• Well i got good news and bad news. We will start with the good news.... i got the panasports    :gift: im guna rock them in the spring time with a sick set of summer tires. for now im goin to run the 14" snowflakes with gislavad snowtires (very aggressive tread pattern...great for Canadian winters eh) okay...now for the bad news,,,,i think im into a head gasket recplacement alreay  :banghead:  if i run the car easyand stay off the boost its fine but as soon as i get on the boost above 10psi i have compresion leaking into the coolant which causes the temperatures to rise real quick and over heats my motor blowing coolant everywhere  :banghead:  :confused:
  
  suggestions on what could be causing it??? i have arp headstuds in torqued to 75flbs should i maybe retorque to 100?
  
  please advise

• This is completely unrelated to your current questions but what gauge of wire are you using for your battery? It doesn't seem very think
• #49 by giulianot on 03 Dec, 2007 17:41
• currently its a number four gage wire and its turns over the motor quickly even on cold starts but i am going to do twin runs of number four gage wire eventually.

• Oh Right on. I really like the way this is shaping up and because of your post I decided to buy a DP from Dave. I just need to get a damn car on the road first

• Does anyone on here know of a better manufacturer of head gaskets for the aaz engine ? I talked to the people at arp and they did not recommend that i torque past 75flbs. They seem to think that the head is not perfectly straight and thats what is causing compression leakage into the coolant.  I don't see how the head could be warped as it just came from a machine shop that assured me it was straight.  I guess ill have to remove the head and check it with a straight edge myself :roll:

•  here are some pics of the head gasket failure
  
  
  
  
  
  
  
  
  
  
  
  
  i sent the head out for pressure test and check for warpage  i hope the head isn't cracked :mad:

• UPDATE
  
  SO i heard back from my engine rebuilder and he said that the head gasket failure happened because the steel pre cups were falling out of my aluminum head. This is not normal. The pre cup were nerled then pressed in then pinned. Anyways is under warranty, im getting a new head then i got to switch over my valves, springs, cam, injectors, glowplugs, over to the new head and have to match port and polished. It looks like i wont have my car back till after Christmas. :rolleyes:

• Finally I will be getting the head back on friday. Brand new oem aaz head with match port and polish on intake and exhaust. I'm gonna use a 2 hole victor reinz gasket this time and torque the arp head studs to 100 f/lbs. The cabby should be back on the road by Monday, hopefully :roll:

• good to hear it what parts of the gasser loom did you use to wire in your aaz? i'm doing a mk1 gasser conversion myself and starting to get a headache working out the wiring
  
  
  i just want to drive her

  I know how you feel!  as for the wiring loom I stripped everything to do with the gas engine management, computer , coil, and harness.  the power wire that went to the coil now goes to the i.p. solenoid. the tach wire that went to the coil now goes to the w of the alternator. I added a push button in the cabin and a relay under the hood for the glow plugs. Oil pres and temp gauges are the same!  :wink:  if you have any more questions don't hesitate to ask and good luck with your swap

  So I've changed my mind. I'm going to use a serpentine belt setup on the aaz , but my cabby has p/s as well. Will the p/s pulleys fit on top off the serpentine belt pulley without touching the frame of the car? Is the enough room to run serpentine setup and p/s in a mk1 cabrio?

  Thank you for this remarquable thread, interesting well illustrated. I have learned quite a bit and looking forward to read more about your rig.

  sorry i may seem like an idiot here but what do you mean by an i.p. solenoid? did you just connect the origional tach wire straight to the altenator without modifying the tach then?

  My uncle has been wanting to do this but he figures the TD engine is better off on the engine stand.
