Need Massive Help, Case failure Options

[Bills914-4]

Damn, so sorry Mike , you have alot of work in that case , timeserts, bore for 102's,
shuffle pins, ect, , I might try and save it , I would put a correct dia. (cam bearing o.d.)
bar in the cam bore , v-out the crack inside ,pull the piece back against the bar with
small clamp gently , Weld the outside crack let it cool ,remove clamp & bar , then
weld the v-grooved crack , once it's cooled dremel down the weld , check it by
sliding the Bar back towards the welded cam saddle seeing if the bar stops , using
it as a gage , clearance it until it slides in smoothly , then assemble the case with
cam+bearings only , torque it down little by little checking for cam binding by tuning
the cam , then mill file the parting surface to match , just another idea Bill D.

ps you can hold the bar in the cam saddles with a couple of straps going thru
the cylinder bores and around a wood 2x2 ,

I would repair it if it was mine.
Careful build-up with TIG, no use trying to weld the broken bit back on. Then hand grind/file/scrape until a custom made gauge pin barely fit through the bore - always being careful to not cut into the remaining original bore surface nearby.
I wouldn't use a reamer - too much chance of removing material from the other case half.
1 hour for the weld process and another 3-4 hours of hand work.
Tedious, but doable and worth it to recover the investment.

That is the way to go. It is not the end of the world.

Sometimes we expect too much of an old thing. Please don't dump any huge money after bad. Are you insistent on TIV? If so, trust Chris.

[Mblizzard]

All good advice. But I think I am going to see if I can get another case opened for the 102s and uild from there.

I am also going to have this case fixed and build a backup engine.

Crap I hope someone can complete the case quickly.

George I may be calling you to get some recommendations.

After looking at things for a long time I think that when the crank broke it sent a lot of shock to the cam and stressed this rea. New bearings and can’t just stressed the area and it failed.

Really have to pull one out of May ass to make it by Okteenerfest.

Mike - I know you really really want to get your engine done in time for Octeenerfest but I would look at plan B. Building an engine on a short deadline is never a good idea, especially when it's a custom build. Take your time, enjoy the build and enjoy Octeenerfest.

(IMG:style_emoticons/default/agree.gif) a replacement case is the least expensive component at this point. A failure could be catastrophic. Would it be in the back of your mind every time you drove the car?

[porschetub]

Now that is sh#t luck after all you have been through,as an engineer I wouldn't even go for a repair on that case its a real gamble to get it 100%,well at least 914 cases are cheap but that helps little considering the machining work that has gone into that one.
I haven't done a T4 build for a while but currently doing one and TBO its not what you call cheap,have better luck mate (IMG:style_emoticons/default/beerchug.gif)

[Mblizzard]

Any suggestions on who could bore out the case to 102 quickly?

[Mark Henry]

You don't need to timesert the case headstuds threads, I've never had an issue. but you should get a thread reforming tap to run through them before installing the ARP studs. My case isn't shuffle pined as well.
Only issue I've had is leaking ARP case through bolts, I recommend a good sealant under the washers like threebond (Yamabond4) or loctite 5900.

As for making the show, give it a go but there will be other shows. Last thing you want is a fuch up because you rushed through things.

Metal craftsmen with the required tools and skills aren't too common nowadays I suppose.
Someone who restores antique cars maybe? An old machine shop that also does welding?
Someone who likes to work with his hands and has plenty of patience.
If its going to be a back-up and you don't mind waiting a few months, you can send it to me.

@mblizzard

Mike, I would contact George at European Motorworks in Hawthorne CA.
He had over 300 cases there. He has been building Type Iv motors for decades and is reasonable. Could probably get you a case of send all the long block guts to him and have him build it. He did a 2056cc long block for me years ago for $300 assemble including balancing. Motor still pulling 6500rpms on a tracked car.

That’s an easy choice. I will send it to you!

I second the Jorge recommendation if you need it quickly.

He does fast turnaround.

Ok so now I am trying to find someone that can open up my case for the 102's this week.

Looks like Len can do it! (IMG:style_emoticons/default/smile.gif)

Packing it up and sending to him!

So is Len fixing it or are you sending him a different case to start over with?

Something else, I wouldn't rush an engine build. When I put a 78mm crank in my case I must have assembled and disassembled ten times to check all clearances. Taking your time will pay off in the end. (IMG:style_emoticons/default/biggrin.gif)

Starting over on new case. Will likely send to Chris at some point to look at fixing.

What crank are you using?

78mm from Type 4 store. The assembly and disassembly is exactly what I did on the first go. There were very few clearance issues.
