Idaho BS thread in the PNW

Ah, yeah. I was looking at putting an LCE header on mine, and it was gutless in the mountain highways with a load. But it would crawl up a wall. But then half of that is tranny.

 

I did that to mine did a cam and injectors and header intake mods all sorts of shit.. it would smoke the tires in first gear but on the freeway still was a pile.. got good mpgs and would walk up a wall in 4lo but no high speed stuff.. good motor if you dont mind the lack of power.

Point i was making is if you want that power swap in a bigger motor.. there is no replacement for displacement..

 

Yes. Dependable, yes (as long as the timing chain guides don't go south unnoticed), fast, no. Especially in a 4x4 Xtra cab...

 

get a 20R timming chain kit for it double roller and steel guids.. problem solved
EDIT: i you have to get the 20R oil pump drive or cut the 22R oil pump drive down..

 

I don'thave one anymore, but yeah, I remember inspecting the plastic guides every time I did the valves, and I researched the metal replacement guides just in case...

Yay interference engines...

 

no different then the 3.4 only it has a beefy belt.. seen a factory belt go 180K and not break the water pump on the other hand didnt fair so well.

 

I understood that the 3.4s are non-interference.

 

I think youre thinking of the 3.0V6 it was a non-interference engine.

 

Or the 4.0. I believe it is non interference.

Ok, let's settle this once and for all.... for the 1999 Toyota 3.4L engine, they are non-interference. this is from actual measurments of the valves at full open, Both the [COLOR=blue !important][COLOR=blue !important]intake[/COLOR] and exhaust extend 3.8mm beyond the mating surface of the head. The piston is cupped and is 4.6mm deep. that is a .8mm gap without adding the thickness of the head [COLOR=blue !important][COLOR=blue !important]gasket[/COLOR][/COLOR].

Where did I aquire this information, easy, I measured it myself.......

Maybe this is why there is confusion; valves extend below the bottom plane of the head surface, but the pistons are cupped.

 

the 3.4L is non interference..so are 7mgte, 1jz, and 2jz..wouldn't be surprised if most Toyota motors are.

 

Made me think of this Nova. haha
