Thread: Here I am Again Part 1:2

Tweet

Well----in the pic I notice that besides the damage to the push rod and rocker that the adjusting screws on those two rockers only just barely come thru the lock nut whereas on the other cylinders there is quite a bit more sticking up----can you teoo why? Shorter pushrods, shorter valves, worn out cam lobes, bent valves????

How probable do you think it is a bent valve? Wouldn't the motor smoke a little bit if so?

I am not familiar with the valve set up on this motor, can the damaged rocker be replaced individually or will the whole set have to be replaced?

Here is my diagnostic thus far:
1. Cam button (if so equipped)
2. Warped cam
3. FUBAR cam lobes
4. Bent rods (but what caused them to bend?)
5. Improper valve lash (too tight/ too loose)
6. Incorrect push rod size
7. Cam spacer (if so equipped)
8. Valve float
9. Improper valve train (as so suggested by Daffy427)

What do you guys think?

Are those PRO COMP Heads????, looks to me as the valve train is the wrong set up but also your push rods should not be that close but it just goes up and down so not much problem there, I would have to agree with the valve train floating and improper valve adjustment.

No, they are the iron heads that were on it from production...

Turns out, this happened when cruising down the highway at 60mph, about 2400rpm then out of nowhere, it happened and that one head's exhaust was making the classic "briggs & stratton" sound.

Engine builder and FE Ford expert still believe it is hydrolock from oil pressure.
Don't know what the pressure is because gauge does not work, working on getting a new one... they said oil filters without a bypass built in will cause oil pressure to rise...but doesn't the oil pump have a pressure release? It is a high volume pump in a 10 quart pan.
