Hi all,
my first post of 07, so happy new year to you all.
i have seached and read all the posts i can find relating to uprgading to a 1.9 metal head gasket. to a 1.6 lump.
i think i understand what needs to be done, but i wanted to double check what i'm reading. just drilling the block seems drastic, but if that's what it takes then so be it.
1/ the oil gallery below (see pic) cylinder 2 needs to be blocked off, there seems to be various means of doing this, from bungs, gasket paper to mastik.
2/ the block needs to be drilled with 8 extra holes to match the new gasket, as in the picture below?
3/ arp or raceware streeeeetch bolts recommended.
i have circled the holes in question.
is that all that is needed? or can you add anything.

I blocked the hole with 2mm rubber (http://www.kotinet.com/matti.farm/Audi/Moottori/122-2289_img.jpg). I did not drill those 8 holes, why should?
-
Hillshy old chap,
I don't have permission or can't see the image at that link... maybe no-one can?
Is this the mythical (OK, real) metal gasket trick, didn't know that, thought it was just a replacement gasket.
-
there needs to be a diy

Nope... can't see those pics, hillshy. I've wondered about doing the metal HG on my 1.6 solid lifter engine. Seems like a good upgrade that should allow more boost.
>>I blocked the hole with 2mm rubber.
So... you just cut a disk and put it in the hole in the gasket? What hardness / variety of rubber? I have a tough time getting my head around using a piece of rubber or even a slice of another HG to plug that hole. Doesn't seem like it would seal and if you get the size or thickness wrong, you'd be doing it again soon. Maybe I'm just wimping out.

Amen. I know Jake and others have done it, but I'd like to see the process.

Is this just for 1.6's or can the bolt sets and metal gasket be used on the 1.9TD (or is that a silly question)
-
The 1.9s come with the metal gasket so there is no need to upgrade, the bolts are an upgrade to either engine
Veeman, click on Audi80's post where it says "2mm rubber" and it will give you the picture you want.
What would happen if this hole wasn't plugged?
Ok, I just looked at pictures of the stock 1.6 HG I installed in my car. as seen here (http://img.photobucket.com/albums/v603/burnyourmoney/headgasket.jpg?t=1167874386)
and it looks like you (audi80) plugged a hole that comes on the original HGs
-
Thanks for that burn-y-m, so what is a non-metal gasket (a composite gasket)?
-
hi all,
thanks for all the replys to my post, sorry about the pictures not working right, i'll get that sorted in the few days.
veeman, im totally the same i like to check and double check stuff, i agree - it just don't seem right blocking up an oil gallery with a rubber bung, hence the quesions. :?
but those who have done this are all well clued up folk so i guess thats for enough for me. :wink:
-
audi80,
how do you do that with url imbedded thingy in "2mm rubber" in your post, nifty trick that :lol:
thanks for that picture, that answers my question, that's the 1 part i didnt understand, the oil gallery, i took prev posts to mean that it was being blocked off. which is why felt the need to ask. :oops:
metal gasket upgrade to solid lifters 1.6 engines,
1/ the 8 extra hole are not necessary but optional to assist in the cooling.air pocket and hot spots.
2/ make a bung as shown in the picture kindly provided by audi80.
3/ change the stretch bolts for arp or raceware types.
cool, i got that now.
once again thanks for all who posted.
cheers

is that a solid lifter HG??? audi80 has a solid lifter head. us guys with hydraulic lifters don't need to block anything am i correct???????????

Hi ,I'm new to the board....but now i'm worried :roll: I put a 1.9 headgasket in my 1.6 td...i did not block that oil hole off....what canhappen because of this not being done?
thanks :D

Metal gasket is bolt on to ´85 => engines which have hydraulic lifters. In older engines with mechenical lifters, you will have to block it. Otherwise coolant has a open hole outside.
So... you just cut a disk and put it in the hole in the gasket? What hardness / variety of rubber? I have a tough time getting my head around
I cut it from 2mm thick rubber gasket, I think it was from some gas cap gasket

Thank You!...it's on an 88 engine! :D

check to be sure first, its really easy to tell on a diesel. If there are 2 oil passages on the front of the block its hydro, if there is only one it is solid lifter.
-
i preferred my '86 solid lifter turbo diesel... it was louder, and it was more powerful. :(

evening all, did this picture show

Here are pics of a buddy's gasket job. He cut a piece of metal then used silicon to seal it. Once it began to set up he coated it with copper gasket sealer along with the gasket. You'll have to scroll down about 5 pics. There are some more pics of the build along with the gasket shots.

wow... he put the turbo in a pretty weird spot... isn't that getting a wee bit close to the brake master cylinder??? very interesting....

yeah i doubt it would hurt anything but it is a weird spot, it works nice there though, i've seen a guy with a crossflow mk3 he used the factory exhaust manifold and just flipped it and made and adaptor but it put it in about the same spot
-
Whats he using for the second filter for? Another oil filter, or is that his fuel filter?
-
That's the fuel filter. He just replaced it with a Mann.
Andrew, He ran out of Detroit Diesel Green for the cover. and it gives him an excuse to build it again with bigger valves.

where did he get that paint from? i love it!! i wanted to paint my block something green, but that works much better, is it high temp?

Hello there I am NEW to this forum and I want to say there is tons of good valuble info from some pretty knowledgeable folks.
I have a question and a tip for a 1.9 headgasket upgrade on a 1.6 td, firstly can anyone tell me after the gasket upgrade did your engine start okay in cold temps?
Here's a laugh for you here, I tried putting a TDI headgasket on a 1.6 and it worked but the preheat chamber area has differences which screws up the 1.6 in cold temp starts, the 1.9 gasket looks identical to the 1.6, YES aside from the extra 8-holes which arent an issue for 86 and up but I was just wondering if anyone can confirm any cold weather failures at all with the 1.9 gasket upgrade on the 1.6. I live in a cold climate and EVERYTHING must be in good order especially if you cant plug the bugger in
Thanx a bunch any feedback is greatly appreciated
