another ticking question - 380 SE

85 380 SE 188,000 miles, new chain, etc., at

well, we've developed a top-end ticking noise on the
left side and i'm wondering if anyone can give me some

it is constant in conjunction with motor speed, just started about a week ago when the temperature dropped; haven't taken the valve cover off yet (waiting for the weekend and hopefully 50 degree weather).

when i started hunting it down, it sounded more in the middle of the left valve cover area, so i'm thinking (hoping) away from the chain and guides. on further listening with my shadetree stethoscope (large, long screwdriver affixed to the large right ear) it sounds like it's coming from the area around the injector valves and beyond the air distributor hose. of course i know sound transfer can be tricky and/or questionable, but anybody want to take a shot in the dark?

i'm in the light mechanical ability range but have strong supporting cast (in other words, they tell and i do what i can) and i will pull the valve cover this weekend. i know one cam lobe near the fire wall is pretty banged up, but this sounds closer to the fuel
distributor and air regulator to me. do the injector valves tick like that when going south?

thanks in advance.

roger that. thanks jdc.
Stjernegrisen --

when you say free-play, i take it you're referring to
free-play at the cam towers? (sorry, this is a new
repair level to me. i'm used to water pumps and belts
and starter motors and low-tech repairs.)
thanks. i got you. after thinking about it, i
realized that's where you were talking about.
if that's the case, are we then talking about thrust
washer/shim adjustment? don't i need that tool that
fits over the ball stud to measure the gap?
thanks for the direction. i've seen the photo of the
follower damage in an earlier post. i'm starting to get the picture (sorry, couldn't pass that one up).

i'll post a follow-up when i get that cover open on
saturday. thanks for all the responses. i'm sure i'll
have more questions and i really appreciate the support!
that was my next question -- valve spring compressor.
that's a good price compared to a shop doing it, but i suppose it needs to be that one. (more concerned about timing the repair.) i have a BAP GEON local, so that
part's easy.
