You shouldn't have to adjust the valves every few thousand miles.

How did we get from fuel pumps to spark plugs on this message?

What do you think of NGK 2438 plugs?I have used the NGK 2438 18mm spark plugs in a stock but blueprinted Ford Y engine and they worked just fine and held up well over time. That engine had electronic ignition which helps with the overall life of the spark plugs. That same NGK spark plug has also been used successfully in a stock iron headed 390 Ford engine also with electronic ignition. The only issue I have with the 2438 NGK sparkplugs is that it’s a 'fit all' spark plug and only available in one heat range. For a performance Ford application requiring a 18mm plug, a colder heat range spark plug would be desired.

" I am slowly moving away from Autolite to NGK on the shop built engines due to having a better heat range selection with the NGK’s as well as having some brand new Autolites not firing from the git go. The Autolites have been coming from both Mexico and China but it is the China made Autolite spark plugs that I have had trouble with. It seems to be potluck at the parts store on which country of origin the Autolite spark plugs are from. I now do a mandatory ohm check on the new spark plugs before installing them."
THANX! FOR THAT INFO TED ...

Good morning, Ted. What plugs are you using with the electronic ignition? I use the same spark plugs as is being used on a breaker point ignition. For the ’55 Ford with the electronic ignition conversion, I have been using the Autolite #46 spark plugs gapped at 0.035”. I am slowly moving away from Autolite to NGK on the shop built engines due to having a better heat range selection with the NGK’s as well as having some brand new Autolites not firing from the git go. The Autolites have been coming from both Mexico and China but it is the China made Autolite spark plugs that I have had trouble with.

Well then. Thanks for that write up Ted. Looks like I'll be waiting a few more years before checking them again.

How often are you supposed to do it? I was thinking every 10,000 miles or so?Probably a bit of overkill but a 10K interval for setting the valve lash would be okay. That would coincide with the old once a year tune-up interval back when those cars were daily drivers and were also in need a set of spark plugs and points. Unless the car is a daily driver, then the valve lash adjustment could potentially be put on a two or three year interval rather than a mileage interval. I check the valve lash at 40K mile intervals on my’55 Customline with its 272 Y. That coincides with when I change out the spark plugs for new ones. Electronic ignition has made the old 10K tune-up intervals sort of a moot point and definitely overkill. The last time that spark plug change interval came up, the valve lash was checked but needed no changes so unless I hear something going on under the valve covers, they will not be checked again until the next spark plug change interval. The car currently has 335K miles on it while the engine has 223K miles on it since the rebuild and the addition of the E4 Isky camshaft. This is just the way I do it on my own Y so don’t let this be the final word on the subject.
