Beginning to sort out my recently purchased Daytona. Due to CT weather I haven’t actually driven it yet but have started it a few times. After running it for 30 minutes or so I noticed a small amount of engine oil under the car (see pic). I wiped it up but left a rag in the area of the leak. It only seems to leak when it is started. Any ideas Thanks Image Unavailable, Please Login Image Unavailable, Please Login
Scavenge hose, also called return hose is higher than the static oil level and only has oil when running. Oil supply hose on the other hand is below the oil level. It is actually under a vacuum when running and often will not leak when running and will leak when not. I have seen supply hoses with a very loose fitting not leak when its running.
Romano, oil leak/seepage in a LH drive Daytona is most likely coming from the oil reservoir/tank drain plug or the fittings of the lower oil hose, which feeds oil to engine. Either can leak/seep whether the engine is running or not. Laurence, both of the aforementioned are best to access from underneath the car, drain plug tightening quite easily if you just lay on the ground and look under the fender apron. The tightening of the hose fittings will require large wrenches (M32 & M36, IIRC) and might be best to do on a 2-post lift or the car elevated off the ground, like on jack stands. Addressing either may require draining the oil from the reservoir/tank. OTOH, if the leak/seepage is minor, it shouldn’t prevent you driving/enjoying the car.
Very helpful Only leaks if I run the engine Once wiped up there is no additional leakage Will put it on a lift in two weeks when we put the refinished alloys on the car I suspect it is the upper hose Hopefully just tightening Thanks Wonderful forum!!
thank you timo I only asked if the oil is dropping during starting or when the engine is running. I once had a mercedes that only was dropping a little oil when starting, so using the starter. as soon as the engine was running there was no leak anymore. problem was an oil hose what was leaking only when cold and with a little oil pressure, as soon as there have been more pressure it was dense. this took me some time to find out
13-14 quarts is PLENTY of oil for a Daytona. With the oil cooler in the bottom of the radiator, your biggest problem is too cool an oil temp. More oil just makes things worse.
Everybody has opinions about oil choices. For the Daytona (and other Ferraris of this and earlier eras) I would suggest staying with a conventional (dinosaur) oil in 20/50 wt with zinc additives. Both Valvoline VR1 and Castrol GTX Classic meet these criteria. Synthetics are great for modern cars, but I guarantee you WILL have oil leaks with a synthetic in an older Ferrari as they were not designed to use and seal with these oils. Just one person's opinion. I am sure many others will also have opinions.
I agree. My choice for all (hundreds of) 50+ year old vintage cars, both clients and my own, I've driven/serviced/used in past 40+ years has been conventional/"dinosaur" 20W-50, which in past 15-20 years has mainly been "Racing" VR1. While there might be other "opinions", so far with combined +/-500K driven miles between all of them, I haven't experienced any need to consider changing to something else.
Motor oil is no better or worse than Valvoline Racing Dwight mentioned but the gear oil is garbage. Id just save the money and trouble and get Valvoline. It pretty cheap at Walmart.
