Asked by Feb 18, 2013 at 08:11 AM about the 2002 Saturn S-Series 4 Dr SL Sedan

Question type: Maintenance & Repair

My 2002 Saturn SL has 108000 miles.  I have owned it since it was new.  I have had to replace a front spring and tie rod (on the same side) within the past year. I am now told it has a small head gasket leak. The car has been serviced according to the book (probably more).  My choice is to add oil or replace gasket to the tune of $1200.  Since the car is only worth $1400. I would like to fix it but people are telling me that it is not worth it.  Please help

If you plan on selling it soon, then I wouldn't worry about fixing it. But it's worth it if you like the car and plan on keeping it for some time. Do get some other estimates to see if you can get it done for a little cheaper. I suspect you can get it done in the $600-$800 range.

Is your oil a chocolate/milky color on the dipstick and over full? IF so, it's not a small head gasket leak, it's big and "big" can mean an opening the size of a pencil lead and IF it is in fact a blown head gasket it will only get worse real fast ..does it over heat John?

Like David said, check for the chocolate milkshake on your dipstick and in the coolant bottle. A percentage of heads on these cars have a casting defect and develop a crack in the head, leaking coolant into the oil. But from your suggestive answer to "add oil" Im assuming that the problem is primarily oil burning, in which there is no cure for(save rebuilding the bottom end). Let us know which of the 2 problems youre having.

Thank you for your suggestions Alex. I have driven about 150 miles since the oil change. The oil is nice and clean (no milkshake). There are spots in the driveway and my parking space at work. Is it worth have the "bottom end" rebuilt or should I just add the oil. I never mentioned that I only drive this car about 6000 miles per year now. It would more cost effective to add the oil but way less green. I am thinking that by rebuilding the "bottom end" that the top end (if there is such a thing) may need rebuild sooner than later.

Just run the car if youre not driving it that much. These motors are notorious for burning oil if you dont change the oil religiously every 3000 miles. The problem is that the pistons in these motors do not have oil drain back holes to allow oil to fall back down into the bottom of the engine. There are only 2 little reliefs on each side of the piston to let oil fall back down. As a consequence, the dirty grimy oil will gum up and make the oil control rings get stuck, therefore allowing the oil on the cylinder walls to get burned up during combustion instead of getting scraped off by the rings.

In short, its not worth the trouble and cost of rebuilding the engine. That is the only "defect" of these motors. You could try the Marvel Mystery Oil piston soak to try and loosen up the gunk around the rings, but thats up to you. Most Saturns will burn a quart of oil every 500- 1000 miles. Even more if the rings are stuck pretty bad. Just keep checking your oil levels every couple hundred miles and add the necessary amount and it'll run forever.

Something to check on also is your PCV on your valve cover is that valve is stuck it will build up pressure causing the oil in the top of your engine to either find a weak spot in your valve cover causing a leak or going down your valve guides and burning in the cylinder causing your car to use more oil I have a 2000 Saturn SL1 with 165,000 and it uses about 1/2 quart every 3000 miles / per oil change. So it's worth checking out the PCV pull it off the rubber hose and shake it it should rattle or just replace it about 8.00 dollars or so. Thanks

Thank you. I had the oil changed today (B4, I got your Email) It had been 3000 miles and In my opinion only trace oil was lost. In High School I had a 68 Chevy Bel Air that went through a quart every 100 miles or so. I will check out the PCV valve tomorrow just for the why not of it. I appreciate that you took the time to answer.

I have a 96 Saturn SC1, it's main running hot, I check the coolant system and it's a milky thickness coming out of the coolant bottle. I'm burning a lot of oil. From my understanding it make be a blown head gasket, I can't afford a replace gasket at the shop for 1200.00, how can I fix this problem or go buy used head gasket for this car.

You can get it done cheaper. I'm needing the exact same thing for my Saturn. I purchased her. She had 71,000 miles on her. I love her because she is a manual drive. I racked an additional 62,000 miles since I purchased her. I had her flushed out but now I have no heat so I have to get the gasket replaced. Its gonna cost me $475. So call around and also ASK AROUND. people know GOOD MECHANICS that work from their garage (how I got my referral). The only draw back is that they perform the work ON THEIR TIME SCHEDULE. So she won't be ready for me until a week from now. Oh well. for $475 who's complaining???

YOUR FIRST PROBLEM WAS WHEN YOU BOUGHT A SATURN.. IT HAS 7 DIFFERENT CAR MANUFACTURERS PARTS IN IT. MECHANICS REFUSE TO WORK ON THEM IF THEY CAN. WHEN IT STARTED ,GM SAID IT WAS GOING TO BE A DIFFRENT CAR COMPANY, BOY ..THEY WERENT KIDDING.. I HAVE SOLD CARS FOR 52 YEARS, I OWNED ONE, AND IT WAS THE LAST ONE EVER !!! I WOULD'NT DO THAT TO ANY OF MY CUSTOMERS., HELL I WOULD;NT SELL ONE TO MY WORST ENEMY... GOOD LUCK...

That last answer is nonsense on several levels. A 2002 Saturn S Series does NOT have "7 DIFFERENT CAR MANUFACTURERS PARTS IN IT", quite the opposite. Where do people get such misinformation, and why do they spread it? During the time the S Series was made ('90 - '02), Saturn was a subsidiary of GM, not a division. In other words, unlike the divisions of GM, it was basically an independent company within a company. The S Series was completely proprietary and did not share anything with any division of GM, let alone "other manufacturers". In fact, that was one of the reasons the other divisions of GM complained so much about Saturn before 2003. Saturn had much more freedom than the divisions, which had to share and compromise with each other. However, S Series production ended with the 2002 models, Saturn had to start sharing, and every Saturn model other than the S Series was either just a half Saturn (the Ion and first gen Vue) or a Saturn in name only (a slightly disguised GM of Europe model with Saturn badges stuck on it) as Saturn became just another division of GM (2003 - 2009). The "real" Saturns (the S Series cars) have an excellent reputation for durability and quite a cult following, and there are still tons of them on the road 14 years after the last one was built. I've had four, and still have two that are doing great. As for your head gasket leak, it depends on where it is leaking. As has been pointed out, if coolant is getting into the oil or vice versa (milkshake) there's no getting around redoing the gasket or retiring the car altogether. If the coolant and oil are staying uncontaminated, many times a minor head gasket leak is no issue at all. For example, the Saturn dealer told me in 2006 (and 120,000 miles) that my 1995 SL2 has a "bad" head gasket even though it was showing no symptoms in performance or contaminated oil or coolant. I told them I'd keep an eye on it, which I have, and 10 years and 70,000 miles later it's still fine (at 190,000 miles). No symptoms at all, the coolant and oil are uncontaminated, and it still runs like a new car. So yeah, not all "bad" head gaskets are necessarily something that has to be addressed.
