The car is older that 1996 there for you dont need emissions testing. if you wish to pass, check the carbon canister and the egr valve. if the temp gauge says the cars not over heating and the engine doesnt appear to be hot, dont worry about it.

Removing gearbox

Here's your book info is below...
Most auto parts stores carry Haynes Manuals. You can order them from Haynes if needed. Or...often they are carried in your local library.

I have done Ford and Toyota clutches using these books. Clutch replacement is not hard, just time consuming...And easier if you have a lift.

Note: If like many vehicles, don't forget to replace the engine rear main seal while you have access with the fly wheel off.

You can call Haynes and ask specifically if the book covers the repair you are attempting. I have called them to get more specific wiring diagrams not always provided with the books. Very helpful in providing tech data... I have a Haynes manual for all my vehicles...makes maintenance and repair much easier than researching every I need to do something to my vehicles.

Best of luck finding the information you need...

Plugs getting wet with oil

Don't know what type motor you've got, but this same thing happened with a DOHC Saturn engine. In the inside of the valve cover there's an O ring in each spark plug hole, they need to be replaced. If this is the problem, you'll want to replace the valve cover gasket as well. Since you'll already have the valve cover off. Also when replacing the valve cover, be sure to tighten the valve cover bolts in the proper sequence and proper torque.

Can i put a bigger engine in my 1997 Saturn SC1 and go from SOHC to DOHC

Anything is possible. Do you really want to open that can of worms??? You will need to also change all of the wiring harnesses, all the emission controlls and the engine control computer to go with it. If you have OBD emissions testing in your area, it will be very difficult to pass inspection unless you transfer EVERYTHING. If you just want more power, it would be a whole lot easier to just buy another car with a bigger engine.

How to fix a headgasket

requires pulling the head off and replacing the gasket. not an owner serviceable repair unless you have a lot of tools. while you are at it you will want to do the timing chain as well. might make more sense to buy a lower mileage compatible engine out of a junkyard. most saturn engines from 96-98 will fit in there, you must make sure that if yours is a SL2, meaning DOHC your donor vehicle must have the DOHC as well as the transmissions are different on the SOHC cars. SC1 and SL1 and SW1 have the same engines and SW2, SL2 and SC2 are the same. something i learned a long time ago was that if you have a valve job done on the head before you put it back together, the piston rings will go bad within a few weeks. good luck

Cant tell if ignition module is bad, how do you tell if engine is DOHC or SOHC

Should be the DOHC. It will say Saturn 16v on the valve cover. Auto Zone can test the control module.

Is it very complicated to remove the valve cover to replace the grommets & the silicone & if not what is the recommended steps to take. thanks for any help my car is a 1994 Saturn SC1 SOHC

I replaced a valve cover gasket last night. The simple way of completing this taks is to un bolt the valve cover using the star tool. If I remember their is a total of ten bolts around the v-cover and in the center. Remove all bolts and clean them with carb or brake cleaner to disolve all the grease and dirt. Be careful to keep all washers that are below bolt head clean them to. You then would want to disconnect any lines or hoses connected (be mindful of where to re-connect them). Then very gently grab both sides of cover and pull toward front of engine until seal releases. Take cover out remove and replace all rubber grommets. Take a flat head screw driver and run along the seal making sure that the screw driver is under the seal run along crevice all the way around and in the center of valce cover ( where the circles are). You want the seal to be clear of all debris( and old seal). Use a clean towel to clean all areas where the seal once was with brake or carb spray. Clean the top of engine where seal rested and the circle area's make sure to use the silicone and cut the tip to desired beading ( you want the bead to be thick enough to fill the crevices where your old seal was maybe even more) After all area's have been filled wait 5 minutes for silicone to skin( a process where silicone is just begining to become tacky). Replace valve cover and make sure everything lines up install all bolts with washers into place and tighten reconnect all lines/ hoses and wait up to and hour and a half to drive. Although its safe to drive after this time it will take 24 hours to fully cure. Please forgive me for my grammer but I hope this information helps you.

I have a 1996 sc1 that needs a new starter. Do I need to pull the engine to replace it or can it be done without pulling the engine?

it will come off without pulling the engine but not without some effort you may have to take the engine mount lose on one side and raise it up about 2-3 inches

the timing belt on a 1.9l saturn is located under the valve cover on the left (passenger) side of the engine. this is the same on a DOHC or SOHC saturn motor. it is driven by the crank shaft and turns the cam shaft(s) in order to move the valves in the correct order. you should expect to pay at least 40 dollars for the belt itself. as far as installation... check you local service center.

Open the hood if it says efiohc or single cam on the valve cover then it is a sc1 if it says dohc or twin cam than it is an sc2
