Did you check the pressure first? Noisy tappets don't necessarily mean low pressure, sometimes they simply wear out.
Otherwise, either your oil pump is bad, or the oil pickup screen located inside the oil pan area is clogged up. Clean the screen first and then check the pressure...

On start up there was a load tappet noise (clapping) which faded away on my Renault Modus 1.4 16v, should I be worried ?


Wherever the engine stops at least a couple of valves will remain open meaning the maximum valve spring pressure is applied to those hydraulic tappets and a chance the oil will be squeezed out when the engine stands idle for a while. If a tappet or hydraulic lifter is lazy or the oil supply is low, it can take a while for it to recover when the engine is started.

Older VW and the older Ford Mondeo used to be particularly affected and sometimes could take 20 miles of driving before the noise disappeared.

There are engine oil additives designed to liven up lazy tappets.

Do they wor for noisey tappets


Noisy lifters (tappets) are caused by wear in the valve train, this is a fact of life for engines and normal. Two choices, go to the next higher viscosity oil(which will only quiet it a little), or have the valve train rebuilt. I personally have seen noisy engines run 10-15 years with no major failures!

Vw petrol 1.6 fsi missing on two cylinders


Tappet jacking is far from unknown but is rare and usually happens after a cold start when the oil pressure is momentarily much higher than usual.

The big question is, is the misfire caused by tappet jackiing with such a low oil pressure or is something else going on that coincidentally is causing the misfire? Perhaps some of the components used in the rebuild weren't suitable for that engine? I have noticed some engines have a second pressure relief valve fitted in the cylinder head, presumably to further reduce the oil pressure.

In 40-odd years I have only once known an engine that tappet jacked at any other time and new valve springs cured it.

The other big question that maybe should be answered first is why is the cold oil pressure so low after a fairly comprehensive dismantling and checking. It could be a case of going back to the drawing board...

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 major tapping noise from a 3lt diesel turbo toyota surf .constant loud tapping ,quietens with oil pick up a little. not a knocking just a tapping


lifters noisy,lots of miles on engine?as oil pressure gets higher and engine warms up(everything expands a little and quietens a little)it gets better,try fresh oil thats thicker for worn engines,and or check tappets(valve adjustment)if its applicable to this engine
