hot air in engine comp

i was trying to adjust the timing and man there was a LOT of heat coming up thru all the holes i have in my tin.

i think i have the seal that goes around the turbo, but how can i plug all the other holes in the tin?
i guess there is a seal that is above the muffler.
any other ways to stop the heat? my bumper gets so hot i cant touch that eirther.

how about sealing the IC to the turbo tail? i have been looking for seals and ways to block the air from going around the IC, but no luck.

In your other recent thread I posted a link to an old thread of mine showing/describing how I made an intercooler shroud for my Garretson (not sure if you saw that).

Also, over the years, I have blocked every opening in the tin with either plastic and/or rubber plugs (often trimmed to fit) and aluminum tape that I then painted black. I also glued in insulation/heat shielding above the muffler, turbo etc (on the underside of the bumper and such). All of this seems to have helped keep hot air out of the engine bay, and also seems to have reduced the temp of the bumper and rear fenders/quarter panels.

I think this means you're driving too slow

In the above picture you are missing the following (orange seal that goes in the space between the compressor up pipe and tin - fills the gap) -

And also the following (rubber grommets for where the oil pipe passes through the tin in the above pic - Regarding the 1st link - it is not clear in the PET where these go, but I am fairly certain that the second link is the right size for the oil pipe pass-through space (you could measure that to be sure). Regardless, they are cheap . . .

This is the engine compartment seal you asked about - the rear section is part of the sides (the part closest to the firewall is a separate, 1-sided strip) . . .

http://www.pelicanparts.com/cgi-bin/smart/more_info.cgi?pn=930-504-170-01-M136&catalog_description=&Engine%2520Sheet%2520Metal%2520seal%252C%2520%2533 %252Dsided%252C%2520%2539%2531%2531%2520Carrera%25 20%2532%252F%2534%2520%2528%2531%2539%2538%2539%25 2D%2539%2538%2529%2520


I also just noticed in your picture that you have an aftermarket turbo drip tank so the original hole for the OEM tank breather pipe is open - on mine, I could not find a suitable plug for that (many years ago) so I just used a piece of aluminum tape to cover the hole and painted it black - has held up fine . . .

Great DIY work on your I/C shroud Ronnie.

My solution is going to be dremeling my OE shroud until it fits around my Garretson - at cursory glance this should work good enough / better than nothing.

thanks! do i have to drop the motor to replace that? i was thinking there was just one peice that went across the back.

i get frustrated with the parts side of this site sometimes. finding 930 stuff is REALLY hard. it took me 30minutes to find the 2 Orings on the IC AFTER i had already found them once and ordered them. they were under different catagories even thought they were for the IC.

i think what i am going to do about the empty holes is get my greenly hole punch and punch some round disks out, put one on each side and put a bolt thru them to clamp them together.
i was just hoping someone out there new of something better.

Thanks Paul!

T77911S -

I imagine you can replace the engine tin seals with the engine in place (I replaced mine when the engine was out, however).

Regarding finding parts - I gave up trying to search the Pelican site for parts long ago (for the very reason you mention) and instead, just look up the part numbers on the Porsche PET and then type the numbers into the Pelican search box.

i plugged the holes in the sheet metal on the sides of the motor and the one by the distributor. i used 2 fender washers with a bolt thru them. a 1.5inch washer barely covered that one buy the dist. had to get my wife to help. took at least half an hour to do that one. no room to work.
as you can see, the turbo is not centered in the hole. i dont know if that orange rubber seal is what goes there or not. i can smell it sometimes.
i have not done anything about the gap above the muffler. that will take some time to put in that seal. i was thinking of putting a piece of metal back there to at least reduce the heat for the time being, but what about the turbo hole?

can hot air in the engine bacy effect how it runs?

my wife was strattleing me while i was under the car. i threatened to take a pic of the nice view.
