While putting my car back together, I have found that at lest 3 heat shields are missing. Can someone with a PET program help me out with part numbers and maybe pictures? Anyone have suggestions on sources for replacing these (new? used?)

The shields missing are:

1. motor mount, right side.

2. side of block below headers, right side (two allen head bolts and a short piece of fractured aluminum still present.)

3. starter motor.

Anyone?

 

I see what I can do when I get home.

 

Didn't see the one for the MM, the one on the header(right on top of the oil filter housing)#951-107-053-01.
The starter shows two, left 951-604-043-00
right 951-604-454-01
Hope this helps.

 

Excellent, that does help. I have the one bolted to the left motor mount; I imagine the right side is the same, only reversed.

Thanks for the help.

 

I don't know if nine-44 is talking about this one, but post 86ers should have heat shield above & protecting the oil level sensor that enters the oil pan on the pass side.
I'll get the number if you need it.

Thanks, Special Tool, that one is actually on the car. Anyone have a number for the right side motor mount heat shield?

 

951-341-108-02 is the # for the right side motor mount heat shield. Sorry I didn't get back sooner, been in the garage playin with my turbo engine too. Gettin close!

 

how incredibly important are all of these? from my experience they rattle a lot, are extra complication / weight, are they really that crucial?

In most of these areas, the primary heat transfer mechanism is radiant. The best way to reduce the heat transfer to a particular component with a line of sight to a very hot (exhaust) component is to block it with something to deflect (absorb) the radiation. As an alternate to all the sheilding, you could wrap everything with ceramic cloth to reduce the emmitted radiant energy.

 

Based on the shields that I still have, Porsche has done a good job on minimizing weight (nice cast aluminum pieces.) I have new OEM motor mounts; I would like the heat shield that will help make them last, as that is not a job I want to do again soon. A PO put a rebuilt starter in; I figure that heat shields may help it last longer. I have chased down some of the existing rattles (missing bolts, etc.), and am prepared to chase more down and cure them if necessary.

 

Actually, the heat-shields are steel. Aluminum absorbs and transmit heat too quickly. The only heat-shields I've had rattle is the one on the body of the car itself next to where the exhaust wraps under the car. One or two of the studs on the body had been pulled out by someone overtightening the nuts holding the heatshield on. So it was held on only by one nut and the ends were rubbing on the body...
