Hey guys I have a f22b1 11:1cr boosting 6psi. I am having blow by in my headgasket....... any suggestion on making it seal better. I've had this problem many times before. I just keep on changing headgasket until it works. But this time i wanted ur input............

 

did you mill the head when you change it? Make sure surface is clean, copper spray, and 3 step torque

 

head got milled... yup
clean.... yup
copper spray.... nope
3 step torque... yup

how much of a difference does the copper spray help?

 

copper spray definately helps it to seal initially but if you are blowing them repeatedly then thats probably not your problem. definately worth the $4 - 5 a can though.

you milled the head flat, but it's possible the deck is warped, unlikely, but possible.

have you tried a solid copper headgasket? there are a few companies that will make you one custom for about $125. not too bad considering that they are reusable. they are harder to get sealed initially, but they stand up to high cyl pressures well.

try doing a 4 or 5 step torque sequence.

 

what did you torque it done too and these are new head bolts right?

 

Did you torque it down and then re-torque it after so many miles? Try a cometic headgasket. They're what a lot of turbo people run and they're considered one of the best.

last i checked cometic had no listing for the Accord, which if still true... is unfortunate.

how many TIMES have you reused those bolts? i'd be looking into studs to clamp down all that business. hows she running otherwise? you're running the setup I'm working on now

it's true, but there are a few companies on the internet that do them custom. Just send them your old HG as a template and they will do you up right. couple of them even had several thicknesses of material for the HG so if you needed to back the CR off a little bit for whatever reason, you could.

 

I am using ARP STuds. And I torque them down according to honda spec. however i did go about 10 pound of torque over stock.

 

I have ARP studs right now.... other than that she running great on 6psi.. Pulls very hard. Also I just finish my 5spd swap at the same time..... so its really fast compare to my last setup (auto, @10psi). I broke 3 auto trannys before the did the swap. However I just took the head off my blowby is at the back of #4 cylinder.

 

Is it ALWAYS at the same place??? Sounds like warpage on the block if the head has been shaved. If you're using honda or felpro replacment gaskets they're whats called "multiple layer metal" head gaskets and are VERY picky about how flat a surface is.

copper spray is one way, another way I've done it is using spray primer and then put the the head back on while the primer wasnt WET .. or DRY.. just a bit tacky. then after you torque the head down let her sit overnight.

 

I have seen the honda and the felpro gakests and unless the deck is warped substantially the head gasket is pretty thick. And after you put it on it does get squeezed down to thin piece of metal. Try the copper spray I coat it till you cant see the gasket no more and put it down while it is still tacky. Also make sure the dowel pins are the right ones are are seating in properly with the holes clean. That could prop the head up alittle too high

 

Would u recommend a copper headgasket? Which is better copper stray or the primer?

 

copper was a great headgasket, back in 1973... in the year 2003 we have MUCH better options! I think this is going to come down to you custom ordering a gasket, which isnt near as much money as you might think.

 

you need a cometic hp headgasket son

ss fire ring

 

what options do u have or suggest?

 

I say since you have done it so many times that you might as well try the stock honda gasket with copper spray before spending for the cometic. it might just work

 

thats what im working on i guess. Hopefully it works, but i will probably order a cometic anyways...

 

my cometic should be here within the next few days, cant go wrong with a stainless steel fire ring if you have serious pressure sealing issues

plus they have a nice range of thicknesses i paid about 100 for mine

is that the same thing as O-rings?

 

just coat your block and head w/ JB Weld and call it a day.

 

Im not a big fan of fire ring or oringed heads/gaskets. When you're dealing with an expensive boosted car of any type, sometimes a little give in the gasket is OK. Better a 80 bucks gasket than an expensive shortblock.

ever read the package? they talk about somebody fixing an engine block with it.

 

ok guys, i got a new honda headgasket i sprayed some copper spray on it, put it alla back together..... and this is what i get.......... I can drive the car.... easy.. for about 15-20 min then my temp gauge will start to rise. note that i wired my fans to come on all the time.... and the temp is still rising. I was out last night and boosted on it a little be... and i can hear that my gasket didn't seal... any suggestions?

 

your not re-using the stock head bolts are you?

BTW, 11:1 comp pistons and turbo w/ out a properly prepared head is bad news.
