Crank shaft vry hard to turn by hand with belts off timing betl and marks are perfect


Mr. CORNEL, according to what you have said, one thing is possible,with oil level ok,battery good, means that the problem you face is that the Oil Pressure Pump lost the pressure strength and cause the Crank shaft as not enough Oil to get lubricated sufficiently,cause the crank and rod bearings to seized on the crank shaft and that's why you do have hard turnings. In other words the engine seized and must call you mechanic to help and advise. The Red Light blinking before was the warning to that something was wrong with the oil pressure.

Why does my low oil pressure light comes on when making left and right turns


Oil level is probably low. When you turn, your oil splashes to the right or left and your pump is not able to pick up the proper amount of oil to pump. If the level is proper, you might have the wrong grade of oil. Check your owners manual for proper weight for the driving sonditions you are in.

Oil light will only come on when the sensor does not detect oil flow.You may have a circulation issue not allowing oil to return to oil pan quick enough to keep up on motorway. Have valve covers removed and check for build up at oil return ports in top of head(s)

High pitched noise at highway speed


I also have a 2005 Tucson. It makes a loud whistling noise when approaching 75 mph. It comes from teh top of the windshield. I had the windshield replaced and thought it would solve my problem, but no. I should have had it fixed when warranty was in effect but I don't drive that fast much. I also need hlep.

What does the 15000 mile check up on the 2008 Hyundai Elantra cover?


A complete check-up of the car which should include but not be limited to:
  1. Change the oil (when was the last time you changed it?) Change the oil filter & the air filter (again, when were they changed last?)
  2. Check the coolant and brake fluid
  3. Check the brake pads - inspect all lights including turning signals (for safetys sake)
  4. Check the air pressure in the tires (including your spare tire) Check your car's alignment, this can cause uneven wear on your tires and it will believe it or not contribute to making the trip more exhausting.




Make sure you get a good rest the night/day before you depart. - if you begin to doze off dont hesitate to stop at a rest stop. Dont fight against your body, if you are tired, stop and take a 30 minute power nap, wash your face and drink a cup of coffee before you get back on the road.
Make sure you have a bottle of water in the car and plenty of good music to listen to. - Speed wise I suggest you dont travel at more than 10mph over the speed limit, traveling a little over (up to 10 mph) is tolerated by police, but I strongly sugest going 5 mph over the limit, set the cruise control and enjoy the trip without worrying about potential fines. If you do the math, the difference in time traveled is not so great:
speed limit = 70 mph (just as an example) 1300 miles @ 70 mph = 18 hours 36 minutes 1300 miles @ 75 mph = 17 hours and 20 minutes 1300 miles @ 80 mph = 16 hours 15 minutes the difference between traveling 75 or 80 is only 1 hours and 5 minutes. Not worth risking a fine for

A fairly consistent tapping noise from the top of the engine between 50 - 70 mph. After 70-75 mph in seems to quiet down.


sounds like a lifter is bleeding out or starving for oil at low revs
check oil level and oil pressure
if thats good lifter or tappet clearance next to check
is engine seviced regularly?
slugde build up can cause problems also
if V6 petrol see a lot of worn valve guides causing noise worse when warm and noise comes in and out at 1200RPM
tappet clearance issue noise would be there all the time
lifter can also come and go while holding revs up

My car is making this weird knocking noise and people tell me its the timing chain it wont go over 40 mph now it drove fine till i had it out one day and it lost power and started knocking it still runs...


The rod knocking is caused by loss of oil pressure. Did the oil light not come on? That light is red, red means stop. Do not start this engine again until the problem is corrected.

Have you checked the oil level?
