I would like some advice on what constitutes 'bad' blowby. My 98 Suburban 6.5 Turbo has a constant flow of white smoke from the oil fill tube and obvious white smoke from the oil dip stick tube. I've done the CDR test and confirmed that there is negative vacuum at 1500 rpm so the CDR should be good.
About a week ago I just finished swapping out injectors, I had them rebuilt. About a month ago I replaced the water pump, flushed the radiator, after a radiator/heater line ruptured.
The rig is actually running fine, I haven't noticed any excessive oil consumption, loss of power, or coolant loss, although I'll be watching for these closer now. I'm hesistant to do a compression test because of the cost.
In one week, I'm planning on using this rig to haul about 10K to New Mexico....should I be worried. I'm not opposed to adding oil or patching things up along the way, I just don't want to be stuck in Podunk, UT for a week.
My question is: When should I be worried about blowby? How long, avg, will the engine run normally like this? Any other tests to narrow this down?
Thanks in advance, Chris
