i have a 95 ford ranger 5 speed with 240,kkk miles when i start it idles low and rough and makes a lould noise sounds like its comeing from the valve cover?? i was told could be lifters does anyone know

 

What is low idle RPM?

low RPM = low oil pressure

240k miles = larger gaps in bearings so lower oil pressure in general

lowest oil pressure in any engine is at the valve train, gravity.

If noise if gone at 700 RPMs(and up) then noise if from lack of oil pressure, fix the low idle issue

But I would pull off the valve cover and check clearances in valve train

 

Ok and the noise don't go away when I'm drive and no low idle but when I stop it try's to die but don't it shakes a lot when just idleing

 

I fixed the idle problem it was just a burnt vocuum line but the noise don't seem to be comeing from the value cover sounds lik it's comeing from the bottom of the motor in the front

 

Timing belt and/or tensioner could be causing the noise, loose belt will hit the cover making a metallic sound

 

Ok so I take the cover off then start it to see what the noise is? And how long can I drive with the noise. I don't want to break down on the side of the road

 

What did you find as far as the noise??
Did it go away with cover off?

My crystal ball is off-line right now so best I can say is, an engine can break down anytime, but with an unknown noise it might be sooner than later.

 

I believe I have the same issue with the vacuum line.

what exactly did you do to fix it OP?
