I put the RTV silicone on it right after i took the picture...

I wiped out all the antifreeze that were in the oil passageways and I am getting my oil changed today.

Here'* the after story... and a few pictures...

I thought I saw some antifreeze leaking out of the throttle body area, but i took some pictures and maybe it was left over from the whole operation.

Got my oil changed and it all looks good... but an interesting comment on the receipt.

My L36 after shot.


Under throttle body front


RTV Silicone on back or LIM Gasket driver side


Passenger side LIM Gasket Dry -- that wet is from before... (it never really dried up)


Good Antifreeze level


CLEAN oil


Ha. ha.

You reused that elbow? Being the original, you should have replaced it.

It was in good shape...

when it cracks and leaks... then you can kick yourself.

but for now, good job

Thanks for your photos. We're about to do this on a '98 Monte Carlo.

I also found the info in the Techinfo section on 95-03 Upper Intake Failure Information.

This site is great

Pictures were the least I could do, if you have any questions feel free to PM me.

Did you replace the egr pipe with the smaller diameter pipe?

I just got my intake manifold kit from ZZP and it did not include one. I went back and read the description and does not say it is included. I then searched for on on their site and came up empty.

if by egr pipe you mean that stove pipe looking thing... no i just put it back together the way it came off... so i guess it'* still whatever size the regular one is.

Is there a particular reason for swapping it out for the other sized one?

The description of the APN kit suggest that the smaller diameter of the stove pipe allows for a larger air gap, between it and the plenum, which creates an insulation from heat transfer to the new plenum.

Guess I had done some much research, I got my kits confused.
So it'* not a necessary replacement but a possible enhancement to for their kit?

The Techinfo article here also indicates the Dorman kit includes the resized stove pipe.

But appears to be an incorrect description as it is not indicated, as included, on this site that does sell the Dorman

I just spoke with ZZP and they said what they sold me is the Dorman and does not include the stovepipe

So I guess I'm good to go
