I haven't messed with a 2003 lately, but all the rods I've seen, didn't connect to anything, they get tightened up with their adjusters inside the lifter and the rocker, and there is just enough play to twist the rod back and forth, and it is set. The short one of course will only fit one side and the same with the long one. Now your bike might be different. So i will leave it up to you, please don't don't write back complaining I didn't know what I was talking about, because I already admitted that. Hope this helps.

Witch way do the pushrods go in the pushrod blocks on a 2000 lowrider


Hi Anonymous, for big twin engines solid pushrods come in different lengths, depending on the manufacturer all four could be different lengths or only three will be different and two will be the same. Push rods that are the exactly the same length go into the intake slots. Sportster push rods will come in two different lengths the short ones go into the intake slots and the long ones go into the exhaust slots. For Big Twins that have four different lengths the order from shortest to longest is as follows: Rear Intake, Front Intake, Rear exhaust, Front Exhaust. Some OEM push rods will have colored bands that can be mismarked or the bands could partially or fully wear off, thats why I only go by length. Good luck and have nice day.

What is the push rod arraingment and what cylinders are 1-3-5,2-4-6


The intake pushrods and exhaust pushrods are different lengths. To distinguish the different pushrods, paint has been used, although this paint may be hard to identify after prolonged use. The intake pushrods are color-coded orange and are 6 in. (152mm) long. The exhaust pushrods are color-coded blue and are 63/8in. (162mm) long.

Here is a picture of the cylinder marking:

Were does the singal red push rod go the intake or the exhaust


The latest book I have is a 2002 model book and it says that the pushrods marked with three pink bands and are 10.800" (274.32mm) are exhaust pushrods. The intake pushrods are marked with a single brown band and are 10.746" (272.94mm) long. Lay all the pushrods side by side and check the lengths. The long pushrods are the exhaust pushrods.

Good Luck

On the 92 chevy lumina eurosport 3.1 push rods on the heads you gave the configurations but no matter which way I put them in the long is too long but the short is too short. also when I tighten them down...


the euro sport is the same as the lumina base just with a body kit, stiffer suspension, and dual exhaust.

but on the 3.1 engine the pushrods are all the same length, but depending on the stroke each cylinder is on the pushrod may be in a different position.

you are assuming that every pushrod should be in the rest state. that is not true. if the cylinder you are installing the pushrod for is on the intake stroke when you install the intake valve pushrod and tighten the rocker arm nut the valve will procede to open like it should be open for the intake stroke.

this is normal and its nothing wrong with it.
