What is my torque number for my 99 aurora I am replacing my cam shaft

The torque specification for the rocker shafts on the 2001 Hyundai Accent with the 1.5L single overhead cam engine is 18-20 lb-ft. The proper torque sequence is as follows:

1. Tighten the bolts to 8 lb-ft in a crosswise pattern.
2. Increase the torque to 15 lb-ft, again in a crosswise pattern.
3. Finally, tighten the bolts to the full torque of 18-20 lb-ft, again in a crosswise pattern.

Make sure to use a torque wrench and follow the sequence carefully to ensure proper tightening and prevent damage.

Torque setting Toyota Land-cruiser 80 Series 4.5 1995-98
Engine code: 1FZ-FE, 1HD.
Stage 1: 20 Nm (Start tightening bolts from center to outwards)
Stage 2: 39 Nm
Stage 3: Rotate each bolt by 90 Degrees.
Stage 4: Further rotate each bolt by 90 Degrees

There are no timing marks.There is is a slot in the end of the cam shafts.With number one cylinder at top dead center use a metal strip to align the slots and torque the cam cap bolts.CAUTION !! Torquing the caps when number one cylinder is not at the top may bend valves.

My manual shows an 8RC for 70 and 71 and an 18RC for the 72-74

18RC valve clearance HOT IN .008 EX .014 cold spec. .007 .013
Cyl head 72-82 Ft Lbs
Rocker caps 12-17 ft lbs
cam bearing clearance .001-.002
cam endplay .0017-.0066
oil tube 11-16 Ft Lbs

most likely the torque specs are the same as the other model engine that is in your manual just be sure to tighten them slowly and equally back in forth in small increments because those cam shafts can snap very easily

If you are asking about the cam shaft bearing caps, the answer is a most definite YES! I can't remember the exact measurement but believe it should be 12nm.. When bolting down the shafts, hand tighten each cap, pulling the shafts down evenly and then when all caps are fully closed use a torque wrench to complete the job. Regards John

4.3 liter, right? I think you have it right--see pic below. So it cranks but no fire happening? Did you check firing order, etc.? Getting sparks? Fuel pump coming on? Injectors firing? If you had the engine out of the car, make sure you got all the ground wires back in place, etc.

Hi, i would check the thermostat first unless the water pump is leaking as the water pump is where the timing belt is is the timing belt needs removing to get to the pump, take the thermostat out and place it in a tub of boiling water and check if it opens up if it dont then it will need replacing.

you need to bare in mind that it could also be head gasket failure so make sure you get this tested if the thermostat is found to be in working order.

let me know if you need further assistance ok

According to my parts guide, the fuel pump for your 97 Olds Aurora fits only that and the 97 Buick Riviera's and nothing else. The pump for a 99 Park avenue comes up as a different part number. Hope this helps!
