CYLINDER

HEAD

Here at Trident Manufacturing we offer a variety of services for most petrol and diesel combustion engines. We have over 100 years combined experience in our workshop and have both new age and old school machinery to tackle everything that comes through our door. Below is a selection of our most popular Cylinder Head services.

CYLINDER HEAD PRESSURE TESTING

To aid you in deciding if your head needs to have the valves re-seated we offer a pressure test service. This is great in determining if the valves are actually the problem before re-seating them and that it is not a crack in the cylinder head itself.

The pressure test we service we offer costs €55+ vat.


CYLINDER HEAD RESURFACING

We offer cylinder head resurfacing for cars , vans , trucks , boats , heavy duty machinery … basically anything that has a cylinder head. We use state of the art machinery mixed with years of experience to give you the perfect end result. Cylinder head resurfacing starts from €55+ vat.


We can collect your cylinder head nationwide and ship it back to you if needs be (Charges apply)


CYLINDER HEAD VALVE RE-SEATING

What is the typical reason to have the valves re-seated in your cylinder head. The valves in your cylinder head are a vital part in the engine having the correct compression in the cylinder to run correctly and efficiently. This means if the valves are bent , out of shape , covered in carbon or other materials the cylinder will be leaking compression. This will then result in bad fuel economy, additional fumes / smoke coming from the exhaust , NCT emissions test failure , poor power and drive-ability.

We offer valve re-seating starting from as little as €70+ vat for an 8 valve model and €110+ vat for a 16 valve model.


CYLINDER HEAD TAPPET CLEARANCE ADJUSTMENT

We offer our tappet clearance adjustment service only in conjunction with the valve re-seating service we offer. This is required on non adjustable tappet cylinder heads. We manually adjust the clearance between the bucket and camshaft which means the engine runs correctly and at the most silent it can.

When you are getting our valve re-seating service done this will cost €40+ vat extra.


CYLINDER HEAD VALVE SEAT / GUIDE CHANGE

Often on cylinder heads that arrive into us for pressure testing or machining the valve guides or seats are badly worn or damaged. We offer a guide or seat change for €80 + vat.

  • The cost of the guide or the seat is included in this price
