Pressure Tester

Cylinder Head and Block Pressure Tester

Award winning design. The most reliable and complete crack testing method includes heated and curculated in line system with air pressure. This method will find cracks that Air testing will not find. The system is very fast and can pressure test Automotive & Diesel Heads and Blocks.

Pressure testing is very profitable. 1 Job per week pays for the equipment.

The Newclear Pressure Tester is a revolutionary new machine that has been specifically designed for the automotive engineering industry. It has the capability to effectively test various cylinder heads and blocks e.g. a single Honda cylinder head, a Cummins 350 big cam block or a cummins NH block.

The main features of the Newclear Pressure Tester are one of total visibility through a transparent pressure plate with a 360° rotation capacity as well as an adjustable center of gravity to allow rotation of either a cylinder head or block to take place with ease. It is a complete unit with the added advantages of an in-line heater system which can provide hot and cold hydraulic testing capabilities and a quick set-up time.

Clear visibility.

Simple and quick set up time.

In-line heater system for hot / cold water testing.

Universal side clamping system.

Complete rubber blanking-off element kit to suit most cylinder heads / blocks.

Adjustable center of gravity for ease of rotating cylinder heads / blocks 360°.


All Cylinder Heads and Blocks should be pressure tested especially the “Cooked” ones.

With today’s modern Multi-Valve Light weight, high output Aluminium Cylinder Heads with
Cast Iron Blocks, it has become essential to have a good quality hot and cold
Hydraulic Pressure Tester.


Eliminating Comebacks

The customer must be confident that the “Problem” has been positively identified.
Major Piston manufacturers and Cylinder Head Gasket manufacturers that have been consulted have confirmed the need for High Quality Pressure Testing to take place when an engine is reconditioned or remanufactured.

With the great difference in Expansion Rates between aluminium, cast iron and modern light weight design, it has become essential to have a High Quality Pressure Test done in order to detect Fractures and Porosity in cores.

Tests have proven :

that some cores only fracture on disassembly and not when the engine overheats,
that some fractures are only evident after a Cold Hydraulic Test, then a Hot Hydraulic Test followed by another Cold Hydraulic Test. It is important to note that these three tests have to be carried out in rapid succession – 10 minutes maximu

Frequently Asked Questions

Q: Can you pressure test blocks?
Yes – System has an adjustable centre of gravity and special safety clamps to make
rotating of blocks while pressure testing, safe and simple.

Q: Can you pressure test V Heads?
Yes – All angles.

Q: Can you pressure test Cat Heads?
Yes – Maximum length is 1200mm

Q:Do you have to pressure test all heads in a hot condition?
No – Most cracks are easily indentified using cold water and air pressure
but the hot water facility is always available.

Q: Are you able to get spares?
Yes – Loose spares are always available.

Q: Should you have an unusual head (very uncommon) how do you pressure test?
We can custom make rubber blanking elements – but over the years we have added most
blanking elements that should be required.

Q: Does a qualified man need to operate the machine?
No – the system is very simple and one can be guided, with the supplied workshop manual
and the training video.

Q: Who uses this machine?
All big and small automotive rebuilders who need to identify problem heads and eliminate comebacks.

Q: Why do we need to pressure test?
To give a professional service and eliminate comebacks which means a loss of profit.

Q: What if there is a leak in the oil gallery?
Some heads can be repaired – most are then scrapped.

Q: Can the machine be used in a production line environment?
The machine can be modified to suite some production lines.
