Recently did the springtime adjustment on the bus. I like to plot the data, it helps to look for trending. Still pretty early going on this engine but so far I feel comfortable with how things seem to be settling in. If I find a valve at 0.007" I've been leaving it instead of tightening it up since things still seem to be moving around a bit. These are the "as found" clearances for the rebuilt longblock from A.C.E. in Salt Lake:
Compare that to my anxiety inducing data from the J.C.S. engine that it replaced:
Looking at those numbers bothers me even now. Man I was getting sick of crawling under there every few hundred miles only to find that the adjustments were off.
Listen to your engine, it wants to talk to you.

Re: Valve Adjustment Data
Very nice. Spread out the data a little and it will be a fascinating read of the aluminum iron magnesium sandwich-that-is-your-engine.sped372 wrote: I like to plot the data, it helps to look for trending.

Re: Valve Adjustment Data
interesting!! my present engine is from JCS and i've noticed with milage (1500 miles or so) the valves keep getting tighter. i've retighted the heads twice in the last year & 1/2. but i do have this running on the hot side problem (which is why i'm always checking the valves/timing etc). i got to get around to hooking up this external oil cooler that has a fan i found in a parts box.

Re: Valve Adjustment Data
How many (total) miles do you have on it? What's the backstory?
