2010 Sierra first oil change

[consultIII]

did you spray any tbi cleaner etc. into the intake when you did the l.o.f. ?

what a/c filter did you use ?

ALL Full-Flow oil filters have a bypass valve in case filter becomes plugged.

Didn't think about the PCV system since it's been years since Ive had any problems with one. I'll check the hoses to see that everything is clear since that's exactly how it was acting. Also did not feel a need to spray any cleaner into the intake since it's so new. So far, it's been 24 hrs since the last smoking so I'll probably check the PVC system and let it ride until next oil change.

believe this engine has a fixed orfice not a pcv valve. have seen the fixed orfice freeze up and cause oil backup out the dipstick tube and back throught the air cleaner.

spec I found states 12-16psi bypass pressure ....ac pf48
this is not what most filters prior to 2007 have for bypass pressure when the filter has high pressures due to cold oil or filter media contamination ..

this PCV system has been modified but there have been issues with this...it does the same thing as the old style PCV ...only constructed differently....

I guess there are some who would feel the need to clean a brand new throttle body...! but you would have to spray a qt of cleaner into the intake to effect the oil level, that would not be very much a realistic answer..

You hadn't said anything about pressure in your comment I replied to, but even if the bypass valve does open (at any pressure) it simply means that the oil is not being filtered. It could not cause the condition described.

I was pointing out that these new oil filters are very different from the older gm engine filters,,, NOT that this design change had anything to do with the oil smoke on on cool down...re start...

I believe it had too much oil in it ....or some how the crankcase vent system is somehow screwed up..that caused this oil blue smoke issue on start up/....

comments about this new filter is basicly in my opinion a bad design to have bypass pressures of 12-16psi in a very tiny container..

good for a small fork truck engine but not a truck...

Now I understand what your saying & I totally agree with you. That's why I don't waste my money on National Brand Oils & Filters. I run only AMSOIL Oil & either AMSOIL or Donaldson Filters.

if you check it out amsoil does not have a recommended filter for these vehicles....!

wix has a #57060 and the K&N has a HP-1017...for the pf48...


my 2ooo 5.3L engine takes the wix # 51522....which used to be the ,,,,,a/c pf 59..which I did use until they [ac] stoped making oil filters..

Good to see that this has cleared up, for now at least. On a side note, you are changing your own oil on a brand new truck? Here in Canada until the power train warranty is up, you have to take it in somewhere that does the oil change for you. You can provide your own oil and filter, but they have to change it so that there is documentation that the oil change was done, otherwise if there is issues and no documentation that the oil changes have been done on a regular basis i.e. D.I.Y, they can void the warranty.

You are correct, AMSOIL does not have a Filter for the 2010 Silverado.....yet. But they will in the near future. When they become available, I'll pass this information on. In the meantime, AMSOIL also carries Wix & Mann brand filters.

If I lived in a dusty off road type area , I would install the amsoil bypass oil filtration with these new style filters...this would enable the synthetic oil to be filtered down to a few microns of particle size ...this would protect the engine from wear...most engines can tolerate 20 microns, but in a dusty environment this extra finer filteration filter appears to be a great solution...

Testing has shown that 90% of Engine (parts) wear occurs due to particles between 5-20 microns. (This is also true of Automatic Transmissions). Which is why all AMSOIL & Donaldson Filters filter down to 3 microns. They also have the heaviest construction in the industry. (Filter Housing, Baseplate, End-caps, Pressure Spring, etc.) Of course, the AMSOIL By-Pass Filtration System is the ULTIMATE in protection/efficiency filtering to less than 1 micron!

would agree, there is no need for a tbi clean at the first oil change.

Wasn't suggesting intake cleaner would effect oil level but any surplus that didn't go throught the engine could cause smoke on start-up. put too much through while its running and it will smoke like a locomotive.

Trying to offer new ideas as the oil overfill was a deadend...would take a gross oil overfill to smoke.

all the older vortec 4.3l smoke on every start-up due to leaking valve stem seals
