Engine knock after rebuild.....need advice Options

[LCOX]

This on going problem started after I rebuilt my 1.8 engine last year. Since then I haven't driven the car and I've put it on the back burner and finally ready to face it again.

Rebuilt the 1.8 with all new bearings and new rings. There is a definite engine knock at idle and throughout the rpm range. This is not a ticking noise like a valve out of adjustment but a bottom end knock.

I did check valve adjustment and everything I could think of. When I pull the #3 spark plug wire the knock almost completely goes away but not completely but definetly better

A couple members said it was probably a rod knock so with the engine in the car I pulled the head and #3 piston and cylinder and tried another rod but the knock is still there.

So I guess take the engine apart and look for a mistake I made on the bottom end rebuild right? Anything else I can try? Thanks in advance. L

The heads will hit the suspension console long before they slide off the longer studs.

You can probably slide them off if you disconnect the engine and lower it ~6", but by that point you're only a couple of wires and cables from completely removing the engine from the car anyway. And it's a heck of a lot easier to deal with it on the bench than hanging halfway out of the engine bay.
