holy crap is it just me or do the 2000 up chevy trucks with 4.8-5.3-6.0 have intake gasket leaks like a mother fucker right now,ive had at least 3 for the last month every week ,more so now that is colder out,they come in with runs like crap when cold and cel is on ,you scan and look at fuel trim and its 25% long term.and codes are lean bank 1 and 2

there really is no point in this thread i was just curious

I think mine was something like that.. It was my O2 sensor though. Mine is an 04 Z71.

My work has a truck at the Chev dealer RIGHT NOW getting a intake gasket. 2003 6.0 ltr 2500 HD with 70,000 mi. Ours went on on a check engine and runs rough.

hahahaha see all you had to do was call me

[Got Diesel?]

you'll get a kick out of this, had it in 3 time with a check engine.

*First time -they said that nothing was wrong and just cleared the code (came back on pulling out of the dealer.

*Second time -told us that it needed plugs, wires, cap and rotor (yeah I hope you caught that)

*Third time -(this time) intake gasket

truck has a extended warranty on it (good thing)

I dont deal with Chevy's but in the last two weeks I have probably done half a dozen steering racks in caravans

but has anyone else seen alot of diesel leaks from injection pumps since they switched to the ultra-low sulfer diesel??

Not really. Is this a MB problem?

With the addition of the 2% Bio (it having higher lubricity rateing than petro diesel) it should alleviate the lubricity issues on the ULS diesel.

I wonder if the influx of pumps on those vehicle could have more to do with weather than ULS diesel. Number 1 Fuel that is mixed as a winter blends has a lower lubricating factor compared to #2.

It could also be said that the 2% Bio is causing it because of the caustic nature it has on some rubbers?


But IMO that would just be crying wolf.

yeah. only on the older cars though. and they all need $3-5,000 pumps.

Certain Mazda's are the same way, as soon as it gets cold outside the intakes start to leak like a son of a bitch.

[Max Power]

Our Chevy Van is in the shop for an intake leak. I guess they happen more frequently with a cold snap.

I have done 3 chevy pickups in the last month as well... seems to be commen... 3.1l 3100 3400 and 3800 all have the same problem I have done one of each in the last two weeks... this paycheck should look good I thinks...
