oil in antifreeze

I have a 98 gtp supercharge and I noticed today when I went to check my coolent there was sluge in my colent tank I checked m oil dipstick. And the oil wasn't milky I changed the oil about 3 weeks ago and it wasn't milky then... I'm ve been told by a few people that its either my headgasket or my intake manafold gasket.. I looked online and found out that gm used plastic intake gaskets and are known to go on the supercharger... I usual do all the work on my car I can but this seems like a job thafs a little difficult so I was wondering if it wpuld be worth paying to get fixed if not are there any cheap motors out there that have more power then the 3800 and would bcompatable with the stock drivetrain n all the other componets on the engine

Are you losing coolant?

Is the coolant in your colling system a orange color (dexcool)?

If so read up on dexcool and get back to us.

If the car is not losing coolant and or acting funny, its not a headgasket or intake gaskets.

I didnt look at it much today the tank, where you check it was dry only sludge in it. My cousin said he thinks there's antifreeze in my oil from when he pulled the dipstick out, I think I have some coolant in my garage so ill see how much will go in tomorrow... I also have engine knockin like when there's boost gauge is going up ( unfortenetly I have a stock gauge so I dont have exact psi) it doesnt happen all the time when it does the cars real quick.. the check engine light will come on sometimes and go off eventually when it was on a computer it came back as misfiring in cylinder six not sure if this is related problems but seen that the intake gasket can cause knocking thanks for the help tho may have to look into it some more.

I tried to clean up your post because I couldnt read any of it.

Since when do bad intake gaskets cause a knock?

If the check engine light comes on and it happens when you are getting into boost, you have a completely different problem.

Thats a ignition/fuel related problem, Like you need to change your plugs and wires kinda thing, if you continue to beat on it when its like that you are going to have a major issue on your hands.

Also, the overflow tank where you check the coolant is not the best place to determine if you REALLY have a coolant/sludge problem, because all the crap you are seeing has been there forever and dried up and thats what makes you think something in wrong.

Pull the rad cap and see how much junk is on it, if there is alot, then flush the coolant, THEN see if you are really having a problem.

And I dont think your "cousin" know what he is talking about.

You can't use the overflow on our cars as a gauge of what is happening with the engine. Please open the radiator when the car is cold and check there. Sludge is fairly common on older versions of Dex if air was introduced and in the overflow..well..it's open to the air. Very few overflows aren't nasty.

If there is something in your coolant besides oil, it is most likely transmission fluid, since the tranny cooler is inside the radiator. Over time the transmission cooler lines in the radiator can crack, casuing trans fluid to get in the coolant and vice versa.

Thanks for the help guys ill be flushing the radiator tomorrow ...I'm assuming I'm gonna have to put drexcool in it as aposed to the green coolent right.. and to do with the kncking I read on gear about it a little while ago and. Came to the conclutiion thatits eithet spark plugs wires or the cylender 6 injector was planing on doing the spark plugs this week n hoping it fixes I was lookin at the performance ones at auto zone for 8.99 would these be worth it or could I just get regular spark plugs.I've only had my gtp for about a year and its my first supercharged car so I'm kinda new to this

Stock replacement AC delco plugs. And what ever wires you want.

Green coolant is fine, just flush out all the old crap first.

Thanks you dnt hapen to have any little tips on gettin those back 3 pulgs outthey seem like there gonna be a ***** to get to read people just takin off the suports n rockin the engine forward but dsnt seem like sumthing I wanna do lol thinkin ima try n rig up sum mireors so I can at least see them

if you take the dog bones off, the one on the left side has a hole that you pull the engine forward, and then slide the bolt back through the hole in the bracket thats closer to the bumper, it will give you another 2 inches of room.

if you take the dog bones off and use a ratchet strap, you can get 3 or 4 inches of room, and clearly see where the plugs are, and have the room to get your hand back there.

i wear 3x gloves, i need to move the engine or the plugs would never get out.

I like to rock it forward and use the bolt on the passenger side. That's why there's an extra hole in the mount.

Personally though..even with the engine in it's normal place, if you look down..you'll see them. Best advice we can give you is remove the engine cover bracket. It's two 13mm nuts. They are a pain to get to (ratcheting flex head wrench, just saying) but it opens things up.
