my trusty rusty chevy

Ok well My 01 silverado has a v6 the 4.3L its a good engine but most have problems with intake gaskets as does mine. So should I put new intake gaskets in and drive it til it goes cause I do have a big sludge problem. Should I spend money now and fix it or just save up money for a 5.3 engine and harness and hopefully my trans won't go out on me? Any help would be appreciated.

Why is it sludging? Toyota engines sludge iirc on wrong oil and not changing it often. Is that your problem?

It will be fine if it has been driven minimal miles. I assume you are talking coolant in the oil causing the goop.

 

[bigoilburner20]

no there is no coolant in the oil I have had the truck 40k miles and the engine sat since it was just put in at 121k i mean I change it every 3500 and the sludge is so bad when i draing the oil i have to use a screw driver to poke at it

Wow, havent seen that on any of our low mile GM motors. 4.3L's are tough engines, maybe try flushing with a 50/50 mix of diesel/oil and run it for a few minutes. After that give it a shot of auto rx.

As far as a replacement engine I'd look for a 6.0L and 4L80 from a 2wd 3/4 ton. Alot more power potential, same size block, tranny harness is the only difference, and that tranny is alot tougher.

so pretty much i should just keep it running and save up money for a 6.0 and a 4l80 I love that idea lol

With sludge that bad, are you sure you aren't getting dirt or other junk in the oil?
