[myrodr]

[WilliamS]

Thanks for the response. I've PM'd the party but haven't received a response. I have noticed a number of threads not closed although the item listed has been sold. This may be one of those cases. Just thought I would put out additional feelers.

There's someone on eBay with an ad:

Also, I know someone used a 2004 Lincoln Aviator engine when they couldn't rebuild theirs or find a replacement Marauder engine... but I would probably do that only as an absolute last resort...

Not for nothing but to spend 2400 plus 300 in shipping, i would jump onthe rebuilt engine for 3500 which a good member from here is selling.

[Ambitious1]

I would do the same. Just posting alternative options for you.

Can I ask, what happened to the original engine?

Looking to purchase rebuilt or reasonable mileage engine for 2004 MM. Thanks.

A guy local to me has one from an 04 for $1250.

[WilliamS]

Thanks for the responses everyone. The gentleman that had the engine posted for $3500 has sold it.

My greatest concern with the engine on e-bay was that the seller stated that it wouldn't start. I don't know anything else about this engine but may have to investigate further if nothing else turns up. My existing engine can be rebuilt but until I get inside and determine what is wrong, I'm not sure about being able to purchase replacement parts. Ford doesn't have many available and I can't find many aftermarket on the web. Suggestions in this area would be appreciated.

I'd consider using an engine from another vehicle but I'm not sure how it would interact with the computer. Comments on this would also be appreciated.

Lastly, Spectragod, what kind of contact info do you have on the party you mentioned?

Thanks again all. I'd appreciate any further assistance you can provide.

[RubberCtyRauder]

internal parts...bearings, pistons,crank, timing chains, rings are not ford motor company specific nor are MAF or IAC, etc..so which parts are your concern for a rebuild?

mach 1 motor can be used, aviator motor can be used, certain parts off the maraduer will be needed to be switched over..

[WilliamS]

Not having rebuilt an engine in 30+ years, I'm concerned with engine modification and auto computer interface. As long as I stick with stock parts, I don't believe I have to be concerned with this issue. I have always loved the power of the factory designed engine but wouldn't mind slightly boosting the performance if I could do so without needing to deal with computer issues.

I have considered the Mach I engine but not the aviator. Don't both of these provide lower HP than the marauder engine? I wouldn't mind a Cobra engine; but then again, I'm deviating from what the factory installed.

Your input is appreciated RubberCtyRauder.

[RubberCtyRauder]

A motor can be tuned, thru the pcm with all the new stuff in place, however there are not a ton of engine mods to be done for natural aspiration, there are some like cams, but a lot of it costs pretty big money for little gain..the best thing is a tune, long tube headers, rear end gear change to get the most out of staying "stock". A tune alone wakes up the car from factory settings and shift points that are aimed for fuel economy and not performance. The biggest performance mod is a supercharger, but you'll need $6000 for that plus a rebuilt motor before hand.

I would recommend rebuilding what you have with quality components internally and have it dyno tuned for maximum response. Maybe send a message to member martyo from MO's speed shop here in the vendor section. they know marauders from stock to high hp ones

[WilliamS]

Thank you sir. I appreciate the suggestions.

Contact will be through me. I can ship it on a pallet. Motor has 109k on it.

[RubberCtyRauder]

You never did tell us what your engine is doing, or doesn't do, did you grenade it, run it low on oil, valve clatter could just be a bent exhaust valve on number 8 cylinder which not really is common but it happens there. just wont start or? A little more info will help steer you in the right direction. Buying a used motor is always a gamble, it may run, but doe sit have issues looming, that's why if you have the funds and time, it is best to spend it once and rebuild what you have. $2k for a used motor or $2 k towards something rebuilt that has a warranty. could alwys look at jasper engines to see of they have any already done. I know nothing of jasper engines, just throwin it out there.

as info.. car-part.com has 15-20 plus aviator engines listed in the state of TX. they have the same HP, they just need certain marauder specific parts transferred over.

Spectragod is a well known member and hoarder of parts so although not his motor, he is a recommended seller.

Yupppp! You can buy with confidence!

Aviator and Mach 1 engines are the same as the Marauder engine. Valve covers (breather holes in different location), intake manifold, oil pan, oil pickup tube are main differences. Internally the same, HP the same.

My son was driving the car when it stopped. He advised that he accelerated to pass a vehicle and it downshifted as it should. As he was passing, he noticed it revving a little higher than it should have before shifting to the higher gear (he told me somewhere in low 4000's). When he got around the other car and let off the accelerator following which it was slow upshifting. When it finally did upshift, it did so really hard. He said it then began to slow down despite his increasing pressure on the accelerator. He shifted into neutral and coasted to the side of the road where the engine died. When he tried to turn it over again, it presented like a dying battery and turned over really slowly. I asked about any abnormalities on any of the gauges when it happened, any noises, or smoke. He advised nothing unusual.

I had it towed to the garage that does most of the work on this car and the owner advised they found shavings in the engine. I don't know if he found them on the dipstick, if he pulled a valve cover, etc. He figures a spun bearing but in his business it is cheaper to replace the whole engine than tear it down for overhaul. He quoted me a price for installing a refurbished engine from Jasper. The replacement engine, with exchange, was right at $4000.

A co-worker of mine that is a mechanic on his days off advised that he can rebuild the engine cheaper than the price that my shop quoted me. Since he has previously done a rebuild for me, I'm willing to let him do it. He is concerned about the availability of parts because as we look around, they don't seem to be readily available, at least for sale as marauder parts.

I can tolerate the temporary loss of my marauder while we rebuild the engine but I don't want to get inside of it and discover that I need a new crank, pistons, and rods, or a replacement head. It would be easier to spend the money on a total engine replacement with a good warranty.

This event may be an opportunity for me as my 20 y/o son and I were just talking a few months ago about locating an old chevy and rebuilding and tricking the engine as a father/son project. I sure didn't plan on doing it on my marauder though.

I know this was a long winded explanation but I hope you can see my dilemma I'm in. Replace the engine with a refurbished one with a good warranty for a steep price or roll the dice on rebuilding the old one and running the risk of not being able to locate something.

[RubberCtyRauder]

I don't know what wouldn't be avail. As I mentioned the internals are not marauder only. A cobra crank can be used. Aviator crank or any one if the engine part producers. A cobra block can be used. Cobra stuff is all over the place. If something is needed then call out here, someone here has it or knows where one is. There are ways around pretty much anything. Never seen anyone have to stop a build

[WilliamS]

Thanks for the positive responses.

Exactly... :burnout:
