I found a guy that can make copper head gaskets for the 1.6TD, they would be as good as or better than the 1.9 metal ones. There is a $40 set-up fee to get the pattern in the computer then they can be produced. Is there any vendors here that would be willing to stock these? Is there any interest in these? Here is his URL: http://www.headgasket.com (Gasket Works USA, LLC)
-
yes, I sent him my old 1.6 mechanical gasket and he said he could duplicate it. I am sure he could also add those water jacket holes that have been discussed previously
-
just for information, how much boost (turbopressure) can a copper headgasket hold?

-
copper is an excellent gasket material. It should be able to give a really good seal, better than the 1.9 metal HG.
-
i ever learned at school copper gaskets can re-used (by heating and make it cold by putting it in water), are those heagaskets also able to re-used?

I talked with them, the better part of 4years ago about the same thing, Because of the costs of setup and my time frame I decided to go the 1.9HG route. I'm glad I did, as even with head bolts a 1.9hg with eldelbrock gasket goup and a good flat head and block I have had no problems with a 490psi motor and pushing 40ish psi into it. (I had a boost controller go bad and I was hard into it) To this date the only thing that I have seen that causes these HG's to go bad are:
1. Overheating 50%
2. Inproper Install 25%
3. Non spec flat mating surface on the head or block 25%
With this being said, if you are planing on running 40psi regularly, or have a mech head, the copper gasket is probably the way to go.
Theoreticaly you can re-aneal a copper gasket, but imho, it's a crap shoot and just not worth it.
-
if someone like say passenger performance made them available, i'd blow my headgasket on purpose just to have an excuse to put one of these on haha.
-
setup is $40 and $104 to produce it, thats for a one-off. If one of the vendors (or a group buy) were to order a few, the setup cost could be shared and the production should be cheaper
-
What about the varying thicknesses? Would he just go with the thickest, or would there be options?[/url]
-
$144USD for a one off, or like $22CDN for a 1.9 :?
As far as verying thickness the vendor should offer the 1, 2 , or 3 hole thickness's. Though I have run a 3 hole on a 1 hole spec motor and didn't notice much of a differance (mostly just in starting it) The problem with verying the thickness too much is that you start to play with the squish area and that is just a whole nother barrell of monkeys.
-
how do you modify the 1.9 HG?
-
these engines have a funny squish. the angle is basically zero. on most engines the squish has an angle. that is, the squish gap gets bigger the closer you get to the centre of the piston.
i wonder if a custom set of pistons which have a proper squish geometry and a hemisperical dome cut into the middle of the piston top would be beneficial. i dont know if theres enough room to work with though, sence idi needs such high compression to start. maybe if proper squish pistons were made with the right thickness headgasket then the idi would not need such high compression.
-
Damn, I got played $160 for my last disposable fiber guaranteed to fail gasket....
-
I actually made a small run (4) of copper headgaskets about 3 months ago from a shop here locally, copper gaskets can be reused, and I could get them in different thicknesses as well. The thing is though, that a 1.9 HG with some goo and even just the stock stretch bolts hold lots of boost, like brett said, his hit 40 psi, and I think he had it set at 35 for daily driving, with the 1.9 gasket and headstuds, I woudl say the seal is good for 50psi+, but this is given that the block and head deck are STRAIGHT! That right there is the #1 reason for HG failure.
SO whos interested? :D
-
I have a hydraulic head Ecodiesel and I'm about to remove the head and replace the gasket. It's not blown, but I'm intalled a TD pump and plan to run up the boost and don't want to take any chances. I'll be using stretch bolts. Also, one more question. Where can I get a tool to remove the head bolts? It looks like a Torx, but not quite. Thank you.
-

You don't if it's going in a hyd motot. It's a direct fit.

how about a 1.9 HD onto a mechanical 1.6?

Its triple square, NOT TORX, same style your cv bolts are.

Actually, my inner cv bolts are 6 mm socket head cap screws. Where would I get a triple square tool bit for a 3/8 or 1/2 drive ratchet? Thank you.

I have seen those, they are aftermarket not factory hardware, Any good tool store should have triple square tools.

:D Here's a funny thing: :D
A Torx [is it 12mmIIRC?] DOES fit and torque the head bolts.
Even though they ARE a tri-square. I know this because I've done it. A crud filled head with gooed up bolts looked like 6pt to me on my first 'new' head post allen key back in the '80's. Only after removal and inspection did I discover 12 pt needed. Didn't buy a 12 pt for years (never saw one!).
[I do have one now though :oops: ]
the the axle bolts tri square 6mm is it? is different and the torx does not fit. Which is strange as it ought to be a scaled down version ( to do with torx teeth not being scaled down linearly) However a damaged axle bolt can be removed by hammering in a torx which will deepen/widen its 6 grooves.....Twilight Zone over... :shock:
-
Yeah, my aftermarket CV bolts were allens. They are now covered with a thick coating of RUST. :evil: Next time I'm getting the real VW bolts!
I tried to use a Torx to remove my head bolts. Bad idea, I stripped two and had to DRILL them out. Yuck! I went through like three drill bits. I had a hard time finding a 12mm 12-point bit, finally found some online when I started searching for "triplesquare", I think I finally got mine from from Snap-on or someplace like that.
The 8mm, I think I actually got at a local tool shop. It's not a chain store so that probably doesn't help you, sorry.
-
me too, I just want a metal gasket for my mechanical motor
-
So a 1.9 gasket is metal and the 1.6 is fiber , correct? I like the idea of using a metal gasket, and copper would be ideal. I use copper gaskets on my motorcycle heads and they work great. My 92 hydraulic-head eco uses a 3-hole fiber gasket. Obviously, fiber will squish more than a steel or copper when the head is torqued down. Does anyone have the gasket/piston-protusion specs for a 1.9 metal gasket?
-
I'd potentially be interested in one for my 1.6 mechanical head. I thought about using a 1.9 metal gasket as people have done, but I'm a little hesitant to cut plugs and try to match thicknesses / crush heights between materials.
Any chance you can price the per unit price factored out over runs of 5, 10, 15, 20 gaskets?
That'd probably make the decision easier for people if they can compare the costs and we can see how many people we need on board.
