Rocky was in the garage workshop this morning. He said “Yoooo I got an engine gremlin.” Ok it wasn’t the original Rocky but a Rocky hardcore fan. The engine needed servicing so we got right down to it and checked the engine over replacing a water pump. The engine is now back out on the road working like a dream.
Here is the vehicle at our garage workshop.

A recent engine job
Only recently did we carry out an engine service for a Mercedes owner. We performed a leak test to see if the engine had a faulty fuel injector, because we have the equipment needed to diagnose this fault we were able to establish the fault and replace the fuel injector. Here are photos of the equipment and Mercedes dealer level tool we invested £25,000 in.
