So im taking my intake off due to water being mixed in with the oil. I need to get whatever is on top of the valley out, my question is do I just pour clean oil and let it drain in the pain or do I suck it out with a vac?

Is this coolant mixed with oil or did you somehow pour water into the engine?

Here is a thread I made earlier where you replied.

I had the injectors out and it rained really hard so water got inside the intake

I'd clean the snot out of the oil valley just using paper towels. Buy five or more quarts of cheap oil and pour it all over the oil valley, let it drain and then use quality oil/filter and drive on.

Ok thanks will do. And what is the best sealant to use around the intake when putting on so it doesnt leak?

Permatex RTV Black, only on the front and rear china walls. Let it cure for 24 hours before driving.

So I got it apart and theres alot of residue that wont come off with just paper towels. Can I use a razor to scrape it off? I just dont want anything falling down in the motor. What is the best way to clean it?

Define "residue." Rust?

ak422

Not really residue but the old gasket is kind of hard to come off and its leaving off small marks.

Cover the lifter valley (not oil valley) with rags or paper towels. Get a razor blade and scrape off old gasket. Once done remove rags or paper towels carefully. Closely examine lifter valley and pick out remaining gasket material, then proceed with pouring in cheap oil...

OP

After you clean all the surfaces and get any debris out of the engine galley and pour/drain the oil part wipe all mating surfaces a few times with Acetone

Use Permatex Black "ultra" RTV on front & rear china walls, 3/8" bead, running up about 3/4" onto the heads/gasket

You need to drop the intake on "dead nuts" onto the engine so you don't push off the RTV.

One trick to making the intake placement easy is use a 3" long piece of wood dowel or a bolt the size of intake bolt but 2" longer with the head cut off. Use in front & rear bolt hole on one side of motor only as "guides" to drop the intake on. You can "rehearse" this before putting RTV on to confirm you have no wire looms or anything in the way first. Remove guide dowel/bolts and TQ to spec in the correct sequence (basically working center out criss cross) the intake bolts. Let motor sit overnight so RTV can cure before starting

Thanks guys and im trying to find the correct TQ specs but cant find it anywhere. Does anybody here know?

It's not necessary on this engine, it is known as a dry intake. No coolant passes through it.

shbox

Coolant does pass through the throttle body, though (if you have not done a TB bypass).

ZEN357

Now is the time to swap out the intake with an aluminum one if you have the money.

ak422

It has the bypass but now I have another problem. It just cranks and doesn't turn over. I smell alot of fuel coming from the intake and it was actually smoking a little. The car has been sitting 3 years and I believe I seafoamed the same week I parked it and let it sit that long. It was also losing power and running shitty, it had a fuel odor smell but I thought it was just leaky injectors which I just recently changed with a new fuel pump as well. Do you think the engine is hydrolocked? My next step is to take the plugs out and try to crank it to take all the fuel or water that's in the cylinders.

Reads like you are getting fuel. Next thing to check is ignition. You need to see if you are getting spark to the coil and wires. Most notorious issue with these engines is the optispark. Check easy things first, then you may need to pull the opti apart to see if the rotor screws backed out. Do you recall if there were any trouble codes?

ak422

I need to get my hands on an old scanner and see what codes show, also I replaced the opti about 4-5 years ago but only put about 1000 miles on it since. Might have to take it out and see. First i'll see if im getting spark to the wires /coil
