Engine Removal Needed to Fix Snapped Bolts

The Problem

This Porsche Macan came into our workshop with an oil leak that the owner had noticed getting progressively worse.

Oil leaks on modern engines can come from several different areas, so it’s important to properly investigate the source before replacing parts unnecessarily. In this case, the leak was leaving oil around the engine bay and creating that familiar burnt oil smell once the engine warmed up.

Our Diagnosis

After carrying out a full inspection, we traced the leak back to the rocker covers. Because the Macan uses a V6 engine configuration, it has two rocker covers; one on each bank of cylinders.

When we looked more closely, we discovered that two of the rocker cover bolts had snapped. This meant the rocker cover could no longer seal properly against the engine, allowing oil to escape. We managed to remove one broken bolt without too much trouble, but the second bolt was located on the near-side bank tight against the bulkhead, making access almost impossible with the engine in place.

The Fix

To carry out the repair properly, we had to remove the engine and gearbox assembly as a complete powertrain unit. Once removed, we could safely access and extract the damaged bolt without risking further damage to the engine.

We then fitted new rocker cover gaskets and replacement bolts, reassembled everything carefully, and checked the engine thoroughly for leaks.

After testing, the Porsche was running perfectly again and returned to the customer oil-tight and ready to go.

The Problem

This VW Up came to us with oil leaking from underneath the car. The owner had recently had the vehicle serviced at a main dealer, so it was understandably frustrating to discover an issue so soon afterwards. Oil leaks are never something to ignore, as they can quickly lead to engine damage if the oil level drops too low.

Our Diagnosis

We carried out a thorough inspection to find the source of the leak. After getting the car safely raised and checking underneath, we identified the problem: a crack in the sump, right around the area of the sump plug. This is a key point where oil is drained during servicing, and if overtightened or stressed, it can sometimes lead to damage like this.

The Fix

To properly resolve the issue, we fitted a brand new sump to ensure a solid, long-lasting repair. Once installed, we refilled the engine with fresh oil and checked everything over to confirm there were no further leaks. The car is now sealed, safe, and back on the road as it should be.

If you ever notice oil spots where you park or a warning light on your dashboard, it’s always best to get it checked sooner rather than later.
