“The part doesn’t exist any more.” Usually, it does. How CRS 3D-scans, reverse-engineers and remanufactures obsolete conrods, cranks and components in Durban — bringing dead engines back to life.
Why you can’t just weld a cracked block, how the century-old cold repair process actually works step by step, and why a stitched casting keeps its shape — and its machined faces.
A leaking exhaust manifold warps aluminium heads and cracks cast iron ones. Here is the damage pattern we see on the bench, and why we measure before we machine.
Three words that get used interchangeably — and shouldn’t be. What each actually means, the seven questions to ask any engine shop, and how to compare quotes like-for-like.
Worn bores, a block at its final oversize, or one badly damaged cylinder — the decision tree we use in the workshop, in plain language. And why a “scrap” block almost never is.
Most shops condemn a cracked head on sight. How cold metal stitching permanently repairs cast iron, how aluminium heads are welded and re-machined — and when replacement really is the better call.
Bearing knock, low oil pressure, scored journals — does the crank need grinding, rebuilding, or replacing? How we decide, what each route costs in rands and downtime, and when a “scrap” shaft can still be saved.
