Also have seen cracks in cylinders low in the bore that only open and leak when motor warms up. BBB

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Not if you are just running it at the dock. And keep your hand off the throttle. BBB

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

I agree with this answer, I had the same milking problem with the oil, put in a thermostat or flow restrictor on the the water. Arizona Speed sells 120 thermostats for this reason. Also, if you have a big 3" oil cooler with without a oil thermostat this will cause the same effect.

Is the oil in the pan milky white? if so, you will need all new bearings has they have been whipped and will go away. Condensate issues do not change the oil in the pan color unless it done for a long period of town. If the oil turns white after a quick blast, you have an intake or head gasket leak.

EITHER way, a rebuild is in your future.

Personally, I prefer the Mr Gasket intakes. Fel Pro leak to often.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Sounds like condensation - just a little water will make it look bad. RacinFever on this board is a master at fixing these types of probems - PM him..

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

I hope that you guys that were helping me with this are still out there.

I pulled the exhaust mainfolds and found about 1/8 cup of water in the #8 exhaust port (in the manifold side). I also noticed that the when I peered into the exhaust ports of the heads with a flashlight, the valves on #4, #6, and #8 were a tan color compared to a white/grayish color on the other cylinders. My plugs all looked normal (or at least the same as each other).

I pulled the valve covers and found what I expected, lots of yellow snot (for lack of a better term). I dumped about 2 gal of diesel on top of the heads and let it wash into the pan (old oil had already been drained). After letting that soak for a while, I pulled the drain plug. The diesel fuel came out yellow. No surprise.

I pulled the intake manifold and WHAT A MESS!!!!!! Of course, any evidence of a manifold water leak was destroyed when I seperated the intake because the gasket ripped apart.

Here is what I am struggling with. If the water is coming in from the exhaust (reversion, riser gasket, manifold crack, etc..), how does it get to the oil pan? Does it have to leak past the piston rings when the motor is off? It seems like if the motor is running and this happens, the water would just get forced back into the exhaust as steam.

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

your leaking past the rings theory is on the money, thats how it happens!!!!!

no need to look farther in the motor now that you know its on the exaust side :evilb: :evilb: :evilb:

now all you need to know is what is causing it on the exaust side...... :drink:

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Something's amiss

Re: AAAARRRGH!! Milkshake AGAIN!!!!!!!
 

Yup, before you put the intake back on, make a cardboard (hardboard) template of the angles between the heads. mark where the water and intake ports are. Then make a transfer (negative)of this and check it against the intake manifold. It will tell you if the angles and distances are correct. Keep in mind the thicknes of the gasket when you do this.
