YouTuber installed a twin turbo kit on his Lamborghini, but an oil smoke issue is preventing a proper dyno run.
While any Lamborghini will turn heads, there is just something magical about adding a set of big turbochargers to the Italian supercars. The host of the Tavarish YouTube channel recently took it upon himself to add a twin turbo setup to his Gallardo and he wants to get it on the dyno for tuning and testing, but an oil smoke issue is standing in the way.
Hunting an Oiling Issue
The video above begins with the host explaining that he has been working on his “cheap Lamborghini”, including adding an adjustable suspension setup and troubleshooting his twin turbo setup. His goal is to get the car on the dyno, where the shop can properly tune the boosted engine and see how much power it makes, but first he has to address an issue with the car.
In a short cut-a-way where the owner fires up the Gallardo, we can see blue-white smoke coming from the rear of the car. Anyone who has spent any time working on performance cars will recognize this as oil smoke, so before getting the car to the dyno – he has to find and fix the oiling issue.
Check the PCV System
The host begins by explaining how his dry dump oiling system works and how he does not run a conventional PCV system. On a car with a traditional PCV system, excessive crankcase pressure can lead to oil being sent into the intake at unusually high rates, but his Lamborghini doesn’t have a recirculating system, so there is no chance of this being the cause of the burnout oil. Just to make sure, he shows us the spotless intake tubes.
The Troublesome Turbocharger
Next, he looks around the rear end of the Gallardo, focusing on the oil lines running to and from his twin turbo setup. When he spots some oil on the garage floor below the driver’s side turbo, he has found the location of his problem. Upon further inspection, he finds that the oil is leaking around the seals and dripping off of the outer housing of the turbocharger. The inside of the housing is clean on both sides, so the host believes that there is excess oil pressure causing the leak.
While he doesn’t know for sure, he believes that a Y-fitting in the oil return line system is causing too much backpressure and as a result, the oil is leaking around the seals of the turbocharger. However, he doesn’t know for sure, so if anyone reading this has any input on how to fix his problem – he is clearly open to suggestions.
"Before I was old enough to walk, my dad was taking me to various types of racing events, from local drag racing to the Daytona 500," says Patrick Rall, a lifetime automotive expert, diehard Dodge fan, and respected auto journalist for over 10 years. "He owned a repair shop and had a variety of performance cars when I was young, but by the time I was 16, he was ready to build me my first drag car – a 1983 Dodge Mirada that ran low 12s. I spent 10 years traveling around the country, racing with my dad by my side. While we live in different areas of the country, my dad still drag races at 80 years old in the car that he built when I was 16 while I race other vehicles, including my 2017 Dodge Challenger SRT Hellcat and my 1972 Dodge Demon 340.
"Although I went to college for accounting, my time in my dad’s shop growing up allowed me the knowledge to spend time working as a mechanic before getting my accounting degree, at which point I worked in the office of a dealership group. While I was working in the accounting world, I continued racing and taking pictures of cars at the track. Over time, I began showing off those pictures online and that led to my writing.
"Ten years ago, I left the accounting world to become a full-time automotive writer and I am living proof that if you love what you do, you will never “work” a day in your life," adds Rall, who has clocked in time as an auto mechanic, longtime drag racer and now automotive journalist who contributes to nearly a dozen popular auto websites dedicated to fellow enthusiasts.
"I love covering the automotive industry and everything involved with the job. I was fortunate to turn my love of the automotive world into a hobby that led to an exciting career, with my past of working as a mechanic and as an accountant in the automotive world provides me with a unique perspective of the industry.
"My experience drag racing for more than 20 years coupled with a newfound interest in road racing over the past decade allows me to push performance cars to their limit, while my role as a horse stable manager gives me vast experience towing and hauling with all of the newest trucks on the market today.
