For the second time my newly rebuilt 302 had gas in the oil......
rofessionally machined 030 over with forged pistons.....
For the record it is not streetable yet, so no long drives, A break in start and the few start ups and warm up to back it out of the garage...
This is an 83 carbureted car, with a new summit carburetor.....
After the break in and maybe 2 start ups, I had a " helper" pump the brakes as I was bleeding them... To shorten this story he was pumping the gas pedal and I am sure he drained the primary carb bowl into the engine...... Did not start it but let it sit for a few days, letting it evaporate was my thought..
Smelled the dipstick and it was very gassy.. Changed the oil and filter, started and warmed it up maybe 2 more times
Had a noisy lifter so I removed the valve cover and the gas smell coming from the rocker arm/Head area was really strong....
Drained the oil ( overnite) and changed it and the filter.....
It ran and starts great, Idles fine with no smoke from the exhaust.... Fuel bowl levels are correct and I see no leaks....
I have read where the mechanical fuel pump ( its a brand new carter) can leak past the diaphragm into the crankcase.....
Been no reason to start it since the last oil change but I am a bit hesitant to start it ....... Next time I start it I would like to take it for a bit of a drive and warm everything up....
Some have said the engine has not had a chance to get and stay warm to burn this off, but it seems like there was a fair amount of fuel in it and I think the noisy lifter was due to the gassy oil..
Concern has also been that the " brake" helper washed the rings and created this when he pumped all of the raw gas into it, but I think this is a bit of a stretch, at least I hope so....
First SBF I have worked on and wondered if any of you " pros" have any comments.... thanks
