RW> No. One could make an attempt to fix that by removing said lifter, take RW> it RW> apart and clean it, maybe replace the spring. As long as there is engine RW> valve spring pressure on that weak lifter, it will leak down and need to RW> be pumped up by engine oil pressure before the valve tap goes away. My original engine didn't have that cold engine tap - so I guess they used different parts on the Jasper rebuild. Not a big deal, since this is really minor and not causing a problem.

I'll give that a try. It isn't easy to find synthetic in 10w-40 - most are lower. My thinking was since it doesn't do the "cold engine tap" when it is warmer outside, the oil is more lean and can be pumped up quicker when you start the car. - Mark --- WWIVToss v.1.50* Origin: http://www.weather-station.org * Bel Air, MD -USA (1:261/1304.0) SEEN-BY: 3/0 633/267 640/954 712/0 313 550 620 848 953 @PATH: 261/1304 1 266/512 140/1 261/38 712/848 633/267 |
