I was diagnosing a no start condition and when I put everything back together I didn’t seat one of the plug wires fully so one cylinder was either getting weak spark or no spark. The engine was not run for long, just enough to get it up to temperature. Should I consider the oil ruined and change...

The winters in Alabama are not terrible cold but it often gets into the 20s, and once or twice a year, drops into the teens or single digits. Are higher wear metals typically seen on oil analysis reports in the winter months? It seems like starting an ice cold soaked engine would lead to more...

I watch a few YouTube videos of people doing cold starts in extreme cold. I noticed something that’s very common is that the engine makes it very loud whining sound for a few moments after the start up. What is causing this? Here is an example:

My Ferrari Testarossa has large oil coolers with no thermostat. This is how hot my oil gets after driving 40+ miles at speeds between 80 and 110 mph on a 90F day. I’ve never seen the temp go higher than this. I’m told, by Ferrari techs, this is normal for a Testarossa. During the winter the...

I have a 1988 Ferrari Testarossa and a 1985 Ferrari Mondial. Both cars have flat tappet engines. I’ve been using Mobil 1 15w50 in both cars (factory recommendation is a 10w50 oil). I always figured 15w50 would be a very stout oil but I ran across a thread (linked below) that appears to show it...

I assume just horrible luck. He is making it right though, including paying for a transport to return it to his shop. You guys have convinced me, I’ll request that Lucus be left out.

My 88 Ferrari Testarossa just had it five year major service performed by one of the highest rated mechanics in the country. He uses Mobil 1 15w50 in these vehicles but also around a qt of lucus oil stabilizer. I was a little surprised by that because I’ve always heard that it actually does...

They don’t appear to be. I changed the pcv a couple months ago.

I actually was watching a video on this oil last night. However, I can’t find anywhere selling it. Is it still on the market? If so, would you happen to know how I might could get some?

Such as this? https://a.co/d/5ufd8jo

Thanks for the responses everyone. I really appreciate all the advice. Quick question, in addition to Valvoline restore and protect, would an Italian tune up be advised or unadvisable?

In my state yes, but in most states it’s not allowed. I actually have a letter from my Sheriff that I keep in the glove box in case any small town cops give me a hard time.

I’m not sure the true mileage of the engine as the car only has a 5 figure odometer but I do know it sit for years and years, being rarely driven, in a collectors garage before I obtained it. There is visible sludge that can be seen through the oil fill hole. I’m hoping the Valvoline Restore and...

If I can get it to stop smoking I probably won’t rebuild it. I’m quite satisfied with the power it produces, it’s definitely no slouch

I actually am going to try Valvoline Restore and Protect next week. I ordered some. I actually do drive this car quite a bit. I probably put over 500 miles on it this weekend alone.

That was actually my first thought. However, my mechanic said they determine that most of the loss was via the rings.

Thanks, I’ll look into it. I’m pretty sure the engine is just worn out, this car was a highway patrol cruiser in the 80s so it was probably beat on. Here are the leakdown results. Ironically, the car runs great and only seems to smoke when you accelerate from a stop. It blows out a puff, but...

What is Valvoline Restore and Protect, is it racing oil? I googled it and racing oil came up.

Its TBI

I have a 1984 Ford LTD former police car with the 5.0. There is a little puff of oil smoke upon acceleration and occasionally upon start up. I had a leak down and compression test done and discovered that the rings are worn and there is some blowby. I will be rebuilding this engine shortly. In...
