Buying 02 7.3l, tell me if I should back out

UnrepentantSinner · Jan 20, 2013

A guy has a 2002 CCLB, 6spd, dually for sale for $4k firm with 340k on the clock. Looks good inside and out, recent tranny and AC. Says it needs new injectors because of low compression, will start and idle, but won't drive. Is this an injector issue that I can correct easily or something bigger I don't want to touch?

so it has low compression, but injectors will fix it?

lol... walk away

UnrepentantSinner · Jan 20, 2013

I guess idles rough too, don't mind going through injectors, reasonably confident I could do that myself, bigger issues not too sure.

Get it warm and do a compression test. If you can't do that, walk away.

pull oil cap and see if it is pulsing pressure out, should be a lil smoke but no puffing, if it starts out in the cold with no block heater then you can rule out compression

Cold is relative, and following that advice is dicey when there is thousands on the line. If you cant warm it up and do a compression test on it then you can't KNOW what you have. And knowing is the difference in feeling comfortable paying an asking price and walking away from a bad deal.

New injectors will not solve a low compression issue.

Talk him down to 3 , get a junk yard motor for a thousand bucks and swap em.

He said his mechanic did a compression test, said injectors were the problem. I'm gonna try and talk him down some. He's in small town in the middle of no where, about 100 miles from me or I would haul it into ford and have them check it out. Worst case would be used motor from junk yard, what do those run?

Used engine price can vary greatly especially by area. Ive seen them go from $500(engine bay fire) to over $2000. Best to hit up car-part.com and look at your closest yard.

Its a good buy if the rest of the truck is that good. Plan on a motor and hope for less. How much work do you want?

WHS...low compression is no bueno...even the slight mention of that from the owner would have me walking away

If its not rusty yet and its in good shape buy it and swap the motor i bought a used complete motor ( oil pan- turbo) for 900 and the you got a spare everything or part out the old motor and make your money back for the new one

Is there a reason everyone wants to just throw a junkyard motor in it instead of just boring it and putting bigger pistons? Too much hassle?

UnrepentantSinner · Jan 20, 2013

What's it cost to rebuild a 7.3? Ballpark.

Stop.

Does it have low compression OR does it need new injectors OR both? Don't talk yourself into this. If you want a project and want to put another couple of grand into this then you can swap motors with a good compression junkyard one and swap injectors and sell a core motor for a little bit.

4k for a 340k mile dually.

7.3 trucks are everywhere. They aren't anything special don't let people fill you head with that. Save your $.

If you do decide to get it plan on keeping it since a 400k mile truck isn't the easiest to sell.

Depends if your keeping it stock or not (oh and Airfish is the guy i bought my motor from thanks again)

TyCorr · Jan 20, 2013

If he wont let you do a compression test, walk away. Or negotiate a motor swap into the price. There could be multiple issues with that mileage if maintenance wasnt good.

lincolnlocker · Jan 21, 2013

get it for 3k and rebuild it. or order a long block from riffraff for around 4500 or just a rebuild kit for around1200 with piston bowl machining. change all the wheel and differential bearings and have basically a new truck, that is if the body is mint.
