Border Rivers Cylinder Heads

Knowing your value.
I have given a lot to the thought of why I started the engine shop recently.
I did it to better my life and that of my family. I have come to the conclusion that just taking people's words for face value is an alarmingly inaccurate method of judging both my own value and my family's, let alone theirs. People will and do lie and cheat to advance their own position, and in some case even threaten others.

As part of this value, and after a few rather dodgy warranty claims over the years of operation, and a lot of people that "know how it should be done", I have formalised the process of how I assess these claims. I have added this to the website.

A 12-month warranty is a 12-month warranty. If the spanking new engine sits on the floor for 8 months, that's 8 months of warranty gone.
If they put it in their pride and joy and drive it twice in those 12 months, likewise.
If they install a gearbox wrong and wear the thrust washers out in 5 minutes, the warranty goes into the recycling along with the oil and bearings - and they'll be charged for the teardown and inspection.
Here is a link to the full document:

12 MONTHS OR 50,000 KM – WHICHEVER COMES FIRST The engine assembly and its internal components supplied by Border Rivers Cylinder Heads are warranted against defects in materials and workmanship for 12 months or 50,000 km from the date of purchase shown on your tax invoice, whichever comes first. ...

And here we go for a comprehensive thread repair.
We set the cylinder head flat on the Rottler bed once the holes were clean, we then drilled and tapped a 14mm thread into it. We installed a bolt with plentiful retaining compound, cut and snapped it off similar to an oversized A plugin a crack repair, surfaced it flat, then traced the original centres and drilled and tapped it back to 8x1.25 thread.
All that times three.

In today’s episode of “How Bad Can Someone Screw Up?” we have this little beauty.
A reconditioned head came in for us to check out. This was one of the many issues. The shiny spot at the top of the drilled hole is the centre of the old broken bolt. The lower one was where I managed to remove the last of the broken bolt extractor.
They just left the mess hoping that the purchaser of the head wouldn’t notice.
