Doing my gaskets here this weekend.

[slowchevy]

Few questions here..

1. What should I buy? Plastic or aluminum lower intake gaskets?

2. I'm planning on filling the radiator/cooling system with water to drive it to the shop where my buddy is going to do a fluid flush on the cooling system with green coolant. Is there any reason anyone would advise against this for a 20 minute drive?

3. What else do I need to know?

It's blowing coolant through the combustion chambers, thankfully no dex-cool milkshake.

I read somewhere on here about a royal purple product I believe it was that reduces coolant temps. Would it be beneficial to run that?

Just so I know I'm clear

Need: LIM gaskets, fuel injector o-rings (just 6), and what else. I'm about to go on RockAuto and do work.

Don't change oil and spin a bearing

 

[slowchevy]

wat

 

[1quick]

Aluminum gaskets, water is fine in the summer, change your oil a few times run it for 5 minutes change run it for 15 minutes change and your good, just change all the injector orings while your there, coolant elbows, the royal purple stuff isn't needed unless you doing race car stuff

 

[slowchevy]

I just put Royal Purple Synthetic in the car 5,000 miles ago. Should I run normal junk for the clean-out? I'm assuming I can just go back to the RP Synthetic after?

I have the dorman aluminum elbows sitting in my toolbox along with a new supercharger coupler and supercharger oil waiting for this too


So what all else should I buy for this job?

My list.. tell me what I need to add or take off.. I'm not entirely sure.

10 quarts of cheap oil
two oil filters
lower intake manifold gasket set (GM Aluminum)
supercharger to lower intake manifold gasket
thermostat
fuel injector o-ring set

Yeah I use whatever oil is the cheapest when I'm just flushing it

 

[slowchevy]

Would you say that list is pretty complete?

 

[slowchevy]

ZZPerformance - Lower Intake O-Rings #ZZ-LINTORG-38 do I need these? Looking at ZZP's shop to buy the stuff

 

[slowchevy]

Any benefit to using these GARLOCK gaskets for the supercharger to lower intake?

 

[slowchevy]

Also, the fuel injector O-rings.. it says each injector takes 2 o-rings, sets sold in 8.. so buy two sets of O-rings ?

 

[1quick]

I think the intake orings come with the blower gasket

 

[slowchevy]

All Garlock gaskets require coolant O-rings to be ordered separately.

 

[slowchevy]

Would there be any benefit to plugging the coolant ports in the intake on a supercharged car? I remember doing it on my L36 Impala and had lower IAT's and better gas mileage

You run royal purple? It's a 3800, you can re-use Taxi cab oil in it and it will be fine.

Not only is it ok to switch from Synthetic to non, I rotate through synthetic, Traditional, blend, and 5w-30 or 10w-30 with no bad side effects. It'll run on any of it no fucks given.


P.S. I'd also replace the valve cover gaskets and grommets while everything else is out of the way.

junk

buy RTV too

 

[slowchevy]

so use the paper or what. already have RTV

 

[smug]

yea stock gasket

 

[1quick]

I rtv the upper to the lower holds close to 20lbs of boost fine

 

[02BlueGT]

I use paper with thin RTV on both sides. The paper gives it something to tear when coming apart, so you do not have to pry on aluminum. Also, it seems to seal better.

FUCK GARLOCK!

 

[DanJ]

Fuck Garlocks, they blow goats. Even my garlock TB gasket shit the bed and it didn't even have coolant running through it. I blocked my LIM to SC coolant ports. If for nothing else it makes taking the blower and TB off that much simpler.

 

[slowchevy]

duly noted and swapped the order to a paper gasket. anything else?

So I've got the intake gasket set, lower intake o-rings, thermostat/thermostat gasket, fuel injector o-ring sets, vc gasket set and the paper blower gasket.

 

[G_T_O]

That seems like everything you would need!

 

[slowchevy]

:likes:

ordering noaw!

 

[slowchevy]

can't wait to give my big black girlfriend her first limjob

 

[SuperDaveGSE]

Remember to open up the coolant passage thats in the LIM under the TB. It allows coolant to flow to the rear head a little more.
