lol...nevermind.
i'll just say putting the pistons in is easier if you use the tool correctly!:doh:

anyways, here is some 22re porn to tide you guys over...if anyone is still following this thread anyways.


first one is my makeshift paint booth drying area. second one is the block with newlyinstalled pistons and crank!!! ahh progress. beer thiry.

Head gasket question

i ordered my gasket kit complete from toyotapartszone.com
but it appears my head gasket is missing some holes for the water passage. my block has holes inbetween the cylinders. the head has them. but there is no holes in the head gasket for the water to pass from the head to the block.

the oval ones are there, but why not the round ones inbetween the cylinders? do i have the wrong gasket or a different version or something? i would rather have the holes if i can get them.

looks like toyota parts zone originall has **115-35040 as the head gasket part number.

but underneath it says replaced by **115-35060.
I wonder if that is this crappy gasket i have that is missing water passages.

 
Good question. I do know that Toyota uses hole size to control coolant flow rate so the size of hole if needed is important.
 
Bogo,
Yeah the photos in the link you mention look identical to the head gasket i have. Neither of them (mine or Napa one in the link) have the holes i am refering to for water passage. in my block and my head there are two additional circle water passage holes inbetween EACH cylinder.I wonder what is going on here. Is it possible that there was too much flow in the original design and toyota made this change?

although, i dont understand "too much" flow. is that possible??

Flow may have been uneven, and not in the right place so they made the changes. Also they may need the holes in the block and head for casting reasons, but not for water cooling. They also could be there to help make it lighter.
 
well, I called LC engineering. they said that their head gaskets that they use are of the same design as the one I have. but i did find a picture online of a head gasket that had the holes i am talking about. here is a link:
22re head issues.
its the two inner most circular holes between each cylinder.
so they did manufacture the head gasket with the added holes at one time. why they changed, I do not know.

How about the head you're getting from Ted? Does it have the same holes as the block?
 
ridgerunner,
yeah the head from ted is in the top picture above. it has those holes all down the head inbetween each cylinder. as does the block.

the only thing i can gather is that toyota cast the holes originally, then found later that the cylinders were not getting to the proper temp. so they blocked / orificed the remaining ones.
 
mini update

well,
since I am waiting on my new toyota rockers to get here, (along with some little bendy twisty water hoses that i would never find locally)

i went ahead and did some work on my timing cover. when i disassembled the engine i noticed there was some scarring where the oil pump gears ride on the machined front surface of the cover. hopefully, this was at least in part what was causing my low start up oil pressure.

anyways, rather than buy a new one, cause the backside has no chain wear at all, i decided i would machine the oil pump surface flat again. hopefully this will give me a nice seal there and my engine wont loose prime. additionally, it will clean up that bearing surface for the new oil pump.

I already examined what impact this will have on other components. the only thing that it will effect is the splined drive for the inner oil pump gear. but the splines are so long, that moving the oil pump gear down the splines a couple thousandths of an inch wont matter. and even if it did, i could just machine whatever i take off the front of the case off the back of the splined drive and it would be back to riding where it was anyway.
(if none of this is making sense, i will post some pictures tonight when i get home)

well, i went ahead and trued up the bridgeport last night. then fired it up with a fly cutter and got to cuttin'. turns out the front oil pump surface of the timing cover had about .0015" runout across the face from the factory. (i measured the unworn bolt hole areas outside the oil pump seal). So i took that much off to flatten it out and true it up with the rear mounting surface that bolts to the block. Then to get the scratches out, I ended taking off another .0015". so all in all .003". which is not bad.

I'll attach finished pics of what it looks like tonight when i get home.

Let's revive this a bit.
So I finally got my rockers in on tuesday.

Last night I completely cleaned and rebuilt the valve train. All new springs, adjusters, nuts, rockers, and LC engineering chromolly coated shafts.

Then I put the head on and torqued to 58 ft lbs with my new studs. Finally, I put my freshly painted up valve cover on there just to see what it would look like. couldn't resist. I think it looks great. What about you guys?

I still have to do something about my exhaust manifold. If you dont remember, its a little warped according to the FSM standard, but I held it up there and I think the gasket is indeed thick enough to take up the slack.

My only question is, what color should I paint it? I kind of am leaning towards the same VHT alulminum paint i did for the valve cover, timing cover, and water passage pipes for two reasons. One, it would match the egr tubing that goes over the manifold. and two I only have a little bit of the high temp semi gloss black left. If I want a couple good coats i would probably have to get another can. not a huge deal, but its more $$.
so what say you? more VHT aluminum color, or semi gloss black to match the block? it could provide a nice constrast?

Let's play...WTF is this for...

Will the first contestant please step up...

So in my complete engine rebuild kit from toyota stealership, there are a couple gaskets that I do not know what they are for. any takers. Mainly the thick rubber gasket. I know what you are thinking, its the thermostat gasket. but its not, I put that one in the pic for reference. its much thicker. and spongey:clap:

secondly, is this blue washer thingy. could that be the oil pan drain gasket?

lastly, there is a small paper gasket that looks like the pickup tube gasket, but the holes are smaller than the pickup tube gasket. and it has those weird tabs on the side.:meh:

Looks awesome.

Small blue washer is for the oil drain plug.

Split O-ring is for the thermostat.

Paper gasket is for the cold start injector.

Big thick gasket is for the oil fill cap (look underneath).
