So I have a 65 rambler 440 with the 196 engine. The intake plate appears to be sealed with an entire tube of rtv.
I can get the felpro set locally and wanted to know if sealant is recommended when I install the new gasket? Thanks!

In my opinion, NO. When you get the gasket set you'll see that the gasket is thick enough not to need sealant. Also remember the inner plate bolts are actually head bolts and will have to be torqued correctly.

is the head off? taking out 6 bolts is gonna mess with head sealing. i need to pull my 1bbl plate off to put on a milled-out one and i'm afraid to. the gasket is thick enough to not need much if any sealer as rockandrambler says. i use a light coat of some non-hardening mostly to make myself feel better. cheap silicone makes a lousy gasket. most of them are not oil or fuel compatible. i use only Permatex brand and use the correct one for the application. they cost a lot more than the cheap GE crap (i wouln't seal a window with that crap). but i did assemble a 195.6 OHV with zero gaskets other than head and oil pump, not even pan. i used Permatex Right Stuff. it's $25 a can. it WORKS. it's not RTV silicone. it's great. when the engine came apart 10 years later the stuff just peeled off nicely like a gasket would. great stuff. but the gasket is perfectly fine! |

It seems like this a 'vintage engine' thing, where the 'old school' gasket sealers like 'Indian Head shellac' (?) on a thin gasket would be 'best' ...to reduce 'squish' and/or distortion caused by torquing the six head bolts down (with less torque applied to the install the other intake cover perimeter bolts)
http://www.stolzeclassiccars.nl/aanbod/3461/nash-healey-53-roadster/ Seems to be 'worth doing it right'; it is a famous engine design, for winning races, as installed in the wonderfully made Nash Healey sports cars: Edited by amcenthusiast - Aug/29/2018 at 8:21am |

HOLEY KARAP THAT'S BEAUTIFUL!! probably has headgasket problems too lol. but at least it looks good doing it! the real problem with the 195.6 head is the design itself. there's simply not enough gasket space, and as bad, the bolt spacing and placement is awful. i wonder how that earlier engine is different. FARNA/Frank, do you know? it's from a different fork in the evolutionary path; "our" rambler motor wasn't that Ambassador motor, but the little econo flathead, that got re-headed OHV. but clearly the same approximate, base design. i think that motor there has 7 mains. which improves head sealing -- because the cylinders are further apart, because of the three extra bearings, hence gasket surface area, and a better bolt pattern. but it's longer and heavier. i've always wondered if there' s not some other blocks and heads adaptable. it's not like anyone's ever cared about this motor or its lineage much so it's entirely possible there are possiblities in here. |

That's the 234.8 engine, I believe. The exhaust is similar to the 196 as it's on the left side under the intake, but it's a pipe clamped to the block like the flat-head. The Nash-Healey (that's what the photo is of) supposedly had a special head, but I believe the casting was just altered for the dual\side draft carbs, nothing more. It may have had larger valves though, I'm not sure. I don't know if it had the issues the 196 OHV did or not, but it was more common to re-torque head gaskets in the 40s and 50s due to gasket materials. Part of the problem with the 196 OHV design is it is a conversion from an L-head with minimal changes to the block, which affect sealing surface area and head bolt location. There were seven mains in the 234.8 and similar OHV sixes, and it's longer than the 196 -- more comparable to the 232 family.

I always loosened ALL head bolts when replacing the intake plate,then torqued back down in sequence. I'd think that loosening all the bolts on one side could cause a sealing issue, and that engine has head sealing issues enough without introducing another factor!

i don't have Nash manuals, but google searches (without being exhaustive) say that the Nash Healey got the Ambassador engine, which is of course as you say, the 7-main engine. makes perfect sense for man reasons. 7 mains would provide more/equal cylinder spacing, eliminating the major small-six head sealing issues. probably the same undersized, crappy mushroom lifters. not really complaining, this stuff is old! i'm fairly sure, though based only on one engine, that the crank flange changed in the late 50's, from 4 bolts to 6. same flange, just more bolts. |
