Mechanical head.

What would happen if i threw a 1.9 headgasket upgrade on a mechanical head? 

[bajacalal]

For one thing you would have a hole in the gasket that would stick out of the head because it's a straight surface at that part of a mechanical head.

yeah, i figured that, but what kind of complications would that cause, couldnt that be fabbed to work?
Has anyone done this upgrade to the mechanical head?

You would have a 1.9 headgasket on a mechanical head  

But yes there are extra holes in the 1.9 hg.  The smaller ones around the cylinders for cooling and the second oil passage. Wait that's if your putting it on a 1.6. Are there mechanical 1.9s I dunno lol

In any case I've read somewhere that the oil passage hole can be "patched"

i read a thread on vwvortex that mechanical engines are not compatible.

So im a little sceptical.

And to clear it up, yes a 1.6 engine.

He states that it's not suitable but he didn't say not possible.

As well things to consider, I've been told this several times by glegor is that your "mating surfaces should be almost perfect as the MLS hg may not seal as well as the fiber hg

I swear I read somewhere that this has been done.  Perhaps it was a different scenario

Ok, i will try. LOL see what happens. Thank you for your input Trips_B. IF anyone know of information that could be useful let me know. Thanks

[Trips_B]

Oh im sure you'll get some more input here once people log on

I did it on my build. I had 0 problems but I only posted 40,000 miles before the precup destroyed the engine. All mechanical block and head with the 1 notch aaz gasket. In my sig there below here is my build thread, but most of the pics are for some reason don't work anymore. Let me know if you need specifics and I will repost.

Why do you want to do this?
There is zero benefit to a stock or mildly modified engine and you end up with what could be a fussier head gasket, unless you also resurface the head and deck to the finer surface finish required for a MLS gasket.

i plan on boosting quite a bit. And i have heard that this is a very good upgrade if you plan on boosting more.

Ah, the information that was needed in the first thread for anyone to give an accurate answer How much boost??

Just buy an MLS gasket that's made for the 1.6TD mech head: http://gasketstogoblog.com/2010/02/06/mls-gasket-for-1985-vw-1-6-l-turbo/

^I see... why isnt this promoted more?
For the boost i was thinking 20-25psi daily. figuring thats a good amout, safe and gives a little more.
