Spark. Plugs

Post by packuk » Tue Apr 17, 2018 9:58 pm

Hi. I have a 41 clipper which has a 8 cyl engine with 10 mm plugs , did the plugs ever have rubber.shields to stop dust and debris going in moulding hole in head. If so where would I.get them.

Perhaps you're thinking of such shields that Chrysler used on the L-6 engines for some years but no, Packard never used anything like that. In later years they did have an accessory rubber boot that just slid down over the porcelain of the plug of minimize shorting when the plugs were wet, but these were for 14mm plugs and still left the plug well in the head open.

It is important to blow any debris from the plug wells before removing the plugs. I failed to do that once and a small pebble fell into the cylinder which resulted in a hole blown in the top of the piston.
