What do you say to a machinist to make 1.7 heads work on a 2.0?
I'm halfway through a top-end job on my new to me 78 Westfalia. Just about to swap on the rebuilt heads I got off the Samba and they don't fit. (IMG:style_emoticons/default/headbang.gif) Same exact casting number, but no go. I'm guessing when they were rebuilt, they had them set up for a 1.7, combustion chamber is different too.
I'm royally screwed, cause I needed this job done tonight.
Also, can anyone recommend a shop in the greater Denver area that could do this fast?
Thanks
Samson

The heads will not slide over the cylinder lip.
I only have access to hand tools and what not.

You will have to have a machinist open em up.

I have no clue how to help you as I am in Cali.....

Lets see who else pops up tonight and may be of some help.

You will need a mill and the appropriate cutters and head for this operation.

Yes, that's what I think the problem is. So what would I say to a machinist? How much should I tell him to take off?
Does anyone in Denver have a spare, working 1.8 head laying around and is going to be up for another hour, call me (440)935-2848 please (IMG:style_emoticons/default/pray.gif)

Take a cylinder with you and have him cut to fit...

OR

Measure the cylinder with the right tools (Good caliper) and tell him the specs.

If you ARE USING YOUR OLD CYLINDERS!!!! Take the old heads with you and use them for your measuring template.

AND

Don't worry. The machinist will dictate to you what he needs.

Are you using head gaskets on these cylinders?

Yes, I'm using my old cylinders, and no, I'm not planning on running Head gaskets. So I should just bring one of the heads I pulled off. This is something I can more or less have done anywhere right?

you need to lap the cylinders to the heads.
Each one to its individual head chamber...

YUP... If your old heads fit your existing cylinders.

Then the machinist can take the measurement off of those.

Kewlll. Now that part of the battle is over.

All you need now...... Is a machinist.

So who has a mill in their garage????????????????

Don't forget what R Towle said.

"You need to lap the cylinders to the heads.
Each one to its individual head chamber..."

This is a mandatory step.

You will also need to check deck cleareance from the top of the cylinder to the top of the piston. On a vanagon (which I know nothing about)
I B guessing your deck would be about 40 thou+.

Use the search function if you need more info on this.

You can use a comet cleanser and tooth paste thick slurry to do this at home.

I saw a thread from Len Hoffman that he sprays coppercote on the cylinder/head sealing area to promotes a FASTER CARBON SEAL BETWEEN THE HEAD AND CYLINDER. (new one on me)

And use the right torque wrench...!!!!!!!!!!!!!!! On clean threads!!!!!!!!!

Let us know how it goes........

All I can tell you is to call Painter's Grinding in the morning and ask them who does their machine work. You're not going to get this done tonight that's for sure.

Sleepy-time...

I guess I was hoping Alpha had a mill in his basement. I have Painter's Gringing on my to-call list along with 3 other places a little closer. 8 am their phones will be ringing. I hope I get some answers.

Yeah. I have a mill. Just no basement.

I'm terribly terribly sorry. But the mill has a couple of titanium hubs setup on it, and I can't lose the position.

Next time, I swear!

Actually....

I do have a lot of friends... There is a shop here that I used to work for. There is a guy. Rob. The place is called Argus Systems. Now you have to be a little sneaky. The address is 3821 N. Blake, next to the baseball field. If you call down there. Or drive by, if you don't get an answer. Offer Rob 100+ bucks and he will very likely do it for you.

You can get it done tonight, if you can get ahold of him.
