2000 Tahoe/White smoke only when temp is up to normal

[Saint John]

Thats a tuff call. Getting the heads decked, valves resealed, etc, new valves, springs, retainers, etc, can be expensive.

New heads, pull em out of the box, and set them on, and your off and running. And with new heads, you could get them customized for little extra money, honed, decked, etc.

At the end of the day, for me, it comes down to dollars and cents.

New heads can be had for refurbished - 300ish
New OEM style heads can be had for - 1000-1500
New performer style heads can be had for - 1000 to how much money you got?

With a stock lower end, unless you are going to drop in some new bearing, hone the liners, etc, I would stick to OEM or Refurb, or rebuild what you got.

I can get the new heads for 307 each. To rebuild and redo my originals, I'm hitting about 572 for it all. 42 more dollars and I got new heads

Case solved. New heads, but as was stated, I would hold off doing performance heads on a stock/old lower end.

 

[Saint John]

Yeah I agree 100% I dont really care for the performance part with this one. It has more than enough power to get wife and kids around

PNW VietVet I appreciate your help with this one....

Thanks, but remember, @TollKeeper remembered what my 68 year old brain did not think to say at the time, is the part about no performance heads on a stock old lower end.
I had a 1996 Tahoe that was a 2 door and I loved that thing and wish I still had it. I am really looking forward to following this thread. Might want to reach out to a mod to transfer to a Build Thread in the Under Construction section. You can go for days in that section just looking at all the pics from the rigs there.

This rig of yours is one that has been talked about several times here at the forum. We find them and post pics when we can. I wish you were closer so I could see yours. I would do as you said too, never get rid of it, EVER!

New heads it is then, don’t even need to think about that one. Following along!

PNW VietVet.... So I came across some bad news, and got some good news today. I decided to take a closer look at my block since it was stripped. There was a crack between cylinders 4 and 6. (Pics included) so... I ordered a brand new crate long block for her. As i said Never getting rid of it!

 

[OR VietVet]

Ok, well, you kind of wanted to go that way anyway and now you have a great excuse for the wife for why you HAD to order an engine.

Where did you order the engine from? What warranty with it? Stock block or some upgrades?

When you look back at your original heads and block pics, looks like the #4 and #6 cylinder piston tops are the cleanest ones.

Have you already made your list of what else will be done since you took it all apart? Hoses, belts, water pump....etc.

Gonna stick with conventional oil, if that is what you ran or are you running full synthetic?

 

[exp500]

You found the smokin hole!

 

[OR VietVet]

As big as that likely got when hot, I am amazed that you didn't have two really bad cylinders misfire.

 

[Saint John]

Ok I'm planning on going through my shop I work at. I have an elebrock 350 with a 4bolt main coming. It's a direct bolt fit for my other stuffalike my exhaust and it wont require any modifications. I liked the motor that was in it anyways so I really dont plan on going performance. I'll dress it up but thats about it.

I’m guessing the good news you got was that you can afford the new long block?

Yeah already orders it.

 

[PNWYukon]

Yeah already orders it.

What's the cost for the engine? Where does it come from?

Edlebrock and Im getting it through Summit, although I cant tell you how much due to how it was discounted through the company I work for.... Lets just say I'm under 17 for it. I can use my own intake instead of a carb so I dont have tonchange my computers. Which makes me really happy because I hate to change anything except the motor. I want to keep this truck as original as I can. I talke to my boss who thought it from, he had the transmission rebuild at around 200,000 so ive got 35 on it now. Putting a new motor in will definatly breathe new life into this girl.

Well, I finally am getting this build under way. I had some serious family issues pop up which put everything on back burner. Now, my new hear is ready to go into my baby....

 

[Saint John]

Before anybody asks, I had to help some family with some serious bills. So I had to go with a used motor for now. My step dad needed the money for some medical expenses, due to a recent diagnosis of cancer. So I gave them all the money for my engine. I scraped up some for a used engine with about 87,000 miles on her. I'll do a new one next year. But my family comes first...

Sorry to hear about your step dad but you are definitely a great dude to help him out with his medical expenses. You have your priorities right. Glad to hear you’re still moving forward, and all the best to you and your family.

 

[Saint John]

Thank you... Rocket Man. I'm just glad to be getting back to work on my truck though. PNW VietVet has helped me in my journey on this truck with diagnosis and stuff but she'll be coming home hopefully by the end of the week

Well old one finally gave in and came out. Tomorrow the good one goes in....
