1985 22r Head Gasket

Top to Bottom=
Victor reinz H.G.
Mystery existing H.G.
FelPro H.G.


I'm re-building my 85 22r P/U and bought the Vic R engine gasket kit. The VR. HG. had a factory defect.


The co. I got it from sent me a replacement Felpro gasket. It was identical to what was existing on my truck but the Vic R gasket (holes line up perfect) is of way better quality. The VR has a thin black bead of sealant, the FP does not. The VR has extra copper/brass (?) ring around the 2 middle head bolts, the other's do not. Voice over the phone told me that both VR and Felpro are the same as far as quality/longevity. I can put my own sealant on the felpro gasket, but what about the copper rings in the middle? Copper spray?

Also,
None of the Head Gaskets had a couple holes I think should be there. Here's the block. Note the holes next to the middle head bolt threads.


The head has matching holes.


and I know for a fact, this hole goes right to the thermostat housing and temp sending units.


Why were the holes drilled through on the block and head and not on any of the gaskets? Just to put a little extra pressure on the Gasket? Do I have the wrong Gasket (3x in a row)?

Well, as for the Head Gasket choice, I'm going oem from Toyota. It's like $30-40 so why skimp on a gasket that is so important. As for the Mystery holes, no clue why the head and block have matching coolant passage holes, but every Head gasket pic for the 22r I looked at blocks them off. WHY???

THIS!

A buddy of mine who builds 22RE's for a living uses ONLY OEM head gaskets for the very reason the OP posted. The Fel-pro garbage is low quality leaky junk. The Victor-Reinz is better, but nothing seems to be as good as OEM. For the minor price difference, why risk it?

I wish I had an answer for you but I don't. I just went OEM with my 22RE HG replacement recently. When you say adding your own sealant, what do you mean? I didn't come across anything in my research that indicated you needed to apply sealant to the HG - thought you wanted everything clean and dry before putting the new HG on?

You see that black bead on the gasket on top? That's "sealant" I'm referring to. That's the Victor Reinz HG. The bottom one still in the wrapper is the Felpro, and it has no bead of sealant (RTV-blk. maybe?)
I have also read, "install dry" on many posts so now I have a new question. Dry, sealant, sealant on both sides? Is the sealant considered "dry"? Is it even called sealant?

Think I'll buy the OEM, (whatever comes on it) and follow the manuals way.




Then, the bottom side of the gasket gets some sealant too. I guess just to 'hold' it in place while you mate the head and block. see 4.



Do you get what I'm asking about the "holes" tho?
It seems pretty important. More research i guess..

The sealant reference in the fsm is for the mating surface of the timing cover. I would go oem. I did in fact

I know what you're referring to on the holes....and don't know why they are like that. Oem!

Just saw we're neighbors. I commute to the bay every other week from Madera and stay in pleasanton with friends.
Pic was taken from Haynes and the "illustration" shows the timing cover installed, dude holding a tube of some mysterious sealant from the 80's, and it's aimed smack dab at the seam (t-cover & block) That's why it says, "Apply sealant to the two front corners of the block." Then, just to mess with us, the caption says to "Apply sealant to the cylinder head" It cant get to the block or t-cover if I do it that way,,, the head gasket is in the way! whatever, like I said, I'm getting OEM hg, finding out what that 'sealant' is and goin for it.
I think it's to 1. hold the gasket in place and 2. seal the top gap between t-cover, block, and head gasket. Maybe I'm hearing you wrong but it sounds like your saying it's for the t-cover to block OR timing cover to head gaskey only.

Cool, love pleasanton

Yeah I think the sealant is for timing cover to block/gasket/head union...altogether...to keep motor oil inside. The manual isn't very good about pointing it out, I agree.

Finally got the answer to the "hole" question.

Copied from web....
"Evening! The holes in the castings are there to remove fillers used during the casting process. Typically wires are embedded, then drawn out which breaks up the material, which is then flushed out. There is a secondary function, to allow for motion of the casting due to thermals and to draw off some added heat. Too much mass could cause cracks, there is a lot of heat directly under the deck when in operation.

The gasket then is used to block those off to force coolant flow in proper directions, this is to help it cool evenly. If it didn't, coolant would go round and round in a circle, the engine would overheat. Note some of the coolant holes are actually open but restricted, also." ~That was written by ENGNBLDR (Ted I think?)

Never severe ever add sealant to either of the mating surfaces. Also clean up the block and head to get all that crap out of there

So do ignore the Haynes instruction for installing the head? (pic^)
and ya, I haven't touched the block yet... The head gaskets are just sitting on the dirty block for pic purposes.

Not sure if this will help but here's my thread on my own HG install with photos and several folks chiming in:

Perfect! Thanks Philbert!
Here's the info I found on your thread.

" and to answer the question earlier about how/where to use FIPG on the top of the timing cover/Hg "

then a google search turned up this--

I also noticed you have a 87 4runner sr5, I am literally out the door in 30 minutes to pick one up I found on craigslist....
was gonna post pics and info in a new build thread soon... I'll definitely be visiting your threads in the near future. Thanks again.

I don't know if this will help but this is my stock headgasket.





those holes are there on the oem one but they are covered so from what the other guys said you should be fine.
