Exceptional Engine Work, from Crankshaft Grinding to Thread Repairs in Epsom | SRS Engineering

As you browse our website, you’ll likely come across a number of dedicated service pages, each describing how our trained technicians aid clients in Epsom – from private motorists, to trades and even main dealers. You may have an interest in cylinder reboring, curiosity about thread repairs, a passing fancy in crankshaft grinding, or questions on the ins and outs of an unleaded conversion. Or perhaps it’s other things cylinder related you want to get clued up on – cylinder head overhauls, cylinder head skimming or cylinder head pressure testing, for example.

But what if you want a quick, easy to read overview of these services and their particular differences, their particular nuances? As we don’t have one anywhere else on this website, we thought why not provide a service overview for both prospective and returning clients in the Epsom area right here…

Service Overview

Cylinder Reboring – Cylinder reboring is a process of restoring the engine cylinder to its original dimensions by removing a thin layer of material from the cylinder walls. This process involves using specialised machinery to remove any damage or wear, leaving the cylinder smoother and better able to perform its function of sealing the combustion chamber. An Epsom client may cylinder reboring this due to general wear and tear, excessive stress, or damage sustained due to an engine malfunction or accident.

Cylinder Head Skimming – Cylinder head skimming is a process of removing a small amount of material from the surface of the cylinder head to create a flat and smooth surface. Epsom residents may find it’s necessary after the cylinder head becomes warped or damaged due to overheating, which can cause leaks or other engine problems. Skimming the cylinder head can restore proper sealing and ensure optimal engine performance.

Crankshaft Grinding – Crankshaft grinding is the removal of small amounts of material from the crankshaft's main and rod journals to create a smooth, even surface. It’s a trusted repairs process that deals with damage or wear caused by normal use or engine failure. Crankshaft grinding can restore the proper dimensions and finish to the journals, restoring engine performance and longevity.

Thread Repairs – Engine thread repairs are essential when the threads in the engine become stripped, damaged, or corroded. As you’ll see over on our dedicated thread repairs page, they can be achieved via various methods, including helicoil inserts, time-sert inserts, or tapping the hole to a larger size and installing a larger bolt. Thread repairs can restore the engine's ability to hold fasteners securely and prevent leaks or other damage.

Unleaded Conversion – Unleaded conversions involve modifying an engine to operate on unleaded gasoline, which lacks the harmful lead content found in older fuels. This process can involve modifying the valve seats, installing hardened valve seats, or replacing the cylinder head altogether. Unleaded conversions are ideal for Epsom’s vintage car enthusiasts, whose engines are rarely built to tolerate unleaded. Resultantly, unleaded conversion can improve engine performance and reduce the risk of valve seat recession and other engine problems caused by use of particular fuels.

Cylinder Head Overhauls – Cylinder head overhauls see our engineers, who have over 50 years of accumulated experience, inspect the cylinder head, replace worn or damaged parts, and reassemble the head to ensure proper sealing and prioritise engine performance. It’s always spoke to the engine itself, but can include replacing valve guides, valve springs, and seals, as well as resurfacing or skimming the cylinder head. Cylinder head overhauls can extend the life of an engine and improve its performance, making it a valuable tool available to Epsom clients.
