I just picked up a pristine 95 cobra with a Sportsman blocked 392 and a V2 s trim. Car has never seen rain and very well built. Noticed under boost I am getting white smoke out of the exhaust and a little up from the shifter area. Car runs great and coolant and oil look fine (no smoke any other time) thinking tune could be off a bit as car is breaking up a bit sometimes as well. The previous owner has been mixing racing gas with 93 could that cause the smoke under full throttle? I have a appointment with Pauls High Performance to retune the car. Car has been in a time bubble for 7 years and driven very little (maybe 800 miles a year). Second question is the car has a sumpted custom tank that was done very nicely with a weldon pump about 15 years ago...the tuner suggested that all the lines should be replaced due to age and corrosion concerns?? No leaks or gas oder that i have noticed does redoing this make sense at this point? Thanks for the input.

Oil is normally bluish but can def look white.

Coolant is white.

They have very distinct smells.

If you’re blowing coolant out under boost I’d expect to see some overheating/pressurization of the cooling system.

Coolant is white. If it is coolant you should definitely be able to smell it. I bet its a head gasket.

Used a combustion leak detector and test came out clean. Coolant and oil look good car is not overheating at all.

Likely a small coolant to piston head gasket leak. Keep an eye on the coolant level. If it starts dropping and you cant find an external leak, you will have your answer.
