REGAL Slight tick after Seafoam

[CaliWagon83]

So I changed the plugs last weekend, and ran some Seafoam aerosol through the carb, and put a can of Seafoam fuel treatment in the tank. The car starts and idles a lot smoother (except for an occasional stumble) but I have noticed a slight tick at idle that I hadn’t noticed before. It’s not severe.

I don’t know if these engines have adjustable rockers, or if it’s maybe a lifter that’s not pumping up all the way (the even-fire 231s have hydraulic lifters, right?)

Any experiences or tips appreciated.

Adjustable no, hydraulic yes, how may miles is your tick on the drivers side.

Unfortunately that's a common problem after running seafoam in these older engines. More often than not, it leads to needing work shortly afterwards

try some in the crankcase.. I've used seafoam and I liked the results.

Fuel pump?

turn up the radio usually not a big deal in the old days we would as rislone to quiet the noise have a good weekend

Would changing the oil help? I didn’t put any Seafoam in the crankcase, but I’m wondering about blow-by, and if it thinned out the oil. Most the car has been driven since Seafoam is around the block a few times.

As long as I can get another 5-7 years out of the engine, I’ll be happy. At most, I’ve only been putting a few hundred miles a year on it.

Just shut the motor off at car shows, and no one will be the wiser.

You probably have years left. Changing the oil won't hurt, but try an old mechanic's trick. Put the handle of a long screwdriver up to your ear and touch the other end various places on the motor to try to isolate the ticking - I've had fuel pumps start to go bad that sounded like a ticking lifter. Just don't shave off your nose in the spinning fan...

Fuel pump is relatively new. Granted, it's probably made-in-China crap from RockAuto, but we replaced it when we went through the fuel system rear-to-front. Now I'm trying to isolate the intermittent stumble. It has new plugs and wires. I'm wondering if the distributor could be on the fritz. All-in-all, it runs pretty good for what it is.

The reason I asked about the right bank tick is the poor oiling to that side. If you don't already have one - recommend installing an oil pump booster kit, cheap and easy to install.
