Does anyone know what the max variation is between holes?
This is on a 02 ALH car.
I left my Bentley at home.
I have one that is;
#1, .038 or .9652mm
#2, .036 or .9144mm
#3, .042 or 1.067mm
#4, .037 or .9398mm
These measurements are in inches as my dial indicator doesn't read mm
so I converted then as accurately as I could,
Using these measurements I'll need a 2 hole gasket which is what it had but I'm more concerned about the variance between piston protrusion.
Timing belt broke and destroyed everything in the head, all 8 valves, all the lifters, broke the guides and damaged the cam.
Pretty sure the last one I measured was closer than that(it had crashed, but not so bad), you might be sporting a bended rod or 3.

That's kinda what I was thinking as well but as I didnt have a Bentley at the shop I can look up what if specs are as to max dif between holes.
So if he slightly bent the rod, but all pistons are within spec for the 2 notch.. Will it still work?? I mean if they still protrude they should still make adequate compression?
I suspect it will run just fine with the current specs.
Kinda sounds like he is going to just fix the head and give it a try.
anything more than a .004 variation cylinder to cylinder in the pockets requires you to pull a pair of pistons & Rods
So By Frank06, you are just out of spec...
