Doing a headgasket on a d16 and this happened somehow in the process.

Any thoughts?

Should i try it anyway? Maybe add copper spray? Or is it gunna have to be machined?

 

That engine looks toasty. How do you manage that? I don't know if a machine shop can remedy that.

 

time for a nice swap. or maybe someone can weld it than file it down?

 

Looks like it's time for an overbore and rebuild... that pic does not look healthy :-(

 

Should´nt be a big problem. From the looks of it, the scratch does´nt go all the way through to the "coolant side"...ends just before it, maybe you could use some 2k aluminium filler or something similar...Hondabond ?

 

The cylinders look pretty bad anyway. Clean up up good, put some JB Weld on it and file it down flat with the block, hope for the best.

 

what 94 said....
you have nothing to lose.

 

Next time dont pry the head off with a screw driver lol. Naw aluminum filler and get the sanding right. Then start saving for a new block....that fix could last a week or forever who knows

 

maybe its worth mentioning that there is no real depth to the mark.

i feel it when i drag my fingernail across, but it doesnt catch it at all.

the pic makes it look like a gash, but its really not.

still trying to decide on what route im taking. doing lots of research,

anyone ever heard of hylomar?

 

I would have a welder weld it a bit then file it down!

 

u got a little something in ur coolant there .. lol

 

uggghh...yea thats why im doing the head gasket lol

 

seems a lot of people think this as well. ill start looking more into it

 

haha i was just messin with ya .. hope you get it fix .. wasnt tryin to be ignorant or anything

 

If your fingernail barely catches it...hrm...perhaps copper spray MIGHT work...then again, maybe it won't, or at least not for very long

if i were you id just slap a new headgasket on there and hope for the best .. it honestly dont look like it will be any problems
.. just my opinion though

 

Or just yank the motor and have the block milled if you're REALLY paranoid about it

 

that doesn't look to bad, just use a die grinder to smooth things up a bit and you should be ok or use a different head gasket material.

 

What? You're suggesting that removing MORE material off the block will correct the problem?

 

No way, I would NOT recommend taking a die grinder to a blocks surface!

OP, just put some copper spray on the new headgasket and install it. The spray should help fill in some of the imperfections.

I don't want to start a copper spray vs no copper spray war haha, I've tried both methods and both methods worked fine.

 

hylomar could work but use it sparingly. hylomar doesnt ever really solidify and if it gets in your water jacket it could cause problems with your water pump. its made for high temp, moderate pressure uses so you should be ok. just use a file and make sure you didnt cause any high spots on the blocks surface then use either copper spray or hylomar and a new gasket and hope for the best.

btw we use hylomar where i work. we use it on gas compressors worth 1/4 million dollars. should be ok for a honda....lol. also the same thing that saab uses for oil pan gasket.
