manifold heat shield

[RicanBeemer]

Hello, 

 

is this the correct manifold heat shield for a stock 1973 2002?

or if you got a good one cheaper let me know

 

Thanks

it'll fit your '73, but it wasn't the one that was used.  Modell 71 cars (257/8/9XXXX VINs) and all squarelights used a much-less-attractive (and long-lived) sheet steel heat shield that either rusts out, or the bolts snap off in the manifold when you try to remove it.  The e-bay one you mentioned is for the earlier roundies (166/7XXXX VINs).

Mike, the beautiful aluminum heat shields returned and made a final appearance on the 49-state ‘76 models, such as mine below. I don’t know if the ‘76 heat shields are interchangeable with the early shields, since the manifolds were not identical.

 

Best regards,

Best option could be to remove exhaust manifold and take it to a machine shop to drill them out unless you have access to a drill-press. And new and improved OEM hardware a little pricey and think it is worth it given issues with ordinary hardware.

Just buy a new e21 exhaust manifold gasket that has the spark plug heat shield

Ya good call with replacing with good quality hardware. That's one thing I definitely learned a lesson on from the past.

As for the bolts... I got them out. Just an annoyance and major time sink. Luckily I have the Bridgeport in the shop, I just drilled a pilot hole and carefully plunged an endmill.

Hello

 

Thanks all for your help, Am new to the BMW 2002 world so I have a lots to learn.

 

I already made  the mistake buying a Weber carburator that turn out to be a knock off, thats $200.00 down the drain.

 

I been spending tons of hours on the site learning on how to keep my car on the road.

 

Buckeye, am going to order those bolts to make sure they last, thanks.

 

I always like the 2002's, now I finally have one, very happy.

 

Thanks all.

  I tried to buy the bolts and the total was almost $22.00 with tax and shipping, I will take a chance with the stock ones, thanks.

Just use some 6mm X 6 or 8 mm long bolt with a larger washer for the heat shield       Use some never seize on them

[stephers]

and those bolts from ECS tuning are just copper clad    not the real full copper that the original were

Neither were they.  Copper is too soft and wouldn't work as a nut.  Test with a magnet.
