A friend has a Red top n14 he said the dipstick will blow out of the tube after he runs it down the road.Engine does not smoke and runs good he said. Also he said he checked the crankcase vent and it was open. He took it to a shop and they said he needed a rebuild.I was wondering if the air compressor could do this? Any other tests we could do? Any suggestions? I have not seen this truck I just work with him and am going on what he told me.Thanks,stump

Is it actually blowing out, or vibrating out? I have seen that on these engines. How many miles does he have on the engine? I would first suggest taking the vent system apart and make sure it isn't partially clogged.

Before we ever overhaul an engine for excessive blowby, we do a cylinder leakdown test. It's a bit of work, but it tells the tale....
