In my first video on this F355, I detailed my preferred method for pre-service inspections, including checking for signs of failing valve guides. The Ferrari F355 is very susceptible to valve guide wear, especially in earlier models with bronze guides. Even later cars with sintered guides can suffer this issue, making a compression test essential before any major service begins. During this car’s compression test, I found a noticeable discrepancy between Bank 1 and Bank 2. I initially suspected incorrect camshaft timing, but that was NOT the case. In today’s video, I tear down the F355 engine in preparation for the timing belt replacement, removing ancillary belts, timing covers, and cam covers. Here’s a critical step: I don’t jump into the timing belt service immediately. Instead, I leave the belts tensioned to check camshaft timing on all four cams. This step revealed the timing was spot on—a rare find. So, what caused the compression issue? A leak-down test showed a 10% difference between Bank 1 and Bank 2, pointing to a worn valve job caused by worn valve guides. This unexpected finding meant pivoting to remove the cylinder heads and send them to my machinist. So instead of walking you through the cam timing procedure as planned, I will walk you through the steps required to remove the cylinder head from this 355 engine. It’s time to get to work! Whether you’re a Ferrari enthusiast, considering a pre-purchase inspection, or just curious about the level of detail required to maintain a classic like the F355, this video is a must-watch.

I imagine my early exposure to this culture ignited a spark of interest in cars, which remains my passion. 🎓 I am a proud Alumni of Wyoming Technical Institute ‪@WyoTechAutoMechanicSchool‬ where I studied Automotive Technology, Performance Engine Building & Street Rod Fabrication. In addition to "WyoTech," I graduated from the BMW Service Technician Education Program, more commonly known as BMW S.T.E.P. 🏎️ I spent nearly ten years working in various BMW dealerships as a Master Technician. After a move back home to the PNW, I found myself no longer servicing German-made machines but now working with Italians. I spent nearly another ten years as a Ferrari Master Technician & Shop Foreman at a local Ferrari dealership. 🏆 Ferrari selected me as one of 12 technicians worldwide to compete in the "Ferrari Testa Rossa Awards" for four years consecutively. Finishing in 3rd place in 2016, & in 2019 I was able to place in 1st, winning the competition & earning the title of the "Top Ferrari Technician in the World!" 🚀 As my time with Ferrari came to an end, a new career path awaited me…. Aerospace. I am currently working at Blue Origin, helping to build & develop the BE-3PM and BE-3U rocket engines. With my new career path, I needed an outlet for my automotive passion, thus the reason for this channel… #ferrari #ferrarif355 #f355 #exotic #ferrariservice #ferrarirepair #seattle
