Engine/Transmission (1998.5 - 2002) engine blow by?

[aharrow]

Just one quick question about my blow by I have an electric fan with a switch when the fan is off and i am stopped at a light it smokes pretty bad from out of the grill. Is it normal to have a lot of blow by or is something wrong any help will be great thanks Aaron

There is no way that thing should have blow by like that. I haven't seen any from my 99. The only 2 things that cross my mind is rings or some other way the crank case is getting pressurized (ie. head gasket?).

my 01. 5 has always done that, i cant see the smoke during the day but at night if headlights hit the smoke just right and if you have been idling for a while its visible

Same here as Jrollins only see it at night if the lighting is right

Mine changes depending on it's mood. I think my truck is female. Some days there will be no noticeable blowby, other days there seems to be alot. All my oil samples come back fine, so I'm not worried about it.



I wouldn't loose any sleep over it.

Pill Bottle

Most of this probably comes from the stupid "pill bottle" location. On your truck it is mounted on the front of the engine behind the fan. Any crankcase ventilation comes there. I relocated mine to behind the transmission within the first 100 miles after buying truck. It also is more prevalant after oil changes, etc. Side effect is that it cause nasty odors on co-pilots side which can result in considerable b**ching from co-pilot.

There is also a TSB from DC on this. Go to this link:

aharrow,



With no fan running and truck at a standstill, the blowby vapor is free to drift around the engine compartment. I'd be concerned about it fouling the intercooler, radiator and A/C condenser fins, among other things. As noted above, rerouting the blowby line clear of the engine compartment will solve that problem.

Thanks to everyone that took the time to answer my question looks like I will be moving the bottle this weekend Aaron
