Your goal with the Tahoe.

  • I guess that I should also explain why I had to go through the valve adjustment again. The problem is that lifters as old as these tend to leak down which throws the adjustment way off. To compensate,

  • VICTORY! The Tahoe is back! Runs like a new truck now. So, the funny part is that I had already fixed it and didn't know it. We found that there is a TON of resistance in the pickup coil in the ori

Do a youtube sarch for Flaco's truck, Texas mile...sarcastic, yes I know you will never go this fast in the Tahoe...but cool!

...and Arkus is the one dog on the planet strong enough to hang his head out the window at two hundred miles an hour...

anyway, done with the sarcasm, keep us posted Camino.

Despite my misgivings, I'll be taking a run at repairing the existing engine rather than replacing it. It's my only viable option at the moment.

Not looking forward to this one.

  • Author

Oh, I'm sure I'll manage it - but what a drag of a job.

That, and all of the miles on the engine, has me not so thrilled at the prospect of so much work.

I'd much rather be swapping-in a crate engine.

In that case, I'm in trouble. It always makes me grumpy to take a less preferred course.

I hear you...but there is always light somewhere.

Ran into trouble with a repair at work today, needed an expensive part, figured the customer would be unhappy....but they were not. Someone tried to break into my work truck while I was running the service call...but they didn't get in, thank you GM!

So two things I could have gotten frustrated and morose about....however....at the age of 46...I am slowly learning to be optomistic.

It is an uphill battle./..

Actually CSPEC's post here on C and g helped me realize how negative I got sometimes....I'm trying to make a real change...

Good luck on the truck once again, sir!

Yep...I kinda realized that myself. Being more positive.....

Ordered the parts to do everything today.

Parts were cheap, but the labor will be long.

One Tahoe marathon coming up.

I actually like the cold when I do wood working in the garage...usually a couple of 500 watt lamps will bring the temp from the twenties to the forties...and it's cold enough my wife and children leave me alone.

  • Author

I don't mind the cold to a point, but the barn is huge and very hard to get any heat into from my 2 kerosene heaters and 2 electric space heaters.

Should be fine as long as I get done over the next few weeks.

Picked up the parts this afternoon - now for the fun part.

Try to "tent" the Tahoe with tarps to keep the heat in. And keep positive NO negativity when it comes to engine work OK :smilewide:

Sixty Seven, I think that he needs to know it's okay to cuss it once in awhile....but yeah...no negativity.

Hell I cuss constantly while wrenching it keeps evil spirits away :smilewide:

  • Author

A certain amount of cussing is always required when doing automotive repairs - otherwise it won't work.

I cuss nonstop working on most cars. It blows off steam.

When things get real bad, like a bolt snapping off, I cuss so fast, the words overlap and get munged. New words, more vile than ever are created... then tools get thrown.

  • Author

I still don't have the warm fuzzies about putting this much work into the old engine - but I'll guess I'll tear into it tomorrow.

  • Author

Well, I've started. Not too much to report yet, except that there was a distressingly low amount of coolant in the system. And what was there was nasty, which should not be the case. Just a few months back, I replaced the coolant line to the manifold, the thermostat, and the water pump. The coolant was new at that time. The radiator was replaced about a year ago, so any issue are within the engine itself.

Here's hoping that it is the intake gaskets rather than the head gaskets.

  • Author

I'll be getting a look at the timing chain in about an hour - time to start getting some answers.

  • Author

Well, the timing chain is defintely full of slack - should have that replaced tonight.

But the big question is the intake gasket/head gasket thing. I know that the intake gaskets are bad, what I don't know yet is if they are responsible for my coolant leak. If not, I'll be diving much deeper than I wanted to into this engine.

I should know tonight or tomorrow.

  • Author

New timing chain and gears are in, cover is back on with new gaskets, and the balancer is re-installed. Tomorrow I'll re-install the lower pulley and the water pump, and remove the intake manifold.

The new timing chain is very tight, showing me just how worn the old timing set was. Hopefully, that cures the missing and popping through the intake and exhaust - now to solve the coolant issue.

I'll post some pics tomorrow.

Pics so far:

These show the progress, but not all of the work removing stuff and cleaning parts!

Now to feed the dogs and myself, and then get that intake off.

  • Author

Intake is off, and it isn't too pretty under there. But, the evidence is inconclusive as far as the head gaskets go. The debate now is do I clean it all up and slap it back together, or do I dive in deeper and do the head gaskets?

I'm sleeping on this one.

If you're like most of us, you're going to get really pissed if you don't do the head gaskets and they end up being the problem anyway.

You've got the top end halfway apart already, I'd just unbolt the heads and do it at this point regardless of whether or not it's the issue. If they haven't gone yet, they're probably going to go eventually at this mileage.

  • Author

Thanks JB, will do.

I have a line on some low-mileage heads that might make it all worthwhile. Stay tuned, I will post more pics as I go.

Agree with compression test and doing the head gaskets!

  • Author

I'm going to have to proceed on faith and do the compression test after the fact (if at all). Should have done it early on, before the trouble started.

Bob, amazing work. Keep bringing the good stuff.

  • Author

Thanks Zo6.

The snow interrupted this project and now there is another delay. I have to borrow the special puller to remove the power steering pulley (again) because you can't remove the brackets from the driver's side head without taking the pulley off first. Really annoying since I just did that to replace the power steering pump. I could pull the passenger side head, but then I'd be dead in the water until I get the special puller.

Umm Camino. In these pictures, the bolts on the Cam gear are not in the same position, yet the timing tooth on the crank gear is.....

Not to worry, The shift in position happened when tightening the bolts. The timing marks are properly lined up. Interestingly, the position of the marks when the #1 cylinder is at TDC are not adjacent. However, they are in line, and when rotated 180 degrees (on the cam gear) they are adjacent.

Believe me, I checked this quite carefully.

Glad I wasn't the only one to notice that. LOL.

  • Author

I cleaned-up the intake last night (took hours and isn't perfect yet), will go to borrow the puller today and decide what to do about the heads. Head gaskets are waiting for me at Napa.

  • Author

I'm a bit frustrated trying to get a handle on machine shop pricing to have my heads done. The local shop I was always familiar with has closed, and there are not many others anywhere nearby.

At any rate, time to head out to the barn and see if I can get something accomplished tonight.

Not feeling so hot, so it may be a short session.

I am feeling sick also...thankfully I have a scheduled day off of work tomorrow for a doctors appointment...

LOTS of automotive stuff around here has closed, including car lots, machine shops, high performance fabricators, etc.
