DaHoooley, back from the dead as a 6.2 truck. The Phoenix rises

Duramax swap time!

:)

J/K, that's waaaay more work and money than I think you want to get into.

I'm thinking anyone who rebuilds these ol' girls should invest in an LPI kit and learn how to use it.......sure would save a lot of money up front.
 
Yess becoming a real P. I. T. A. for sure.

Got a couple possibilities that I can call in maybe.

Good buddy that has a local shop has a 6.2 thats in good shape with little to no ridge.

Local kid assembled it and did not tighten the rods properly and or used a wrong rod bearing andf spun a rod. Block is in good shape with good decks too.

Standard bore also.

The outfit that I got the Pan from has a stock of good Iron I believe and I will call him in the morning and see what he has stuck on the shelves.

I would love to cut for a new aftermarket block but, I just can't hack $1500.
Now if you add up the $$$$ I have spent on this Beotch to date, I could be cruising the streets with a fresh block.

Will see what can be had, Nice part is, that I can now go with either a 6.2 or a 6.5 since I have the correct pan.

Just really torques me to get all the way through this and then find it.

Better though than having a coolant puker later though.

Never seen a 6.2 with a cracked number #8 hole. The date on that block is 9-7-82 and its a 660 block.

The shop I use has had a few sleeves on these go sour and will not do any more on either 6.2 or 6.5 engines.

With my luck as poor as its been lately, I am getting goosy about any of it

"A Joke" :???:
A story with a humorous climax :hihi:

Yeah buddy, have not found a lot of humor around here lately.:eek:

Too many broken 6.2/6.5 parts to suit my mood :(

Missy
 
OK children, DONT FIGHT :nonod:

Hey I am a little irritated with this mess but, not down and out, and not all that discuraged either.

When your trying to build up stuff from used Iron, this sort of thing can happen.

The first build with the double cut deck was totally My fault for not being wise enough to think to check the block before I bought it.

Block was Guaranteed to be crack free, It was.

They did not make any mention or guarantee that the decks had/had not been cut before.

That engine ran sweet right up until I shut it off for the last time.

The inside of it was perfect. Had the Cometic gasket not failed (my choice to try it) this would have been a long life engine.

No real sense in getting all worked up and having your shorts in a knot.

I could have scrapped the thing when I first found the problem with the deck but, decided to try the Cometic gasket and let it rip.

The truck ran fine for a year. Now this is not anything to brag on for sure but the decision was made by me and I considered it a gamble at the time.

The info available made it look great and so it was done.

Now, this recent set back is just one of those things, $hit happens ya know.

I used to race Blown gas drag boats back in my younger days and we went through engines and parts like water out of a hose. Always breaking something.

Enough woulda, coulda, shoulda.

Time to get back to the task of resurecting the DaHooooley truck

UPDATE

Yesterday I called the folks that sold me the lovely 6.2 pan and had a chat about a good block maybe ???????? :???:

Got a call about 3 in the afternoon from the owner and he informed me that he had several 6.2 and 6.5 blocks back in the Bowels of the warehouse. :)

We discussed things and came to terms on a really nice 6.2 block that they had set aside about 10 years ago as a good builder.

I went over and looked at the stuff and checked out this block.
Its a 1990 6.2 with zero ridge in the bores. The decks look like the thing was assembled yesterday (almost) and the main bearings were still in the block and looked new.

Very low time on its clock me thinks.

Anyway, I got it for $275 after some serious whining :D

Going to get it on the stand here in a bit and get ready to wash it up.

Depending on what I find, I may not even install new cam bearings.

The critter is a tad mungy so it needs a good hot washing first.

I feel good about his one, but thats normal, I feel good about every GM diesel.

Later troops, need to go get the engine on the stand.

Missy
 
Mungy--= a condition of being covered in disgusting $hit, grease, dirt or other debris.

Any other description can be applied as needed.


Missy
 
I recognized the word, wonder if it's a PNW thing...

Good to hear you're back on track with another block. Everytime I click this thread I am afraid which way the rollercoaster is going... You have amazing patience Missy.
 
Latest update

Got the block on the stand and went after it. Got the soft plugs out, the cylinders lightly honed and the decks cleaned.

Still need to work it over well with the high pressure hot water and some serious cleaning soap/degreaser.

Decks look sweet as do the cylinders.

Still need to look over the main webs, but the preliminary peek looks OK.

The shop had the thing tagged as "GOOD 6.2, Save for a rebuilder"

Going to try to get some steaming done soon, just have to see how the time and ambition rolls out.

By late in the day, I really dont have much ambition left to do anything that requires manual labor.

Keep y'all posted

Missy
 
Might try soaking it with oven cleaner overnight before you hit it with the pressure wash. I've had good luck with that method.
 
The regular Gunk degreaser usually works well for me.

The biggy is, of course, the 2000 PSI 180F hot water from the Landa 4-2000 washer that really gets the job done.

The cleanup will be a snap once I get the hot water at the thing.

May try this morning, depending on whether I have deliveries to make with the big rig.

If I am off today, then I will try to get after this beast.

Really want to get it cleaned up so I can get intimate with it and not get filthy.

I have found that the high pressure washer actually does better than the parts washers that the shops have. Albeit it makes a great huge mess all over the driveway, but thats gravel anyway so not an issue.

Amazing what 2000 PSI directed into the nooks and crannies can do for things.


Later

UPDATE

Got off my arse this morning and rolled the little beast outside and went after it with the hot water.

Really swamped it out good in and out.

All done and ready to assemble now.

The little sucker looks great in all the usual places that need looking at.

I have carefully scrutinized the main webs, the cylinders and all the head bolt holes.

This sucker looks sweet.

All wrapped up and in a baggy at the present and ready for Missy here to start stuffing parts in it.

Tomorrow I will be on the road with the rig for most of the day so it will likely be this weekend before I can go for it.

With any luck maybe this one will be a winner all the way.


Missy
 
Nope, I am not going to mag this thing. The places that crack are visible to the naked EYE and all look great.
The main webs are the real iffy spot and these are all great. I had this sucker nice and hot with the hot washer and once dry I wiped the area off with Brakeklean.

No traces of oil seeping from any cracks, and it will if its warm. Been there done that.

The cylinders, decks and the other critical spots were wiped down with a little light lube to prevent rust after the wash all over.

I will be into this thing probably this weekend, so no worries.

Its amazing what 2000 PSI hot water will do to clean these suckers up.

Click to expand...

Pics would be nice if you get the time.

:)
 
Piicy's will be forthcoming.

Has not been much to look at up until now.

I will get some pix as soon as I start working on it again.

OH and for all those interested, and or holding their breath, IT WILL BE YELLOW again this time.

I love the "Mini CAT" look.

Still have yet to get a set of heads coming. I had the $$$ for them but other more pressing bills came along so the $$$ went there instead.

If all goes well I will get after the thing starting on Saturday morning and for sure get after it hot and heavy Sunday.

I dont generally set goals and such but, its not beyond possibilities that I could have the short block wrapped up by Sunday eavening.

This will depend on how ambitious I get and how well everything falls into place.

First thing will be to get the camshaft back in and then the crank and check the main clearances.

Going to use the bearings that came from the other engine.

All the same stuff so its going right back to work.

Once the crank is in the rest can go fairly quick.

BTW
One thing that I am changing is the oil pump.
I am installing a good standard 6.5 pump in place of the high volume squirt block pump.

The extremely high oil pressures made me a tad nervous.
80 PSI on a moderate weather cold start.
Can only imagine what a 20F or lower cold start would have been like.

The Yellow engine ran 55 PSI Hot down the road and idled at 35 PSI

The standard pump should be a better choice.

WE shall see.
