planning on using 1 layer oem gasket, which layer should i use and can i re-use the old gasket? do i use same torque specs or higher?

- engine is JDM itr

Who has the lowest price for ARP head bolts on H-tech?

 

PM this guy name v4lu3s, thats his sn on HT, he hooked me up with my h22 head studs pretty damn cheap, i forget how much cuz that was over a yr ago, haah.

 

bump for more input.

 

come on, i know there's people out there that have used single layer head gasket.

 

that sounds like a blown HG waiting to happen, for-sho.

 

i've searched and there are serveral that says they had no problems but none have PM back to me.

 

I know people who had blowout problems running OEM 2 layer gaskets; do you seriously think a 1 layer gasket will perform as well? Think about it, the factory makes these 3 layer for a reason. Aftermarket companies make 2 layer gaskets, but they designed them to perform as such. Removing 2/3 of the stock gasket isn’t the best idea out there. Why don’t you just use a 2 layer and get some flat head valves? That will give you more of a CR increase then a 1 layer ghetto rigged HG.

 

I have used a single layer Honda gasket ( top layer ) on an all-motor project street car B-series motor at 86.75 mm bore. It worked great, no problems at all. Drove to and from work everyday until someone jacked his car while in Las Vegas. It worked exceptionally well though

 

never said it woudnt work. And a working HG is a working HG, nothing exceptional about it. Its either leaking or not, the point is that this increases the chance of a blowen gasket by quite a bit.

thanks for the input. is there a reason why you used the one of the outer layer instead of the middle layer? is the other layer made of softer metal so that it'll crush seal better vs the middle layer which is just a shim. what torque specs did you use, oem recomends 63 flb.

 

when modifying an OEM HG to be dual layer, you remove the middle layer.

 

i used 1 layer also (black ) haven't have a problem yet .. i have arp head studs
and tighten to 70ft lbs .or honda spec if using stock head bolts..it should be ok as long the head and block are straight.

 

i check the head and block last night with a straight edge and both are good. did you said you used one of the outer layer and did you used coper spray.

 

almost everyone i know uses the middle layer and torque to 75lbs with arp studs and NEVER had a blown headgasket yet.my race car is a 87mm b-series on a single middle layer torque to 80lbs and still have't blown a gasket.some people say use the bottom layer due to the fact that it has a fire ring but i just stick to what worked so far for me.

do you think it's a good idea to reuse the middle layer from the old head gasket? i have a new one but i don't want to take it apart if i don't have to. i was going to reuse the oem head bolts too, but i think i'm going to use ARP now so i can torque it more. thanks for the input guys.

 

you can re-use the old gasket,we re-use them all the time

 

when i use a 1 layer head gasket, i always use copper spray...no blow gaskets ever....

 

good to hear from people who have first hand experience with this setup and have good results. not a bunch of people who heard or read about it somewhere saying it's unreliable and not a good idea. you can blow a stock 3 layer gasket if you don't install it right, it all comes down to the quality of the work.

when you used copper spray, how much do you put on. do you concentrate more around the ring area or just spray it evenly?

I spray it evenly..a good couple of coats!

 

i never use copper spray,i use the indian ink

 

I wouldn't reuse the gasket, especially if your gonna be peeling layers off of it.

I would start off with a new gasket for sure, and use copper spray, just give it a thin coat all over.

I havent ever used a single gasket, but i am running a 2- layer gasket and i used copper spray no blowout problems.

 

can I also use one layer on a d-series engine?

 

i dont think a middle layer would do as good ajob, its not made to seal, i dont think. looks like makde for filler space to me. the outside ones look like they were made to seal tho.


yeah i would make sure SURE that the deck was flat, i believe this is the main cause of them blowing out. and if it is, have fun

 

i've used just the bottom layer many times. just use copper spray and torque the head bolts a few more ft/lbs like 70-75.
twincammike1 still has the same setup after 30,000 miles on a motor i built over 3 years ago. b18c5, endyn 81.5mm pistons, 1 layer gasket. 12.5:1 compression, jun3 cams. 197@ the wheels, and almost 30mpg. motor still runs like a champ. no headgasket issues at all.
i think topspeed86 also has a 1 layer on his car. all of us used to run that **** when i lived in florida.
