Is my iron ready to go?

Hello guys,

I just finished preparing one of my irons. I'm just wondering what do you think of my Hylomar job.

Thanks!

Hahaha, except for the smiley face! Did I put too much Hylomar? Atkins says to put a lot of Hylomar, Mazdatrix says to put a tiny little bit amount of Hylomar.

That seems excessive to me. I've stopped using hylomar completely, just vaseline on the o-rings and the older formula of The Right Stuff (still have half a case, woot) on the 'legs'. It probably wont affect anything but if I were you I'd skim the hylomar off the inner o-ring where the corner seals will make contact. Probably wont do anything but no point in having extra goop that you've got to burn off during initial start.

Just use a thin coat, but dont go over the plate where moving parts get in contact with. If you can get your hands on a rebuild dvd or something like that , get it. I dont know your experience rebuilding engine, but if you dont have any, it will help you a lot.

I have seen people using Vaseline but I felt I was too rich to only use Vaseline.

The extra amount will be burnt on initial start anyway I assume?

On Atkins's DVD, the guy puts a lot of Hylomar. On Mazdatrix's DVD, the guy puts close to none. Both are very different!

The hylomar is use just to hold the water seals in place.

The excess hylomar will end up in the coolant system so you don't want to use too much. I do not like Vaseline as it tends to make orings swell. Put a thin coat of hylomar. Wait 5-10 minutes for it to get tacky, then install the orings. Also, you DO NOT want hylomar anywhere but where the orings make contact. The bottom left and right of the irons need a thin coating of silicone rtv to prevent oil splashing up from the oil pan from leaking. Hylomar will not seal out oil on its own without a gasket.

Word. To be honest the vaseline/engines I'm referring to get torn down after 20 hours and even then I just trim the swollen outter orings at a 45* angle and put a dab of superglue on them.
