I think I lost a p[lug yesterday. I'm not sure sence I haven't opened anything up yet.
I was comming to a top after a moderate 3/4 throughtal run, and heard two matalic sounds. I thought I ran over something, but then my engine shut down.
It turns over with no wierd sounds but when it catches it is rough, and won't stay running. I hope to open her up tonight and find the issue.
Anything I should look for?
30,000 Hard and vicious miles, and this is the first problem on this rebuild.
Hopefully it is nothing major.
It sounds like you lost a chain. Oh my God, I hope this has not happened to you. You of all people know my story.

Man, Phil that sucks...I hope it doesn't turn out to be too serious, but from what I read here..:gulp: Keep us informed.
Say Hello to Tasha from us. We miss you guys. :cry:

Make sure there were no Glocks in your car. They have a tendency to go off without any reason due to the lack of an external safety. :pimp:

This does not sound good at all ... especially after reviewing Merc's thread from July 2003. :( Here is hoping for the best for Phil, Tasha, and your MM. :D

Ok...Moving right along... Seems like a timing chain maybe? I hope its not to
expensive, unless you still have your Warranty. Good luck :depress:

Sounds like operator error to me,....I have seven of them and have NEVER had a problem, with multiple INTERNAL safeties.

The subject is about a engine failure, not about gun safety. Start another tread about this subject, don't highjack this one.

Isn't the 4.6 4V V8 an interference engine? If your chain/cam gear broke, your valves and pistons are FUBAR'd. Check there first if you think its the cam gear(s) and or chains. This isn't some 4-banger that can run w/o a timing belt (non interference engine).
I was making a joke about Glocks. Sigh, no sense of humor. :beer: For the anti-gun folks here, mention "Boom" or "KaBoom" on a gun site and you'll get a few dozen snide remarks or comments about the Glock. Thread unhijacked. :bandit:
".......on this rebuild". Do I understand correctly that this engine has been rebuilt before (or replaced)?

Oh yeah. I fried the motor at 8k miles due to a wrench not installing the Harmonic ballancer on some underdriver pullys. Long story, not going to retell it here.
Early diag so far.
I am working with about 30-45 min of light and it was cold and wet whenm I got home, so I only got the spark plugs out of the passanger side. They were still good with only a little red on them from the crap in the gas. I will be trying to get the drivers side plugs today.

Not a lack of a sence of humor, or an unappriciation of supioror firepower. This is the secound time I've had major issues. The first resulted in a complete rebuild. I had resorces at that time I could draw apon to get the work done. This time...
I may be well and truly :censor:

Your new engine was a 5.0 stroker, correct?

Yes, when it blew the first time we had it stroked to 5 liters by VT Engines in Michigan.

When it runs are there any off sounds before it shuts down? lick a clicking or the like... Same sorta thing happened to me, cept I was on the freeway. I hope your problem is nothing like mine :(
Since VT rebuilt it and stroked it, do they offer any kind of warranty with their engines?

Aftyer 30,000 miles and almost 3 years, I think it's expired.
Yes, to answer your question 10k and 1 year I belive.

When I shut down my motor (granted it is a 4.6 2V V8 and not a 4V V8), it makes some clicking noises. I think its just the camshaft continuing to spin from intertia and the oil pressure/compression dissipating.
"Click click WHRRR PFSSSSSSSSSSSSSH"
I don't hear it on the 5.4L V8 as well but I did hear it on the 4.6 before I did the cams.

The cams are mechanically connected to the crank.

The cams are mechanically connected to the crank.
Not directly linked. There is a chain for each cam gear/crank gear set that has some slack when the tensioners lose pressure.
Right at TDC my RH crank will "jump" if unsupported because the lobes are at a weird point where if you touched it on either side it would roll a few degrees. I can't explain it well, but when I pulled the motor you could tell very easily (even with the stock cams) that the RH cam does that. The click-click-whirrr-PFSSSSSSSSSSSH is reported to be normal on some Mustang GTs (pre-3V).
CROWN VIC TIMING CHAIN NOISE
A case in point is grinding noise coming from the timing chain cover area in 2000 to 2003 Ford Crown Victoria and Mercury Grand Marquis with the 4.6L V8. According to Ford Technical Service Bulletin 03-15-7, excessive wear in the timing chain tensioner arms can cause a noisy condition. The tension arm has an aluminum base with a nylon surface. So if you find nylon and/or aluminum particles in the engine oil, it probably means the tensioner, tensioner arms, timing chains and gear set all need to be replaced. The Ford part numbers for the 2000 model year tensioners are F6AZ-6L266-DA (RH) and F6AZ-6L266-CA (LH). For the 2001 to 2003 model years, the tensioner part numbers are 1L3Z-6L266-AA (RH) and XL1Z-6L266-AA (LH). The tension arms are 1L2Z-6L253-AA (RH) 1L2Z-6L253-AA (LH).
Ford also recommends changing the oil and filter to flush any nylon and aluminum particles from the crankcase. If the timing chain has worn through the tensioner arm into the tensioner piston, remove the oil pan from the engine and clean the debris from the oil pickup tube.
TIMING CHAIN TIPS
When replacing a timing chain on any Ford engine, always replace the chain, camshaft and crankshaft sprockets. Don't reuse the old sprockets to save time or money. All three components wear as a system and should be replaced as a matched three-piece set. Some OHC kits also include chain guides and/or tensioners. These "extra" parts play a vital role in supporting the chain and keeping it tight and should also be replaced at the same time.

Ok, anyone local to me have a copy of the Fast Ford Muscle Mustangs where they did a cam swap on a DOHC? I had it, but I resently cleaned up, and trashed it. (figures)

Give me the month. I think I still have my issues from the last two years... well till I let my sub run out in June.

If you think you might what to replace the cams you may need this tool set.
