What's your oppion

No this is a bullet proof engine, but things like this do happen from time to time.

plug your car in so oil can stay worm then it will not noke only have plug in for 10 or 15 min

ionMr. Hugo. what to what you do have is the viscosity of your engine oil. Most probably is either long mileage used engine oil and due to that oil mud built up inside the engine, in the oil pan and most likely close to the oil pressure pump filter reducing the suction and that is why you do have cold lifter knocking,as the engine oil that time is thicker and when it gets hot become thinner and lifters stopped knocking. My persona advise do flush the old engine oil using ( RESTORE MOTOR CLEANER ) pour it into the engine old oil,start the engine in idle and few times reving it for 40 minutes. Then drain it and renew the engine oil with new and recommended engine oil for your engine,by renewing the oil filter as well. Also in the new engine oil put also (RESTORE FRICTION REDUCER ) additive and run the engine.For next oil change please do it every 5000 km ( 3000 miles)

SOUND'S LIKE YOU COULD HAVE A BAD ROD OR CRANK OR LIFTER.TRY THIS CHECK YOUR WATER AND OIL NOW START THE ENGINE IF IT IS A FAST KNOCKING HOLD YOUR FOOT ON THE BRAKE AND PUT THE CARE IN GEAR IF IT QUEITS YOU HAVE BAD ROD SERIOUS MOTOR REPAIR INTERNAL.DO THE SAME THING AGAIN AND IF IT IS MORE A THUMPING NOISE AND A SLOW DEEP KNOCK THEN WITH THE ENGINE IDLEING PUT IT IN GEAR HOLD THE BRAKE GIVE IT A LITTLE GAS AND IF THE MOTOR KNOCK'S GET'S QUEIT IT'S POSSIBLY THE CRANKSHAFT ANOTHER INTERNAL PROBLEM MOTOR OVERHAUL IF IT'S A FAST RATTLING IT'S PROBABLY A LIFTER STUCK OR BLEED DOWN DIRTY OIL OR A WEAK OIL PUMP ALL ARE BAD NEWS SORRY.GOOD LUCK

check rocker arms and lifters sometimes lifters get stuck until they fill with oil. partially collasped lifter may need cleaned .

Your problem could be a lifter that's either pumping up or leaking down which wouldn't be evident when you check the rocker arms for play with the engine off. You can use oil deflector clips and a mechanic's stethescope to run the engine with the valve cover removed and isolate the lifter in question. If you had a bad head gasket and had coolant leaking into the oil, it's also possible that you're mistaking the sound of a bad rod bearing for a lifter noise. Hopefully it is just a bad lifter.

It sounds like a weak lifter. When the oil is down 1/2 quart, add 1/2 of dextron ll instead of oil. This will help fill the lifter so it won't collapse again. Also look down the hole when you take of the oil cap and make sure it isn't filled with engine sludge. If you see some, get it cleaned out by a garage.

Pour in some engine cleaner and run for 4-5 min, this should free up the lifter. Drain the oil and install new filter and oil. You may have to do this 2-3 times over the next month just to clean all the gunk out.

I would not believe any thing some parts store loser told you. Theres not a V8 built that doesnt have hydraulic lifters, unless its some fancy racin engine. It has hydraulic lifters, but unless you dont change your oil every 5k miles and/or use some cheap oil, there should be no problems. You should have a real mechanic look at it, and verify that you have good oil pressure. If it does, I would change the oil and use some MOBIL 1 and drive it, the oil will clean the lifters somewhat. If the eng has low oil pressure, that will need to be addressed.

These engines were overhead cam.If you did put the oil back in as you said and the noise went away,no initial problem.The noise from the lifters, if its still there, is a ongoing problem.Maybe just an adjustment of the lifters needs to be done.Hope this helps
