Ford Transit Custom Blown Head Gasket EXPOSED! Compression Test, Skimmed Head, Valve & Full Rebuild

🚐 Ford Transit Custom came in smoking, hard to start, low on power… and we had just 48 hours to save it. We suspected valve issues, but compression testing exposed a blown head gasket between cylinders 2 & 3. What followed was a full top-end rebuild: ✅ head skim, ✅ valve seat cut, ✅ valve lapping, ✅ compression retest — all done in-house and on a tight budget. This video shows it ALL — real diagnostics, stripped engines, and the exact tools, steps, and torque specs we used. 🧰 Job Summary: ✔️ Glow plug removal ✔️ Live compression testing ✔️ Head gasket failure between 2&3 ✔️ Cylinder head skim ✔️ Valve seat cut & lap ✔️ Vacuum test ✔️ New head gasket & bolts ✔️ Torque & angle-tightening procedure ✔️ Final compression results ✔️ Road-test & result 🔧 OGS Mechanics – We Specialise In: 🚗 Combustion Engines 🔥 🔌 EVs (Electric Vehicles) ♻️ Hybrids (HEVs & PHEVs) 🧠 ADAS & Advanced Diagnostics 📍 Visit Us: OGS Mechanics Units 9–14, Millers Yard Rear of 28 Long Lane London N3 2QG 📺 Watch Our Repairs in Action: 📌 Subscribe on YouTube → Weekly EV/Hybrid breakdowns, fixes & full diagnostics 📲 Follow the Behind-the-Scenes Garage Life: 🎵 TikTok:   / ogsmechanics   📸 Instagram:   / ogs_mechanics   📘 Facebook: https://www.facebook.com/share/15J54K... ⏱️ Timestamps: 00:00 – Visual signs: smoking, rough start, power loss 00:38 – Ford Transit history + customer deadline (48 hrs) 02:15 – Diagnostic scan & plan of attack 03:35 – Front-end removal for engine access 05:20 – Glow plug removal & compression prep 08:07 – What glow plugs really do in a diesel 09:38 – Cylinder 1 compression: perfect 10:56 – Cylinder 2 & 3 compression: major drop 13:14 – Head off!
