stem seals change with heads on

gazdon · Oct 14, 2012

isit possible to change the valve stem seals with the heads left on 4.6 v8 as i did change seals in the past on a 2.8 xr4x4 with the heads on by putting rope down the bores to keep the valves up.

take a old spark plug save the hex and threads knock everything else off it and Braze a air fitting to it, screw back into the spark plug hole and let the air keep the valves closed

I'm not sure how much of a difference the stem seals actually make. You dont need to go too far back in history to find that the same basic engine was never fitted with them at all. I think it was just one of the little things that LR did to improve emmissions.
