HELP....Exhaust shooting white smoke when I punch it?, What is causing this white smoke?? Options

[jersey914]

I have a 74' 2.0 running Dual Dellorto DLRA 36 carbs. I just got my car back from my Porsche mechanic and I haven't had a chance to report back to him how it is running. I figured I would check with the experts until I can speak with him next week:

The car started great and runs great except that when I really punch it in 2nd or 3rd gear - at the moment of shifting, my wife (driving behind my car) says there is a puff of white smoke that is releasing from the exhaust. When I just resume normal driving or shifting without punching the accelerator before shifting, there is no exhaust plume. I am wondering what you guys think may be causing this?? Here is what was serviced on the car in the case that you think that the problem could be related to the servicing:

I had him remove the oil temp sending unit and replace sealing washer, housing o ring and housing gasket

He removed oil sump screen and cleaned - replaced the gaskets and sealing washer

Removed rocker assemblies and push rod tubes replaced and resealed all

Adjusted valves and replaced gaskets

As you can see, nothing was done to the carbs which is what I think you guys are going to say is probably the problem but because of all the oil that had leaked prior to sealing up the leaks I thought there's a long shot that there could be some correlation so i shared. The car runs great with no apparent back fires that I heard on this first 1/2 hour test drive.
