Does anyone know of a good way to check the hydraulic lifters on the 24V? The shop manual doesn't give much info about the lifters.
I'm trying to nail down a rough hot idle & intermittent 1223 code that occurs only at idle. It's been a problem on this car for quite some time. Ignition modules, coils, plugs, tbelt, pulleys, etc all fresh. Cam timing (with dyes) is spot on. No vacuum leaks & freshly serviced injectors. Recent O2 sensor as well. Passes emissions (no emissions testing at idle in TX) with flying colors.
The motor makes quite a ticking noise once it gets up to temperature, & I was thinking that one or more lifters might be stuck. However, a leakdown test revealed no such problem. Of course, I did the leakdown test with a cold engine since I'm also addressing some cooling system leaks. Even if I had the chance, I don't think I'm fast enough with these cars to remove everything necessary for a leakdown test & still have a hot motor.
Thanks in advance for any input.
