Like the title says...

 

Who has O-ringed their block/heads?

 

How did you do it?

 

Did it work?

 

I am planning on doing this on a high-compression EA82T build (or two...) and would rather not "reinvent the wheel".

I don't think many people have here in the states, I'm toying with the idea but I have other options I'm considering.

I honestly think that as much as that is brought up here, than NO one has actually done it to their EA82.

 

I would suggest calling up some reputable machine shops in your area and talking to them. Keep in mind, you'll need a custom gasket too...

I believe that calebz has done so, based on my recollection of previous posts. (But that and $5 will get you a coffee )

 

Reputable... in my area... hmmm... I think the last one on this side of the water went TU (belly up) a couple of years ago... they charged more than NAPA/Schucks/etc. Last time I had NAPA resurface a flywheel, they made it a pretty dish-shape. Now I have trouble finding a place that resurfaces flywheels at all... most sell flywheels on an exchange basis.

 

Things like the gasket are what I want to hear about. Also, wire material (steel appears common for cast iron heads, but what should be used for aluminum?) and diameter, whether just one surface is done or both. Things like that.

 

My first exposure to O-ringing was last millenium (1970's, actually), and back then they were talking relatively large diameter copper wire/tube. Now I see mention of .75mm steel wire laid into a square-cut groove. One thought I was toying with was running a dry deck, but the EA82's cooling issues and access to the water-jacket/oil gallery would make that a problem.

The machine shop at Westbay in Port Orchard is decent, don't go to the Navy City shop, their machines are pretty worn out, had some stuff come back worse than it went in.

If the parts are available, go for it. Might be a way to get the EA82 to not blow a head gasket.

I'm toying with it for a 300-6 turbo project, I have had built Ford 300-6's blow the gasket between two cylinders. Of course, that was with 9.5:1+ compression, large carb, large cam, and dual exhausts. Cylinder pressures on one approached the lower end of the diesel range.

I've never heard of a diesel with 9.5:1 compression, that seems real weak to ignite diesel.

I mean the combustion pressures seen by the engine, large amount of air and fuel going in, big bang. On that engine, the ports (gasket matched) were the limiting factor.

I know this shop is not on your side of the pond, but ,try Autosport they are located on westlake ave. I get all of my parts from these guys, and if I ever get around to redoing my '02 (1975 bmw) these are the guys that will be doing my engine.

Also, I have an extra ea82 "almost" long block that I don't need. In case you don't have enough lying around your place.

I've never heard of a diesel with 9.5:1 compression, that seems real weak to ignite diesel.

I believe that he meant that the cylinder pressures of the ford 300 straight 6 were approaching what a diesel does. which with 9.5:1 I doubt, personally, but yeah.

the 300-6 are a very good motor for a work truck or the like, very torquey moreso than a 5.0 even.
