Use oil burning sleeves from any auto parts store, the screw right on the plugs, and hold the spark plugs out of oils way.

also check PCV valve and hose for clog. if they are clogged it will cause oil to burn in the cylinders. keep me posted

Where are the spark plugs located?

Well, first of all, if you are asking for help with your vehicle, it would be really helpful if you would take the time to mention WHICH ENGINE your 2003 Bravada is equipped with. This makes a HUGE difference in the answer you will receive.

There is a 4.2L inline 6-cylinder as well as a 5.3L V-8 engine available for a 2003 Oldsmobile Bravada. Two TOTALLY DIFFERENT animals!

The spark plugs for the 4.2L engine are located in the TOP of the cylinder head under the ignition coils. This requires removal of the intake plenum to access them.

The spark plugs for the 5.3L engine are located on both sides of the engine in the SIDE of the cylinder head between the exhaust manifold ports. (PLEASE ALSO SEE PICTURES)

Where are the spark plugs located on the 98 oldsmobile bravada?

On a Bravada, the engine is positioned so that you have 4 cylinders on your left and right in an 8 cylinder, and 3 on each side in a 6 cylinder. If you look on each side you will see separate valve covers, About 4 inches below these covers are where your spark plugs go in. They will be between your exhaust pipes, where they mount to your engine.

00 bravada turns over but wont start. Just had tune up fuel filter change. They said they checked fuel pressure and was good. Could it be coil?

If you want to check to see if you are getting spark - remove a spark plug and reconnect the plug wire. Be sure the plug is grounded to a good ground on the engine and try to start the eng. If there is spark seen at the electrode of the spark plug then it is not your ignition system (as far as spark goes) If you do not see spark it could be your coil or possible your ignition module (in distributor) I'm guessing you have an ignition mod - you do not mention the eng you have.

Does the bravada have spark plug wires going to the spark plugs


Would recommend that you go to your local auto parts store and get a Haynes Manual for your vehicle type. The manual would have all the information you need for your particular vehicle.

Hope this helps.

New spark plugs gone out

If the odor is not heavy gasoline, then they appear to be oil fouled. The cheap fix is to buy at any auto parts store oil burning plugs or sleeves, these will keep the spark plugs slightly further out of the cylinder, out of the oils way, and should provide a reasonable resolution.

Check the PCV valve and hose, if they clog they will cause oil to enter engien cylinders. keep me posted
