Hi,

I took my z to two shops to repair the exhaust manifold leak:
- One said that he needs to remove the head and everything on top of it to get to the exhaust manifold, and he will do a head gasket job while he is there.
- The other said that he doesn't need to remove the head to get to the manifold and no need to do a head gasket unless the car needs it.

Please let me know your opinions as to which shop should I go to and what is the difference between removing the head or not to get to the manifold.

Thanks

hahahah

the first one is straight out lieing and wants your money...

the second one looks like he knows what hes talking about!!!

all you need to do is take off the intake, and boom the ex manifold is right there. then pop that off, put new gasket in, and put everything back on! should take you a day if you dont know about cars...shoud take them 3 hours.

If you do the job yourself, this is an excellent opportunity to replace the intake & exhaust manifold mounting studs. Cheap insurance. Don't forget to use anti-seize compount on the studs and use your torque wrench.

The first guy has probably worked on an 82-83 before and knows what a BITCH it is to do with the head installed. The second guy thinks it's like an earlier car and is fixing to learn what the first guy already knows.

You -can- do it without removing the head but I'm not sure it's faster to do it that way. The later manifold is shaped where it a total PITA to get to the bolts. It's kinda a toss up which way to go time wise and getting a new head gasket isn't a bad thing. Don't be surprised if the second guy calls you back saying it isn't like he thought is was! Doing this gasket on a 75 280Z is easy, on an 82ZX it isn't.

Steve's right. I won't even consider changing out a intake/exhaust gasket on a later ZX without pulling the head. The head and both manifolds can be pulled in less than an hour. The manifolds can then be removed on a bench, reassembled and installed as a unit.

Steve and Stone are both right. I learned the hard way on a friend's 82zx, it was like death only worse. Besides, wouldn't it really suck to have guy #2 do the job and then blow the head gasket a week later?

I am not siding with either shops but just to let you know, the second shop has been in the business for about 20 years, he is not a z specialist but he he tries to save me money and save time for himself, he's asking $450.

I have to agree with all of you, the first shop is a z specialist, but he is darn expensive, he wants $700 for the job without manifold replacement, including the head gasket and $900 with maniflod replacement

I don't think I can do it myself, unless I find a home mechanic somewhere near by to help me out.

What do you think? Please help.

Thanks

So the first place that isn't a z specialist thinks he can change it without removing the head and wants $450, the other shop knows what's involved and knows they need to pull the head and wants $700? Have I got this right? If so, go with the people who KNOW what's going on. Depending on where you live and the local labor rates, $700 sounds about right. More than likely the manifold won't need to be replaced but those models are the worst ones about warping beyond belief!

Yes, you got this right. I made a mistake listing which one first and second, I just revised my post to correct. But you got it right.

Suggestions:

1. Don't attempt the job yourself. There are too many varibles.

2. When you have made your decision, as to which shop, write out an AGREEMENT.
--List what you both have agreed to.
--List each procedure separately and the agreed cost.

Be sure and don't present it like you don't believe or trust him.
Just ask hiim to sign to prevent any future problems.

Example: Twice I have left my car without an agreement and in both cases when I went to pick it up, the price had changed. One time it
was $400 more than the agreed amount.
One time it was $1000 more. And it was pay or no get the car!!



Good Luck,

Thank you. I'll make sure to get a written estimate before I drop the car at the shop.
