Yo all,

If a mechanic is doing an overhaul on a 79's clutch, would it make doing work on the exhaust manifold any easier? Or not really? (wondering if I should get both done at the same time, but if it's not going to save money, then there's no point)

Cheers

well....

maybe slightly easier, once the tranny is out you can unhook the manifold a little easier i suppose.

Re: well....

Like Zphreek said a little, I was think about how much time I spent bending my arms around the intake/exhaust/heat shields trying to remove the bottom bolts for the first time. I could have saved probably an hour at least by being able to get under the car easily and see the bolts its also alot straighter of a shot for your arms, I can't hardly get my forearms in from the top leaning over the fender.

I'd just ask the person doing your clutch, cause thats what its gonna come down too, but I think you could save yourself an hour labor maybe.

Another thing is you may be able to actually torque the bolts back upon reassembley which is next to impossible when working from above - definetly saves that gasket and maybe some leaks.

Re: well....

well... at least the car may be on a lift where you can look up and use good socket extentions.

No,

Hi Ozzy79.
No. Working on your clutch , dropping the transmission to install clutch discs , pilot and throwout bearing, won't do a darn thing for your ehaust manifold . Now its true most any competant mechanic will remove the exhaust tailpipe sections to enable lowering of the tranny, however it's not still possible to ' see ' clearly what the condition of your exhaust manifold actually is. The trick to a bad exhaust manifold.....that is one with cracks in it or one that the intake/exhaust gasket has failed at.....is to to LISTEN carefully for hissing clues and for your Z beginning to sound like a HarleyDavidson motorcycle....then yes, please inspect the manifold. A mechanic will be able to use certain gas vapors to learn exhaust leaks as well as vacuum leaks. Any other possible way of discovery will only be to remove your exhaust manifold....and then your intake manifold.... or vice/versa.....because to remove the exhaust manifold will neccessitate a new gasket. And this gasket unfortunately covers both intake and exhaust manifolds. So a simple clutch job for say $200 - $350.oo suddenly can become a $650 to $850.oo with the manifold dismantling and reinstall labor. Save your money. If you suspect your stock exhaust manifold may have cracks than my guess would be at 150thousand miles it probably does. Get a aftermarket header. Victoria British and Motorsports offer excellent units. Well goodluck to you here. HappyTrails. shane-
