What does base circle area mean when doing a valve job ?


Base circle is the camshaft lower diameter where the lifter rides before the lobe starts to come into play.
The Lost Art of Valve Adjustment
Your second question depends entirely on the engine in question.
On a pushrod V8 the oil usually is metered by the valve lifters and goes to the rockers through hollow pushrods; a few drops of oil are released by the lifters during each valve stroke. Until full oil pressure and warm oil are in all of the oil passages, the oil to the rockers will be less than that of a warm running engine. The rockers really don't need huge quantities of oil, it is a lot harder to get oil to the valve stems.

You may want to make sure you have good oil pressure and the valves are properly adjusted [even on a hydraulic lifter system there are limits to how much the lifters will self adjust].

If you have an overhead cam engine, you will need lots of oil on the lifters and cams.

My 2006 Pontiac Torrent lose power when I reach the speed of about 75-80


That is an odd bit of advice. If the oil pump was working poorly enough to cause a noticeable difference on engine performance, then you have already ruined the engine.

Although not always the case, typically if you are losing power as you increase speed, it is a fuel problem. Fuel pump could be going out. Inline fuel filter could be dirty and restricting fuel flow. Intank (gas tank) filter could be clogged and restricting fuel flow.

Regarding your oil pump, you can check to see if it is working correctly by installing an oil pressure gauge. You might check to see if your engine has solid lifters or hydraulic lifters. If it has hydraulic lifters, your engine will develop a tapping noise when the oil pressure is low because the lack of oil pressure creates a lack of hydraulic lift in the lifters and so they collapse creating a gap between the lifter and the rocker arm. This gap means that the rocker arm comes off the lifter and then smacks the lifter when coming back down resulting in the "tapping" noise mentioned.

Bad oil pump knock


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)

1995 jeep yj 4 cyl manual tran, motor noise, taping, when oil is hot.Changed lifters, still noise, 200.000 km on motor


Two items that are important here.....Did you check the rocker arms for wear and did you check the camshaft to make sure the lobes aren't worn? Also, even a new lifter will not function correctly if the oil pressure in the engine is low. An engine with 200k on it likely has some bearing wear. The oil pump can also wear but generally it won't wear enough to lower the pressure enough to cause lifter noise. If everything in the valvetrain checks out as good, I'd be looking at the bearings. If some are worn (check with plastigage, available at parts stores) replace them and also the pump.
Most times, the rod bearings wear faster than do the mains. You can do rod bearings in the car. If mains are worn, best to do a complete rebuild as cam bearings are likely close behind, and mains should be done out of the car anyhow. (doubt if you will need to go that far though).

An engine is usually not permanently damaged by running without oil for a minute or two. They are often run with no oil pressure for 10-15 seconds every time the oil is changed. It's never really good to run them without oil, but it doesn't usually hurt them if it's only a minute or two. Hydraulic lifters, however, do pump out quickly and make A LOT of noise. If the oil pump fixes the oil pressure problem, you should be fine. Obviously I can't guarantee it, but if it was only a minute, I'd give it much better than a 50/50 chance -- I'd say it is probably more like a 95% chance you'll be fine.

Afer being driven 5-7 miljes my 99 tauras loses


I would have to say your engine is probably shot. The bearings are probably gone. It is possible, i suppose, that your oil pump is faulty. As soon as the oil warms up, and becomes thin, the rods and lifters start to rattle. The same goes for the oil pump, as oil becomes hot, and thin, it may not be pumping properly. I would try a used oil pump, and see if there is any difference before i wrote the engine off.

89 Ranger 2.9L 150k mi. Lifter noise, power lose, oil pres zero


the lifter noise might have been a bearing going bad or a piston ring. if you lost power you probably lost compression on one cylinder. Try checking your compression with a compression tester screwed into your spark plug socket. here is a site with a procedure.
