3.0 With 2 Broken Studs....What's It Worth?

3.2 crank is not the same as a 3.0 crank. 3.2 rod bolts tend to do the murder suicide thing on 3.2 cranks. Good 3.0 cranks are common by comparison.

set of heads, $600 +/-
case $1200 +/-
crank $1200 +/-
etc, etc, etc.
it's worth the sum of it's parts.

Virtually every Porsche, the sum of the parts exceeds the value of the whole.. The smaller you part it the more you receive.

First and foremost, I am sorry to hear of this problem with your engine, especially the 3.0L engine. They are very good engines.

What is a surprise to me, and I AM NO EXPERT, is that your mechanic did not notice the two (2) broken head studs prior to the engine being resealed?? Why is this? If the case was split to reseal the engine, it would have been very obvious to an experienced Porsche engine builder that there were head studs needing attention. You cannot miss something like this fact. However, now that I have said this, it also depends on how much of the engine was resealed in the first place.

In this case, there is a big difference between the words, rebuild and resealed.

Steve, Grady and Henry is there a difference in reseal? Is there a top-end reseal versus an entire engine reseal? Shouldn't the work be labeled as such so as not to confuse or distort the actual work and cost of the procedure? Or, is a reseal just pertinent seals on the top-end of the engine without splitting the case and doing say the oil pump, crankshaft seal and flywheel seal which would require splitting the case (oil pump)?

Speaking only for myself, I consider a reseal job as addressing all the visible oil leaks.

Now, some areas require more disassembly than others (3.6 case through-bolt O-rings) so a lot depends on how much money a person is willing to spend to address everything. Normally, we replace all the gaskets, seals, and O-rings that are accessible during the normal course of the job such as a top end rebuild. Crank & flywheel seals can be changed without splitting the case, however any leaks at the #8 crank seal require full disassembly.
