Exaust troubles....

[New_BE]

Hi there..well winter is here so i figure it's the perfect time to save up my money and get everything i need to fix things on th Z. At teh end of summer i noticed that where the exaust manifold connects to the head that it has a leak on the end nearest the windshield. So i called to see about a gasket that goes between there...they said they didnt have one. So does this mean that it's metal to metal? And what do i do to fix this problem? if i put my hand by there u can feel alot of air coming out near the engine. Doesn't sound good either. And exaust gets into the car when windows are down...thanks peoples again...Since i'm gonna assume that i need a new exaust since the old one is quite rusted and such would a turbo give noticable results....or would i have to change the other things such at the cam, have a better system for fuel delivery since i got dual rountop su's on it? Anyother ideas are welcome? thanks

Lincon,

I don't know who you called, but don't call them again!

Motorsports Auto 1-800-633-6331 Has your intake/exhaust gasket, part #10-2511, $17.40. Your car will be much more of a pleasure to drive without the exhaust leak!

You asked quite a few questions but I'll answer one for you. You should be able to get an exhaust gasket from some auto supply store. If not give Motorsports in CA a call I'm sure they can hook you up. Do not run metal to metal you will end up with more leaks than you bargained for. The exhaust manifold always looks rusted, this is normal. Unless you have cracks in it, keep it. If it is warped then you can take it to a machine shop to have it checked & fixed. Also always replace ALL the studs & bolts. DON'T reuse the old ones as they get brittle with age and end up breaking (You can order these from Motorsports also). Headers are up to you if you have an extra 300 bucks. Get a nice 2 1/2 exhaust with a freeflowing muffler!:classic:

Well thanks alot that helped alot...I called a local parts store...but they dont' really deal with datsuns and such type cars...I'm gonnna talk to the guy i bought the car from since he shuld know who serviced the car before i bought it. Any suggestions for a godo free flowing exaust Ed? And about them headers? would i notice an improvement in power? And what is the pupose in a header? I'm new to cars just tryin to learn here. thaknks again the info was very helpful

There are several free flow exhausts out there it's all what you prefer and off course $$. I'm using a flowmaster but that is just my preferance. Now the header, you probably won't notice any power gains just installing the headers by themselves. But ask anybody and they will tell you that if you plan on doing several modifications to your engine the place to start is with some headers and a free flowing exhaust. This allows the engine to breath better. After you have the exhaust done all the other mods will benefit from it. Just the exhaust will give you from 5-10 hp. not really noticable in street driving but it does make the car sound good. I do suggest that if you end up getting headers make sure you get the ones with the "Jet Hot" coating. They look good and keep your investment from rusting.
