Dropped Valve Seat Repair w/Pics, part deux

[a_d_a_m]

Zack blazed a trail with this thread (http://www.mercurymarauder.net/forums/showthread.php?t=67104). I followed in his foodstamps by doing it myself.

The #8 cylinder overheated because I was dumb and didn't do a cooling mod. So I had to spend today ripping it all apart. I had some help along the way (friends pictured below - plus dad stopped over) but this is largely an Adam project.

Anyway, here's the carnage.

We had a small discussion around 5pm about my timing guides/tensioners. I didn't wanna change them but I'm glad we decided to - the passenger side was actually roached. Most people never have issues with them but I apparently did (despite my usage of synthetic oils and religious changes).

Anyway, that's that. Not sure what shop I'm sending the head to or how much it'll cost or when it'll be back together...but half of the hard work is done. :D

More to come later.

[MOTOWN]

Glad you caught it before further damage happened!, wish i could have been there to help you out bud!

[a_d_a_m]

Thanks! I had Zack on standby (phone/text) and he helped when we were at a loss. Dude knows it all.

[slickster]

That's great how you have that kind of help. I need to stop doing fun mods and do some preventive stuff

Got a rear head cooling mod? hint-hint ;)

Looks ok here? Was the other tensioner arm worn? Thanks for posting pics, glad you got her back on track!

[a_d_a_m]

Getting a cooling mod from Zack (says he has some laying around) or Travis (MuscleMerc). Yeah, the tensioner arm looks good here and that's what I thought. When we peeked down over the chain with a flashlight there was metal showing. I didn't wanna do it but it was the right thing to do.

Another 5k-10k and I would have heard the 'sewing machine noise' associated with 2V guide failures. It was down to metal where the tensioner was. Would've ground it down.

[a_d_a_m]

Head is dropped off at Powerline Performance in Mentor, Ohio - will be having oversized seats installed over the next week.

Cooling mod and all the other accoutrement are going to be ordered in the next day or so...

You have one for sale?

[a_d_a_m]

Zack and Travis both have cooling mods available, as well as Dennis and maybe a couple other vendors.

[a_d_a_m]

Got the cylinder head back on (talk about a PITA with only two people - ended up getting lucky and a neighbor stopped over to help out). The chains are back on, new tensioner arms, and everything looks timed properly. Spun the engine once by hand and heard no collisions, everything felt smooth. Timing marks are all dot-to-dot.

That was yesterday.

Ran into a snag this morning. Went to torque the intake down to the heads, and one of the bolts was going in just fine. I thought it was bottomed out because I was getting resistance, but it turns out it was actually...well, I don't know. Damn thing snapped.

So instead of getting the car running today, I spent all day dicking around with EasyOuts. Couldn't get anything done with those. The bolt snapped right at deck height so I decided to try drilling it out and tapping it again. This actually worked. So, I've got a $9 unexpected expenditure on this project, the M6 tap.

Of course, this was all while I dodged raindrops in my driveway (garage is too small to do this in), leaves falling as a result of galeforce winds, etc....

Need to go get another M6 bolt for the intake to replace the one I snapped, but the lower part is on anyway. After that, I've got the following to do: plenum, throttle body, crossover tube (need to un-seize the cap in it too), alternator, power steering pump, water pump pulley, crank, serpentine belt, cooling fan, reservoir, wipers, cowl. Connect the fuel lines, injectors, and toss spark plugs back in w/coils.......

But not now. Working midnight shift and they're calling for nasty nasty weather so I've pushed the car back into my tiny garage and will resume when weather and time allows.

Since starting this project, Zack's number has gone toward the top of "most frequently called numbers". Dude got us set on the right course more than once. Damn shame he can't play here anymore........

[justbob]

Sounds like your back on the right track. Broken bolts... Story of my life! The rest always buttons up in record time. Do yourself a favor and get some new orings on the COT!

Glad to hear/see it's on the way back together Adam!

[a_d_a_m]

Do yourself a favor and get some new orings on the COT! Funny, Zack just posted that same thing on my Facebook minutes ago! Good call and will be doing so!
Is that a parts store O-ring or Ford-specific?????

[slickster]

I remember having a hard time at the dealer for that o ring but I made 2 trips to my local hardware store had one

[a_d_a_m]

Zack sent me the part number for the rings, so I'll be calling the stealer tomorrow ASAP.

[a_d_a_m]

More progress today.

First of all, I don't think I posted it yet, so here's how I keep my bolts all in one place and know where everything goes and sort of in what order. I'm really not a fan of bagging or taping everything. This system, in my opinion, is superior for a shadetree mechanic like myself who really doesn't know what he's doing:
https://sphotos-a.xx.fbcdn.net/hphotos-snc7/306566_740231268831_187146077_ n.jpg

Got the following done today: plenum, throttle body linkage, throttle body, plugs, coils, coil covers, EGR, vacuum lines, injectors plugged in, random electrical connectors hooked up (no idea what they do!), alternator placed and mostly mounted (aside from the bolts on the top where the crossover tube goes).

This is what it looks like now:
https://sphotos-a.xx.fbcdn.net/hphotos-ash4/384180_740231263841_986459154_ n.jpg

Still need to figure out how to unseize the crossover tube plug (gonna try heat since I actually broke my new 1/4" ratchet!), then install new O-rings on the tube. Those are the big projects. After that, I'll do the water pump pulley, crank pulley, 3 PS bolts (it's currently held on by the one impossible bolt that's above the PS line), electric fan, reservoir, PS reservoir.

After that, just a few little plumbing things like burping the coolant, hooking up the fuel line, and it should be ready to fire.

[vegasmarauder]

To unseize the plug this is what worked for me (and for other rusted bolts). I mix up 50/50 Acetone (from Home Depot) and Mercon V transmission fluid. Find a container that the acetone won't eat through such as an old hair dye bottle (I went and bought a hair dye kit and just used the plastic bottle). Wet the seam where the cap fits to the tube. Wait 24 hours and wet it again. This time place the edge of the plug against something metal like a vise (if still on the car, use a body work metal dolly) and tap the opposite side lightly with a hammer. Don't need to beat it up, just tap it. Move around the whole edge doing that. The plug should come loose then.

Put a tiny amount of anti-seize on the thread portion only. And, Always, always, always change the o-ring on the plug. If not, it will leak and you will be tempted to tighten it some more, thus creating the problem again. The plugs with a new o-ring don't need to be super tight to seal. Oh, yeah, make sure the surface in the tube the o-ring seals against is clean as well.

I have had to do several Lincoln Continentals with 32V engines and MM's and this has worked (even one another mechanic broke a 1/4 drive ratchet head in the hole and chewed up the edges using a hammer and chisel to try and get the plug out. Soaked it, tapped on it, and unscrewed it with vise grips.

Good luck..

[a_d_a_m]

Thanks for the tips. I am going to try just a little heat and see what happens.

After that, Zack suggested welding a nut to the top of the crossover, and then hit it with impact.

[a_d_a_m]

Not much progress today. Woke up after working midnight shift and tackled the crossover, unsticking the plug, cleaning it up, and installing new O-rings. All it took was a little bit of heat, after all.

The next few things require the car to be pushed into the driveway, so I'm gonna wait until Sunday when the weather's supposed to be actually decent to do that. Hoping to fire it up Sunday or Monday.

[MOTOWN]

Sweeeet bud! think of all that cash you saved your self!

[a_d_a_m]

Oh trust me, I know. As long as I can start it and it runs like it's supposed to...that'll be extra scratch in my wallet to pay bills! (and maybe buy a couple fun things)

[justbob]

Looking back at your pics, please don't tell me you forgot to reinstall the tensioner forced kinetic pins...

After forgetting to hook up the crank sensor and a couple vacuum lines, I finally got her FIRED UP! So much powah (https://www.facebook.com/photo.php?v=740747130041) it knocked the camera over!

Big congrats on a job well done man!

Thanks Bob!

[Vortech347]

I dig your bolt organize idea. I usually use zip lock bags but yours looks harder to loose mid project in the garage!

[a_d_a_m]

The other benefit to doing it this way, is that if you just go in a numerical order, you have a very clear idea of what order to work backwards in!

Thanks!

[pantheroc]

Good job Adam! Too bad your not closer, I could have done a lot of learning.

[a_d_a_m]

You would have heard a lot of cussing!
