A quick fix would be to change the oil and instead of using 5 quarts of oil then use 4 quarts of oil and a quart of lucas oil treatment

What is tappet settings


Hydraulic tappets are tappets that contain a small hydraulic piston, pressurised by the engine's lubricating oil supply.[5] Although the piston does not move appreciably or frequently, it acts as a hydraulic spring that automatically adjusts the tappet clearance according to the oil pressure. This makes the valve actuation self-adjusting and there is no need to adjust the rockers. Hydraulic tappets depend on a supply of clean oil at the appropriate pressure. When starting a cold engine, with low oil pressure, hydraulic tappets are often noisy for a few seconds, until they position themselves correctly.

I have a 2004 Toyota Tacoma. During the last 2 months when I start the truck in the morning I hear a "tac, tac, tac, tac ...." noise for 30s to 1 min than it stops when I drive away. This...


This is most likely a noisy lifter (or valve tappet). In cold weather, the clearances in the valve train open up because metal contracts due to the cold. Once the oil pressure comes up after start the noise goes away because the larger clearance fills with oil and the lifter becomes "cushioned" with the oil. The proper fix is to have the valves adjusted. I believe in your model, that is done by putting shims on the lifters. This will quiet the noisy lifters. In the short term, you can try using a lighter weight oil for cold weather. This will get the oil to the lifters faster after start up and quiet the tapping more quickly. Once the weather warms again, shift back to the normal weight.

Motor started tapping loudly as if there was no oil, oil level was fine, changed oil sound quieted after 20 minutes, sound came back a couple of days later, went away the last couple of days on short...


hi this could be due to your hydraulic tappets, these will start to rattle if the oil has been low at some stage and the oil was to thin this normally sounds worse in the mornings on first start and gets quieter as the day goes on or disappears altogether, what you could do, is use an engine flush, put it in the engine and run it for a period of time, then empty the oil and refill with a thicker grade oil and see how that goes..hope this helps

Rebuilt engine. when started again car ticks. timing marks aligned correctly, timing light shows 20 deg. what gives?


Most likely the hydraulic valve lifters, notoriously noisy in Mitsubishi engines. My 2007 Galant Ralliart Mivec 3.8 V6 with less than 15000 miles ticks also as did my 1989 Gallant and 1997 Eclipse.

Noisey tappets


Don't bother. They are hydraulic and rely on oil pressure to obtain a zero clearance when everything is OK. Your oil system may be sludgy or you may be using the incorrect viscosity oil.
