im a newb at all this mech stuff
i have a 91 22re
im pretty sure i have a blown head gasket
due to a water pump leak leading to an overheat
DOH

well
after draining my coolant for a water pump change (prolly the most mechanical thing ive done)
and having my coolant come out looking like this

im almost certain i have a blown head gasket
I also get white smoke on startup
with the FSM i found online, help from a pretty mechanically inclined friend, and of course the experts on here im pretty sure i could do it.
END CHAPTER 1.

CH 2
my question is
does anyone have any concerns with the lce engineering double row TC ??
i figured while i had the darn motor apart i should prolly change it (115k and no clue if it has been changed before?!)
i was gonna purchase it as well as the engnbldr gasket set
and also hopfully a camshaft
any comments or concerns i should know about before i head into this venture ??

Are your tchain guides broken? If so, make sure they didnt saw through your tcover. There is a coolant passage right behind where the drivers side guide is and it can chew through it and dump coolant into your eng

scuba

honestly i havent checked
ive only had the truck for about 4 months
i figure its the head gasket
should i just start with changing the chain and guides instead of the head gasket itself ??

toytech76

you can pull the valve cover and look down at the drivers tchain guide to see if its broken. If it is, you might want to find someone who can pressure test the cooling sys to check for leaks

just change the head gasket too. It will be much easier...but still a big pita though

toytech76

well the idea is to NOT just throw parts at something hoping you will fix a problem when you dont know exactly what it is. Thats the wrong way to go about things. If you ran a shop, you certainly wouldnt have much of a customer base doing that

scuba

ha
lol

if only exactly i knew what the valve cover was
is that the very top of the motor??

toytech76

yes. it has a plate with vac lines and switches on it. The V/C has 4 nuts with rubber grommets holding it down

scuba

so take it off
look at the timing chain guides ??
if all seems well what would step 2 in your mind be ??

toytech76

when pressure testing your cooling sys...pull your spark plugs out and check the cyls for coolant. If its present..pull the head

scuba

sorry for all the questions
but how would i pressure test ??
and your saying pull the spark plugs and if i see coolant in those holes i need to change my HG ?

toytech76

You need to get a cooling sys pressure tester. It fits on your radiator and you pump it up. You could also have a cracked/eroded head as well so, if there is coolant in there then you need to pull the head and have a machine shop inspect it

scuba

hmmm
intresting
honestly if thats the case
and this motor is more fudged then i think
i have a spare 22re from a wrecked 86 one ton
would there be much trouble swaping ??

scuba

dang
toytech got off
anyone else have any opinions ??

Back to the timing chain, I'd just replace it with the factory setup. Then I'd forget about it for a couple years and then change it again. Sure you could spend some cash on a more bullet proof 22RE but its not like they were unreliable from the start.

scuba

see thats the thing
i wouldnt have to spend cash on a new one
i have an 80k one in a wrecked 86
i was just wondering if this motor is more jacked then i thought
if it would be possible to swap that one in
and how hard it would be

Matt16

Pretty easy I would think. They're really simple motors. I think it wouldn't me much more work than removing the exhaust manifold, radiator, undoing the bellhousing and the motor mounts. Then disconnect and label the fuel and vacuum lines and some wires. You'd have to flesh it out a bit, but you get the idea. You luckily have a tonne of room to work in once the rad and exhaust manifold are out. It might be a bit tight on the passengers side, but doable.

My guess it would take you a weekend to unbolt everything then a weekend to drop in a new motor.

Anyone done this that would be able to confirm/ deny/ flesh out this plan?

mountaingoat

You could just put the other 22re in, sure - but what if your timing chain guides go on the new used motor in 20k miles? You'd feel a little dumb I bet.

I'd suggest going ahead and doing the head gasket and the timing chain/guides/etc. Once you've got the head off to do the gasket, then doing the timing components isn't that much more work or expense, and then you'll know you've got good parts in there.

If you'd just rather swap in the used motor with 80k on it, sure go ahead - but check the timing guides on new motor and replace them if needed BEFORE you swap out the motor, it's much easier that way. Then you'll know that the new motor you're swapping in is as good as it can be...

scuba

would there be any issues with the wiring harness or anything ??

scuba

anyone have any insight ??
