strange loud ticking noise under plenum

At the risk of asking the obvious, is the oil level correct? No offense, but some times it's the obvious things we overlook when looking for the complex.

NO offense taken..I did check the oil three times. The level check out full at the max. the only thing i did differently was during the oil change i did drained the oil cooler also. I have to check that out too if i tighten all the lines.

Injectors can tick also......they can tick they can tock, they can go like the hand on a door, knock knock.

Sorry read Mr. Brown can Moo too many times, its an impulse.

Test confirm today using Mac tool oil pressure testing kit. I have no oil pressure. The gauge read at 0 in three times out of five testing sessions. I guess new oil pump is in order.

A failed oil pump would be highly unusual. I don't have an oil flow schematic in front of me but in believe the oil filter is before the sensor in the flow from the pump. I would change the filter and give it another thry.

I thought it is unusual for the pump to fail like this too. One day the motor run top notch the next day nothing. The ticking noise is from the lifters due to no oil go up to lube them. I will give it another test tm. I am trying to fine the Helm manual when i am done posting this thread.

Shayne,
The only thing out of the ordinary during your oil/filter change was draining the oil cooler. A shot in the dark here...... but at any time did you ever put rag or paper towel in the oil cooler, lines or oil filter adapter to help control the mess that goes along with draining the oil cooler?

It just doesn't seem likely to me that your oil pump suddenly failed, nor does the filter seem likely. There are bypasses for both the oil cooler & oil filter to maintain oil flow if either is plugged. However, if there was some foreign material blocking flow to the oil filter and the oil filter bypass, then you would see 0 oil psi at the oil filter housing sender.

Until this gets tracked down, avoid running the engine, because ALL oil goes through the oil filter adapter housing FIRST, so nothing is getting oil, lifters, cams, crank, rods, etc.

If you think there is is a possibility that something may have gotten in there during the oil cooler draining, let me know & I can send you a spare oil filter adapter housing to try. it's not a big job to switch them out.

Right now, that's all I can think of.

HI Jerry,

When i disconnects the oil coolers i did not cover it with rags. I simply put a rag and paper towels under the fittings so oil can collects on the towels (it wasn't much oil) when the motor is cold. I removed the oil cooler and drained the old oil out from the bottom using an L wrench. I reverse the procedure and everything went back together as it should... then fill the motor with oil. So i don't think anything would of gotten in the motor. My brain's been storming like crazy thinking what could have happen?

After the first start up i added 4 more quarts of oil.

Not really. Oil from the pump also feeds directly to the oil cooler, as well as to the oil filter. There is an oil cooler thermostat in the oil filter housing adapter that prevents oil from passing through the oil cooler until it reaches a specific temp which is above normal driving temp. It operates much like the coolant thermostat except with a sliding sleeve valve.

Any air trapped in the oil cooler would "bleed" into the filter loop as the valve gradually opens & then on through the system as the valve cracks open. it is not a snap close-open-close valve. In all probability, air in the oil cooler loop probably bleeds around the sliding sleeve valve without it ever actually opening, allowing all air in the system to be processed out.

At this point, I'm not sure what's going on. If the oil filter was plugged for some odd reason, the oil filter bypass should/would open. For no pressure, the bypas would also have to be bad. Changing oil filters is certainly an easy & inexpensive test and logical next step.

Do you have a low oil pressure indicator light illuminated in the dash panel? If it is working (big question) it would illuminate. If low pressure and no light, it could be the sensor plug, sensor or the bulb in the panel not working.

The low oil pressure sensor is directly in the oil pump discharge circuit and would be the best indicator of oil pressure before all the cooler & oil filter valves. If the low oil pressure sensor weren't so hard to get to..... pulling it out & testing pressure there would definitely verify pump output.
