Cold Valve Lash Question

One more thought. I see you’re in Boise.

If you drive the car when it’s cold (I’ve driven my car when it was in the single digits) you can get the lash to close up and when cold. Then you can get some dead cylinders when you start it up again.

My car stays in the garage. Several years ago we went to my sister in laws for Christmas. It was 12 degrees when we left the house at noon. By the time we headed home at 6 pm it something crazy cold. Like 4 degrees.

When I started it up after sitting outside in the cold I had 3 or 4 cylinders that were missing because the lash closed up enough it was holding some valves open.

Once it got some heat in it they started hitting again but it’s something to be aware of.

I’ve also had customers with solid roller lifters on hydraulic roller lobes that cold lash at .004 and they had the same issue.

As long as you know it then you understand it.

Just something to keep in the back of your mind.
