just bought a new to me 79 jimmy 305, auto, np203 and here is the best, 14 bolt rear with 10.5 ring gear and dont know if the front is dana 60 or dana 44 8 lug(gonna look today after work.) got all this for 500 bucks my biggest question is what are some things i should do to get it running better. it will idle in park/netreal but when in drive it wants to die. i was planning on spark plugs & wires, change all fluids and possibly rebuild the carb. how well does seafoam work.

anyone know of any good places to scavange for parts??

 

 

thanks everyone

there should be as a lot of the stuff is shared with 73-80 GM trucks. When I had my 80 Blazer (that I also swapped in the 1 ton drivetrain) there were a lots of places that sold replacement parts for it.

First: Timing

Second: Fuel Filter

Third: Ignition system (plugs, wires, cap)

Forth: Carb (rebuild or replace)

You might also check for a plugged cat, if there's still one under there somewhere.

Vacuum leaks are a prime suspect if the problem is only when idling in gear, especially if it gets worse if you pump the brake (assuming vacuum booster . . . somebody may have put in hydroboost.)

YOu know how to tell the difference between the D44 and D60, right? 2 big differences are that the D44 has ball joints where the D60 does not. Also the D60 only uses 3 u-bolts to hold the leaf springs on. 2 of the studs on are in the top of the spring perch on the differential. Also, the everything about a D60 is much bigger than a D44.

      I'm suborn like that Ed. There's a plaque in my doctor office that says, "Don't quit, take a break." Works for allot of things.    Reality is, the wife loves her SUV and even given it's issues, she'd buy another if she found one with low enough miles. Then again she has me to maintain it.    Most of what ails this thing is GM shooting themselves in the foot and by extension the buyer. Besides a ridiculous breather system the cat warm up strategy, IMHO, is the dumbest thing I've ever seen an OEM do to a vehicle they warranty. On cold start it r-e-t-a-r-d-s the ignition to like -17* ATDC and dump fuel like kicking over a pail to force combustion in the CAT's for rapid warm up. This literally hoses the oil off cylinder walls and creates enough varnish precursors to stick rings in even well maintained engines. THEN if that wasn't bad enough they recommend using a wanting fluid specification at equally stupid interval.    Common to all GDI motors I'm aware of is this silly practice of driving the HPFP off the cam giving a leaking pump direct and unchecked access to the crankcase. And sir, eventually the ALL leak. Your job is to "catch it if you can". Yes, these are the same people that removed dipsticks from engines and transmissions in belief Joe Average wasn't capable of checking, reading and maintain his own vehicles fluids. Sadly  and in large they were correct. Most people these days can't tell a sparkplug from a fire plug.  Great ideas one and all.    Every move and every error calculated to defend themselves from the law and their own customers.

      Most online suppliers and Amazon. All have noted "not for use with Bose speakers".

      Very interesting thread. Definitely didn’t expect to see this kind of mileage out of that engine.

      Just did an injector/HPFP replacement on Pepper at 192,400 miles; close enough to 200K, RIGHT? (If 200K is considered life end and to me it isn't). But hey, to each his own.    Have never run a catch can on this vehicle. Back side of every valve looked like a new valve spray painted semigloss black. Port walls looked 'neat' (all a normal result of passive EGR via VVT) Zero build up even in AFM cylinders. Just color. It uses no measurable oil and never has.    At 155,000 I put her on E-85 and a borescope of the cylinders at plug change showed very clean pistons and valve faces. The replaced injector tips looked new. (It was the pump piston seal that was leaking). Oh well, have six good backups.    Still gets 28 mpg on gas (highway average) and over 20 (highway) on alky. UOA's look good and runs as good now as it did when I bought it. Better in fact.    What improvement would a Catch Can provide this motor?     And given all this I expect that IF I installed one I'd see some water/gas/oil vapor accumulation. Byproducts of normal combustion.   Having said that, IF my motor used an appreciable amount of oil I'd consider it a useful 'crutch' until I had the situation corrected OR if bore polished, until I junked it or rebuilt it to stave off repeated plug fouling.    I'm not telling you what I THINK. But what its DONE.

      Starting a new thread regarding mounting my 2014 OEM wheels to my 2026

      Love the look. I'm a SCSB lover myself.    Two items. 1.) A spacer changes scrub radius but this also changes when we use wheels of different offsets. A little isn't a big deal. 2.) Steel wheels, alloy wheels all have different thickness. Same effect on the stud and lug nut as a spacer. When hub centric the wheel isn't supported by the stud. It's supported by the hub. The stud just keeps it all together.
