What is the plan for the roof?

Rich



Roof will be done at a later date. For now it ( the bus ) will go back to the house until Mike is ready to put the engine in. That way he can drive it with the fixed roof so I can get the 914 done, make some $$$ and prepare myself for the roof " project " It really won't be that bad I just need to get some other things out of the way first, and he can enjoy the bus sooner.

Besides that, it clashes with all the little Italian red....
Cool job, get Mike to finish up that motor...we are having a spring thaw today...

NICE! That is great man! Did you put the glass in or did you get that guy to come and do it?

RE the engine: I got the lower end started tonight. The case halves are together with the crank and cam, and the bellhousing is installed. The crank moves free and all looks to be going well. I have it mounted on the stand. I cant wait until tomorrow to do some more (IMG:style_emoticons/default/smile.gif) Gonna CC the heads.


I want the bus to drive to Hershey (IMG:style_emoticons/default/thumb3d.gif)

I did it. I couldn't remember who the hell it was. I went by the Old Volks home, because I thought for sure it was him, he said it wasn't. Aren helped with the back hatch and the jealouse windows. I got the two side rears by myself. It was a lot easier then it sounds. Fuch those jealouse windows though. Never again for this white boy (IMG:style_emoticons/default/dry.gif)

Tonight I finished the piston balancing and started fooling with the heads. The pistons had a range of 4g and took some work to get within 1g of each other. I did it because I wanted to, not because it needed it. Its not like I am racing this bus. (IMG:style_emoticons/default/wink.gif) What was a PITA was that the pistons come with the rings already installed and I had to take them all off, but it was easy and I didnt break any...yet.

I started smoothing out the heads tonight as well. Since the heads have been opened up to accept the wider jugs I am left with a nice step with a sharp edge to possibly cause preignition. I took a dremel and sanding wheel and gently smoothed these surfaces finishing up with some sand paper. It is looking good (IMG:style_emoticons/default/smile.gif) I was smart and had the top of one of my spare cylinders that was damaged in shipping cut off so I could use it to protect the seating surface while I sand. One head done and one to go. I need to pick up some small files so I can deflash the head fins. I though I had a set, but I cant find them and they are $3 at Harbor Freight. It is possible that this will be mostly together by the end of the week (IMG:style_emoticons/default/smile.gif)

CRAP! So, I was cleaning up my cylinders and pistons to put them on the engine and get a final read on the deck height when I noticed that the cylinder that I previously dropped was damaged more than I originally thought (IMG:style_emoticons/default/sad.gif) I thought I just chipped the skirt, but on closer inspection the whole base had a crack that was hard to see. Looks like I will need a new cylinder....and to have it worked (IMG:style_emoticons/default/dry.gif) Just another set back, at least it is a minor one and I found it in time.

Got the rod bearing in today and installed. Still waiting on the replacement cylinder so I can get it machined, then it is time to assemble. I have been working the heads today; deflashing the fins and passages, smoothing sharp edges in the chambers, and CCing the heads. Almost done with the heads.

I need to start adding pics so people wont be so board with this thread (IMG:style_emoticons/default/wink.gif)

All sounds pretty cool Doc! A rebuild on the "other" air cooled -6....

You might give a quick email to Steve at Rear Engine Specialists to see what "licks" he'd recommend on doing a home port-job on the heads (and any other recommendations he might give overall). Steve's a super nice guy and been into those engines for a long... long.... time.

Now show us some pics!! Are you staying with the Rochesters? or going 4bbl? Headers?

FWIW, Steve put this beauty together:

Hey Jeff,
I am going 4bbl with electrically adjustable jets. I am also running headers. I am not juicing this thing as much as possible, I am actually keeping the CR to 7.2-7.4:1 so I can run low octane and still get enough oomph out of the engine. I also am using some worked over old style 80hp heads that have extra intake ports added (came that way) and stainless valves. I'll get some pics in a few days....I am going to be at Zachs for most of the weekend working on his 914.

That is the first time I have seen the Corvair intake manifold. Two runners into the manifold then three intake ports. Doesn't look very efficient. One question: Why did they do that? (IMG:style_emoticons/default/confused24.gif)

I think I've heard that people cut off the manifold to fit triple throat Webers. From Jeffs phot it looks like you could fit a dual throat Weber if you had a suitable manifold. (IMG:style_emoticons/default/idea.gif)

And that engine case sure looks different form a VW/Porsche case. Very square looking. Interesting.

Hi Guys,

I thought I would throw in some Corvair pictures I took back in March 2005 just before they sent all this stuff to the dumpster. It's gone!! (IMG:style_emoticons/default/mad.gif)

I had a bored 140 with 3bbl 40ida weber carbs custom headers, roller rockers all the OTTO stuff bla bla . It took 2 years to finally sell it to someone back east. If you look at corvair heads funny the seats will fall out.
Gone but not forgotten, fun cheap cars in the late 70's.

Corvair motors with auto transmissions find their way into strange places. (IMG:style_emoticons/default/driving.gif)

140 heads have seat problems, similar to our 2.0 heads and for the same reason, not much metal between the valve seats. There are many fixes, mainly you just need to install the seats correctly with .030 crush for one. I chose the 110 heads because I wanted low end, off the line, and less worry about dropping seats. I actually am using 80hp heads, but the valves are the same and I have done some chamber tweaking. I have not spent too much on this and can do upgrades later if I want.

My first engine I was doing like this for a 914 got to kit stage with all the parts, it sold easily and I made money.

The heads are the week link without a doubt, but they can be worked pretty easily. They cant be too bad, they are coveted and used in home built planes often.
