Just spoke to local dealer service department, they said it is "possible" that a mistake in install could cause damage to one cylinder. The jusry seems to be still out here - some people say yes some say no.

Now, to pay for a second opinion is going to cost me over $500 to pay for dissassembly of th head etc.

Do I:

1. Call the garage that did the work and say "hey I think you damaged my car fix it for free" and hope they agree (and damage my relationship with them, risk them saying - prove it no way)

2. Go to another garage or dealer and pay for another opinion (I don't have another indie service place I know and trust) then if conclusion is yes first garge damaged my car, try to recoup loss of second opinion along with the reapirs

3. Suck it up and hope it is the $1500 valve and have first garage fix it, not investigate further

Installing a used engine is just not worth it - I can buy a 1995 lower miles car for $4500 which is about what it will cost for an installed used engine in mine.

What are my legal rights here regarding second opinions and proving that damage is their fault if that is what is concluded?

I am not jumping to any conclusions here I do understand it *could* be a coincidence, but I want to get what I am entitled to if they did screw it up.
