What have you done to your Tacoma today? 1st Gen Edition

Ideally, yes, imo. I know a bunch of folk who have welded what they could reach and have been fine, though. I'm planning on welding the back-side of mine when I have the opportunity; fwiw.

 

I welded mine without.

When I did eventually pull the engine, I decided they were plenty well welded. I added a few little beads on the back, but they probably weren't needed.

 

Perfect, did you do both hoses?

 

Because when you don't do your own work, like @CHMM is in the position of, it's usually cheaper to pay a shop to just install new ones rather than the time and hassle of them burning out the rubber bushings and installing the Whiteline ones. At least that's my knowledge from calling around a few shops in the Colorado area since I'm in the position of replacing my bushings.

 

What Brett said. In my opinion it's what makes them the best affordable UCA for our trucks.

If you have a heat gun and the factory bottle jack there should be no need to burn them out.

 

Had an evap code for a while. With emissions coming up I took it to a buddy that works at the dealer and checked the system, turned out to be the roll over valve was cracked. $76 dollars and 20 minutes later. Trucks fixed. Don't have any pics tho.

 

That’s correct. It’s cheaper to just put on new ones is what I was told from the shops around. Unfortunately I don’t have the time to do my own work. I can’t balance my workload for the last 5 years. It’s been 7 days a week non-stop and I can’t find good help right now.

 

X2
Lol,
I know the feeling

 

I had plenty of coil to do both, but I only did the lower. (comes in 4 ft lengths)

I'm running a silicone upper hose, which is more rigid than the rubber.

 

I guess I get that.

But man, I'd go nukin futz if I wasn't able to work on my own truck. And I'd probably also be bankrupt and divorced.

 

More time to work on the truck.

 

Glass half full kinda guy

 

She doesn't really take time away from working on the truck tho...

And she likes goin places in the truck...

I'd kinda like to keep her around

 

Good call. I'm working on finding one of my own like that.

 

They are like gold ma brotha... I know... I had to burn the a 1st wife to find the best wife.

 

Dang 7 days a week?! Too each his own, but I've just never understood the live to work lifestyle. I'm all in for 5, but that's it.

That's the ticket right there!

I keeping telling my wife she's not an idiot for choosing me. Hopefully she never realizes I'm full of shit.

 

Yep, no amount of money is worth having no time to enjoy it.

 

Mmm not much better clearance from what I can tell. I have them and not sure I gained anything there. Certainly aren't going to crack though

 

I've got them also, love them - that 1" let me do this with a 315 and uncut fenders:

 

Installed a reman head from cylinderhead.com on my buddy's 98 3RZ. I helped him buy the truck back in the summer of 2000 and he was my best man, so helping a friend like that out and doing it right was important to me.

It all started this spring. He said the CEL was on and the truck was down on power and idling rough. He brought it over to me and I scanned the CEL. P0300 and a few other codes I didn't write down. I knew the P0300 could be a few different things but that it likely wasn't good. I did a compression check. Cylinders 3 and 4 were in spec 185ish but 1 and 2 were way low.



Did a leak down. Cyl. 1 and 2 were leaking badly out of the exhaust valves



Turns out he had the usual crack in his exhaust manifold and in 169k miles had never checked the valves. Everything pointed to burnt exhaust valves and seats. In doing research here and Yota Tech, all the above symptoms pointed to the head casting likely being cracked too. There are zero decent machine shops within a few hundred miles of our town and after talking (or not talking; one didn't return my calls) with the machine shops around here for a valve job and possible cast aluminum welding, I quickly came to the decision to order a remanufactured head. Because of the low cost, ease of returning the core and solid reputation, we ordered a head from cylinderhead.com

No turning back now!


With the head old off, I was expecting to see super-burnt valves and crack(s) in the casting but this one looked really good. I likely could have done a DIY valve lap but the new head had already shipped.

What do you pros think? The pic doesn't show that exhaust valves on 1 and 2 are not seating the same way they are in 3 and 4



While I was waiting for the new head to be delivered, I did some other maintenance. The intake plenum was FILTHY!


I cleaned and re-o-ringed the injectors, installed new belts, new fuel filter and cleaned the throttle body and IAC valve too.
