Frequently Asked Questions
From £5,900–£6,400 including fitment, ECU reset, road test, and 12-month unlimited mileage warranty. This covers the complete rebuild of your Ingenium AJ300 engine with updated turbo actuator LR072310 and timing chain kit LR096682 at our Billericay workshop.
With our specialized rebuilds, yes. We've rebuilt over 80 P550 V8 engines snce 2009 with reinforced valley pan gaskets (LR012345) and upgraded oiling systems specifically for track use. Our 12-month warranty covers performance driving, and we perform rigorous testing including 45-minute dyno runs with aggressive driving profiles at our Unit A5 Windsor Road facility.
Turbo actuator failure (LR072310) is the most common issue, particularly in models driven aggressively. The factory actuator wears prematurely under high-boost conditions. We replace it with the updated genuine part LR072310 during every P300 rebuild, along with ECU recalibration per JLR TSB-2021-08. This addresses the root cause rather than just clearing fault codes, which is common with general garages.
Yes - all Jaguar F‑TYPE 75 / R75 models require ECU coding after engine replacement. We use Autologic and JLR SDD tools to perform full immobilizer synchronization and adaptation at our Billericay workshop. This is critical for proper engine management, particularly for the P450 MHEV system which requires specific calibration. Our process includes verifying all systems communicate correctly before road testing.
Absolutely - valley pan gasket failure is the #1 issue we see on P550 models. We replace the factory gasket with the reinforced unit LR012345 during every V8 rebuild. Our process includes thorough cleaning of mating surfaces, precise torque sequence application, and verification of seal integrity. This is a common failure point after 60k miles, especially on track-driven vehicles, and we've perfected our approach over 75+ P550 rebuilds snce 2009.
It's a known issue, but manageable with our specialized approach. The Ingenium I4/I6 engines (P300/P450) can develop timing chain tensioner wear, causing rough idle and potential catastrophic failure. We address this by installing the updated timing chain kit LR096682 with <0.05mm precision alignment. Since 2009, we've completed 65+ rebuilds with this solution, and none have returned for timing-related issues - a testament to our quality control at Unit A5 Windsor Road.
