solid spacers, maybe 911 elephant foot adjusters, not stock springs from the color of them, rockers appear to have multiple shims.

Thanks - there were a ton of shins in there.

Pushrods has RTV on them - not awesome.

Once all of the cylinders head bolts are off the head should just pull off, correct? My guess is that it ain’t too uncommon for them to get stuck from heat cycling?

I wonder if those are water cooled Vanagan heads? They don't look welded, but more like opened up to allow air flow in.

Good morning gentlemen.

The heads have been trimmed in some areas, will better document once I get the head off.

Given that the cylinders are aluminum I am trying to avoid wedging anything between them and the head to lever it off.

Any ideas?

Thanks!

Is this the turbo engine? 5th head stud mod is what some guys did to try and keep the heads sealed.

Good morning Mark, it is.

Am I missing releasing a stud? Let me check again.

We are sooooo close to seeing what the heck this thing is!

The head has a 5th stud nut inline with the spark plug, about the place a regular head's plug would be. Makes for 10 studs per side instead of the regular 8. I think they are heavily modified and welded stock heads.

Thanks gentlemen, let me go look again. Have some penetrating oil on the area where the studs pass through the head.

Is there a chance the cylinders are re-usable?

Dont for get the under cylinder tin that is held by a 4-5mm bolt to the heads. But considering how wacky this build is not sure they are still there. (IMG:style_emoticons/default/confused24.gif)

Id say more like, frightening! (IMG:style_emoticons/default/stromberg.gif) IMO steer clear of these guys they are in a class of Motormiester & GEX! No, he closed his doors of the shop he had in Tahachapi some 20 years ago.
I was unaware he started up again, probably because the statute of limitations had elapsed for all the folks trying to sue him. LINK

I did not know that, let me make sure there’s nothing under there. I’ve been reluctant to get aggressive on removing it, will keep poking around and not force anything until you guys tell me it’s BFH time.

Thanks!

I wanted to follow up on several requests for pictures of the mystery engine after he tin has been removed.

Anyone recognize these bits?





The numbers on the cylinders are backwards. The right rear cylinder on a 914-4 engine is #3.

Do you have a picture of the bottom of the heads?

Stephens did my heads and supplied my pistons and cylinders back in the late 90s. He did what he did, I didn't know a lot better back then, but we straightened the cylinders and cut the bottoms. It worked out in the end, but apparently I got lucky.
