Hi everyone,
Suave here from Canada - happy to join this community! I picked up a 1979 Lotus Eclat 2.5 yrs ago and recently had the engine rebuilt, but unfortunately I cannot get it to run smoothly, and I'm hoping you guys can help!
After some research, I determined that my issue might be incorrect timing.
The engine appears to be equipped with the camshafts that have 2 grooves (see picture below, this appears to match camshaft Spec 5 as per the workshop manual). Can anyone confirm that I'm interpreting this correctly? The 2 grooves can be seen clearly between the sprocket and the cam housing.
The matching cam sprockets should have yellow timing dots as per the manual. However, my cam sprockets have the blue/red timing marks on each cam. See pic below. The blue/red timing marks are facing towards the engine (toward the rear of the car).
This would indicate that I've got non-matching camshafts and cam sprockets... can anyone confirm that my findings are correct?
Would adjustable cam sprockets solve my issue?
Any input would be greatly appreciated - I really need your help.
