View Full Version : What is this!?

Ok, so I have been meaning to ask this for a while guys/girls. It's in relation to the LIM gasket issue. I have not had this problem...yet (that I know of).

Anyways let me cut to the chase. A couple months ago (give or take a few weeks) my Low Coolant light came on and went off. I figured it was just getting low. Normal so far? I think so. So I get some coolant from inside the house. The DEX stuff that the cap says to use. I didn't mix it because I didn't put much in...maybe a cup (if we were measuring I'd say). When I took the cap off, I noticed the liquid was a brownish color...nasty...in the resivoir that is. The cap had some foamy stuff on it and smelled pretty bad.

I didn't let it bother me...I just said "eh, maybe I need a flush." So, a couple weeks ago (about a couple months after I put coolant in) the light came back and went off (usually when going uphill). The car never operated outside of its normal operating temp (needle half way on the temp gauge). I didn't let it bother me. Couple weeks later (yesterday) I got coolant so the light would turn off. My bro saw the foamy stuff on the cap and said that he thinks some stop leak type stuff was added to stop leaks within the engine.

Annnyways. He took a quick look and on the front cylinder head...on the side of the serpentene (sp) belt (left side of the car if you are looking at the car direct on from the front) the block was wet. It looked like it was leaking from the head (not bad...and the car was running for a good 30mins before this).

Getting to my question now. Is this something in relation to the LIM gasket issue? Do you guys think I need to replace it?

Car runs great, no abnormal smoke or anything weird. Just curious if this should be fixed before something major breaks and I get totally screwed.

TIA

Yep it's probably your LIM gasket. Sounds like the same thing I went through. I found a leak from drivers side though.

Damn. Is the foam stuff caused from the leak and stuff? Or did someone put some type of crap in there to stop the leak?

Either way ya gotta get it fixed and from the sound of it quickly. Sounds like its leaking internaly. Mine was external but thats not good either.

Hmmm. If it was leaking internally wouldn't it mix with something? Like the oil? Or go out the exhaust and would be noticeable?

The oil is fine. We checked that. No signs of any other chemical in there. I had it changed about 1K miles ago.

I figured it was in your oil. It will be soon if you do have a leak. I now man its a bummer. I went through it to.

I never saw any trace of coolant in my oil. But there was definatly oil getting into my coolant causing it to turn this ugly brownish color. Check the bottom of your oil cap for condensation.

Ok, I will do that once I get out of the office here and before I drive off.

Yeah the coolent is brown. Sometimes the temp will go over 200 (thats the halfway mark right?) on the temp gauge. Nothing alarming yet. About how much will it cost to get fixed? Or I should say, how much is the part(s) and how long would it take a garage to change it? Most places around here charge $50-65 an hr. I hope the gasket isn't that expensive, and I hope it doesn't take longer than an hr :(

To have a shop fix it your looking at least $700. That seems to be the lower of the average cost, at the dealer it could be as high as $1000. You can do it your self for less than 100 bucks, but lot's of time.

Just check the bottom of your oil cap daily, if it get's foamy than stop driving the car.

Oil cap is fine. That's an insane price to change a gasket!!! Essentially all you do is take off the UIM and LIM without breaking anything and just swap out the gasket, put the LIM on, hand tighten the nuts, then torque to spec....put the UIM back on and do the same.

Is there a HOW TO on this?

Damn I hate my car now. POS lol.

It's not hard to change the gasket, just lot's of labor. You have to remove the power steering pump, alternator, EGR crap, lot's of hoses, just lot's of time.
Yes there is a how to floating around here some where, it's what I used to change mine.

Kool. I don't mind doing the work. I will pick up a torque wrench next week and find that FAQ and stuff.
