while searching for the cause of the incessent popping in my carbs, i decided to check my valves. turns out the adjustment screw for the # 4 exhaust is MISSING. i don't know how i did this having adjusted the valves last year before installing the engine. also the nuts on the rest of the rocker assembly are not 13mm , they are larger and possibly american. what the hell do i have here and can i replace the #4 exhaust screw or do i have to pull out the whole assembly.

Cook something ... sell it .... buy new ones .... and don't overtighten the lock nuts and the will last for a long, long time.

If you look at it, it's a straight screw ... it doesn't really car which way it comes out of the threads other than the screw driver slotted end could be spread (mushroomed).
Clamp it in a vise and apply force ......... |

Naw, it's like socks in a washing machine ... winds up getting sucked into a black hole and spit out on the moon. Next trip, they'll find it.

It CAN get into the engine via the oil return slots for oil in the pushrod tubes..
the larger 10mm adjusters use a 14mm hex, not a 13. This is why these are TORQUED every time they are tightened.. They will come loose if given the opportunity. |

I just went and investigated my spare case which was a T4 bus unit, the slots for the oil drain in the lifter bore are 3/4" x 1/4" approx. The lifter is not in the way cause the oil has to get back to the sump somehow, Additionally I stuck a lifter in and sure enough there is room. Both your adjuster and my rocker not could fit through there and I am about to got diggin. Recall there are two circular covers in the sump, perhaps a magnet on a stick will fish em out... good luck with yours chef.

Like I said, the 10mm units have a 14mm hex, thats nothing new.. Always been that way..
The nuts can make it down the tubes and end up in the sump through the oil return slots, I have found these in the oil sump before upon tear down. Everything on the engine has a torque... |
