Serious engine knock or valve train noise. Have this looked into by a pro.
What causes a hard rattling knocking sound under the hood when you start your 98 ford windstar? Lack of oil, lack of oil pressure, badly worn camshaft or crankshaft or a combination of all the above.
Most common culprit is a slipping belt.
something might be lose under the hood u might want to get that checked out there could be something wrong with ur car how good is its condition
When it makes that noise it is either because your reving it to high or just because your engine is goin
It depends on the nature of the noise.
check your water pump,check all your pulleys make sure their bearings are ok
If the whistling noise is coming from under the hood its your belt, that's what's wrong with my Sequoia. If its not coming from under the hood its probably a crack in the seem of your window.
Most likely it is coolant getting to hot and boiling over, car is most likely overheating. Check for fluid under car, and temperature gauge.
There is a baby under the hood.
We need some more information to have a chance of hitting this one. Could be a cat under the hood, could be a clogged oil pump, oil, bad lifters or???? What kind of car and what engine? How many miles, and any recent maintenance? how long does the noise last and what does it sound like?
What causes ticking, check engine light, and the check gauges sensor to come on in a 1999 Dodge Durango 5.2L SUV?
