Default I think I bought the dirtiest 6.0 in the country

I went to Vegas a week ago and I guess I wasn't done gambling


I took a risk and bought a 6.0 off of the local classified site in Utah. Supposedly it has 75k and was running(No proof of this). It used by contractor for the railroad to check the tracks.It was driven on dirt roads only. I paid 600 bucks for it complete except wiring harness and computer. It was supposed to be a 2003 but it is drive by cable so I'm betting it is a 2002.
I pulled the intake and there was nothing but mud on the valley cover. Like a quarter inch thick, but I pulled the valve cover and it looks good(No sludge and it is a nice light brown tint). I have not pulled the oil pan yet or done a compression test. Coolant was leaking out of the water pump and it looks like new coolant. They pulled the motor and scrapped the truck because it was wrecked.

What would LS1tech/Jesus do?

Break it down. Clean everything heavily. Rebuild with new bearings and rings and enjoy. :-)

Engine degreaser and laquer thinner will remove pretty much anything caked on and in the block. Even the worst carbon will come off from speaking in laquer thinner.

I would clean it off after sealing all the openings then do a compression test. If everything seems good I wouldn't touch it unless you wanted to cam it. Ls motors go 200-300k with no issues

I think the compression test is my next step.

Obviously you're going to want to investigate the health of the engine. I would do a leakdown/compression test and pull the pan to look for any obvious signs of damage.

I've bought some pretty grimy ones because they come from very rural areas...


"Don't judge a book by it's cover"...take it apart. Chances are, it'll be just fine...


These all were...

Here are the glamour shots



Whoops wrong one










The one issue is that I don't have a starter to do a compression test. I'm going to pick one up. Don't worry there are bolts in the engine stand now

I think they pressure washed it partially before they brought it to me.

Make sure you turn it over by hand before you use the starter. Just to make sure nothing is binding.

It turns without any issues with a wrench

Ugh

How should this look? It looks like they pressure washed the through intake. There is a really light surface rust at the front of the cam and on the timing chain.

Would you call the seller and as for money back or is this typical ?

No, not typical but if the bores are good, strip it down pressure wash or hot tank it and rebuilt with new bearings.

It looks like a typical work truck engine with extended drain intervals on the cheapest conventional oil they could find.

Oddly enough, I saw a dirtier 6.0 that looked like the oil was never changed. Sludge, sludge, and more sludge.

I pulled the pan today and no metal in the pickup or the pan. It looks like it may have a head gasket issue because the of the white triangle .


What do you guys think?

I'm putting an LQ9 back together that also has a questionable history.

oil pan/ oil looked good, and cylinders looked fine on mine. without starter/ power I think that's the best you can do.

I did all new gaskets, buttoned it up with some arp head bolts, and hopping for the best.

Are you planning to pull the heads before dropping it in?

I think I'm going to pull the heads next.. Especially with that white square in the oil pan, that looks fishy of head gasket issues.

I have seen a valley cover rotted thru from years of water in the knock sensor holes ...
That's a sweet engine lift plate ...
And truck must have had a bad cluster so they install an auxiliary oil psi guage??
