So I did a complete timing belt job, new TB & BSB, pulleys, seals, tensioner, WP, etc. All the marks aligned perfectly, after turning the crank 6, 12 and 18 times. Tension looked fine, used a DIY pulley tool to get the torque right, etc.
Only possible issue is that the tensioner-arm gap MIGHT have been just a hair under 3.80mm, but probably not. I understand that if it's below 3.80mm the arm could his the tensioner under acceleration and lead to a tooth skipping.
I've run the car several times and I didn't hear or feel anything that seemed like a tooth skipping or anything worrisome from the engine. But I want to make sure. Is there a way to check alignment with the lower TB cover on?
I see timing marks on the lower TB cover around the crank pulley, and I can easily remove the upper cover to check the cam sprocket timing marks. But does that allow me to check alignment? I can't find a mark or notch on the crank pulley. Is there one?
