Put a good squirt of wahing up liquid into engine oil and half litre of diesel ,then run a while say 300 miles or so then change oil and use turbo diesel engine oil ,now if noise stops then just change oil every 6000 miles with a oil filter every third oil change.but if noise persists then repeat with washing up liquid and diesel and leave for a longer period ,your hydraulic tappets are gummed up from not changing the oil regular ,never mind these so called long life oils ---this is what happens when oil is not changed regular

Ticking & white smoke after replaced intake gasket


Sounds like coolant getting into the combustion chamber. Potential causes in order of significance: Intake manifold gasket (might not have been done right), Head gasket(s), cracked cylinder head, or, cracked engine block. Check the oil. If it looks like chocolate milk it means the coolant and oil are mixing

Oil leak on driveway coming from front of engine


Dear Sir,
Here is the oil leaking Problem Identifying Technique

Engine oil leaks from the valve cover gasket are common.

  • The intake manifold plenum gasket may leak and cause increased oil consumption/burning and a spark knock during acceleration; the gasket should be replaced.
  • External oil leaks from valve cover gaskets, intake gaskets (front or rear), and the rear crankshaft (rear main) seal area are common. The rear main seal is an unlikely source. Normally, the bearing cap mating surfaces (as well as the sealing surface between the oil pan and bearing cap) are the source for the leaks.
  • Engine oil leaks at the distributor can be misdiagnosed as leaks from theintake manifold seal, oil pan gasket, or rear crankshaft (rear main) seal. A revised distributor is available if oil is found inside the distributor.
  • If the oil filter casing shows signs of distortion from excessive oil pressure, theoil pump should be replaced.
  • Often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
  • Carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.

    Got ticking noise coming from the back valve cover right under the trottle body when the engine is about 1,500 to 2,000 rpm and then goes away. What it could be?


    You gotta remove the valve cover (its easy) and take a look at your valves to see if a spring has broken
    or other part (e.g. rocker arm) is damaged - before the head is irreparably damaged and needs to be replaced - which is what most garages will tell you to do with a pinging/ticking head.
    While you've removed the valve cover, consider replacing the valve cover gasket, which is a common
    place for an oil leak to develop.

    the knock sensor changes the timing of the motor when it senses knock ,it sounds like the wire may have come off ,it sounds as if when you press the gas the timing should advance and it sounds as if its not advancing thats why you are hearing a clattering noise on accelerating.if you keep driving it like that you can do engine damage

    I have a loud ticking under my valve cover. 97 ford escort. I think its a loose valve but is it some thing i can fix. I know a little about cars. but not an expert


    not a valve, but a lifter. I will paste procedure below. You judge if you can do it or not. Recommend you replace them all while you're in there. If you let this go, the lifter will wear out the camshaft. Lifters are $22 each, and you have 8 of them. You will also need a new valve cover gasket.
    Please let me know if you have questions, and thanks for using FixYa.

    If you have an adjustable valve train you may need to adjust the rocker arms. Remove the valve covers and look to see if there are adjusting nuts on top of them. If so, get a shop manual and a feeler gague and a couple of wrenches and screwdriver and follow instructions in manual carefully.
