Toyota Land Cruiser Head Gasket Problems? WHAT IS GOING ON?!

We take a look at a 1999 Toyota Land Cruiser 100 Series with a Head Gasket Problem. This is definitely a surprise but it is a machine after all and age is taking it's toll a bit.
We discuss how the small head gasket leak was discovered, what caused it and a closer look at the awesome UZ series V8 engine from Toyota.

[@thegastronauts]

Same goes with me too.. Proud owner of 2002 LC inline 6. Got a problem with oil burning. Would love to see some info on 1fzfe oil burning issues. The cause and rectification procedures. Have more than 350000 KMS on the clock. Still drive like a charm both on and off road.

The fact something this complex has only just now after two decades had a material failure simply from age and not from its design is incredible.

no, it shouldn't fail from age, that's not acceptable at all on any low stressed NA v8 no matter it's 20 or 30 years old, not to mention this one is the one that's been taken care of. There are many many NA v8 out there that's 20, 30 years old don't have HG issue at all, there is one right in my head and it's not even come from japan

There is something so satisfying about listening to someone who is very knowledgeable about what they’re talking about. I don’t care what the video is titled on this channel. I never miss one. Plus that outgoing message always makes me smile. ❤

[@CalvinHikes]

Agreed. I have also learned that. I will listen to anyone who is a true expert talk about their craft. Somebody who really absolutely knows something can often communicate about it in a way that's quite satisfying.

[@djerniet350]

My 99 has 489k, and has taken me and my 2 boys and their family all over this country to different state parks for camping and amusement parks. Many beach excursions and has never left us stranded. Like he said this engine is so smooth and quiet sometimes it hard to tell if it's even running. Royal purple synthetic Oil changes every 3000 miles no matter what. One day one of my boys will get my truck and I'm sure it will have 400k more by that time.

[@adrianjay1972]

Thats exactly what my 06 GX470 does! Just turned 470k after yet another 3500 km round trip from BC to Alberta and back! Loaded up with 5 people and all the gear kids can sneak in! Lol Cheers to many more km of family exploring with these wonderful rigs! A 100 series is totally on my bucket list!

I would change starter, manifold and everything that will save me money in the future. This Land cruiser is niceee.

[@BW-kv9wj]

I have 1992 Toyota SR5 4X4 PU with 3.0 V6. The head gasket blew at 70,000. Toyota replaced for free due to the head gasket recall. At 150,000 they blew again. Again Toyota replaced for free. This time they said they installed the new and improved head gaskets and the honed my cylinders for free. It now has 500,000 miles and still running strong and smooth. I have an Amsoil bypass filter on it since new and only run Amsoil in the engine, diffs, trans and transfer case. I grease the 13 zirk fittings on the drive shaft religiously with Amsoil synthetic grease. This truck will never die.

Very subjective statement. I use my LC mostly to take my kid to and from school. Occasionally we might use it for a camping trip. We had a big storm once that flooded the roads around the school. When it was time to pick him up, my LC was one of a few vehicles that was able to get through the flooding. It was fun checking on the occupants of the stuck german SUVs that tried to make it through.

Those UZ V8s are the best engines made EVER.

[@nokomokwele5027]

Here in South Africa, these engines are transplanted into Mercedes 22 seater buses for longevity and reliability

[@YardpigTSI]

I'm super surprised you didn't just remove the engine to put on a stand. If it has that many leaks then for sure the oil pump o-ring and rear main housing o-ring is dried out and will be seeping oil shortly. Also could redo the oil cooler o-rings and might as well do the upper and lower oil pan gaskets. I couldn't imagine pulling the heads off on a lifted Cruiser with an ARB bumper, get that engine out so you can really go through it for your customer. Replace the dried out engine mounts and tranny mount too so that UZ runs smoother then new! Your best video yet! Thanks! A+++ #tccnautomotive #thecarcarenut

[@KesselRunLX]

I’ve done this job -twice- on my 99 lx470 at 217k with very similar symptoms -never overheated and the head gasket was externally leaking from what I figured to be rust. I did it twice because I didn’t machine the heads. Got lucky with a good machine shop -$180 to clean, check, and surface. I found to easier to pull the whole engine on attempt 2 +good time to reseal upper oil pan, rear main seal, and oil pump. Worth the work on such a great engine/vehicle. 235k now and oil analysis is beautiful and no leaks of any kind.

Thanks so much. I have a 2005 LX 470 with 211k miles. I am have a small reduction in antifreeze and just had the radiator replaced and they cannot find any leaks. I did send the oil in 2 changes ago for analysis but they found no anti freeze. I only lose about 2-4 ounces every month so I may have a similar problem. Next time I change the oil I will send it in for analysis. Not excited about a head gasket job but love the car. Thanks for the great info.

Valve adjusting shims! I’ve owned 5 Honda 6 cylinder CBX motorcycles. The shims are just under the diameter of the buckets, so changing them is simple, no need to remove the cams. Honda made a little two piece tool to facilitate removing/installing the shims. Some people claim the shims can be spit out. I never experienced that when observing the rpm limit of about 10,500/11,000 rpm. access to the valve gear is simple being a motorcycle engine. I enjoyed your video. Taking your time and doing everything correctly pays off.

[@jmaxim80]

You sir are 1000 percent right about the starter replacement on that engine. I've done 2 myself and the bolts to remove the starter will almost make you want to pull your hair clean out of your head. 😂😂

Is there a special tool to remove it? You have any tips? 01 LC owner here. Thanks

Ratchet wrenches with the hinges. Or a socket wrench with an articulating head would be my recommendation. But it's still not fun, but they will help.

Hello Car Care Nut, Love your videos. Not trying to be "that guy" but pointing out small error that can be confusing. I love you testing meathodology for flatness (head warpage) to a higher standard (0.05mm / 0.002"). When you whet to an even tighter tolerance it is 15/10,000ths or 1.5 thou.....you get it! Only posting for clarity. With more shops would do things the correct way vs. job-rate and blow it out the door!

[@MountainFisher]

I'm a retired engineer and worked in R&D and something I noticed about machinists/precision welders is how _careful_ they are about the process they are doing. Some are sloppy and some are not. My last company I worked at, if you were sloppy you were gone. They would hire straight out of machinist school and tell the newbie to ask questions and it is faster to do it right the first time than to do it again.
