Rob's Blue Bus

1. No, 1800 cylinders won't fit into 1700 OEM heads.
2. 90mm flat tops will be fine if you set up the CR and the Deck Ht correctly.
3. You could do this if the pistons/cylinders are still with in spec and aren't worn out.

My concern is the amount of miles on the main and rod bearings. Slapping on new P&C's and heads on tired bearings isn't a great idea.

Financially it's not an option. I may have to move from my home this year. Obama has been reaching DEEP for a while and I don't know how much longer I can keep my head above water.
I purchased the engine from Manfred in Chicago (IIRC) and was told the engine ran great. One of the heads had a broken exhaust stud I never noticed before, hence the reason for the head swap.
I still have the original 1700 that was in the bus when I purchased it. When the $$ permits, that one will get the whole kit n kadoodle.

[bajaman72]

Made arrangement to get my cylinders to the shop to get inspected/honed if possible. The broken exhaust stud will be repaired as well. I would like to save my rebuilt heads for the original engine which I plan to get to soon.

[Bleyseng]

Hopefully you sent the pistons along with the cylinders for inspection. They can measure them to see if they can be honed and the piston clearance will be still in spec. Too much clearance and the pistons will rock making the rings wear out faster.

[bajaman72]

Yup, Pistons too. Running them down to Rimco on Saturday.

[bajaman72]

Progress is still moving along. Although slow.
Pistons and cylinders have been checked and honed. He also balanced the pistons.
Heads checked good and missing (not broken) exhaust stud was replaced.

I decided to get to work on the crusty original fan. It took a couple of solid days of work but finished up tonight. Looks great! I can see the timing marks now!
After it's painted should I mark the timing marks with something or will I be able to see it okay?

I also got the short block into the parts washer and gave it a couple of go rounds. From what I can see everything looks
pretty good inside. Cam looks good. Lifters look good with crown.

Picture of clean engine.




And aftershot of the crusty original 1700 fan




I'm going to finish blasting the under cylinder tins and the box of blasted tins go to work with me on Monday for primer and paint.

Also I have to thermostat pulleys, one plastic and one metal. Is there a preference on which one to use? Both are in pretty good shape.

[bajaman72]

Forgot to mention. My brother in Gaviota found me a middle seat (I was missing) on Craigslist for $100! I've seen them for $300 and they look like they just got pulled out of a burning bus!

I have a bunch of type 1 engine parts in my bus at the moment, but it will find it's way inside soon.



It even matched my bus. Someday it will be re-covered to match the rest of the interior.

Nice score on that seat!

Achtung!
Here is the Itinerant Air-Cooled pulley painting template:

A white "vee" around the timing notch on the inner pulley half.
A white line in line with it on the outer pulley half for #1#3 valve adjustments, going around the edge of the pulley so you can see where it is at any point in rotation.
Two white lines 180* away from the timing notch on the outer pulley half for #2#4 valve adjustments, going around the pulley edge so you can see the two lines at any point in rotation.

Make the 180* determination by rotating the engine until the timing mark is lined up with the left protective screen bolt hole in the fan housing. Your #2#4 marks will "bracket" the right screen bolt hole.
Schnell!

Do you have a picture by any chance??

The Dellortos made their way to the parts washer recently.



After a couple of go arounds in there it will get dis-assembled and dipped in this stuff.



I have a couple of kits I purchased from CB Performance. It wasn't the basic kit, mabey the next best kit??
I don't remember and need to track them down... they are in the Bus.... somewhere..

. . . . questions?

[bajaman72]

Thanks Colin. The picture was like a thousand words.

I'm at a total stop right now. A few days ago my engine fell off the stand. My fan shroud was nice enough to break the fall. The case received a bent head stud and the flap bar got tweaked pretty good.

I'm pretty frustrated with myself at the moment. I need to step away for a couple of days and clean/re-organize the garage. My baja has been at the shop for a while and I'm missing it. I'll get over there next week to finish it up and bring home... then I'll have my "teaser" back.

[bajaman72]

I ended up pulling everything out of the bus only to find the rebuild kits were not in there
I found them behind my workbench. Anywho, I tore apart the crusty original 1700 to rob it of a head
stud that was bent when the engine fell, sounded like glass breaking when I was banging off the
head and cylinder.



Not pretty, but effective. Only one head appears to be trashed (water damage) and cylinders. The other side came apart easily with no apparent water damage.

Today I got started on one of the Dellorto's



here it is all finished up. The picture doesn't do it justice.

[bajaman72]

Finished up the other carb today. I'm pretty happy with the way they turned out. One of the kits was missing the gasket that goes under the linkage plate. I'll have to dig one up or make one.

[dtrumbo]

Umm... what are the hose barbs on the intake manifolds for?
