Question about 2006 Kia Optima
Single cam 2.0 liter has a,b,cxwith pointer matching arrow on top of head [cam] cover.i matched cxpointer with timing cover arrow..>< wont fire,sometimes pops out intake system,distributorless system! so i cant just see rotor pointing to #1! So one step up and two steps back![sorry bruce] so few were made books are not available,yes a two year car,95-97 only had this engine, is crank and cam fired,i think?Greg asks? should i 180 cam?in reference to crankshaft? or just what? timing [valve cover says [lona]
Gregorykilke: your engine has several references if you are describing the same vehicle. The 1996 KIA Sportage has a SOHC engine and was the last year to use one before they went exclusively to twin cams.
The timing marks are as follows: On the crank, position the crank to where the woodruff key is in the 12:00 position. There is a metal plate with a notch behind the gear. If you look closely at the engine behind the plate, thought the notch, there should be a small "ARROW" which should fall within the notch. If lined up properly, the #1 piston will be at TDC.
On the top end of the engine, your cam gear is numbered 1-2-and 3. Position the cam to where the #2 on the gear is at 12:00. On the back side of that gear, should be a mark which should be running in line with the # 2 and it is the "Match mark which you line up with the small arrow or "V" on the cover.
A word of caution! This is an interference fit engine which means it BENDS VALVES IF YOU DON'T HAVE THE TIMING CORRECT AND YOU HAVE BEEN SPINNING THE ENGINE OVER!
IF>>>you are lucky, you might not have had the timing too far off and the valves may be fine, but exercise EXTREME caution when setting up the valve timing.
One way to avoid bending valves, is to make sure none of the pistons are at or close to TDC. This way, you can roll the cam in position and then watch which direction is going to bring the #1 piston up and whether it is rotating the engine clockwise or counter clockwise to bring the piston to that position , it won't harm anything. IF you feel any resistance at all STOP!!!!!! because the timing is off and you will bend valves.
Make sure the tensioner pulley bearing turns smoothly and makes no noise. DO NOT WASH IT WITH SOLVENT OR SPRAY IT OFF WITH CARB SPRAY! The solvent will get inside the sealed bearing area and contaminate the lubricant causing a premature bearing failure and a potential disaster for your engine!
Should you need further assistance on this subject, just ask and I'll do what I can to help. The belt tension is also CRITICAL!
Take care guy, Give the folks at FIXYA some input if I am doing you any good or if I have helped anyone else, write in and let them know. They want feed back. GOOD LUCK!
