Possible Solution

[Zack]

I can get a 24k 04 Cobra Longblock w/ Heads (No blower)
for 3k.
Engine runs perfect, no issues.

Whatcha all think?

I just wanna go fast reliably, and forget about being a big dog on the timeslips page. Its too much $$$ and heartache for that :rolleyes:

[Breadfan]

I know at least 2 or 3 people having a lot of fun with cobra long blocks under their Marauder hoods.

[rvaldez1]

Well Zack, I understand why you are thinking this route, but you are already so far ahead.

[Pops]

Are you thinking of SC or NA Zack?

[MMMAN]

Zack, keep in mind that the Cobra block is cast iron which is much heavier. The good news is the internals are much stronger. The best way is to forge your own, but it's not the cheapest.

[Raudermaster]

Are you thinking of SC or NA Zack?

I think Zack would still probably be thinking the KB since it would be made for that block and probably have less issues.

[Glenn]

Zack:

Been there before with a '67 Mustang fastback. I had trouble after building a highly worked 289 4V. Kept breaking rocker arm studs. I finally just parked the beast for a month and walked away from it. After about the 3 week, I started to think everything through and found the problem. I had a mis-sized push rod packaged by Ford. I checked all the rods for length and replaced 3 of them. Car ran great after that. Walk away from Blue for a month and then go back to it.

Wasn't this on his black car Glenn and not Blue?

I believe the Cobra long block would work for you. Quickest, easiest way to get it on the road again. And I've also heard of several fast, consistent Marauders runing Cobra long blocks.

Yup, everyone's quick to shrug off this avenue because they haven't seen the positive results with higher boost SC'ing which these motors can easily take.

Anyway whats another 50-80lbs on a car already weighing 4400lbs? :cool:

I'm not saying it's the best way to go, but I wouldn't pass it by as a viable and possibly simpler solution.

[Zack]

The car already has a forged engine, but has issues with compression leaking into the cooling system. Im gonna do a leakdown test tomorrow.

Im gonna offer $2700, then sell my shortblock. (After I prove the heads were the problem)

Take that $2900 and go to a competent wrench and have what you already own fixed. Then buy beer with the leftover money.

If you have to lay a hand on it, it might turn to crap and then we'll be seeing a "6th times a charm" thread on here somewhere. Hell, for $2900 I'LL fix it and make it work right!

I used Fel-Pro head gaskets instead of the stock stuff. :flamer:

[merc]

So did I this past time around. :bigcry:

That sucks, because at 17lbs of boost I thought ARP studs and Fel-Pro would be a solid combination.

[Zack]

That sucks, because at 17lbs of boost I thought ARP studs and Fel-Pro would be a solid combination.

There are other problems at hand, not the gaskets.
The stockers showed no signs of blowing out.

[sabtaj1]

Its very hard to blow a head gasket in a dohc 4.6 You would usually break somthing first. Zack, did you do a leak down test on it yet? Say you buy this cobra block. What if one of your heads is warped? That could be the cure to your problems instead of a new shortblock.

[ImpalaSlayer]

could buy some dynamite for less then that. problem solved :dunno:

[BUCKWHEAT]

Doesn't the 04 Cobra have low compression that would kill midrange torque & performance on the heavier MM. Do you compensate with 13# of boost? Just a thought.

[Dragcity]

Zack,

Have you considered there may be a hairline fracture in the block / head somewhere. Sometimes they only leak while in the compression cycle, while hot. Iron will do this as easily as aluminum.

Sorry to hear of all the trouble you have had.

[TooManyFords]

I would think that blown gasket or crack big enough to boil the antifreeze would also be big enough to suck it out of the engine on the intake stroke. If you see a bunch of white smoke in the exhaust then that is the sign of a breach of the cooling system.

I still think it is something dirt simple and Zack just needs to take his time and go through everything methodically. Being the fastest person to R&R a motor is not always a good thing. probably a rag or some ductape stuck in a line some where. Take the burp cap off and watch the flow of water. Make sure it is moving good when running. Remove all the hoses and check for debris.

[sabtaj1]

I still say do the leak down test. Very simple. Just to give you an idea of whats wrong. If it holds the pressure than I would say ur screwed.

[Local Boy]

Hey Zack,

I agree with the idea of taking a step back...and let it go for awhile...

Hold your money, Brutha...It (the problem)will come to you...

You're going to "konk" yourself in the head...When you find it...

It's going to be like, "I should have thought of that!"...

Then a cold beer, will be in order...and SMILES all around...

That's what happened to me when a electrical problem, in the Bronco,stumped me for a loooong time...Walked away for around a month...then came back and found the problem...Hence...the beers and smiles all around...

ALOHA

BTW: Just offering a thought...Thinking out of the box

Is it possible that "compression" is acually "Boost"?

Now that's "out of the box"...

If this doesn't help...at least (I hope) it generated a smile...

Good Luck... Oh yeah, If you need a ride...get a beater for that $$$ (2,900) to use, till you awaken the monstor...

Then sell the beater if you still don't want it...

Have you confirmed that there is air in the cooling system after burping and running it HOT???:confused:

What water pump is on it??:cool:

Without a thermostat (like my setup), you can burp the system without the car running. It took a solid half hour on an incline to get all the air out.

It has a Mezeire and it works perfectly.

Maybe the Mezeire is cutting out under WOT for some reason. I would swap in an old style waterpump to rule the mezeire out.

Christ on a bicycle! How and why it might happen is not the point. Maybe a short or a bad solder joint or the tremendous G's it is pulling, who knows? But it sure sounds like the cause and effect you describe. Being an electrical device, you cannot say with certainty that it is NOT cutting out at WOT.

[Zack]

I am 100% doing a leakdown test tonight.
I even have a special air fitting to just pump max air pressure into the cylinders to be absolutely sure.

[Tom Doan]

I got a new Eaton compleat from T/B to intercooler with all attached parts except for the injectors ready for you, never been started and many on this site saw the set up at MM5, just waiting for a new home. Tom

[Tom Doan]

WHY? I got a Cobra clone from Kar Kraft that lasted 1 hour before it spun a bearing and locked up. I was pissed and bought a new crate Cobra motor from Ford (ouch) took off the blower and used the 1 hour old blower from my dead motor on it and have had 15k miles of fun with no problems. And that is how I have a spare Eaton.
I am debating a blower upgrade,I am at 14lbs of boost, 430rwt all in at 2000rpm and do not want to loose any low end torque by going to a Whipple or KB even if they give me more torque at a higher rpm. I might just Port the Eaton, throw on a 2lb lower pulley and be done with it. Everyone at MM5 that drove my car likes it the it is. Tom

The cobra blower set up fits under the marauder hood?

Jeez John, if it finds a leak, then we dont need to look at the Waterpump,, now do we?

[TooManyFords]

Jeez John, if it finds a leak, then we don't need to look at the Water pump,, now do we?

Depends on if your rings and valve jobs are any good I guess. If it is a crack, you should see it by the rise of coolant in the overflow bottle when you test.

I still say it's not a cracked anything though. You should have seen copious amounts of white smoke in your exhaust from burning coolant or a change in the look of the plugs that were affected or something. Cracks are not one-way check valves.

But hey, keep us posted!

John

[VAmarauder03]

i think both the water pump and the leak down test are good ideas and since the leakdown test requires less time than the water pump why not start with that...he can still swap pumps afterwards right?

[Local Boy]

Now that's the idea...^^^

Aloha

[Marauderjack]

I don't think a leak down test will show you anything on a cold engine but give it a whirl??:confused:

I still think you electric water pump is "Pooped Out"!!:eek::shake:

Marauderjack:cool:

[sabtaj1]

Ya but a leakdown test puts pressure on the whole colant system like it is hot. And if the pressure falls at all on the gauge then you would know that you have a problem there. If not than go for the pump. Its to easy not to do. I think you only have to go up to around 17psi and wait 10 min or so. Drink a beer or two and check it out.

[Zack]

Well, the leakdown tester I got from Ford didnt fit in the valve cover.

So I took a modified compression tester fitting without a check valve and pumped shop air into the cylinders one by one.

Found nothing. Basically, Im not qualified to diagnose this problem.

[Joe Walsh]

Throw on the OEM water pump just for giggles...

(I had a loose wire to my Meziere relay that was causing it to randomly shut off the electric pump.
It happened four times and my water temps would rocket up to 250 degrees!
Luckily, I caught it each time before I cooked the engine.)

OK, I just talked to zack. Had a couple ideas. The main one is with the t-stat out or even in. It may be that the elec. water pump is pumping the fluid through the radiator to fast for it to properly cool down. My friend had the same problem on his race car with the elec. water pump. His solution was drilling a hole in the center of the t-stat. I think the purchase of the water pump is a good idea. I think a larger radiator may be in order here. With a built bottom end and a twin screw it will generate alot of heat (obviously). Just my 2cents. I am probably wrong but hey, it sounds good though. I know there are alot of people that use the elec. pump on their cars but they probably dont really draw the heat like zacks does. Ya never know. If I think of anything else I will post it up.

[Zack]

Im pulling the motor Saturday.
Im gonna have the heads disassembled and Magnafluxed.

If they are bad, I have a set of heads that have been heavily ported waiting to go on.

If its the shortblock, you will see the first Carbureted Marauder next Spring.

[FordNut]

When mine was taken down the last time, the machine shop insisted on decking the block and resurfacing the heads. I understood the block (sleeve problems) but not the heads. They said it's not worth taking a chance on it.

How's your compression?

Hey zack, I think you have pulled your motor more this month than I have pulled my ----! Opps did I say that out loud? LMAO!

It doesnt need a radiator.

After talking it out with the guys at ford, we realized shop air in the cylinders might never show up as bubbles in the coolant cause its only 40-80psi.

When there is internal combustion, the pressures are far greater than 80psi.
Probably more to the tune of 200-250psi under boost and at WOT.

Its not a water pump, its not a cooling issue, its not a radiator.
Compression is getting into the coolant somehow, I will get to the bottom of it.
