What gaskets are on those TMH?

I hope it's Ultra Copper. How good are the flanges, the fit? If it's perfect, Ultra Copper may be the best solution, it works on headers with great flanges.
 






I had copper gaskets on my TMH and then switched to the percy's / mr gasket style sandwiched aluminum they seal better
The coppers still had leaks.........TMH have been very difficult to get to seal up over the years. I think I am finally winning
 






I used the gaskets that came with the OBX's. Also the only hardware that is included is the EGR tube and the two bolts and nuts to attach the two parts of the driver's side header. There are NO manifold bolts or collector bolts included. Fortunately Kris had a set lying around for use on his extra set of TM's that worked perfectly. They are a PITA to get on, fortunately I didn't have to put them on INSIDE the engine bay. :wtf:

What is a little maddening is that this engine has been through 3 intake manifolds. First one an upper intake bolt broke off in it last year during diagnosis, the second had the wrong bolt put in the fuel rail tab and it snapped off in that one too. (too long, found out it was the same bolt that is used for the CPS, :banghead:), tried to use an EZ out but it just wound up splitting the boss. Fortunately Kris had another spare in his cavernous shed of Explorer parts (I'm not kidding, they have a whole 50 foot cargo container full of parts. There is so much in there they even they don't know what they have!) so out came the old one and I de-greased and painted the new one.

If there is anything I have learned from this whole debacle is that you must LABEL EVERYTHING!! (kind of have that playing in my head like the Nero character in the Star Trek movie reboot, "FIRE EVERYTHING!!". Yes I am a total geek :D)

A hell of a lot of time was wasted finding the right bolts and parts in my giant bin labeled "Engine Stuff". Another big time sink is parts prep (clean, wire brush and paint). I spent hours doing that to nearly every bolt, bracket and part you see in the pics.

I should have had everything vatted and powder coated...well at least vatted, powder coating is expensive!

I am heading back up there this weekend to finish the install. I broke some vacuum lines on removal that I needed to replace and I still have to install the upper intake and get a battery. Then this beast will roar to life... or I will send a rod into space. Either way it will be worth the memory used in the video. :laugh:
 






I wish I had more progress, but every time I get close another problem pops up. Plus whenever I get a weekend to work on him I have to drive to Austin. I have almost 2000 miles on Stripe just from going up there and back working on this build.

Anyway, I'm looking at the end of January for completion, but the next time I'm up there he will fire up!
 






............................................................. end of January is almost here!
Running yet? LOL

I wish I could have a 40' high cube shipping container for all my parts!!
 






Sooo, ran into a snag. This thing is backfiring under load and has no power. Current thinking is the computer can't adjust the timing enough to compensate for the cam. Russell is bring over his IDS to check what the ECU is doing. Also getting lean codes on both banks. :dunno:

What are the main engine details again? What is the compression, the cam @.050 duration, lift, and how was the valvetrain set up(bolt down stock rockers etc)? Something may be amiss and it not be the PCM.
 












Standard compression, bored .030 over.

Cam specs: Xtreme Energy Computer Controlled 212/218 Hydraulic Roller Cam for Ford 5.0L

Stock rockers, .630 pushrods vs stock .625, dual valve springs.

That sounds mild enough and reasonable. I'd say something isn't put together quite right, the distributor, the timing chain, some electrical connector, plug wires, or even a vacuum leak etc.

How did you install the cam synchronizer, the process of setting TDC on #1 compression stroke etc? That's a real easy thing to get one tooth off, and creates all kinds of odd firing issues. I suggest pulling the #1 plug, rotating the crank to the balancer TDC line, and checking with the alignment tool, and that air blows out of the #1 cylinder right then(at that TDC).
 






After the IDS was hooked up, it appears the timing is all over the place, between 12-30° during idle and operation. Have an EGR fault as well (P401), but that seems to deal with a bad DPFE more than anything (was present before the engine rebuild as well) and shouldn't be causing lean codes.

Very frustrating. :banghead:

I'm also dealing with a mysterious oil leak right over the driver's side cat. Could be the rear main seal, but that was replaced and so was the oil pan gasket. Even more frustrating. :censored:

And I'm not going to be back in Austin for a little bit, so I can't spend time diagnosing the issue.

Grrrrr..... :rant:

It's hard to take solace in the fact that the engine is running when it's running like crap because of something you may have screwed up.

On the lighter side, here is a few pics of the fully installed engine. Engine running video is on Facebook

have you checked fuel pressure? backfiring and bucking under load is lean
SOB I hate to hear this stuff.. hopefully it is something easily fixed.
I am not sure about your oil leak, that is scary, it could require removal of the engine or trans if its the RMS

Kris and Russell are going to do some diagnosis when they have the time. I'm wondering if the oil leak might be from the dipstick tube? I really had to bend it to get the bracket to fit on the header bolt and since it has no seal per say (I did put RTV on it) it might have come unseated during install. :dunno:

Well its better than a leak from the oil pan, that will be a real b!tch to fix. o_O
 






There is a small oil ring on some dipsticks, I have seen them with and without. You could add one to any of them though. RTV usually seals it if you get enough on it(and could be hell to remove).
 






I use RTV on the dipstick also with a small O ring
That could easily be your leak

The PCM should be able to run your engine without a miss, even with the 306 displacement and the mild cam
The PCM's can compensate for quite a bit from sea level to 11,000, from 85 octane to 93, mild boost, large cam's, etc they all still run smoothly until the tune can be done.
Misfire through the intake and struggling under load = lean
check your fuel pressure SPARK PLUG routing, and fuel line plumbing
 






The engine has a serious lope, quite a bit more than I was expecting from a mild cam. Sounds like one of those professional drag engines at idle. At 2000 RPM you can set your beer can on it and not see any movement, smooth as silk. Put a load on it and it gets really unhappy.

Hope Kris and Russell can provide some answers... I hate being almost 200 miles away from my project. :frown:
 






The fuel pressure is a good place to start, that's easy to check and shouldn't be hard to fix, if it is low. Fingers crossed,
 






Talked with Comp Cams today. They had no insight into the issue other than stating that this cam should not be causing the computer to advance the timing that much since it is pretty mild.
 






the computer has no idea where to set things at, it is in learn mode since it was just connected for the first time. Without proper fuel pressure or a smooth base idle it cannot learn what fuel/air/spark curves to work from upon initial startup.
Bucking and backfiring is a lean condition, worry about that situation first and I bet the timing issues go away.........

If all goes well I am heading back up there this weekend to do the diagnostics. This is driving me nuts.

I am a very hands on guy and being disconnected from the situation with all these hypothesis to check out is making me very frustrated. :banghead:

(Breathe in... breathe out... think happy thoughts.) :cool:
