Question about Saturn SL1

1 Answer

I'm replacing the head gasket on my friends 96 Saturn SL1 SOHC. I've heard 2 different stories about lining up the crankshaft with the camshaft in order to keep the valves from contacting the pistons. my mechanic friend says have 1 & 4 pistons TDC and the 1 & 4 valves closed and in that case the keyway for the crankshaft sproket is TDC. The Autozone online manual says to have the keyway at 90 past TDC which means the pistons are halfway in travel, but theres an error with that because Autozone says with the keyway at 90 past TDC that the timing mark on the pulley will be at 3 o clock but I tried it and its at 12 o clock. Who should I believe? Its very very expensive if I get it wrong.

Bring the crank to TDC while WATCHING CAREFULLY the camshaft, making SURE that the pistons are moving in the correct sequence as the valve train. Once you have the #1 piston on TDC, Set up your valve train with what looks to be the most logical position. Then and only then should you consider the factory spec for setting the lead/lag time of the valve train, in degrees. Hope this helps....accordianman

Dark water coming out tail pipe when I start my 1993 Saturn sl1


Oil in a cylinder is never good. There are several ways for the oil to get there and different prices to fix it.

Valve stem seals go directly around the valve and keep oil from the valve train from entering the combustion chamber. A worn or cracked seal can let oil run into the wrong place. Depending on how the camshaft and valve lifters are fitted, the valve stem is at the bottom of the camshaft and lifter. The overhead Cam models bury to valve stem deep inside the head.

Good practice would be to replace all seals at same time, but 1 cylinder could be done independently. But you are usually doing 90% of the work to do 1 set of seals. If a V-6 engine do the bad bank completely.

Head gasket, oil circulates through passages. Requires removal of everything above the head so gasket can be changed.

Bad Oil ring on Piston. Requires removal of head, oil pan, possibly motor to access crankshaft.

There are some tests which can help tell the difference between the problems. Some of it is visual so you need some disassembly for that. This is not going to be as simple as changing a waterpump or an Alternator. But the valve stem seals are reasonable and the head gasket is not so bad.

Can not say what labor will cost, but it will be probably 80% of the bill.

Gentlepersons... have 1992SL1 engine died... gong to replace it ,,, but all involved want to know engine type dual cam? vs ? ... can you tell me how to determine whats in the car now.. vin# nails it...


That is pretty easy. If your Saturn is an SL1 it is single cam if it is an SL2 it is dual cam. That is the only difference between an SL1 and an SL2 - Saturn didn't even bother to put a tag or emblem anywhere on the body to differentiate between the the two models. The 8th digit in the VIN will confirm this for you. If the 8th digit is "7" it is a Dual Overhead Cam (DOHC) engine. If the 8th digit is a "9" then it is a Single Overhead Cam (SOHC) engine. When you have seen both engines, it is pretty obvious by simply looking at them. The DOHC cam cover is much wider and has 2 "humps" with spark plugs and wires going down the center between the humps. The SOHC cam cover is narrow and the plugs and wires go down one side.

Also in the 1992 model year, the DOHC engine was equipped with Multiport Fuel Injection. (MFI) The fuel injectors (4 of them) were located in the top of the intake manifold. The SOHC engine had Throttle Body Injection (TBI) The two injectors were located in the throttle body.

I don't have any pictures of the cam covers, but I have pictures of the cam cover gaskets (AKA Valve Cover Gaskets) you can very easilly see the difference.

Where is the camshaft sensor located on a 1999 Saturn SL1?


If you have the 1.9 SOHC, you don't have one. If you are getting an error code for a bad camshaft sensor, you either have a bad spark plug wire (#1) or corrosion where the plug wires go to the coils.
Swap wires from cylinder 1 to cylinder 2, and see if the check engine light goes away. (This is common on the staurn) If it does, replace the wire set.

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

What type of engine do I have in my 1998 Saturn SL1?


if it is an SL1 it has a SOHC 1.9L. Basically the same engine was in all saturns 91-99, just different heads. the Sl2 had double over head cam and the Sl1 had SOHC.

What's the difference bteween a 99' saturn sl and a saturn sl1? My 99' saturn sl wont go in reverse, what might be wrong with it?


The SL2 is a DOHC 1.9L and the SL1 is a SOHC 1.9L. They have different transmissions, the DOHC uses a 15 inch wheel while the SOHC has a 14 inch wheel. So when you are shopping around for another transmission you must get one from the same type of engine. Saturn auto transmissions seem to be problematic, I stuck with the manual trannys and had very good luck.

WANT TO PUT A 1996 LS -1 SATURN, MANUAL TRANSMISSION AND MOTOR INTO A 1995 LS-2 SATURN BODY AND CHASSIS. WILL I HAVE TO CHANGE THE COMPUTER? DOES THE DESIGN CHANGE FROM 95 TO 96 EVEN MAKE IT POSSIBLE...


There isn't much difference between them. The SL series didn't change between 95 and 96 except for the ecm is OBD2 on the 96. Are both cars stick shift? The difference in the SL1 and the SL2 are the cams. 1 for sohc and 2 for dohc. So what you are asking is can I take out my dohc motor and install a sohc motor right?

Does a saturn sl1 2001 have a single or double transmission?


An SL1 has a single overhead camshaft, SOHC, engine. It has but one transmission. If it has a clutch pedal next to the brake pedal, it is a manual shift/transmission, if there is only a brake pedal, then it is an automatic transmission.
