Blown

[FastMerc]

Well the supposedly bullet proof stroker motor broke goes to the shop Monday to see what happen. Just driving home and started knocking loud. I am wondering if the bad gas in Arizona may have weakened something? Any way wish me luck. :o:mad:

[1stMerc]

Good luck with her...

[RubberCtyRauder]

Sorry to hear Mark. Hope it's maybe just a valve seat or something

[1Marauder]

Sad to hear. Best of luck.

[martyo]

Dammit Man!

Let us know what happens!!

[justbob]

Sorry to hear Mark.

Ugh :(

Sorry to hear :bigcry:

[vkirkend]

Sorry to hear that Mark...Hope it's nothing serious....

[Merc-O-matic]

Mark,
Keep us updated.....thanks.

[FastMerc]

Thanks for all the wishes guys. I think that **** ethanol gas coming cross country may have been the reason not sure though.

[a_d_a_m]

That sucks, but at least it went sour when it was about to go off the road for the winter anyway.

[RF Overlord]

I think that **** ethanol gas coming cross country may have been the reason not sure though.As long as the octane was sufficient, the presence of ethanol shouldn't matter to the engine. Here in MA, we've had E10 for at least 10 years and don't hear of engines failing.

I'm sorry it happened to you, Mark...yours is one of the best-sounding (and looking) engines around.

I have 190K miles and over 280 1/4 miles passes with no "Bad Gas".

For a few weeks after Katrina we had gas quality issues.

I have driven the MM all over the Gulf South.

I wonder how many performance built engines are actually "blown" due to bad gas?

How difficult would it be to have a sample drawn from your tank and tested?

And if it proves to be I'd file a claim on auto insurance.

Good time for boost no? :D

[Mr. Man]

Bummer dude :bigcry: Hope it's a cheap and easy fix.

The highest octane pump gas in Vegas is 91. But I add 2 gallons of 100 octane every couple tank fulls to spike it

they never are..............

[FastMerc]

I have a update. There test tell them 8 cylinder low compression and a rod bearing spun. So the tear down begins.

[FastMerc]

Got the news today saw my motor, a valve spring broke and bent a valve and broke a valve guide and scoring in the cylinder. May need a new head not sure yet. So I am guessing hi at around 8,000 to repair it :(

[Comin' in Hot]

That sucks, but for 8k, I'd be leaning towards a coyote swap or the new ford racing 5.3 short block.

I got burned by a junk Modmax valve spring breaking about 8 years ago on a new motor, just a NA 2V in a Crown Vic.

I don't know what brand of valve springs you ran, but I have become rather cynical about aftermarket parts. They don't get anywhere near the testing and proof of reliability that factory parts do. I will think very carefully about what parts are replaced with aftermarket when I rebuild the current engine for supercharged duty.

Obviously rods and pistons can't remain stock, but there are some brands that have a good track record. Oil pump and valve springs? Those could possibly remain stock, with perhaps a replacement of the powdered metal pump gear only.

Well this motor was to be a bullet proof 5.0 stroker!

[lifespeed]

Guaranteed not to blow up, or you get to buy a new one!

Sorry to hear of your motor disaster.

Who built it and where did ya get the parts from.......

[FastMerc]

Alternative auto Lidio did the motor 4 yrs ago.

[a_d_a_m]

Prior to Vegas, you hadn't done many miles on that motor, either, right?

[FastMerc]

Less than 30,000 miles

[a_d_a_m]

Wow...just, wow!

[sailsmen]

Thats more than I paid for my Ford Reman Long Block. Get another estimate.
Heck, buy a whole Marauder.

That motor would be going backwards for Mark. His engine is far from stock

[FastMerc]

I am assuming I would need new headers, so that's a no.

[FastMerc]

Well got my ouch! Total cost of repair and rebuild is 9200 bucks. Should have it back in a couple weeks.

[03blackvegas]

Is Gaudin doing all the work?

[Mr. Man]

Good thing your in Vegas Mark. Now go turn that $1 into 10,000 ;)

[FastMerc]

No they sent it to a speed shop to be repaired, suppose to be number one shop in town.

And you agreed to this price???

LMMFAO!!!!!

[sailsmen]

Ship it to Lidio for examination and to determine the cause.

If you don't determine the cause and remedy it pop goes the weasel.

I am very sceptical of all these engines blowing from bad gas. If it is bad gas you should be able to pursue a claim against the gas station.

[vkirkend]

Mark, sorry to hear this, hopefully she comes back better than ever!

I have no choice im new here and time is short!

Wish I could have but all my tools are back in Ohio. The prob was a valve spring broke.
What gas station all of them in the southwest have **** gas. But atleast I can get 100 octane here to mix it.

Was it a first generation spring from Livernois?
If so, you are not the only one.
a LOT of mod motors have paid the ultimate price for their garbage springs.

hotford on here lost an entire engine.
I had one break on me in my Cobra, but luckily the valve did not fall.

100% true..............

100% true..............

Whew... I used comp cams beehive springs.

A broken valve spring certainly is not bad gas. And those members engines that did fail with detonation symptoms like a broken piston or ring land it is debatable what the true cause is. It could be a marginal tune, marginal ring end gap clearance or piston strength. When you supercharge a cast-piston motor that was not designed for a supercharger you are running on the edge. Everything must be perfect: tune, fuel octane, etc.

Lidio built Marks motor and it is not supercharged

I was commenting on the whole "bad gas" thing, not Marks' motor. Hence the quote for context.

[FastMerc]

I talked to Lidio and clued him in and he was surprised to here that. He used Crower components.

[Comin' in Hot]

Ford Racing's 5.3 short block is based of 4.6 architecture so your headers will fit.

Don't need one lol...
