Update on the classic Rover 2000 in the workshop recently with a bit of a list: overheating after 15 minutes, a misfire, and wipers that weren't playing ball.

​Classic cars usually mean chasing down a few interconnected issues, so we started from scratch:

​Engine & Tuning: Compression was good, but it was running very rich with an oily rear cylinder. The carb was way out of tune, mostly caused by an old, blocked air filter. Fitted a new filter, retuned the carb to spec, and repaired a vacuum leak on the brake booster.

​Electricals: Tracked the wipers and brake lights back to missing live feeds in the loom, so we sorted the wiring and renewed the feeds.

​Valves: Checked the valve clearances and found all exhaust valves out of spec. That explains some top-end noise, so it’ll need shimming down the line.

​With everything set up, we took it on a proper 22-mile test drive up over Brent Knoll to put it under load. It ran spot on—no overheating, no misfires, and gave us a good excuse to stop for a milkshake on the way back.

​Good to see classic iron like this back on the road and running properly.

​The customer brought it in noticing a distinct loss of power up hills and under hard acceleration. On these engines, the first suspect is usually wet belt breakdown causing oil starvation.

​Here’s how the investigation went:

​Initial Diagnostics: The code reader gave a totally clean bill of health.

​Test Drive: Hesitation was clearly there once you crossed 3,000 RPM.

​Live Data: Monitoring the software showed the inlet and exhaust camshaft positions were reading out of range.

​Because belt degradation can block the oil pickup, we checked the dephaser solenoids and dropped the sump to inspect for debris. It was surprisingly clean (around 10% restriction), so we cleaned everything, refilled with the correct spec oil, and dug deeper.

​We stripped the top end and verified the physical timing was spot on. Before putting everything back together, we swapped the inlet and exhaust cam sensors to see if the issue moved.

​Sure enough, the live data shifted straight to the other side—confirming the sensors themselves were failing. Two new cam position sensors fitted, and the car was running smoothly again. 📈

​(To top it off, the starter motor unfortunately gave out two days later! We got it confirmed and swapped out the same day to get the customer back on the road.)

Little KTM390 came to us after it left others scratching their heads. This much lived KTM 390 was misbehaving in 4th gear. Under acceleration it would bang and hesitate. With gear position sensors and selectors already exchanged it was obvious to us that the issue was deeper routed. So we pulled the engine and stripped it down. Finding that the selector fork on the countershaft was visibly worn to the point that the contact plates were missing. We removed the stacks and found the issue. Due to the selector ware 6th gear that interlocks into 4th when selected was partially engaging due to the worn selector. Replacement parts including 6th, selector fork, bearings and full replacement timing gear fitted. We also Re-shimmed the valve train whilst there.

Lesson learned - buy cheap buy twice!

Bangernomics - the pursuit of running a cheap car as cheaply as possible!

Ant was working on his "bangernomics" Discovery 3 again this week. Needing to replace the ancient and brittle diesel injector leak off pipes. Pleased with himself to have found a set of less than £20, which is a saving of nearly £200 on the genuine item. The late shift in the workshop turned into the late shift from hell.

On the face of things they looked great and virtually identical. However fitting was a different story. The ni***es were not chamfered, the O rings are over size and even once those issues had been overcome it then became apparent that their joints had been assembled incorrectly, meaning they absolutely wouldn't fit!

So a genuine set was ordered at 1am when he finally got into bed.

Will certainly think twice before buying the cheapest next time

Classic Rover 2000 in for a tune up and Diagnostics for poor running when hot. Andy's working his magic and already made some headway.

As the owner and previous shops have had a go already, we have had to start with the basics and work our way through. Compression test, ignition system and then air and fuel.

Looking forward to updating soon with our findings.

Lovely Mitsubishi Evo 9 in for a check over, slow start diagnosis, Mud flaps fitted and Tial Blow Off Valve fitted.

Started the diagnosis of the sluggish starts with battery voltage test ✅, cranking voltage test ✅, parasitic drain test ✅ all passed.

On cleaning the battery terminals, we found they were slightly loose and noticed the relatively new battery was only 330 CCA (Cold cranking Amps) and a car of this size should have a battery CCA of over 400. A new battery to correct spec advised.

The car is fitted with a MOTEC ECU and in the absence of an access key we couldn't check the starting protocols

Fitted the Ralliart mud flaps and Tial BOV and returned to the customer same day.

We look forward to seeing more of this future classic for some preservation works!

Quick check over for this fiesta. Came in with an unusual suspension noise. Quickly diagnosed as the near side front lower control arm. The joint is worn and was making a nocking noise through the suspension. Quickly sourced the part and replaced it.

Audi A1 with non functioning steering wheel controls and air bag warning light. Simple diagnosis on this as it's commonly the clock spring behind the steering wheel. Confirmed with a quick scan. Simple job to replace but unfortunately on these Audi's they are not the cheapest of parts. Replacement item fitted and correctly coded in!

Ford Ranger in today for repair of a couple of issues previously diagnosed.

First up was an unusual whistling noise on acceleration. Whilst only present when driving it was an interesting one to diagnose. Whistling on a turbo car is usually related to a boost leak on the intake side (cold side) of the turbo. After testing for leaks with various methods and repairing a faulty EGR valve which was cracked the noise was still present and surprisingly worse! We then found that under certain boost conditions the exhaust was blowing from a joint that's meant to be sealed with a metal gasket. The metal gasket was actually acting like a reed on an instrument! This was only possible due to warped exhaust flanges. We filed both flanges flat and replaced the gasket.

Second issue was a diff output shaft oil leak. Replaced cleaned up and renewed the oils.
