Oil in coolant.. and coolant in oil
Head gaskets seem to be the culprit. I do have the questionable cosmetic gaskets in there. Is there a how to on a gasket swap?
Any other advice, tips, tricks, etc would be appreciated. My first time tearing into an ls1.
So far I am planning on following the how to at http://www.ls1howto.com/index.php?article=2 and ignoring the cam swap. I am planning on going with GM MLS gaskets and a GM head gasket kit, and swapping out my plugs while I am in there. Should I also replace my springs? They have 60k on them now, here is the kit info:
http://www.lmperformance.com/4190/1.html
Comp LS1 26921 Spring Kit - Dual Springs with spring seats, titanium retainers, and steel jacketed valve seals. These are race quality springs designed to handle up to .650'' lift. Installs in factory heads without modification.
and my cam:
DUR @ .004" 282* / 286*
DUR @ .050" 220*/ 224*
LIFT .551/.551
OVERLAP 57*
LSA 114*
Thanks for any help!

Car is torn apart now, heads are in the shop. I tried using a plastic scraper on the old gasket, but it isnt coming off. I switched to carb cleaner and a razor.
Anyone got any advice on flushing the oil out of the coolant? A buddy of mine said to run Cascade dish detergent through it once its back together.

Straight vinegar should do the trick.

im not 100% on how you can "clean" the oil/coolant out of your system. someone probably knows a method that works. but now that the heads are off you prob should swap springs. 60k miles on the current ones?
and a GM MLS head gasket is great, i run those with out any issues

For the oil pan: just drain the oil pan, refill with cheap 5W-30 and put on a new filter, run it up to temp, then repeat the oil change with your normal oil flavor.
For the cooling system: most parts stores sell a flush kit that connects into your heater hose. I just pulled my big heater line off the water pump, added the kit's T-fitting, and was all set. You drain the rad, leaving the cap off and the drain petcock open. Connect a garden hose to the T-fitting, turn on your garden hose, then start the engine and run it to temp. All kinds of nastiness will dump out the rad.
edit: some liquid dishwashing detergent may not be a bad idea. Without some sort of surfactant to pull the oil off the surfaces, it's unlikely the flush will be fully effective.
When finished, remove the T-fitting and reconnect your heater hose to the water pump.
This is an option, but I use my ShopVac and pull the water from the engine by removing the top rad hose and applying the pickup nozzle to the hose end. It does a decent job of pulling the tap water out of the block cooling jackets...plus you'll want to funnel coolant down the top hose to refill the block when you're done.

Yes vinegar, you will have to run a surfactant.. thought that part would be common knowledge.
As for corroding your metal parts.. its a flush, not a coolant. Its only in there for an hour.
