This TDV6 L405 was recovered in recently being diagnosed as potentially needing and engine.

After a quick look in the yard we suspected it had snapped a cam pulleys. And after a bit or disassembly it was confirmed

Luckily the other bank of the engine was not damaged. We confirmed the cylinder integrity was ok by performing a leak down test by injecting compressed air into each cylinder and measuring its rate of leakage. All passed 👍. We could see nearly all the rocker followers were damaged also so initially thought it was best case scenario considering what had happened.

But after careful checking over the top end of the damaged bank we noticed the cam caps to look elongated. This was confirmed with a set of snap gauges. Snapping them at what looked the stretched area and finding them lock up when rotated 90deg. We then checked the cams which were also slightly bent

So it’s had a new head, all followers, cams. Cam chain kit, inlet manifold and full timing belt kit with the new modified Ford pulleys we have installed as soon as they came available.

The route cause, The weaker pulley? Yes. The local main dealer using felt tip instead of locking the crank with the correct tool? Yes. But overall the x3 m8 bolts which were torqued upto over 110Nm. (Roughly 4 times what they should have been) Yes that would have done it as the hub of the pulley was deformed under the stress applied by the bolts.

All back running and rebuilt correctly using a torque wrench and correct engine locking tools. It wasn’t rocket science. 🙂‍↔️

What’s the point in spending all day fixing them if you don’t get to play with them. Last Friday the team went to Land Rover experience Peckforton for a day’s hospitality experience. The morning was spent in a P460e L460 Range Rover and the afternoon in the awesome Defender Octa. Although the average of 7mpg crawling round the quarry was noticed 😜

June had been another busy month as usual.

Chains, turbos, diffs, oil coolers, inlet manifolds, coolant pipes to showcase a few. 👍

Another victim of sunroof drain failure. Both drain ports on this L494 were blocked solid and one side had completely rotted off.

The car was booked in with an E-Diff failure on the dash and when we inspected the module it was dripping in water.

The drains were cleaned and repaired, and a new Diff module will be fitted and programmed.

We check and clean when necessary these drains every service on L405/494 models due to them blocking. It can save you a lot of money in the long run 👍

Its quite rare we see L320 sports nowadays but luckily the ones we do see are all very clean.

This one is by far the cleanest. Having only covering 24k miles its a credit to the owners and workshops that have looked after it.

Up in Cheshire all the way from Guernsey and popped in for a quick repair of the gearbox paddles and fridge installation.

When is a faulty wire not a faulty wire……..

This Disco 5 came in initially for a engine management light but when dropped in we were asked of we could also investigate the SOS warning on the dash and the radio intermittently not emitting sound.

The EML was a straight forwards job. The SOS was logging faults with the internal microphone and call button both being shorted to ground. These items are both up near the interior light and are common failures when a windshield has leaked, but this wasn’t the case. Going off the fault descriptions the manual suggested it was a wiring fault. It would also cause the intermittent radio failure as when the SOS system is in operation the infotainment system is muted. And as the car thought it was nearly continuously in operation this confirmed the last customer concern.

All Components were checked as well as the wiring which were all fine. The last part of the system was the Telematics module (TCU) which is basically the car’s modem connecting it to the internet and other services. It has several functions but one is its ability to remotely start the car from the JLR app.

This being so it makes the module part of the cars immobiliser system. With us being SERMI approved we were able to program a new module and get the car back on the road.

2023 L460 for all brakes, rear tyres and front wipers…… can anyone comment what’s special about the wipe blades on the new shape Range Rovers?

Unfortunately the world if full of those who aim to achieve gains without the effort the rest of us put in.

Just seen this post on a selling page i was a member of. Its a recent post of ours altered and claiming to offer a v6 engine for a pittance. Clearly a scam, even worse is the account posting it is the pages admin.

Reported to Facebook who have done nothing so please jump on this a report as many times as you can to get their account and fraudulent page disabled

We believe in using the best parts for the job.
Sometimes this means not having them available the same day…...

We had a situation when 3 defenders were presented within a couple weeks of each other,all needing transmissions. Having been bitten in the past with alternatives we gave the customers the option of using the best and waiting for it or an off the shelf alternative. The first customer was without their family car and opted for the off the shelf option purely to keep mobile. Well, when it came the next day it was found to be far from suitable to be fitted in any vehicle so was sent back. This was disappointing for them as well as us but cemented the fact that not all reconditioned units are the same.

Fast forward a few weeks and winchestergears delivered a box full of beautifully reconditioned units. One R380 and the MT82 were fitted the same day of delivery to the two immobile cars that were ready stripped in the workshop. Both fitted with LOF Clutches - Heavy Duty 4x4 Clutches and a LOF output shaft on the MT82

The remaining R380 and transfer case being fitted this coming week on the the last car that was able to keep limping about on its factory fitted unit after 170k miles.

Black discovery? Yeah completed it mate 😝 5 snuggled up in the workshop last night. And a brace of defenders.
