Vauxhall 1.2 16v engine keeps spitting out cam followers

Wouldn't it produce very obvious wear patterns on the roller if one was seized? I think insufficient preload allowing the followers to rattle loose engine off is a more likely explanation.

The one that's dislocated in the pics has some pretty bad wear marks in the surface of the roller.

I didn't spot that in the pic, but if it's there that would definitely support the theory. It should be obvious either way with the roller in your hands.

Hi did you ever solve this problem ? I have a
1.4 doing the same thing thing on 2 inlet valves ... I can almost lift out the follower , everything is clamped down tight , I have a spare head with the same cam setup and have swaped over cams rockers followers etc all ok in one head nice and tight but gaps in the good head

Did you also swap over the hydraulic tappets?

Yes everything from one head to another , all ok on one head but loose on my head , parts off my head fitted to other head and all ok , no bent valves etc , it's like the little rappers go in the head too far ?

What are "little rappers"? Do you mean the tappets? Hydraulic tappets can get gummed up and stick in one position.

Little tappets ... spell check error ... everything is free , torq set , turning fine but the tappets are loose on 3 valves when fitted to my head , all fine in the other cracked head , only reason I can seem to come up with is heads damaged somehow and the tappets are resting to deep in the head , the head on the pie on the start of this thread has the same problem , I'm just asking if he solved it .
