howdy
my dad just gave me his 92 truck
(he drives like a teenager so its pretty beat, but free....)

it has classic blown head gasket symptoms
(overheating and water in the oil)
the timing chain has long since worn out it's guides and is rattling/rubbing on who knows what

so l'm fixin to open it up to do those thigns

been reading up
tons of great threads on here
(so many it's a little confusing)

wondering what else l should do/look for while l'm in there
(injectors etc ?)

thanks

(l have more experience with diesels and this is my first toyota)

 

with hg and t-chain, all your gaskets will be replaced when you put it back together. thats a good thing.

do the injectors. if your motor is like mine was, it will be necessary as the little pintle caps on the ends were hard as glass with less strength. they broke when i pulled them. sent mine to 22reperformance.com and they sent me a b-e-a-utiful set back.

if you got the dough, might as well replace and adjust the tps while the intake is off, toyota t-stat too in case your bolts break as mine did. easier to drill/tap on a bench. remove/clean/test temp senders too.

you prolly wont like it but while your wiring harness is exposed, i recomend striping it of insulation and re-wrapping. get gooooooood tape. like the best tape. the one with the highest tensile/temp ratings. my bad insulation was allowing a grounding, causing a problem that literaly took YEARS to figure out.

since your dropping the pan, plasti-gauge your main and rod bearings.

thats all i can think of that i've had to do or wish i would do that requires major disassembly since my t-chain/head gasket.

and oh, dont forget new oil and water pumps. searching online will show great prices on oem pumps. im still rockin the original oil pump (i know i know), but while it was torn down my water-pump went bad and pissed my the coolant out the weep-hole when i was prepping for my first startup. i dont wish that pain on anybody. wrenches were thrown, and my tuck was subjected to some unnecessary dents from a 145lb young man in a deep, dark, very unhappy place. you dont want that. you dont want that

 

I say full rebuild it- bearings, rings and all.
Why you ask?
Because you said:

1) to me, something beaten up by a teenager raises flags
2) overeheating, rattling timing chain, water in the oil and worn guides
3) Its your first toyota.

 

4wd4fun makes a good point. if you got the dough, do everything you can. that way its done, you know its done, you know how you did it, and if you f$$$$d it up you can do it again twice as fast lol.

take my intake manifold for example

 

Before you start on a full-blown rebuild, you might want to look at Craigslist. If you can buy a Toyota that, for instance, just needs a new timing belt (6 cyl), it may be a lot cheaper than rebuilding one that has been ridden hard and put away wet.

Not as much fun, but if you're down to the point of replacing the insulation on wires (??!), who knows how much further you need to go just to get it driveable.

Just one man's opinion.

 

mybe my truck was just special, but yea, not the actual wire insulation just the plastic and lots of tape that holds/insulates it together. there are the injector splices and a couple others by the intake manifold, and riding on the pass. fender. if i was smarter, i would have tracked it down a few years ago when i learned that my truck didn't like to get wet. at all. ever.

prolly due to the coolant leak that has exhisted on that side of the block that has leaked for-ev-er. fixed now though.

 

whether or not it is worth it
is a good question

dont have the money for full rebuild

but l do want the truck to last long enough to be worth the effort/money l put in

the pumps seem like l should do them
especially if you have to open it up to get at them (is that the case)

time is also an issue
l dont have a vehicle so l want this thing back on the road asap

thanks for the replies
time for more research

I should be clearer. If it's a truck you know, and like, then it is worth putting money and time into it. Why else would so many folks on this list do a head-gasket job on a 23-year old truck? Then when you start on the head-gasket job, you're not as likely to have the transmission fall out 2 weeks later.

If you start with a truck that has a lot of visible problems and otherwise is unknown, maybe you're better off with another unknown truck that has fewer problems from the get-go.

Which is worse, a real beater from Dad, or a "good lookin" truck off Craigslist? THAT is the question ...

 

that is the question

gonna go take a good look at the truck next week and decide l suppose

thanks again

Did you ever say which motor?

22RE rebuild
3.0 swap to 3.4

3.0 is polishing a turd to take a dump again

:wabbit2:
