The Car Care Nut talks UR V8 blown head gaskets (3 Viewers)

[pvchaitanya]

Thanks to @prharper for sharing me couple of coolant strips. For some history, I replaced my coolant when I did valley plate leak 3 years ago. after that I developed the radiator crack leak. Its been like that for 1.5 years after putting 17,000 miles with that radiator leak, I was guessing that my coolant may have degraded due to that leak and exposure to air etc. But the test shows that the coolant is as good as new since the 3 years.
Looks like overheating or overdue coolant may be leading to this than having constant exposure of coolant via valley plate or radiator crack.

His recommendation to replace a "warped" block that was entirely within spec tells me everything I need to know.

Getting back on the coolant subject. My 2008 4Runner has had the original coolant until 290k miles when the radiator started leaking.

right, so what do you do? Tear the thing down, charge the customer for that, then pull the engine and replace? Of course, he is a Toyota OEM or nothing guy, but there are many engines out there, and newly manufactured units for well under 20k.

I wonder if there is an LS swap kit for Toyota?

So, where are the many available 200 engines ?

XAT 3UR FULLY BUILT Engine! Heads and Short block ASSEMBLED 800+ HP Long Block

Why isn't everyone running a 3UR?! After tearing one down and analyzing the engine top to bottom, we've really come to appreciate the level of engineering that has gone into these engines. It's no wonder they were made for over 15 years! We feel they're extremely underrated, and they also...

Did you own from new? Any head gasket or water pump issue(s)?

Guys, I jumped on the “band wagon” and did, my coolant today.

Here is a test strip picture. What seems to be added for me is that new coolant out of the bottle was close to natural pH and the one drained was closer to Alkaline first and last strips are control and didn’t dry yet, after they dried the looked like the ones in the middle. Tested two different bottles and in the middle of coolant drain and in the end. LX570 manufactured on 11/2016 currently at 74K Miles all the time in Florida (hot and humid).

I respect Ahmed (TCCN) and enjoy his videos, but I agree with other people here, I don't think 3UR-FE have more HG issues then any other engine. IMHO potentially lack of coolant maintenance can attribute to that but not necessarily. I'd say mostly HG failure can be attributed to engine overheat.

Bought the strips and tested mine today. I bought used at 170k and am at 210 now with unknown flush but mine is testing barely off new.

 

[Sandroad]

If I just drained the radiator and added new, how much coolant would I need?

My interpretation of that comment is that he doesn't think much of the Nut's advice, although it's left unclear.

I looked very hard at this when trying to decide what to do with my LC with a blown engine. But cost escalated very very quickly. Over $30k for a non-OEM engine. And no plans to make the horsepower they build these for. Even their stock option was crazy money.

Bought it with 100k in 2012. Still has original water pump. No head gasket issues as of yet.

Does any 3UR engine match LX570 like tundra iforce or lc200? or , are there minor timing differences?

Not really, I am not for or against the guy. I think he knows what he is talking about, more than most. But he does have some conflicting information, especially when it comes to the specifics.

If the block is within specs, it is within specs. In the video in question, the block and heads are within specs, case closed. But for him, it is not.

Someone with the experience he has, should not be having these conversations after the fact. He should know all the ins and outs, and have explained every option before the work began.

In his video, he speaks of "well now I am going to have a conversation with the customer". There should be no conversation. There should already be a planned course of action based on the budget of the customer.

Further he says in summary " well it is within spec, but i am not going to warranty the work." This would be problematic for me. If it is in spec, by the automotive godly like engineers at Toyota, who is he to question them?

He touts Toyota quality over all others, but yet has no faith in the specs and the engineering behind the parts and procedures?

That is my perspective. What is yours, since you wanted to know mine?

I think he has a valid concern about the head gasket blowing again and a conversation with the customer is in order. If it were my rig with those specs I'd say go ahead and do the job, I will except no warranty. It's good to have options and this would be mine, rather than replacing the engine.
Or maybe have it towed to a Toyota dealership where the job would be warrantied? I'm not a prospective 200 owner, just found this thread and thought it was interesting.

I saw that searching for crate motors after a recent mudder had issues sourcing an engine and had a thread on it.

My thoughts on a JEG’S crate motor… just because you can doesn’t mean you should.

Ford or Chevy… possibly. But those are in abundance and easily sourced for most applications.

I’m still waiting on a LS swap 200. After watching I Do Cars do the 80 series I’m sure it’s a matter of time given the expense of the Toyota blocks and heads.

If the heads don’t need machining, I agree. Machine the heads and going with a thicker head gasket… I’m not so sure I’d be so inclined.
