‘Minivan-duty’ 2GR-FKS break-down vid

Minivan Duty requires the strongest of engines. Minivans live their lives heavily overloaded, and perpetually underserviced, and are crammed into engine compartments with inadequate cooling, while they suffer endless cold starts and stop-and-go traffic for their whole lives while still running on the factory oil fill after 7 years.

 

Yeah. I wish I had the space and skills to go down these rabbit holes.

I agree with you, at some point, the 2GR-FKS is going to be so plentiful, and readily available as a used engine, that I believe it will become a defacto platform for mods.

 

The Tacoma engine will be indeed. Hard to say about the car version of the engines (totally different block casting due to mounting differences) this engine in the FWD layout appears it will be a short lived engine vs the almost 15 years of 2gr-fe in cars

 

I think we are all aware of this channel now, but it you are not, it’s worth a look. Covers a lot of the same points.

Don't feel bad Rusty, by the time he started talking about the fuel system and poking around in there, I was thinking to myself that these things are disposable anymore. Let's hope they'll last 300k miles.
Great video, and yes this guy is sharp!

 

The irony is, of course, and I think we can all agree, that automobiles and trucks are more reliable, across the board, than ever. So whatever the complexities of these modern engines might be, they are far less prone to problems.

You hardly see a modern vehicle broken down at the side of the road with its hood up, like you used to. If you do it’s probably a German brand. Even Jeep seems to be making mostly decent vehicles.

 

I was shocked to learn the Cylinders had a "spray in sleeve" and can't really be bored.
Not that you could ever make any block last forever, but still a bummer to learn that.

 

Awesome Video. Thanks for sharing. Love these types of videos where they tear down an engine that you currently own. Well, similarly own. Quite complex and are technological wonders compared to the good old days. I remember when fuel injection became a common standard feature. Points and condensers moved to HEI. So much more reliable these days.

The only thing that concerns me with this engine is the plastic valve covers and plastic cooling system connectors. Not sure about those in the long haul.

 

Most vehicles on the side of the road way back then and now are there because of poor maintenance.

I feel the old vehicles by and large were plenty reliable -- but they required much more frequent maintenance to achieve that level of reliability. Breaker point adjustments, brake adjustments, valve adjustments, seasonal choke adjustments, etc. were a part of life with the old cars. And nobody was ever quoted $600 for a spark plug change either.

Modern ones will certainly run much longer without servicing, but those infrequent services sure do cost more. Back in "the old days" a little knowledge and a few tools from Sears was all a fella needed to keep a car running well. Miss those days...

 

Yeah it reminds me of years ago I was asking a coworker (gear head/race car dude) about freshening up a small block chevy engine and if rings and pistons could be replaced without a bore. His reply was it depends on the wear, he said some iron blocks could show 7 thousandths taper in as little as 50k miles. But he mentioned iron Toyota blocks with high nickel content could show hardly any at 200k miles. He spent a bunch of time in a automotive machine shop.

 

Engines have had plastic valve covers since the 1980's, I'm OK with that -- the plastic in the cooling system doesn't give me a tremendous feeling of security either.

 

Most engines have been like that for well over a decade now. I think the 4.0 may be too? But don’t quote me on that

 

I know that my Suzuki Hayabusa used a coating SCEM their name for it. Looks likes it's been around awhile.

 

I first heard of nikisil in the 1980’s when it was used in some 2-stroke dirt bike engines that could not be re-bored.

 

Well I don't build engines, so I didn't know that. It was cool to learn

 

The first gen NSK engine pretty cool too. It had ceramic impregnated liners for extended service life and to reduce internal friction. Not serviceable, but pretty cool technology for the late '80's, early '90's.


Edit :Well if I had just read @tacotoe 's post I would have seen that it is the same technology. I guess that was the first time I remembered reading about it.

 

There is a super small allowable tolerance Toyota doesn’t list. But Marc and some others have found you can take what’s literally next to nothing out to remove light Scoring and have no ill affects

 

that issue seems to be isolated to the tacomas. the FWD based ones i havent seen any failures yet.

a fair few tacos for sure though... and its a terrible job to deal with lol

 

The liners are not sprayed on, they are cast in iron sleeves.

 

This is correct. They are iron liners in the 2GR family, at least according to Wikipedia.
