Mexico heads question

Discussion in 'Mech Tech' started by Dave Goddard, Jun 25, 2022.

  1. OK best left then, which is what I will do to preserve the "warranty" as well.

  2. The VW Engine Company also puts Nyloc where the temperature will soften it.. actually Nylon12 starts to get softer progressively from 23C to about 220C ish when it melts. By which point your heads are so soft they will crack ..
    A nut torqued up properly on a washer stretches the stud to lock the thread so the nyloc really is not needed. But then again, the CB nuts and fixing kit has Nylocs in it too.
    If it works leave it ..
  3. I reviewed the build videos the company provided last night. They show the engine through assembly and it's plain to see the heads are not new, with blackened exhaust ports and signs of inlet porting which I did on my heads to match to the inlet manifold on the last rebuild. They are also very stained and have a vw stamp on them as well as the mexico stamp. Seems unlikely that a vw stamp means new as i would not have thought any manufacturer would keep the vw in the casting for fear of trademark infringement. I wonder how this squares with a categoric "the heads are new" from the rebuild co?.

    Maybe your best angle is "Those heads my originals, I know it, you know it - pay my pump bill to cover the cost of one, refund me £200 to cover the other and we'll move on".

  5. Think you might be right there.
    Thanks zed
  6. Go ahead, just be aware they might go, ok send us your genuine VW heads back and we will find you some rando brand new heads to replace them.. at your cost.
    You probably sent them better than they could find as a new replacement at present. So they used the best parts they had to hand.
    If the old heads hadnt cracked already after use, they are probably less likely to crack soon.

    No doubt, so they should have said so and knocked off the price of the heads. Or sent the engine with a pair of new heads in a box.

  8. Quite right Zed. My issue is the apparent complete lack of honesty, failing to fess up when challenged and charging for things that were not supplied.
