Steve could hear the noise just by listening near his wheel well.


Steve could hear the noise just by bloody standing in the driveway within 30 feet of the lousy car! :D

The "wheel well" reference is due to the fact it seemed to be coming from there. But make no mistake about it, it was audible from anywhere outside the car.

This 4V DOHC is almost a Hemi, and it should be treated like the Hemi of the late '60s. Beat it to death, it runs better. Carbon deposits are a death sentence, this engine loves hard work at high RPMs...IMHO.


No doubt about it, these engines love to run hard and high. But a 60s Hemi is a 60s Hemi... modern engines don't carbon up that quick without having an oil-burning issue as a root cause.

If there's one thing this whole experience has proven to me, it's that the CRD1 PCM software does NOT have a plug fouling issue on its own. They all looked nice and the technician confirmed they were to his satisfaction.
 
The carbon buildup patterns on the piston, proving the rings are fine (it's not a circular carbon pattern) and that the oil deposits were coming from valve action.

The offending valve guides. The exhaust ones (on the right) were the worst, exhibiting signs of heat damage. Valve stem play within the guide was VERY noticeable, and was the direct cause of the ticking.

Nice spark plugs running on CRD1 PCM s/w. This is the front driver's side cylinder.

Yes, it's not a Hemi. Seems I misunderstood your want for 411.

BTW...Sorry to hear your laid up.

The Cobra and the Marauder don't share the same heads so I don't think the Cobra problem pertains to the Marauder. RAY


Can you confirm this?
 
TTA,

My Marauder was the first Ford that I've ever had also. I have to admit that I'm disapointed with the car in general. Until I modifed it, it wasn't close to my Impala SS's ('95 and '96). In stock form, the Impala blows it away (IMHO). The unfortunate thing is, to get the car to perform the way that it should, you risk, and really void, your warranty. My car is a very early build (purchased 6/02), and I have the ticking sound also. My chip does not fix my cold start hesitations (brief, but still there), or the rough idle. (I'm sill looking through the code). Dealer's are clueless about this car. I think that more tranny problems will surface for people as well, as time goes by. If I wouldn't take such a bath on selling it, I really would most likely sell it. Sorry for the negative comments, but it is just the way I feel about the car (maybe it's just my diehard Chevy upbringing ;) .

just my .02

I've got to agree with Sarge here. The engines are similar but not excatly the same. I ran my '99 Cobra to 100K prior to trading it. The only time it was every taken apart was when Ford replaced the intake manifold and exhaust under the low horsepower issue. Otherwise, the engine was never touched. Oil and filter were changed every 5K as it was a daily road runner. It wasn't beaten to death, but it was dirven hard. The same holds true for my MM. It's not beaten to death, but it's a daily road runner. The MM has added mods the Cobra didn't have. Chip.plugs,gears, and soon to be installed MMDS. The only mods the Cobra had was a WMS 80MM MAF, and K&N thru the fender cold air kit. The Cobra still had the orginial brake pads, and clutch when traded at 100K. The MM now has 34.3K, and running strong and true.
 
What's reassuring about all this is that I really did want feedback on whether I did anything wrong with the car. Too many attempts at breaking the tires loose? Too many 5000 RPM romps? Too many highway speed downshifts?

My technician, who I am beginning to trust blindly with the way he has been a superstar, seems super confident that these motors can take the abuse. He says they should be able to rev to the sky (seems to jive with what was described in a Mustang dyno pull in another much earlier thread). To get this kind of confirmation from someone I respect to this degree, is enough to keep my MM interest level high. I'm also beginning to feel confident with some future 'bullet-proofing' modifications as far as this dealer goes...

Just a bummer that we, as dedicated and enthusiastic owners, have to be the ones to suffer along with the car's growing pains. A 'parts bin' car indeed, but if this was truly the case one would expect the reliability to be equal to the lowest common denominator among those parts. Instead, we have ticking motors, desintegrating transmissions, popping suspensions and alignment problems, and harness issues. The company needs to wake up and see where its company stock value is headed... and why...



Anyways, on a positive note: the car should be back together by mid next week, under a very very interesting approach that might suit me just fine. Be certain I will post all the details if this works out, because I'm sure it will benefit all of us tickers greatly, but for now I'll have to see how things work out.

Because of the great information from Steve on this sig I started my cold MM today and watched the tail pipes, yes a big puff of blue smoke rolled out of the pipes for about 15 seconds then stopped.

So I went to my local F/M dealer today and explained my ticking sound and cold smoking problem to the salesman. I also mentioned the silent recall on 2003 Cobra valve guides which we was aware of, so we went to their Parts Department to see if the 2003 Cobra and MM share the same valve guide part number and they do! P/N F5AZ-6510-A. Damn!

So my MM is going to the shop on Tuesday for compression test!
 
I didn't want to let the cat out of the bag yesterday responding to the post about the heads being the same... someone claimed the heads were not the same as the Cobras. The parts list does not reflect this... so, I won't say anymore except "you figure out the rest".

Bill, your compression check will probably come out A-ok. The problem isn't (or shouldn't be) with the rings or valve seats, it's the guides. These are "out of the picture" once the valves are closed and things are being compressed (unless the guide has worn so bad that the valve won't seat properly, but that would be REALLY nasty).

If you'll wait a half-week or so, I should be able to report some interesting options for those of us with smoky startups and ticking driver's sides. Until then, I'm bound by a promise to keep quiet in case this leads to a dead end (which I don't believe will be the case).
 
sounds like we might have a good excuse to mod the heads without penalty to the waranty. :banana2:
 
Ticking and smoking MMs

Thanks Steve I'll be waiting for your reply!

Steve I pulled my Denso plugs today and all they looked great except cylinder #7. The cylinder on the drivers side closest to the firewall. This Denso plug looked wet and black. So I put my old stock Motorcraft plugs back in, (all 8), and started it cold again like yesterday.

Guess what, no smoke coming from the tail pipes at all!

Engine ran very smooth!

I wonder if maybe the #7 Denso plug is bad since it smoked yesterday with them and not with the stock Motorcraft plug today?

Maybe since #7 is getting excessive oil from the bad valve guide it caused the Denso to fail?

Any suggestions?

Thanks!

#7 plug, eh? Coincidence? hmm..... ;)

I'd be inclined to recommend you keep a watch on that spark plug and any puffs of smoke on startup. Did your ticking go away after the spark plug change?
