Afternoon all.
On adjusting the valve clearances I noticed that the front cylinder inlet pushrod would not rotate, even with the adjuster freed right off. I adjusted the play properly and took it for a run - everything perfect. Inspection cap off - still won't rotate but adjustment fine. I took the adjuster out and lifted the rod, I think I can feel it bringing the ET29 (lower cap) up with it until it stops/won't come any further. Gentle upward pressure with a rag and some pliers won't bring the pushrod out any further.
I suspect that when work hardening the bottom end of the rod has gone slightly oversize and locked itself into the ET29. I guess this is bad news and will need to be resolved?
I've ordered up a new pushrod but was looking for advice from Forum members on two questions:
1 - Anyone come across this before and am I likley to have identified the problem correctly?
2 - How do I go about changing the pushrod safely - I read in an old MPH of a guy who dropped one past ET29 down into the engine and got it stuck fast - having then to strip the head off - no thanks!
All advice gratefully received.
Cheers all
