• While I TOTALLY agree with wanting to try and repair the old head in terms of learning skills and what not, I just can't imagine spending $300 on a head that at best (and I'm being conservative) 50/50 chance of actually being usable at the end of the project. 
  
  If you're willing to run something that's been welded seven ways to Sunday then I really don't see how a Prothe head could be any worse - and a bare Prothe head is under $300.

• Something about "getting there is half the fun" that I find wildly appealing.  Although, I agree with you, I am usually frugal, but lets face facts, I am a Marine, and as such, a little on the insane side.
  
  thanks guys,

  getting there IS half the fun, but not when your project keeps pissing in your cheerios and giving you the finger every time you look at it or try to work on it.
  
  thats why i started doing my work right the first time. i wouldnt waste my time trying to fix a junk head. buy a prothe special. pretty sure smokey eddy has one. it runs, thats for sure. those cracks that got welded are going to open back up. and at the worst possible time.

• I'm not going to use it in my turbo setup you must really believe I'm daft?  I am going to see just how rough cold starts are on the 1.5 bottom end and use it on that with standard 1.5 N/A pump and injectors basically, I'm curious to know if an aaz head will really work, or be practical on a 1.5 bottom end.  I'm going in not expecting it to work and if it does..... well, then I have a good breathon N/A 1.5 with super low static compression, and probably ***ty milage, depending on how it's tuned.  Any advice?  Curiosity killed the cat...... and my wallet
  
  thanks,

• daft?
  im a stoner with a limited vocabulary, un common words dont get along with me.
  
  and good luck on the 1.5/9 n/a its probably gonna have around 15:1 compression or so, cause the 1.9 pre cup is almost 20 cc's, and the 1.5 pre cup is around 11 cc's. thats almost a 200% increase. might work, probably wont. it would be cool if it did tho. i just think i could spend 300 dollars more wisely then trying to fix a junk head is all. 1.9 heads are not rare. theres just not much VW diesel stuff in cali, or oregon, or washington really, but if we made a trip to canada one of these days, we would be set...

• you up for the trip kev?  You are a self proclaimed stoner after all   I'd go at the drop of a hat, but there's the whole Military thing   I don't have many choices on heads here, true!  I have a better one on it's way, and I am curious to try this, that's the bottom line.
• #292 by maxfax on 25 Jan, 2010 21:33
• IF it's just an experiment, why not just pressure test the cracked head..   IF it holds throw it on there and see what happens....   
  
  That's what I love about the crack engine..   I burn all sorts of crazy things as fuel, not to mention the other things I've done to it...  IF it blows up, oh well, I haven;t destroyed any good parts.. more or less...
• #293 by NintendoKD on 25 Jan, 2010 22:11
• But it wouldn't look near as pretty   Ok, now for some pictures.

• I have some pics of those fuel coolers I talked about, as well as some of the clean components I have back from doing all of the media blasting, the block is coming soon, and will be painted next, as well as the g60 intake mani.  I am having a hell of a time cutting up that audi 5000 turbo mani.  would fuel cooling be beneficial?  I am going to install a toggled pick up pump, and since it is fuel cooled, I wonder "SoCal is mostly warm all year" if it would be beneficial to cool the fuel? These were originally used for JP8 cooling, and they still have some inside
  1.5 N/A exhaust mani and dual D/P looks tons better cleaned and will be awesome when I grind the etra material from them and put a nice ceramic high temp paint on it.  I plan to put these on the 1.5 with the aaz head if it all works out.
  
  audi and g60 mani pre paint
  
  oil pan pre modification for the dry sump, I have some lines drawn on it now and am getting ready to cut it up to prep for changing the inside dimensions.
  
  aaz valve cover pre paint
  
  I know, white is tacky, but I think it will look good so screw off
  
  another shot, before I put the sticker back on
  
  Now for the fuel cooler
  
  plenty of options for connections
  
  current pressure connections
  
  I have two
  
  size comparison

• I got the new head today, It has cracks in the precups, so now I can add precups o the list of things I need as well as two cam keys, one cam/bolt and another aaz valve cover.  I will also need, all of the necessary parts for a full aaz head rebuild valves, seals, guides, precups, valve seats "my machinist broke one"  pictures to come very soon

• I wouldn't say white is tacky at all, but in a diesel, it might not be white for long
  
  You my friend have a touch of insanity that has made this thread a lot of fun to read.
  I can't wait to see where you go with this.
  
  now that mine is finally running I have to live vicariously through you guys.
  
  Cheers,

  I certainly try, don't I?
  
  I plan...... to go......... TO THE MOON, no, seriously now.
  I feel the need............ the need....... for speed  I do understand that it will not be a 1000 H/P engine or anything but Brake H/P wise it will be in a league all it's own.  I mean, what, the Mk1's weigh about like 1100lbs soaking wet with a full tank and a fat chick in the back?
